Daniel Rossberg (Mar 14 2019 at 17:26): Daniel Rossberg (Mar 14 2019 at 17:26):@Sagen Soren
Thank You for the helpful response, looking into the project options I am hugely influenced by https://github.com/opencax/GSoC/issues/27 . I needed a head start in working with the codebase, since I am working for the first time with a huge code base
Supposing you already master to build BRL-CAD from source code, I recommend to have a look at the QtGUI: https://sourceforge.net/p/brlcad/code/HEAD/tree/rt%5E3/trunk/src/QtGUI/
This was a project of second last GCi. It was programmed by high-school students in a few days and demonstrates how a Qt based GUI can be programmed on top of the C++ core interface. This program and the C++ interface are rather clear, and could be used as a starting point for own experiments.
To build this program you have to check out the rt^3 trunk branch side-by-side with the brlcad trunk.
Sagen Soren (Mar 20 2019 at 02:36):While using BRL-CAD I faced a problem. After a design when I am typing mged>rt it should have produced a 3D lighted solid model of the wireframe model. But instead the dialogue box opened, is full white and no solid model is shown. Can anyone help me out here by explaining why is this happening?
Sean (Mar 20 2019 at 02:42):@Sagen Soren screenshot? from the sound of it, you're simply in unfamiliar territory -- if it's white, you're probably looking at some geometry that is filling the window. If you run the "autoview" command, it will auto-resize based on what is drawn. If you run the "who" command, you'll see a list of what objects are drawn.
Sagen Soren (Mar 20 2019 at 02:49):Ohk. I will check it out.
Chetan Shinde (Mar 24 2019 at 13:53):Guys reporting a bug.
While exploring the doxygen module i came across this bug.
Link to the bug.
http://brlcad.org/docs/doxygen-r64112/files.xhtml
Sean (Mar 25 2019 at 04:42):@Chetan Shinde Thanks. Though I caution that the uploaded doxygen you're looking at there is r64112 ... and current sources are at r72738
Better to get an SVN checkout and browse the sources directly (and ask questions of course)
Daniel Rossberg (Apr 19 2019 at 13:37):To the students who are interested in the New BRL-CAD GUI project: This task is about writing a new graphical user interface from scratch. As reference for what we think at, there is a link to high-school students CAD GUI designs created during Google Code-in the project idea description text.
We recommend to use Qt for the GUI elements. If you want to use something different, you need a very good reason to do so, and need to convince us.
There is already a Qt GUI for BRL-CAD, which was created during a number of Google Code-in tasks by high-school students: src/QtGUI in the rt^3 repository branch. I recommend to have a look at this and use it as a template for your own ideas because it solves three issues already: Integration into the CMake build, establishing the connections to the Qt and BRL-CAD (here: C++ coreInterface) libraries.
Sadeep Darshana (Apr 24 2019 at 17:11):
I want to open (or create) a .g file and display it inside this(qt app i created) application and do a very basic thing like making a sphere.
Any advises on how I should start? @Daniel Rossberg @Sean
Sadeep Darshana (Apr 24 2019 at 17:46):how to add these features and build the basic scaffolding?
Daniel Rossberg (Apr 24 2019 at 19:22):Again, I recommend to have a look at the src/QtGUI program in the rt^3 sub-repository. This demonstrates how to do a Qt based GUI inside BRL-CAD's CMake build system, and how to connect to a BRL-CAD library, here the C++ core interface.
Daniel Rossberg (Apr 24 2019 at 19:26):With this C++ interface you can do very much everything you wrote about. For example, creating a new .g database can be done via opening a file-database with a yet not existing file or by saving an in-memory-database to a not yet existing file.
Sadeep Darshana (Apr 25 2019 at 07:48):Where can I find coreinterface ?
/usr/bin/ld: cannot find -lcoreinterface
building QtGUI
Sadeep Darshana (Apr 25 2019 at 07:49):@Daniel Rossberg
Daniel Rossberg (Apr 25 2019 at 13:40):You have to check-out the rt^3 subrepository. See https://brlcad.org/wiki/SVN. The module is rt^3. Therefore the SVN URL is https://svn.code.sourceforge.net/p/brlcad/code/rt^3/trunk.
Check it out into a directory (usually named rt^3) parallel to your BRL-CAD brlcad checkout.
Daniel Rossberg (Apr 25 2019 at 13:41):The coreinterface is included in the src directory there.
Sadeep Darshana (Apr 25 2019 at 16:56):i have already put main brlcad and rt^3 in place preserving the directory hierarchy in a (root dir in my computer being 'code')
Main brlcad is working properly. Also installed it as mentioned in http://svn.code.sourceforge.net/p/brlcad/code/rt%5e3/trunk/README
In rt^3,
cmake works fine
Only when I try to build it gives
"[ 22%] Linking CXX executable ../../bin/QtGUI
/usr/bin/ld: cannot find -lcoreinterface
collect2: error: ld returned 1 exit status" @Daniel Rossberg
Sadeep Darshana (Apr 25 2019 at 16:59):Linking with coreinterface is where it goes wrong
Sadeep Darshana (Apr 25 2019 at 18:33):I managed to fix this, QTGUI is running
Sadeep Darshana (Apr 25 2019 at 18:54):Within the GSoC period I'll be improving QtGui in rt^3 into a GUI that is fit to be shipped as a replacement to Archer and MGED, by adding the necessary features and giving it the look and feel of the Qt application I have already created (look screenshot in above the chat)
I am sending a proposal that will describe what I plan to do in detail, alone with the timeframe.
@Daniel Rossberg @Sean
Daniel Rossberg (Apr 25 2019 at 21:02):@Sadeep Darshana You can copy the QtGUI directory to, for example, MyGUI and include this in your CMake build to do your experiments.
Daniel Rossberg (May 01 2019 at 13:01):@Sadeep Darshana Please, read the comments for the methods in the header files. Object* BRLCAD::ConstDatabase::Get(const char* objectName) returns a copy of the objects. void BRLCAD::Database::Get(const char* objectName, ObjectCallback& callback) is intended for changing object properties.
How the process of creation, adjusting properties, and linking to a combination of an object can be implemented with the core interface can be seen here: https://brlcad.org/wiki/CoreInterface_Hallo_World_Example (on the example of a half space).
Forget the realtime rendering. Evaluating if this is even a theoretical option would be a GSoC project of its own. The closest one could do is to tessellate the model in triangle meshes and display them e.g. with OpenGL. The C++ interface provides the Facetize() method to get a triangulated boundary representation of the objects.
In addition, you could expect that the ray-trace provided by the C++ interface is the fastest available in the actual hardware and software environment.
Also, I wouldn't think about having a command window in the new GUI. @Sean may however have another opinion here.
The BRL-CAD command lines are in fact TCL shells, and TCL is a Moloch. One could argue that BRL-CAD users are used to the command line interface, but what else could they use to create the models?
Some commercial CAD programs provide a command line interface as well, but these are intended for plugins and automating tasks.
Sean (May 02 2019 at 17:30):There doesn't need to be a command window (or panel or similar dedicated space) with a new GUI. I think we will eventually want to expose libged commands in some form, but that can be trivially added later -- we have a couple applications already showing how easy that is. Definitely not something needed right away, but also not something we are going to abandon.
As a point of clarity, while BRL-CAD's command line is exposed via a Tcl shell in mged and archer, the two are not interlinked. You can issue commands without Tcl. One can easily expose BRL-CAD's commands via any interpreting environment like zsh, bash, python, lisp, perl, etc., or without a shell too, run a la carte (e.g., src/gools/gsh.cxx and src/gootls/gex.cpp).
Any command interface shouldn't be a substitute for good GUI design, which I think we all agree is the focus.
Sadeep Darshana (May 03 2019 at 19:34):I'll send a revised proposal today.
Something I have always been wondering is at which point I should work on integrating the wireframe graphical display instead of the rendering and refresh image thing that is there now.
Do you think implementing that earlier in the project can help with development, or can it be easily embedded later towards the end of the project?
Also does the Qt Display Manager take care of Mouse inputs? Or does it have to be implemented?
Sadeep Darshana (May 03 2019 at 19:40):Where can I find the code for Qt Display Manager?
Sean (May 04 2019 at 02:08):@Sadeep Darshana Look forward to seeing the update. I'd certainly encourage you to take a look at integrating the wireframe, just to not get too distracted with it just yet. The code is in src/libdm/dm-qt.cpp, enabled when Qt is detected and enabled during CMake. So you'll want to install Qt and make sure CMake finds it (and says so in the summary), which might take some tweaking or minor code updates.
So it's a double-edged sword -- IF you can get a (libdm) display manager integrated and working in a Qt GUI, you will get nearly instant access to (shaded) triangle mesh and wireframe drawing like you see in mged automatically. That said, the libdm code is typically hard code to comprehend and debug, so there's a learning curve and you very well might make faster progress doing something new using Qt3D, but then having to replicate some of the code in libdm for getting geometry representations. As Daniel mentioned, coreInterface has an API for getting triangles, though, so you could simply start with that if you like the clean slate approach. Start with libdm if you want the more featureful but harder approach.
For your proposal, I suggest you keep it as simple as possible, low risk, modular, so things can be updated/replaced if desired later, but always functional. For exploring the code and getting familiarized, I think you should check out as much as possible. ;)
Sean (May 04 2019 at 02:14):Be sure you're read http://brlcad.org/wiki/User:Vladbogolin/GSoC2013/Logs if you haven't, follow his links, read his code. Then there's the qtged branch which has a working hierarchical object view, which is pretty essential to graphical geometry navigation. No documentation, but you can reach the original developer @starseeker as needed if you have questions (he's also on IRC). Lastly, you could take a look at Ralith's 2008/2009 project -- http://brlcad.org/wiki/User:Ralith
Sean (May 04 2019 at 02:19):Ralith's project was a failure, but he got exceptional mouse navigation controls working with binding profiles implemented that matched MGED, Blender, and a standard Orbital camera.
In the best of all worlds, you'd be able to glue that all together with the Window and hierarchy from starseeker's qtged, the context from Vladbogolin's dm-qt, and Ralith's mouse controls on top of coreInterface and libged. Simple. ;)
Sadeep Darshana (May 04 2019 at 05:04):Enabled Qt in the main brlcad project and In MGED selected Modes->DisplayManager->Qt
The application crashed.
Daniel had told me this would lead the application to crash.
Sadeep Darshana (May 04 2019 at 05:19):Also I do not understand the need there was for a Qt Display Manager, since by the time Qt DM was implemented the OpenGl DM was already there and OpenGl is cross platform. Why was a Qt DM implemented?
Sean (May 04 2019 at 15:22):@Sadeep Darshana how you access OpenGL is not cross-platform. On Linux, one typically uses GLX, on Windows it's WGL, on MacOSX it can be GLX or Aqua, each being a different set of code to support them. With a Qt DM, there's just one code.
Sean (May 04 2019 at 15:25):Once you have an OpenGL context, you're right in that the OpenGL calls themselves are the same API, same code, but that's not what is being referred to here -- it's the creation and management of the drawing surface being used by OpenGL that is the issue and for that, there's the low-level methods (e.g. GLX and WGL) and higher-level methods (e.g., Qt3D, GLUT, GLFW, etc).
Sean (May 04 2019 at 15:26):we've had the low level interface since before OpenGL existed, but now we want to make it go through a higher-level interface: Qt3D ;)
Sadeep Darshana (May 04 2019 at 16:28):I understand. I assume dm-glx & dm-wgl are the corresponding src files for those platforms.
I'm trying to find the best way to design the toolbox (only primitive create tools)
1) RHC & RPC look different from Cylinders and Cones for an end user. Should we put them under a new category? (in case we are going for a design that categorizes). What about Elliptical Paraboloid being under ellipsoids?
2) Is starting A,B,Cs being at 2:1:1 the the only thing special about ell1 from its generic type ell ?
3) Regarding our discussion about wireframes/rendering.
Without implementing this it is impossible to implement any editing. (other than property changes through properties panel). Even position/rotation changing will have to be delayed. Anyway in the proposal I'm putting the wireframe thing and everything that depends on it towards the later weeks.
4) In dm-qt.cpp
Is the only reason tk and tcl stuff are in the code, because the whole rectangular graphics window is placed inside a Tk window?
Sean (May 05 2019 at 02:43):Thanks @Sadeep Darshana. Update received.
I understand. I assume dm-glx & dm-wgl are the corresponding src files for those platforms.
Yes.
I'm trying to find the best way to design the toolbox (only primitive create tools)
Lots of viable ways and feel free to argue otherwise, but I'd keep it familiar and simple -- Photoshop (PS) pretty much nailed this. Have a panel of tool icons. When one is selected, you're presented with its options (e.g, upper toolbar in PS).
That's pattern is inherently modular should we want to change appearance or behavior (e.g., swap out a tool for another or change displayed options) and maps to existing capabilities very directly.
1) RHC & RPC look different from Cylinders and Cones for an end user. Should we put them under a new category? (in case we are going for a design that categorizes). What about Elliptical Paraboloid being under ellipsoids?
Keep it simple. Wouldn't do anything to depict categories yet.
2) Is starting A,B,Cs being at 2:1:1 the the only thing special about ell1 from its generic type ell ?
No. If you know OOP, it's like a different C++ constructor for the same class. You'll see this directly if you run the "in" command. It will prompt you for each parameter based on the type of object you try to make.
ELL is created via three vectors. ELL1 is created with 1 vector and a radius. Both result in an ELL object, only difference is how they were created.
What this does raise is there possibly needing to be some way to have alternative ways for specifying parameters later, but it's out of scope for you.
3) Regarding our discussion about wireframes/rendering.
Without implementing this it is impossible to implement any editing. (other than property changes through properties panel). Even position/rotation changing will have to be delayed. Anyway in the proposal I'm putting the wireframe thing and everything that depends on it towards the later weeks.
Having some visual representation of geometry is kind of central to a GUI, more important than editing. It's okay to defer or have a placeholder for "draw geometry here" at first, but once there are buttons and panels that will quickly be a necessity to ensure everything is getting wired up correctly.
4) In dm-qt.cpp
Is the only reason tk and tcl stuff are in the code, because the whole rectangular graphics window is placed inside a Tk window?
Yes. As it is a Tk window, Tk also handles that window's key and mouse events. In a pure Qt context, that is all bypassed (qt_open_existing()).
By the way, check out http://brlcad.org/design/gui/ if you haven't already. Particularly like Alexander's work. Folder has lots of big-picture concepts and examples of other CAD GUIs (good and bad).
Sean (May 05 2019 at 03:02):This is a particular bit of inspiration I just wanted to share, only remotely relevant as it's not a CAD GUI but is one of the most astounding examples of massive and localized option management: NoWindows.png
You can think of the upper tabs as being tools (e.g., "Text" is a tool). The options for that tab display when the tool's icon is selected. Of course, tabs as tools won't work if there are lots of tools, but the notion is the same even if you put all those tab icons into a panel on the left and leave the options at the top (which is essentially what PS does).
Sean (May 05 2019 at 04:00):While I'm at it, might as well show one of the newest CAD GUIs that is taking off big in popularity, from OnShape: e9ab5754-af10-4c2d-8936-afc487499881.png
Sadeep Darshana (May 05 2019 at 07:31):(deleted)
Sadeep Darshana (May 05 2019 at 07:33):Proposal here refers to "BRL-CAD Proposal V3.pdf" I send via email seven hours ago.

but the notion is the same even if you put all those tab icons into a panel on the left and leave the options at the top
Please find the the last paragraph and the sentence before the last paragraph in 3.2.1. I have described the problem with this approach.
To proceed with this approach we have to change the event on which object is created to some mouse event on the graphics window (from mouse click on the toolbar icon now).
Having some visual representation of geometry is kind of central to a GUI, more important than editing. It's okay to defer or have a placeholder for "draw geometry here" at first
We already have a way implemented in QtGui to display the geometry. It raytraces and updates the image.

This is sufficient for viewing in development.
Sadeep Darshana (May 06 2019 at 19:27):How do I get the Qt DM running on mged without the application being crashed. Daniel told some special settings have to be made for Tcl/tk. I'm trying to embed the qt dm before the coding period officially begins.

(I enabled qt, now the menu item shows, but crash when selected)
I debugged a bit and found the following in the Qt documentation of QApplication::QApplication(int &argc, char **argv):
Warning: The data referred to by argc and argv must stay valid for the entire lifetime of the QApplication object. In addition, argc must be greater than zero and argv must contain at least one valid character string.
And now you ;)
Daniel Rossberg (May 07 2019 at 18:03):While it's good to know the Qt display manager (and with the above hint you should be able to fix its crash), the project aims for a new GUI with a new concept for user interactions (which means new for BRL-CAD). This is a step-wise process.
The first step would be to find a name for the new GUI. You need it as directory name for your source code, for example. You could throw some possible names here and ask for comments.
Inder Singh (May 11 2019 at 08:48):Hi @Sadeep Darshana I am co-mentor for "New UI for BRL-CAD" project. Congratulations for getting selected in GSoC 2019. I will try to help you with the design side of things and do my best to make this summer of code a successful experience for us.

Integrating the DM seems a little hard I'm trying to do the basic UI stuff first. There are several aspects I talked about when it comes to the design of UI toolbars etc. Also Sean did suggest ways. Which way do you think I should choose?

We are looking for a new user interface with a look and feel similar to the "usual" CADs. For the start, you may want to take one or two designs from the GCi tasks or compile an own as template, and implement it in Qt. (Please share your choice with us before you start implementing it.)
When you implement it, you shouldn't try to trick Qt but use its widgets as intended. Furthermore, connecting the GUI with the BRL-CAD functions has no priority when you implement your first design.
Daniel Rossberg (May 16 2019 at 15:05):@Sadeep Darshana Even if you don't use the current display managers for the new GUI (which is OK because we want a different "user experience" there), you should consider to provide a patch for the bug which prevents the current Qt display manager from working. See my considerations in https://brlcad.zulipchat.com/#narrow/stream/111975-Google-Summer.20of.20Code/topic/New.20BRL-CAD.20GUI/near/165052853. It's a Qt issue, which taught me something about Qt.
Inder Singh (May 17 2019 at 17:54):@Sadeep Darshana are you writing a daily diary? If yes, can you please give me the link here? If not, it's a good idea to set it up before the coding period begins.

I'm studying on this. I really appreciate if you could guide me on what I should look into.

Sadeep Darshana (May 25 2019 at 21:26):Please ignore above question
Displaying geometry seems to be difficult. A lot of files are involved. Without all this complexity, is there a way to display a database in a Qt component in a simple way only for the development purposes. (it's better content being displayed when I'm working on other UI related things)
Daniel Rossberg (May 26 2019 at 16:32):Do you know what steps are necessary to create a GUI which can create and edit objects?
I'm studying on this. I really appreciate if you could guide me on what I should look into.
OK, I'll first explain what it's not, exemplified by the sphere: Click the create sphere icon, then a dialog opens where you have to type in the name, center, and radius, and at the end you hit the OK button.
What's wrong with it? The GUI doesn't support the creation of the sphere! You could do the same with mged in nu mode, maybe even faster, because you don't have to change between keyboard and mouse. From a CAD GUI you can expect that it helps you to determine the center and radius (and the name) of the sphere. For example, to do the goblet in the tutorial you want to place the spheres for the stem by clicking on the places where you want to create them on the screen.
Which are the steps one had to do for this? I recommend to go this way:
* Creation of a mock-up GUI: It shows the intended layout and functioning, but it isn't connected to any BRL-CAD core function yet.
* Opening, saving, and closing of BRL-CAD database files: Here starts the connection with BRL-CAD functions. It should be easy to implement, but already arise a question about the GUIs behavior.
* Displaying the geometry on the screen: This is one of the big points, which requires some work. I'm thinking at a wire-frame depiction here. The lines could be taken from the tessellation or the plot functions (I would prefer the plot functions). Did you thought of having GUI elements for shifting, rotating, and zooming the view in the first step?
* Determining model points under screen points: When the user clicks on the screen, which point does they mean?
* Creation of a sphere: After having all the above done, this shouldn't be so complicated any more.
* A preview of the sphere during its creation: When the center of the new sphere is determined, a circle which moves with the mouse should help the user to imagine how this new sphere looks like with the other geometric elements.
Well, if you are able to create a sphere with your GUI at the end of GSoC you are good :wink:
Sadeep Darshana (May 26 2019 at 20:37):Thank you @Daniel Rossberg . It was really helpful and clarifies a lot of doubts. This sort of reaffirms what I had in my mind.
But I'm sorry I misunderstood this.
Do you know what steps are necessary to create a GUI which can create and edit objects?
What I really wanted to know was how do I create the GUI that displays/edits the geometry? (THE GRAPHICS WINDOW)
I looked at the sources to understand the process but it is too hard to understand without help.
For instance when I look at the mged there are a lot of source files involved. The DMs, mged_dm.h, the tcl scripts, dm-generic.
1. Can someone give me a brief idea about in which source file each stage related to displaying geometry on screen happens?
I want to get the abstract idea of how DisplayManagers, OpenGl, Tk(in mged/archer), and anything else related connects and what they do.
For example, what decides the positions of the lines displayed for a sphere, what decides the pixels needed to color to draw it on screen. What draws it on screen. Which widget(ex:togl) in Tk has been used to display geometry
2. Any tips on how I might create this on Qt?
I want to get the geometry displayed on the screen as soon as possible since all the development depends on it.
@Sean @pooh (inder) @Daniel Rossberg
Daniel Rossberg (May 27 2019 at 15:52):How to display the geometry in the GUI? That's easy: With a QWidget! It is as trivial as it sounds. Look for example at rt^3/src/QtGUI/GraphicView.
Well, for a real nice CAD display there is something more to do, but this is the start.
To understand the mged display managers you might want to have a look at the null dm (brlcad/src/libdm/dm_Null.*). There you see that the display managers are mainly different implementations of functions declared in the struct dm_internal. This are functions for draw management, setting the transformation matrix, setting the color, drawing simple objects, handling display lists, etc.. And all this can be done in a X Window, OpenGL window, QWidget, etc., depending on which implementation of these functions you use.
Sadeep Darshana (May 27 2019 at 17:37):i had studied the displaying in QtGUI. It simply raytraces the objects everytime something happens and draws the output image in the QWidget. I believe this would be more troublesome
Daniel Rossberg (May 27 2019 at 17:42):Not necessarily. You get out a wire-frame description from the model and draw it with the corresponding Qt functions.
Sadeep Darshana (May 27 2019 at 17:47):so for this I can use the dm-qt?
Daniel Rossberg (May 27 2019 at 17:58):so for this I can use the dm-qt?
NO. You don't work on mged or archer but on a new GUI with new behavior.
Daniel Rossberg (May 27 2019 at 18:11):The point with the mged display manager is, that it should give you an idea what's expected from the graphic engine, and it can be implemented with Qt or OpenGL. But, we don't expect you to copy them to the new GUI.
Sadeep Darshana (May 29 2019 at 22:18):why does dm-tk use Xlib?
Sadeep Darshana (May 30 2019 at 00:10):I believe a DM based on OpenGL should be implemented for this since Display Managers based on window systems like Tk or Qt use a 2D plane and we have to do the converting. In opengl we are dealing with a 3D environment. This is better especially when we want to display objects other than wireframes. Also we are given the abstraction of a 3D environment with a lot of other features like lighting which are not available if we used a Window System based DM. People might not want to work with wireframes since almost all other CAD software display solid
In Qt the way to implement an open gl based DM would be to use QOpenGLWidget and implement new-dm_drawVList function to draw on that widget. I believe this function would be almost identical to osgl_drawVList, ogl_drawVListor wgl_drawVList
@Daniel Rossberg @pooh (inder) @Sean
Sadeep Darshana (May 30 2019 at 00:22):I do understand how the Vlist is displayed on the screen by different DMs. Now I need to look at how Vlists are created from the db. I will start implementing hopefully tomorrow.
Sadeep Darshana (May 30 2019 at 00:39):Why are display lists used?
Daniel Rossberg (May 30 2019 at 15:46):why does dm-tk use Xlib?
Because the Tk graphics window uses X Window features? The would mean that it works with a X Window environment only, of course. You can find it out by either looking for xlib functions in the code or removing the xlib includes and see what is broken after that.
Daniel Rossberg (May 30 2019 at 15:52):I do understand how the Vlist is displayed on the screen by different DMs. Now I need to look at how Vlists are created from the db.
ft_plot() (the rt_~_plot() functions)
I will start implementing hopefully tomorrow.
Do the mock-up first.

I'm afraid this isn't a good idea. My doubts start with your argumentation with the "2D Qt plane" and 3D OpenGL environment". Maybe, you don't know what OpenGL does: Computing 2D raster images from 3D input data. I.e., you need to consider the 2D display plane there as well. What complicates it is, that you need to translate the BRL-CAD transformation an display logic into the OpenGL "language". This isn't trivial, see the annotation bug thread here for example.
If you know what you are doing and how to say it in OpenGL, it can be a powerful tool to accelerate the graphic routines, because a good OpenGL driver will do many of the computations on the graphic card.
Lightning, textures, etc. are another issue, were OpenGL is hard to use, because BRL-CAD has its own renderer with algorithmic generated textures, for example. Shifting this to the graphic card is far behind the scope of your project (and would probably be hidden behind the BRL-CAD interface).
BTW, people are forced to work with wire-frames, because solids cover what's behind them ;)
Daniel Rossberg (May 30 2019 at 16:34):Why are display lists used?
:grinning: Therefore: Whats's a display list? As already mentioned, graphic libraries as OpenGL take their power from shifting a large part of the computational work to the video card. To be effective, as much data as possible hast to be stored there too. You may have heard that there is memory for textures on a video card. The display lists are chunks of the model or CAD data, reduced to simple primitives (often triangles), which can be stored on the video card and used there without bothering the CPU or RAM again.
For example, for the wire-frame view, you could put all the edges from the BRL-CAD model in a huge edge list as a display list, and store it on the video card. If you zoom, shift, or rotate the view now, you have to readjust the camera only and send the command for redrawing the stored display list.
Inder Singh (May 30 2019 at 19:09):Hey @Sadeep Darshana were you able to create a daily dev log somewhere? If so, can you please share the link with me?
Inder Singh (May 30 2019 at 19:10):I am getting a gist of what you do daily from this zulip chat. It's just that all of that progress written in your own words at one place will help you and me see the trajectory and velocity of the progress. :)
Sadeep Darshana (May 31 2019 at 20:26):I did update the progress. Exams and the academic timetables (were supposed to over now) have been delayed due to reasons I could not predict when I applied. So I'm struggling to allocate as much time on this as possible.
@Sean @pooh (inder)
Some questions I have been having
1) Doesn't rt in librt stand for RayTrace? If so why are things like db open and vlist generation in it?
2) 'RT^3' what does this mean?
3) Was coreinterfaces and qt gui developed as parts of the same project?
Sean (May 31 2019 at 20:50):I did update the progress.
Thank you. The information looks good, but try to keep things separated with an entry per day going forward, not ranges of days.
Exams and the academic timetables (were supposed to over now) have been delayed due to reasons I could not predict when I applied. So I'm struggling to allocate as much time on this as possible.
This is understandable and will certainly be a challenge for you. In particular, it's going to be a time management challenge until at least the 17th. I suggest you dedicate some part of your day at a specific schedule, like 4 hours a day from 9am-11am and 6-8pm 4-5 days a week, something like that instead of trying to burst a whole 8-10 hours one day and then nothing for 2-3 days because you're now behind on studying for some exam. If we see you making even a little bit of activity and actual progress every day, that will be reassuring. Then you can adjust your schedule after exams are over to make up lost time (e.g., 50-60 hour weeks for 3-4 weeks). What doesn't work and gets you on a trouble radar is when you do nothing for 3+ days.
1) Doesn't rt in librt stand for RayTrace? If so why are things like db open and vlist generation in it?
It does stand for ray tracing. Originally the database functions were actually colocated in librt for low-level performance reasons. Those reasons, however, no longer matter so there are plans to extract them into their own "libg" for the .g file format. As for vlist generation, that's a property of objects, which also belongs to the individual primitives (they must describe themselves in a wireframe form, in textual form, in raytrace form, etc).
2) 'RT^3' what does this mean?
"RT cubed" is simply the name of the repository holding some "next generation" plans for BRL-CAD. In mathematical terms, to cube something is to multiply it three times (e.g., 8^3 = 8 * 8 * 8 = 512). Other than a fun mathematical project name, it has no other implication.
3) Was coreinterfaces and qt gui developed as parts of the same project?
They were developed independently but added to the rt^3 repository as that's where "next generation" code projects have been worked on.
Sadeep Darshana (May 31 2019 at 22:01):What is the square root of 50 + 14?
Sadeep Darshana (May 31 2019 at 22:01):or 100 - 51
Sadeep Darshana (May 31 2019 at 22:02):it's broken apparently
Sadeep Darshana (May 31 2019 at 22:23):I obtained vlist for 1 object in RT^3, QtGui project. using ft_plot. Thanks @Daniel Rossberg for pointing in this direction. Was a big time saver. My next task is to display wireframe in a widget in qt.
1. For this I need to study, Camera angle and distance setup like things. And other things that might be needed for rendering a wireframe scene.
2. Also I noticed something called ft_adaptive_plot. some optimizing thing?
3. Will I be needing displaylists or can I straight away display wireframes. (i.e. is it essential or just an optimize thing)
@Daniel Rossberg @Sean
Sadeep Darshana (May 31 2019 at 22:29):Hey Sadeep Darshana were you able to create a daily dev log somewhere? If so, can you please share the link with me?
@pooh (inder) http://brlcad.org/wiki/User:Sadeep/DevLog-NewGui. I could not update the log today. because What is the square root of 1000 - 100?

pooh (inder) http://brlcad.org/wiki/User:Sadeep/DevLog-NewGui. I could not update the log today. because What is the square root of 1000 - 100?
Perfect! Thank you so much. I would just advice to add at-least single line at end of every day, like even if you didn't work on anything just say it. I remember Sean saying me when I was a student "If you spent the day on the beach, just write it down" :D (something along that line, not exact words)
Sadeep Darshana (Jun 01 2019 at 05:05):I cannot edit a brlcad wiki page (my dev log) from my laptop (ubuntu, chrome). It says "Error: Incorrect or missing CAPTCHA." every time.Apparently it works on mobile. Anyone experienced similar issues?
Sean (Jun 01 2019 at 05:10):What is the square root of 50 + 14?
what do you think the answer is? the captcha is working for me
Sadeep Darshana (Jun 01 2019 at 05:11):8?
Sadeep Darshana (Jun 01 2019 at 05:11):(without the question mark)
Sean (Jun 01 2019 at 05:12):yes, so if you entered that and it didn't work, something is awry but hard to say what's wrong. are you hitting enter or clicking the submit button?
Sean (Jun 01 2019 at 05:13):if you log in, it will not prompt the captcha
Sadeep Darshana (Jun 01 2019 at 05:16):Something wrong with the cookies it seems. Says

when I try to login. Works well on incognito mode
Sean (Jun 01 2019 at 05:18):perhaps try deleting your cookies for brlcad.org?
Sadeep Darshana (Jun 01 2019 at 05:20):Didn't work. Maybe user of the default header sent from the normal mode suspected as trying to hijack or something. Doesn't matter I can manage this with incognito mode or mobile. Thanks
Sean (Jun 01 2019 at 05:29):are you unable to log in?
Sadeep Darshana (Jun 01 2019 at 06:18):I can log in using firefox
Sadeep Darshana (Jun 01 2019 at 19:59):I'm implementing displaying in both QOpenGLWidget using OpenGLand QWidget using window system functions. Working on the OpenGL method today.
Sadeep Darshana (Jun 01 2019 at 21:36):Added QOpenGLWidget to the application. Line creation is not straight-forward like in the earlier OpenGL version which existing OpenGL DMs use in BRL-CAD. glBegin and glEnd are have been deprecated and now removed. Studying the new method. This means I will have to change the code in the existing vlist_draw functions to suit the modern opengl.
Sean (Jun 01 2019 at 22:08):They're not removed yet, and won't likely be removed anytime soon. So using new or old OpenGL should be fine. That said, the new is better but I wouldn't get too caught up on the details other than what you need to do basic drawing of lines and/or triangles.
Sadeep Darshana (Jun 02 2019 at 06:51):I'm using the legacy component QGLWidget (old opengl) instead of QOpenGLWidget (no glbegin) since it will be easy to use and the main emphasis of the project should be on creating the application UI than the display manager
Sadeep Darshana (Jun 02 2019 at 14:21):bu_lists are very weird. Iterations crashes when iterating inside GraphicsViewOpenGL::paintGL() method. Iterating works well when used inside methods I define. Does it have anything that could cause unexpected behaviors? like threading?
Sadeep Darshana (Jun 02 2019 at 16:03):IGNORE THE ABOVE MESSAGE !! IGNORE THE ABOVE MESSAGE !! IGNORE THE ABOVE MESSAGE !!!
Got this solved after struggling few hours.
C++ erases local variable objects even though you set a global level reference to point that after declaring it. Java is a lot easier.
Sadeep Darshana (Jun 02 2019 at 21:11):pasted image
Wireframe displaying implemented to display wireframes of 2 objects that I name in the scene.
Sadeep Darshana (Jun 02 2019 at 21:17):intern.idb_meth->ft_plot(&vhead,&intern,m_wdbp->wdb_initial_tree_state.ts_ttol,m_wdbp->wdb_initial_tree_state.ts_tol,&info);
This crashes when plotting combinations. Any idea why?
Sadeep Darshana (Jun 02 2019 at 21:18):Is it not possible to plot combinations using ft_plot?
Sadeep Darshana (Jun 02 2019 at 21:21):pasted image
Would be great if we can have these. Will this be hard to implement with openGL?
Sean (Jun 03 2019 at 11:57):intern.idb_meth->ft_plot(&vhead,&intern,m_wdbp->wdb_initial_tree_state.ts_ttol,m_wdbp->wdb_initial_tree_state.ts_tol,&info);
This crashes when plotting combinations. Any idea why?
Do you know how to use a debugger like GDB or LLDB? If not, this would be a great time to do a little tutorial from the web. Basically, you can run as you usually do, and then when it crashes, you can examine the backtrace which will tell you exactly where it crashed and what the variables were at that time.
If you did in this instance, you'd find that intern.idb_meth->ft_plot is NULL, and that's why it crashes.
Sean (Jun 03 2019 at 12:01):So you're right in that you can't currently plot combinations using ft_plot() -- they don't know how to plot themselves (see src/librt/primitives/table.cpp for all callbacks and src/librt/comb for implementation). The logic for how combinations get plotted is quite complex for mged and archer, and it's not yet been cleaned up enough to be a simple callback. You can see the combination plotting logic in src/libged/draw.c
Sean (Jun 03 2019 at 23:47):@Sadeep Darshana That all said, I'm a little surprised you're working with low-level OpenGL code and directly calling into librt for plot lists. What is your first project milestone? If it doesn't entail OpenGL, then you will want to refocus on the milestone -- there's not much time in your schedule for distraction (like implementing those coordinate axes). As the plan is for the gui to go through coreInterface, you should be getting plot information from it instead of via ft_plot() too.
Sean (Jun 03 2019 at 23:53):Reading your project plan, looks like the first milestone is opening and closing a geometry database -- if you can do that already, you should have submitted code for review. If you have not, that is what you should be working on now. :)

@Sean
1. How do I obtain plot list through CoreInterfaces? Is a function that does the functionality of ft_plot() already implemented in CoreInterfaces?
2. DM had to be implemented because without it I won't be able to develop other required things like creating a sphere on the canvas with the mouse. Or editing. Btw I won't be focusing on those coordinate axes (they are object rotate/scale/translate handlers) or will do them at the end if time permits.

Sean

You can use the database Facetize() method to get a triangle mesh boundary representation of the geometry. The edges of these triangles create a wireframe.
There will be likely be a plot-like method in future, but all you need for the beginning is a set of edges, which you can obtain via Facetize().
2. DM had to be implemented because without it I won't be able to develop other required things like creating a sphere on the canvas with the mouse. Or editing. Btw I won't be focusing on those coordinate axes (they are object rotate/scale/translate handlers) or will do them at the end if time permits.
You can't have a DM without a window, which you don't have. You still work with the QtGUI from GCi, which is far away from what we expect a CAD GUI should look. We clarified the priorities for your project here, but you haven't started with the first of them yet.
Daniel Rossberg (Jun 04 2019 at 16:15):Metaphorically speaking, you are talking about the mountains you are seeing at the horizon, but you haven't start going there. Then, you have heard that a cable car is a good way to go up a hill, but you have no idea what it means to build one. You'll have to climb up the mountain first and find a path.
We, the mentors, can guide you there. This has to be done however step by step. It isn't useful to philosophize about things which look a bit different when you are standing in front of them, then you might think now.
Daniel Rossberg (Jun 04 2019 at 16:23):The creation of a complete functional CAD GUI is far behind the scope of your project. You should feel more like an explorer, who tries to come as close as possible to the desired software in the short time of this GSoC. You'll find many things which are missing or having a to bad (time)cost-benefit ratio to be done here. That's OK. This should be noted for the future.
Sadeep Darshana (Jun 04 2019 at 16:47):Okay, I'll work on the UI next
Inder Singh (Jun 08 2019 at 15:22):Hi @Sadeep Darshana I see that you have not updated your dev log from couple of days, is everything fine? Do you need any help?
Sadeep Darshana (Jun 09 2019 at 07:56):I did not do anything significant during the period. My exams are not over yet. I will do my best to find time to work on this.
Daniel Rossberg (Jun 09 2019 at 14:49):I did not do anything significant during the period. My exams are not over yet. I will do my best to find time to work on this.
Hmm, that's bad.
Inder Singh (Jun 09 2019 at 19:14):@Sadeep Darshana It would really help you and your mentors if you keep the communication running. So even on days when you havent done anything significant, inform us (through dev log and otherwise) about any non-significant thing you did, or even when you didnt do anything at all. Not communicating in my humble opinion is always worse than not working. I know its hard, I used to miss my dev log too, but I promise you this habit of daily updating will help you in successful completion of GSoC as well as in your future endeavors as a professional in tech industry.
Sadeep Darshana (Jun 09 2019 at 21:59):thanks @pooh (inder)
I didn't start working on the UI yet. When I start should I make improvements to the QtGui project or start it fresh?
Sean (Jun 10 2019 at 14:43):@Sadeep Darshana I will be sending an e-mail regarding your dev log. While you did let us know about your exams (through the 17th right?), I believe I also reiterated the importance of time management and still making some progress. Going 6 days without activity is not acceptable even with exams.
Sadeep Darshana (Jun 13 2019 at 19:35):I have done some improvements on the QtGUI
Is it prefered to start a new project or do things on top of the rt^3 QtGUI project?
@Daniel Rossberg
Sadeep Darshana (Jun 13 2019 at 19:36):@Sean
Daniel Rossberg (Jun 13 2019 at 19:55):Create a new project parallel to QtGUI.
Sean (Jun 19 2019 at 12:57):I'm fine with either approach, merits to both, downsides to both. ;)
Sadeep Darshana (Jun 22 2019 at 19:01):@Sean @Daniel Rossberg @pooh (inder) I hope you received my email. I'm implementing the toolbar.

Give me 30 mins @Sean
Sadeep Darshana (Jun 28 2019 at 04:02):@Sean @Daniel Rossberg @pooh (inder)
Here is everything you can do with the application I have created so far,
Open a DB
move around with the keys (has to be improved, also mouse support to drag/zoom viewport needed)
Create a sphere using the sphere tool (this has to be improved to support drawing with mouse)
save the database
the UI is far from what will be created ultimately, a lot of features when creating geometry also have to be pre set. also I will talk to the mentors and finalize on the positioning of components
Please have a look at the demo video,

Daniel Rossberg (May 05 2020 at 13:54):The current BRL-CAD trunk may be a bit bumpy. Revision 75083 works for me with Visual Studio 2019.
Sadeep Darshana (May 05 2020 at 14:07):Could be the case. It gave an error msg saying some -Ot build option was invalid. I will try out that revision
Sean (May 05 2020 at 17:49):Can include actual cmake or build output (can attach a log or paste code snippet in between two ~~~ lines), easier than guessing the context of an error, often helpful.
Sadeep Darshana (May 15 2020 at 18:16):What should I focus on implementing in the beginning?
Sadeep Darshana (May 15 2020 at 18:17):@Sean I hope my patch is also sufficient
Sadeep Darshana (May 15 2020 at 18:18):I am reusing the display manager I implemented last year. That would be sufficient for developing the UI for the moment.
Sean (May 15 2020 at 19:54):@Sadeep Darshana I haven't looked into the code yet, but the feature your patch implements looks fantastic! and you did that so quickly!
Sean (May 15 2020 at 19:57):As for where to start, this is a complex issue of prioritization and you're going to get different priorities depending on who you ask and what the near-term goal is.
Sean (May 15 2020 at 19:57):what would you like to do first?
Sadeep Darshana (May 16 2020 at 06:19):I want to build the most basic editor, yet functional
Sean (May 16 2020 at 21:04):@Sadeep Darshana you need to be way more specific. that could be almost anything. it also doesn't imply what the GUI itself will require.
Daniel Rossberg (May 18 2020 at 17:11):Sadeep Darshana said:

Did you tested it with the current BRL-CAD trunk revision?
Inder Singh (May 20 2020 at 03:56):Hey @Sadeep Darshana
How are you doing? I just wanted to check-in and understand how you are approaching the flow for new GUI. I would love to help you, especially on the UI part of things. Let me know if you need anything.
Sadeep Darshana (May 21 2020 at 17:38):@Daniel Rossberg it is working with the current version
Sadeep Darshana (May 21 2020 at 17:44):@pooh (Inderpreet Singh) It's great to hear from you. There are several Google Code In designs that I looked into. Also the UI of vectary.com seems interesting. I'm using CMake instead of qt's qmake to be consistent.
Daniel Rossberg (May 22 2020 at 06:30):OK. Next, you should remove all in the build process generated files from the repository, e.g. the moc_ files.
Inder Singh (May 26 2020 at 14:36):@Sadeep Darshana Awesome, it would still make sense to have a wireframe which is based on our favorite UIs (from gci, vectary etc). I wont block you with this wireframe task right now, as its more important for us to get properly set up and make some progress on the core coding side. So keep doing what you are already doing but soon enough we should consolidate our UI ideas. :innocent: So excited to see your progress.
Sadeep Darshana (Jun 01 2020 at 19:06):I started a new repository. Implemented basic save/open functions. Integrated the DM from my previous years works.
I accessed rt_i* m_rtip and resource* m_resp from ConstDatabase.h and rt_wdb* m_wdbp from Database.h (which are not public without changing coreinterfaces code) for rendering.
Daniel Rossberg (Jun 02 2020 at 11:50):@Sadeep Darshana Nice to hear that you started working. Where can I find your new repository? What do you plan for the next days?
Sadeep Darshana (Jun 04 2020 at 12:06):I added everything I did for the last few days to this repository. https://github.com/sadeepdarshana/arbalest
Will be pushing daily to this repo.

2) Adding drawable items toolbar to the UI. (support drawing 1 or 2 object types)
3) Implement adding new objects to a MemoryDatabase (to be used with drawing toolbar). (support drawing 1 or 2 object types)
I hope to complete these tasks within today and tomorrow. Anything else I should be focusing on?
Daniel Rossberg (Jun 04 2020 at 12:29):Hi @Sadeep Darshana, thanks for the link to your code. You chose an interesting name for your program :)
You can find code for generating a tree view of the database objects here: https://github.com/drossberg/BrlCadGUI/blob/master/src/MainWindow.cpp#L179
Would this vlist interfacing class help for the graphics output?
Sadeep Darshana (Jun 04 2020 at 12:49):@Daniel Rossberg This will likely help. I can make use of this and change my display manager not to use vlist directly. From my last year's experience I think I dived too much into the rendering part and lost focusing on the UI (which is the core goal of the project. (is it?)). So what I thought was to use last years code for rendering and make improvements to it only after focusing on UI (since we already can display stuff in screen).
Sadeep Darshana (Jun 04 2020 at 12:50):What do you suggest?
Daniel Rossberg (Jun 04 2020 at 12:56):Sadeep Darshana said:

I'm fine with your focus on the user-interface part. This should indeed be the main emphasis of your work. However, you'll gain profit from your last years rendering implementation.

I'll backport the VectorList class to the rt^3 repository then.
Daniel Rossberg (Jun 04 2020 at 15:50):Done.
It compiles with Linux, will test on Windows tomorrow. If it works, I don't know. We'll see.
Sadeep Darshana (Jun 04 2020 at 17:25):great
Sadeep Darshana (Jun 04 2020 at 17:29):is the code available in the latest revision of rt^3?
Daniel Rossberg (Jun 05 2020 at 06:36):Yes, with revision 76022.
Daniel Rossberg (Jun 05 2020 at 06:38):The Windows build seems to have an issue with the inline constructors of DLL-exported classes. It builds, but complains about them. I don't know how serious it is.
Sean (Jun 05 2020 at 07:17):It could result in version incompatibility if, for example, a DLL were updated but not the application. Code in the application would likely call the inline'd version whereas other libraries Dll-importing the symbol would get the different updated version. This could result in badness, but not a major concern nor is it likely.
Daniel Rossberg (Jun 05 2020 at 10:53):The warnings were abut a member variable of Vector3D type, which is not exported by the DLL. The declaration is fully inline. It looks like the compiler is "worried" that the declaration is different inside and outside the DLL, like it can happen with STL.
Maybe, having not inline constructors will make MSVC happy.
Sadeep Darshana (Jun 05 2020 at 11:36):@Daniel Rossberg I'll use this in the DM. thanks
Daniel Rossberg (Jun 05 2020 at 15:08):I investigated the build warnings a bit more, and decided to not touch them for the moment. It looks like suppressing them would be the best I could do in my case (https://www.cnblogs.com/zhangyz/articles/6238841.html).
The warning is about classes which have non-inline (i.e. real) member functions, which could probably not be present on the client's side. However, Vector3D is a very primitive class with only simple pure inline functions.
Sadeep Darshana (Jun 05 2020 at 20:30):I implemented creating new geometry and adding to db. (create sphere only with hardcoded parameters, no ui toolbar). Will look at this vlist thing next @Daniel Rossberg
Sadeep Darshana (Jun 06 2020 at 17:29):Qt's using thisCase for method names. Core interfaces is using ThisCase. I only noticed the difference now. So far the code I did follow Qt's convention. Should I switch?
Daniel Rossberg (Jun 07 2020 at 13:57):You don't need to switch.
BTW, having the same naming conventions as somebody else's library, which you use in your own code, can make it hard to distinguish between yours and alien types, functions, etc.. This depends on the definition of "own" and "alien" too.

If you call it explicitly a sphere I recommend to use the Sphere class. There is a primitive with ID_SPH (src/librt/primitives/sph).

Daniel Rossberg (Jun 10 2020 at 16:57):@Sadeep Darshana How is your progress?
You should commit to your Github repository at least once each working day. And your development log needs an update as well.
Sadeep Darshana (Jun 10 2020 at 18:42):Will commit the changes and give update the log. I was working on DM. Here is what I did.
Moving forward /backward (camera looking direction) with mouse wheel.
Configured so that cursor jumps to the other edge when it passes the boundary of opengl display while doing 1. or 2.
Grid lines
I had to spend some time to learn the stuff needed to implement the Camera and did a lot of experimenting to come up with the final solution. Studied representing rotation, creating modelview/projection matrices and using them to render the scene.
Sadeep Darshana (Jun 10 2020 at 18:44):The working code contains a lot of stuff I added to debug since the Camera is still WIP. So I did not commit. Will update the log.

Daniel Rossberg said:
It is possible to create a list of copies from the elements, but I decided no not explicitly support it (e.g. by providing a Clone() method), because this is not how this list should be used. It would slow down the process. Instead, you should move the corresponding drawing functions to a call-back class:
class ElementOpenGL : public BRLCAD::VectorList::ConstElementCallback { public: virtual bool operator()(const Element* element) { switch (element->Type()) { case BRLCAD::VectorList::Element::PointDraw: BRLCAD::VectorList::PointDraw* pointDraw = static_cast<BRLCAD::VectorList::PointDraw*>(element); // put your OpenGL code here break; case BRLCAD::VectorList::Element::PointSize: BRLCAD::VectorList::PointSize* pointSize = static_cast<BRLCAD::VectorList::PointSize*>(element); // put your OpenGL code here break; // ... } } }; void DrawVectorList(const VectorList& vectorList) { ElementOpenGL elementOpenGL; vectorList.Iterate(elementOpenGL); }This code demonstrates the principle only. It doesn't contain all necessary methods, checks, etc..
But @Daniel Rossberg , would this not slow things down instead of making things faster?
I had actually considered doing this but then decided against it due to the following reason. Think of the 2 scenarios.
Case 1 - We call opengl methods inside Iterate()
Each time the opengl scene is redrawn we need to call Iterate. In each call all elements in m_vlist are used to build C++ class instances. A single call to Iterate costs approximately the time taken to clone a list (if implemented) that contains all the Elements.
Each time the geometry is changed we need to call Plot. In this call m_vlist is built.
Total cost in a session = (# OpenGL redraws * costs for Iterate) + (# geometry edits * cost for Plot)
Case 2 - We generate and save the list of all elements when Plot is called and keep using that same list for drawing until geometry is changed again.
Total cost in a session = # geometry edits * (cost for Plot + costs for Iterate+ cost to clone the list)
Cost to clone the list can be avoided if supported by coreinterfaces (e.g allocated on heap)
The big difference between the cost happens in the way it is used in practice. (# OpenGL redraws) is hugely higher than (# geometry edits). This is because most of the time users navigate the 3d space. Even when a user rotates opengl camera by 90 degrees, if it goes smoothly there will be 100 frames for that move itself. But for an entire 30 minutes session he would only do less than 100 edits to the geometry. Putting the overhead of generating C++ instances from m_vlist to every opengl draw frame IMO is more costly since it is roughly the cost to clone the list.
Maybe we can optimize case 2 further by doing m_vlist > c++ classes conversion only for changes geometry .
Not sure I understood stuff correctly.
@Daniel Rossberg
Sadeep Darshana (Jun 11 2020 at 18:53):I implemented multiple document support to the application today. Now we can open and work with several databases.
Sadeep Darshana (Jun 11 2020 at 19:00):The grid is very ugly. I need to make it fade away with the distance to the camera. Otherwise everything in far horizon looks like a highly concentrated mess of lines. But this might require shaders. Not sure if I should prioritize on something else.
Daniel Rossberg (Jun 11 2020 at 19:04):Calling Iterate() is cheap. It does, what the usual iteration over a bn_vlist does: It uses BU_LIST_FOR() and has switch/case. The Element classes it constructs are cheap too: They need only a minimal amount of stack memory (no memory allocation on the heap at all) and all methods necessary to construct them are inline. This can be optimized to almost nothing. The whole procedure is very close to what is done with the bn_vlist in mged/archer.
Sadeep Darshana (Jun 11 2020 at 19:09):I'll proceed with that way. Is there a place I can download .g models?. I searched in the internet. I couldn't find any.
Daniel Rossberg (Jun 11 2020 at 19:14):They did some efforts to optimize the time consumed by handling vlists in BRL-CAD. If they did it well, the coreInterface should gain profit from it too by not using std::vector or std::list and not using heap memory - but using the original structs and algorithms.
Sadeep Darshana (Jun 11 2020 at 19:14): Daniel Rossberg (Jun 11 2020 at 19:14):You can find .g's in your BRL-CAD installation at share/db.

Daniel Rossberg (Jun 11 2020 at 19:18):
- Should I plot for each object or each object in root level in the tree? (i.e does ploting an object recursively plots its children too?)
Plotting is recursive. You should plot whatever was selected from the objets' tree.
- Does BRLCAD::ConstDatabase::TopObjectIterator return all objects or all objects in root level?
Only the ones at root level. See https://github.com/drossberg/BrlCadGUI/blob/master/src/MainWindow.cpp#L179 for an algorithm to walk down the objects tree if you know the roots.
Sadeep Darshana (Jun 11 2020 at 19:23):Thanks. I will implement the DM and commit everything I did in the past days.
Also what do you think about (not) committing WIP code? I have a lot of log statements and code I write just for experimenting without implementing the real thing in a solid manner. How should I deal with this (in the future)?
Daniel Rossberg (Jun 11 2020 at 19:24):Sadeep Darshana said:

Yes, might be time consuming.
BTW, did you know that struct and class are almost the same in C++? The only difference is, that for a struct the default visibility is public, but for a class it's private. I.e., if your class is the same as a struct with with 3 doubles and a trivial, inline constructor - and a pointer to a virtual function table.

If it compiles, commit it. This gives yourself check points too, where you can follow your progress. You may reject some of them while your development progresses, but you can always look back and have a rethink.
And your mentors can see if you run in avoidable trouble and help you.
Daniel Rossberg (Jun 11 2020 at 19:34):All in all, it sounds promising what you are doing. And I know that the display manager stuff is hard. This isn't a 3 days thing. I expect you to work on it the whole summer. Every time you implement a new feature, you may need to adapt something in the DM.
Sadeep Darshana (Jun 11 2020 at 19:48):It compiles. I committed it and pushed.
Inder Singh (Jun 12 2020 at 19:03):Hi @Sadeep DarshanaCongratulations on getting started with the coding part. Just a suggestion, it would be really helpful to add some description and a very quick readme file to the project. :) If we keep our documentation maintained from now onwards, it won't be difficult at the end.

Some of the variables here (corresponding ones in our implementation) will be used across multiple Elements. I can declare them static in the class or declare them in the header outside any class. I believe this won't have any performance impact though they aren't declared in stack.
Daniel Rossberg (Jun 13 2020 at 08:58):These would be member variables of class ElementOpenGL in my example.
Sadeep Darshana (Jun 13 2020 at 12:54):I am trying to getting the DM into working. It doesn't display stuff correctly. And opengl is not updating.

Sadeep Darshana (Jun 13 2020 at 17:12):DM working now.
What's the thing with objects having different colors in archer and mged? Are the colors a property of these objects? (as opposed to they being an indicator). Where is it implemented (the 17 commands of vlist don't seem to have a setColor)
This is slower than archer or mged (smoothness when rotating camera). It's hardly noticeable. But noticeable if you specifically try to notice that.
Could this be since I'm using perspective projection? I'm in the mid of implementing Orthographic btw)

It should be a bit slower because of the C++ interface overhead.
Sadeep Darshana (Jun 13 2020 at 17:28):I think I need to change the way of rotating and moving camera.
Should I look into how it is done in Archer?

Did you check out the g3d repo starseeker mentioned? It has three working camera implementations in there including one that works the same as Archer, another that works like Blender, and another that works like a lot of games.
Sean (Jun 15 2020 at 14:57):The initial zoom level is based on the overall bounding box of the geometry when it's displayed. This is calculated pretty quickly.

Colors are actually a bit of a complicated subject. Yes, they are a property of geometry. There are a variety of rules for how colors work. The summary is that there are essentially three ways an object gets a color.
First and most simple is an object can have a color specified directly on that object. This is stored as an attribute on the object.
Second, an object can inherit a color from a parent object. For example, say you have some "engine" object and way down the hierarchy there is a "bolt". We can set a color on engine and bolt can inherit the color when it's displayed in the context of an engine. In this manner, bolt will not have a color if it's displayed by itself (i.e., NOT in context of an engine).
Third, an object's color may come from a global color table. For regions and object belonging to a region, they have a numeric identifier set on them as an attribute (e.g., regionID is "1000"). The color table can specify all objects 1000-3000, for example, are rgb 255/0/0.
There is not a succinct function to get an object's color, but you can find the core logic in a few places throughout the code. The cleanest appears to be in src/libged/display_list.c, start with the color_soltab() function.

I did look at this. I could not get it built since it required some Orge to build. So I gave up on that. I will look at the camera code in it.
Sadeep Darshana (Jun 17 2020 at 17:33):I'm trying to get rid of the windows title bar. It's just a waste of space, ugly and almost all apps in 2020 (VS, all jetbrains products, adobe all, chrome) use their own. There is no straight forward way to do this in qt it seems.
Daniel Rossberg (Jun 17 2020 at 17:47):You can try to set the flags parameter of the QMainWindow constructor appropriately.
BTW, I don't like it if an application doesn't has it ;)
Sadeep Darshana (Jun 17 2020 at 18:38):That of course is the first thing I tried. Qt::FramelessWindowHint and Qt::CustomizeWindowHint exist. But when those flags are set the OS (at least Windows) do not treat the window as a normal window. No resizing possible. Clicking the taskbar icon doesn't minimize the application. No moving. No Aero Snap.
Community seems to be using this https://github.com/dfct/TrueFramelessWindow. It uses native win32 calls and do stuff. Problem with this is you can't select close by moving cursor to the top right corner (because there is like 1px border around the button, I'm trying to figure out where this comes from). So you need to move a very small amount towards center from corner which is inconvenient.
Sadeep Darshana (Jun 17 2020 at 21:52):@Daniel Rossberg I implemented rendering directly from bn_vlist too. Now we can choose between using VectorList and bn_vlist.
(change bool ArbalestSettings::useLegacyVlists)
I did this mostly to evaluate the performance differences. For share/db/goliath.g, bn_vlist renderer works seamlessly (similar to Archer/MGED). VectorList renderer is noticeably slower.
Did we consider the potential overhead of creating a function stack for each element? I think that might be more expensive than class instantiating. Also I had to dynamic_cast Elements, I believe this does not cost much.
Btw im accessing the underlying C list from VectorList for bn_vlist renderer. Are we going to continue having support for both methods? (will have to create a getter for VectorList::m_vlist if so)
Sadeep Darshana (Jun 17 2020 at 21:58):Also check if I'm doing anything incorrectly when using VectorList (resulting in bad performance)
Daniel Rossberg (Jun 18 2020 at 17:54):Sadeep Darshana said:
That of course is the first thing I tried. Qt::FramelessWindowHint and Qt::CustomizeWindowHint exist. But...
Or Qt::WindowFlags() | Qt::CustomizeWindowHint. But, this only removes the standard decoration. I.e., you have to draw your own one by hand now, give it a frame, put the minimize, maximize, and close buttons in the menu bar, etc. - I think. I haven't tried it by myself yet.
Sadeep Darshana (Jun 18 2020 at 18:38):I've been studying libged and tclcad. It is doing a lot underneath before generating vlists. Without this we are losing all the colors and other effects.
Sadeep Darshana (Jun 19 2020 at 19:59):I did not do any new implementations. Trying to understand the code in the BRLCAD repo. Now I have a better understanding of how libged, display_lists and dm (I was only familiar with drawVList method) works.
Even the lists are weird :speechless:
Sadeep Darshana (Jun 21 2020 at 13:15):@Sean @Daniel Rossberg @pooh (Inderpreet Singh) The amount of things we need to do to re-implement the geometry displaying as it is done in the 2 existing editors code is huge. So far I was just displaying the vlist obtained from ft_plot (generated for the whole tree at once by passing all the leaf nodes, therefore all solids are same style/color, I'm using ConstDatabase::Plot for this). I'm passing this vlist to my drawVList() implementation (I have not implement other methods in dm). But when I study the code for Archer, I realize that in archer the logic is lot more complex than this.
I have been studying the methods in libdm, libged and libtclcad. I see several choices here,
If going with 1, should I put the implementation under coreinterfaces?
If going with 2, do you recommend implementing a minimal subset of feature in C++ or linking libdm, libged and libtclcad?
If going with 3, single color wireplots don't look pretty
Sadeep Darshana (Jun 21 2020 at 13:38):Although I talked mainly about color enabling color and display_lists, in archer it does a lot more than that in addition to displaying wireframes. Likely it will take too long to integrate that all. My preference is 2. implementing the minimal features in C++ without using the libraries. (if using libraries we'll have to deal with BU_LISTS etc)
starseeker (Jun 21 2020 at 14:59):Until they respond, I have a smaller but potentially helpful/useful task: the qged code in the branch qtged SVN branch:
https://sourceforge.net/p/brlcad/code/HEAD/tree/brlcad/branches/qtged/src/qged/
has an accordion widget: https://sourceforge.net/p/brlcad/code/HEAD/tree/brlcad/branches/qtged/src/qged/QAccordionWidget.cxx
This widget needs some behavioral refinements - in particular, if all the accordion panels are closed, the spacing of the widget gets strange and it loses it's prior width. This widget will likely be useful in the future, and should be fairly "stand-alone" to work on.
The qged code itself can be built with -DBRLCAD_ENABLE_QT=ON set for CMake - there is no display code, but if you open a .g file (share/db/pinewood.g is the one I usually used) you should be able to do a variety of GUI manipulations.
There are other widgets there that need some work - the tree widget, for example, has graphical elements that don't quite line up properly when the tree is expanded - if you get through the accordion widget quickly.
Sadeep Darshana (Jun 21 2020 at 15:55):I'll look at this @starseeker thanks
starseeker (Jun 21 2020 at 18:13):Another challenge - the CADTreeView horizontal scrollbar doesn't seem to be working correctly - it is present, but doesn't calibrate correctly to the tree contents.
starseeker (Jun 21 2020 at 18:14):https://stackoverflow.com/questions/6625188/qtreeview-horizontal-scrollbar-problems might be a place to start, but it's been to long and I don't know if what they're discussing there is relevant to our code...
starseeker (Jun 21 2020 at 18:15):equally likely (or even more likely) that some calculation in our code is off...
Daniel Rossberg (Jun 21 2020 at 18:41):@Sadeep Darshana These are good questions. They show, that you made progress.
At first, you should be aware that you won't be able to program a complete CAD GUI in 3 months. I.e., you have to set priorities for yourself.
I personally wouldn't support the idea of using libged functions, because I'm afraid of not being able to extend them with new CAD features, if they are not implemented with the GUI code. You project is not about writing a new mged or archer, but a new generation graphical user interface, like someone would expect it from AutoCAD, for example. Maybe, the other mentors have a slightly different opinion here.
And, I don't see such a big problem with the colors. I have a model, where mged displays black edges on a dark-blue background (because the objects are black). This would be impossible for a CAD. There, it is important to have a good contrast.
To work on different things can be good to keep the code flowing and wait for inspiration on the areas where you got stuck.
Sadeep Darshana (Jun 22 2020 at 19:55):I'm making support for displaylists in C++ code. (this does solve the issue with the colors too)
Sean (Jun 25 2020 at 22:00):@Sadeep Darshana I also agree that those are/were fantastic questions. I think any of the three would be perfectly reasonable next steps to work on. That said, I wouldn't put colors on the priority list. I think we'll get far more mileage and usefulness if you keep working on other aspects.
I agree with Daniel in that I wouldn't think it a great approach to use libged for aspects of GUI drawing. That said, I do think it would be awesome to be able to call some GED commands on opened geometry (e.g., call the search command or ls command or l command to introspect, etc). How to go about is up for interpretation.
Sean (Jun 25 2020 at 22:03):I'd think you'd probably get the most mileage merging the features of qtged and getting other basic aspects of the GUI sorted out (e.g., full screen, windowed, drag-n-drop, etc.). Then, maybe work on getting triangle display lists working as an alternative to wireframes (similar to ft_plot, uses ft_tess).
starseeker (Jun 25 2020 at 22:18):FWIW, qged can already run ls and search on a .g file...
Sean (Jun 25 2020 at 22:22):@Sadeep Darshana Also, since you are already working on display lists, please keep in mind that it's perfectly viable to add new/additional functions not only to MOOSE but to the other low-level libraries as well as well. for example, there's no reason you can't add a new function to librt or libwdb or [insert lib] so long as it's within scope of the library. for example, the code you wrote for ft_plot traversal would easily make sense as a general function somewhere: given an object, get its wireframe.
Sean (Jun 25 2020 at 22:25):only difference is moose should be pure/clean c++. the low-level libs can be implemented in c++, but their public API need to get marshaled via C data types.
Inder Singh (Jun 26 2020 at 12:43):Hey @Sadeep Darshana what time zone are you in? Nothing major, I was just looking through your dev log and found entries for 27th June already :D so was confused.
Inder Singh (Jun 26 2020 at 12:47):Sadeep Darshana said:
Thanks. I will implement the DM and commit everything I did in the past days.
Also what do you think about (not) committing WIP code? I have a lot of log statements and code I write just for experimenting without implementing the real thing in a solid manner. How should I deal with this (in the future)?
The unofficial official motto of open source dev is "commit small, commit often" - and I would go to length and say, whenever you leave your computer for a break, make a commit (as daniel said if it compiles, its good enough to commit). Also, those commits would be really helpful in your evaluations. It's just another way of communicating progress and showcasing your workflow.
You can use the branch -> Pull Request workflow to keep things organized. I would suggest you keep committing in a feature branch, and then send a PR to the dev branch and once the code is reviewed by someone, it can be merged in to the main codebase/ master branch.
@Sean should we move/clone sadeep's code in the official GitHub org we have?

@pooh (Inderpreet Singh)
Sadeep Darshana (Jun 26 2020 at 13:32):Feature branch sounds like a good idea.
Sean (Jun 26 2020 at 17:07):@Sadeep Darshana so curious, did you compare the performance of vlist with VectorList?
Sean (Jun 26 2020 at 17:11):pooh (Inderpreet Singh) said:
Sean should we move/clone sadeep's code in the official GitHub org we have?
Yes, I would think it could have even started there, but no worries. It would be good to get it all together in one place.
Sadeep Darshana (Jun 26 2020 at 17:14):I did. VectorList is noticeably slower. Can feel the difference when rotating the camera with mouse. I did not do any time measuring (can do it if required)
But this does not matter anymore since I'm using displaylists and drawVList is not called every frame. So I deleted the vlist implementation (should be there in the older commits).
Sadeep Darshana (Jun 26 2020 at 17:17):@Sean I implemented color and style (DM_DASHED_LINE) to displaylist. I wonder why everything is so complex in the old libs. Is the underlying logic behind them really that complex?
Sean (Jun 26 2020 at 17:35):It's not required. Just curious about the performance, and good to know. We should try some models with a more typical level of detail, thousands of objects and instances.
Sean (Jun 26 2020 at 17:37):The underlying logic is pretty complicated. It's almost guaranteed that your wireframe colors will not match the actual ray tracing colors. A lot of the complexity is also accumulation of optimizations, feature creep, and complexity of procedural code.
Sean (Jun 26 2020 at 17:39):@Sadeep Darshana Instances add a fair bit of complexity, for example. Say you have a bolt on a truck. It keeps track of one copy of that bolt as it might be used 10,000 times around the vehicle and you don't want 10,000 copies of it in memory.
Sean (Jun 26 2020 at 17:40):Yet while you might have only 1 copy of the bolt, the instances of the bolt might be different colors .. which has to be kept track of separately.
Sadeep Darshana (Jun 26 2020 at 17:49):I did not think of any of these. This is my whole color / styling logic
if (tsp->ts_mater.ma_color_valid) {
gr->setFGColor(tsp->ts_mater.ma_color[0], tsp->ts_mater.ma_color[1], tsp->ts_mater.ma_color[2], 1);
}
else {
gr->setFGColor(gr->defaultWireColor[0], gr->defaultWireColor[1], gr->defaultWireColor[2], 1);
}
gr->setLineAttr(-1,tsp->ts_sofar & (TS_SOFAR_MINUS|TS_SOFAR_INTER));
There were few cases I had noticed but not yet implemented like the DM options for overriding solid's colors
starseeker (Jun 26 2020 at 17:52):@Sadeep Darshana did anything come of the camera modes from the old OGRE code?
Sadeep Darshana (Jun 26 2020 at 17:59):@starseeker I created my own implementation since I couldn't anyway use g3d as it is. I did not study g3d a lot.
Sadeep Darshana (Jun 26 2020 at 19:33):@Sean In my implementations I have used the C methods like db tree walk, also in the above code if you notice. How do I deal with this? My implementations are certainly not worth to be put among the old C libs since the functionalities are a subset of what's already there. SHould I use them through a coreinterface interface?
Sadeep Darshana (Jun 26 2020 at 19:34):my specific need here is db_walk_tree. Do I need to wrap it?
Sean (Jun 26 2020 at 19:35):you should -- I believe it's called elsewhere wrapped
Sadeep Darshana (Jul 02 2020 at 19:41):Do I need to implement immediate mode (no display lists). I created this partially for debugging qged. But it is very badly optimized (ft_plot everyframe). Need to make some changes if keeping it as a feature. Do we need to support it? @Sean
Sadeep Darshana (Jul 02 2020 at 19:42):I can remove it thing alternatively
Sean (Jul 02 2020 at 22:18):Immediate mode is dead.
Sean (Jul 02 2020 at 22:20):Any new code should be using "the new way" via opengl 4, vulkan, or a lib that wraps one of them.
Sadeep Darshana (Jul 03 2020 at 05:48):What about fixed function pipeline?
The new way is to use shaders for everything. Yet everything is done in the BRL-CAD with the old way. Everywhere in the internet they say FFP is deprecated and should not be used.
Just asking, updating to this would need a radical change from the existing code.
Sean (Jul 03 2020 at 05:50):The new way is not so different from what is already used in BRL-CAD for display lists.
Sean (Jul 03 2020 at 05:51):The data can be just filled into a vertex buffer + glDrawArrays(), e.g., https://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_05
Sean (Jul 03 2020 at 05:52):at least it's that simple for drawing points, wireframes, and polygons
Erik (Jul 03 2020 at 13:16):probably might be worth thinking about changing glColor stuff to fragment shaders some day if it's still there O.o ffp is dead, yo
Daniel Rossberg (Jul 03 2020 at 13:22):I'm in doubt if it is reasonable to put much effort in tweaking the OpenGL code. There is a new Qt 3D API in development https://doc.qt.io/qt-5/qt3d-index.html which puts an abstraction layer above the rendering engine. Especially on Windows the performance of Direct3D is usually better than OpenGL. In addition, OpenGL don't run everywhere.
Instead, you shouldn't forget the other aspects of the GUI. For example the creation and modification of database objects, or an undo/redo feature. You can't implement everything in these 3 months, but you should aim for creating a framework where the biggest issues are already addressed (not necessarily solved!).
Erik (Jul 03 2020 at 13:24):fair. :)
Erik (Jul 03 2020 at 13:24):undo/redo tree would be... nice.
Sean (Jul 03 2020 at 13:37):Qt3D is definitely the way to go. I meant more that you shouldn't need to be modifying existing code radically either way, not to suggest working on OpenGL makes sense beyond just getting/keeping the demonstration working.
Sadeep Darshana (Jul 03 2020 at 14:38):How do I wrap db_walk_tree? It contains complex structs (which themselves consist of more structs) like db_tree_state, db_full_path, rt_db_internal, bg_tess_tol, bn_tol.
Sadeep Darshana (Jul 03 2020 at 20:07):Is std::vector<std::string> preferred over char** to pass a list of names? (when developing on top of coreinterfaces)
Sadeep Darshana (Jul 03 2020 at 22:13):@Daniel Rossberg
Please review this https://sourceforge.net/p/brlcad/patches/546/ and let me know if/how this can be improved.
It wraps db_walk_tree.
For your convenience, this is how it is accessed from the outside,
https://github.com/sadeepdarshana/arbalest/blob/9188c17c074da7355579d26ee83933fa06199d0f/src/display/GeometryRenderer.cpp: line 63 and void GeometryRenderer::drawSolid method (line 73 onwards)
Sadeep Darshana (Jul 03 2020 at 22:25):@Daniel Rossberg @Sean What is the criteria for making the wireframe lines dashed (I have already implemented this).
What do these mean TS_SOFAR_MINUS, TS_SOFAR_INTER? SOFAR as in "so far as we traverse in the db"?
Need to implement an accessor to tsp->ts_sofar in coreinterface (TreeLeaf) with a meaningful name
Sadeep Darshana (Jul 03 2020 at 22:27):Now the codebase fully depends on coreinterfaces. No access to low level code.
Erik (Jul 04 2020 at 13:45):@Sadeep Darshana take a moment to read about serialization, these are the same challenges as db_walk_tree
Sadeep Darshana (Jul 04 2020 at 13:50):@Erik thanks, I will. Btw I'm not reimplementing the feature. I want to wrap the C method in coreinterface and give a more convenient interface to the outside.
Erik (Jul 04 2020 at 13:53):Yeah, it should follow python idiomatic design, the recursive serialization pattern shows what you will need to worry about as you bridge the two paradigms :)
Erik (Jul 04 2020 at 13:54):Eh, python or qt or whatever, it's how to get all the right data to shove it in another system
Daniel Rossberg (Jul 04 2020 at 16:49):Sadeep Darshana said:

Why do you want to do this? The C++ core interface has already a tree walking mechanism. I pointed you to an example where this mechanism is used to create an object tree widget in Qt.
Daniel Rossberg (Jul 04 2020 at 17:03):BTW, it looks like you abuse the auto specifier. You use it mainly (only?) at places, where you could write the concrete type as well. Whereas it's less typing, it makes it harder to understand the code (because you don't name the types) and find the places where a class is used.
Sadeep Darshana (Jul 04 2020 at 17:10):I didn't know that the functionality already existed. I thought that was only for top object. I'll change the code to use the existing implementation.
Daniel Rossberg (Jul 04 2020 at 17:18):Well, it's a combination of FirstTopObject() with TopObjectIterator and Get() with ObjectCallback().
Daniel Rossberg (Jul 04 2020 at 17:18):Look at the Qt object tree example.
Daniel Rossberg (Jul 04 2020 at 17:19):For the Plot() you have to play with Select() and UnSelectAll().
Daniel Rossberg (Jul 04 2020 at 17:23):And remember hat there is a difference between comm_shifter_box.r and all/Shifter/comm_shifter_box.r.
Sadeep Darshana (Jul 11 2020 at 20:27):
starseeker (Jul 11 2020 at 20:32):Neat!
starseeker (Jul 11 2020 at 21:01):@Sadeep Darshana did the docking stuff end up being too complicated to tangle with?
Sadeep Darshana (Jul 11 2020 at 21:10):No, I only have one (object tree) of them yet.
Daniel Rossberg (Jul 12 2020 at 15:10):Just looking at your code: You are using brlcad/vmath.h there. Did you considered to use QMatrix4x4 and QVector3D?
Sadeep Darshana (Jul 12 2020 at 15:28):I am thinking about changing that. It doesn't compile on linux due to brlcad/vmath.h. Also in windows I have to build twice after every CMake reload. In the first attempt it says can't find vmath.h. Works well after running build again.
If that is an alternative I'll use it.
Daniel Rossberg (Jul 12 2020 at 17:32):Try #include <vmath.h>.
The C++ core interface contains intentionally no vector functions, because it's expected that the project using it already has them. For example, a large framework like Qt has already types for matrices and vectors, and the basic algorithms like computing the inverse are build in. There is no need to mess with an additional library.
Daniel Rossberg (Jul 12 2020 at 17:34):BTW, the wireframe drawing works well on my computer :)
Sadeep Darshana (Jul 12 2020 at 19:38):Replaced the vmath.h with QMatrix4x4 and QVector3D. What is your platform? How well does the window work without the title bar?
Sadeep Darshana (Jul 12 2020 at 19:56):BTW daniel, did you look at my implementation of the traversing the tree for drawing (GeometryRenderer::DatabaseWalker)?
I was using std::string to pass the path as it traversed through the db. Is there a better way to access the objects than using the entire path?
I can have a single big (enough to hold the longest object path I might encounter) char array and append characters if creating an entire new string each time we go to a new db object is not fast enough.
Sadeep Darshana (Jul 12 2020 at 20:00):What was that thing about Select and UnSelectAll in ConstDatabase? I only used FirstTopObject() TopObjectIterator Get() ObjectCallback() for plotting.
Sadeep Darshana (Jul 12 2020 at 20:02):I couldn't understand the meaning by reading the doc. What is an active set?

I use Windows and Linux.

I don't know. I like the title bar.

There is nothing wrong with using std::string. It encapsulate the necessary memory management for the creation of object paths in a class. That's fine.
If there are better ways to access the objects depends on which information do you want to get and how much do you want to compute by yourself. With the Combination object you have access to all available information. It contains the complete Boolean tree with the operations and transformations. I.e., if you walk through the trees like you did in ObjectsTreeView and evaluate the transformations in addition, you get everything what's there.
Sadeep Darshana (Jul 13 2020 at 15:48):I don't know. I like the title bar.
You mean you like the native title bar? or the one that I implemented? When I said "How well does the window work without the title bar?" I meant does it look buggy without the native title bar?
Because it should. Some features like resize and " drag to top to maximize are not working". I have implemented dragging only out of the missing features
.
Daniel Rossberg (Jul 13 2020 at 15:49):Sadeep Darshana said:

Okay, I see. Indeed, plotting is a database operation, but it doesn't depend on Select() but gets the object name as parameter.
BTW, this Select() and UnSelectAll() is the equivalent to "e" or "draw" and "Z" in mged.
Sadeep Darshana (Jul 13 2020 at 15:50):So I won't need to use Select() and UnSelectAll()?
Sadeep Darshana (Jul 13 2020 at 15:57):I was working on UI and stylsheet processing.
I'm implementing object properties widget now.
As I understand I will have to determine the type of the object selected in the tree (Ellipsoid / Cone / Combination). Then look for the properties of the type in the corresponding coreinterface class. And display all of them.
What are the properties I cannot find this way?
Ex: Color
Where can I find a list of other such properties.
Daniel Rossberg (Jul 13 2020 at 15:58):Sadeep Darshana said:
So I want need to use Select() and UnSelectAll()?
They shouldn't be necessary. Your database->Plot(name,vectorList); seems to work. However, they are necessary for the ray-trace.
Daniel Rossberg (Jul 13 2020 at 16:00):You need to create a properties widget for every object type.
Daniel Rossberg (Jul 13 2020 at 16:00):The color is a property of Combination.
Sadeep Darshana (Jul 13 2020 at 16:02):When I look at QGED i see things like region, material id, aircode. I don't fully understand them. Maybe I should start using brlcad before developing.
Sadeep Darshana (Jul 13 2020 at 16:03):I'll follow the tutorial

Sean (Jul 13 2020 at 20:13):/me wonders why the Gift terminology was preserved... should probably just be GetMaterialID and SetMaterialID
Sadeep Darshana (Jul 14 2020 at 05:17):@Sean What is Gift terminology? the properties under Combination?
Daniel Rossberg (Jul 14 2020 at 06:22):Sean said:

You have both a legacy integer GIFT material (rt_comb_internal.GIFTmater) and a general string material (rt_comb_internal.material).
Sean (Jul 14 2020 at 06:24):I mean actual usage of the word GIFT .... nobody else knows what that means :)
Sean (Jul 14 2020 at 06:24):it's just an id number
Sean (Jul 14 2020 at 06:34):also, I believe the "material" string ... is a carryover from v4. I think it presently is only set to gift%d on v4 databases and not actually used by anything. the number is just the material ID. I think our intention should be to eliminate GIFTmaterial field and let material actually refer to a material object name (akin to shaders) when they get implemented. this has been a growing priority of late.
Daniel Rossberg (Jul 14 2020 at 06:43):Well, I'm still working with GIFT because one of the UniVeMo modules (programmed by another company) uses it. In general, programs like these don't need a designated material field. They have higher requirements on the material specification, which can better supported by universal attributes.
Sean (Jul 14 2020 at 06:44):conceptually, it's just an integer index to a name and a density value.
Sadeep Darshana (Jul 14 2020 at 06:44):🧐
Sean (Jul 14 2020 at 06:46):that certainly has a place, imho. it's the basis for massprops calculations. as a field, it's undeniably a fast index if it ever needed to be fast (which it almost certainly doesn't or couldn't be made automatic during prep)
Sean (Jul 14 2020 at 06:48):the fact that the value originated in gift isn't relevant or useful. it's not like it's a broad standard that conveys meaning. it's an index and one must have the accompanying table of names+densities (which are now embedded in the .g too). if all we ever wanted to support was density, it wouldn't exactly be a bad way.
Sean (Jul 14 2020 at 06:52):gqa / rtweight use the ID mapping for calculating mass, centroids, and moments of inertia. that alone gives the ID itself merit until there's an alternative.
Inder Singh (Jul 16 2020 at 06:40):Hi @Sadeep Darshana I see that your dev log has not been updated since 9th July. Just a gentle reminder, to update the dev log preferably daily.

- My current plan is,
Once I change an object which is not a combination, I will search the object tree for all paths ending with that object's name. Then remove each displaylist corresponding to each of such paths. Plot only such paths again and add each as a new displaylist.
If this is feasible? It sounds much more complicated than I had originally in mind. But, much better too.
Daniel Rossberg (Jul 21 2020 at 07:19):Sadeep Darshana said:
- When Ploting a single object I will have to traverse its entire path to find color info etc?
In principle, yes. You need to consider HasColor() and Inherit() there too.
Sadeep Darshana (Jul 21 2020 at 07:22):Refreshing the whole database is by no means affordable. We can't do things like dragging. At least not with something like goliath.g. It takes between 1 to 2 seconds for the model to load.
Sadeep Darshana (Jul 21 2020 at 07:23):We might be able to reduce this if using the C methods like archer does though. Archer is significantly faster at loading the database.

Sean (Jul 21 2020 at 20:47):That's awesome @Sadeep Darshana, looking good. How'd you ultimately go about handling colors? And what's next?
Sadeep Darshana (Jul 21 2020 at 21:03):@Sean I implemented editing geometry. Now implementing some handlers for textboxes that can be used to change the numbers.
Sadeep Darshana (Jul 21 2020 at 21:04):You mean wireframe colors?
I'm using the tree and getting the color inherited down from the ancestor Combination objects
Sean (Jul 21 2020 at 21:47):Right, but how are you getting the color from the ancestors?
Sean (Jul 21 2020 at 21:48):just curious what exact mechanism is being used given there's three color systems (direct color rgb values, inherited/overridden values, and based on the region_id)
Sadeep Darshana (Jul 21 2020 at 21:53):void GeometryRenderer::DatabaseWalker::operator()(const BRLCAD::Object& object) {
const BRLCAD::Combination* comb = dynamic_cast<const BRLCAD::Combination*>(&object);
if (comb != 0) {
if(comb->HasColor()) {
colorInfo.red = comb->Red();
colorInfo.green = comb->Green();
colorInfo.blue = comb->Blue();
colorInfo.hasColor = true;
}
ListTreeNode(comb->Tree());
}
else{
geometryRenderer.drawSolid(path.c_str(), colorInfo);
}
}
Not the complete code handling the color. But this is the core code. TODO Implement ignoring cases where Combination::Inherit()==false in the above code.

I made it so that the cursor changes to vertical drag icon when hovering over textboxes changeable by dragging. Might not be clear in the gif. I have seen a similar implementation somewhere (3Ds Max?). Wouldn't spin widgets give the impression you have to click on the up/down buttons rather than dragging?
Sadeep Darshana (Jul 23 2020 at 20:19):I implemented autoview.
Sadeep Darshana (Jul 23 2020 at 20:28):I selected (ConstDatabase::Select) all objects that are not combination for this. Is this necessary? (for the BoundingBox methods to work)

Did you use the code in libged or did you do something custom? How is it working?
Sean (Jul 24 2020 at 01:27):would be nice to match what mged/archer uses.. :)
Sadeep Darshana (Jul 24 2020 at 04:44):My camera implementation is different. I'll have change that also if I'm to match it.

If you want to select all (geometric) objects, you should Select() all top objects beside _GLOBAL.
Daniel Rossberg (Jul 26 2020 at 17:51):BTW, nice interface design :smiley:
Sadeep Darshana (Jul 26 2020 at 17:55):The code might not be of good quality in the latest several commits. I rushed to implement features using quick fixes. Need to fix those things
Sumagna Das (Jul 26 2020 at 18:02):@Sadeep Darshana the slider option from the new gui works very similarly to the slider options in blender but the new GUI is cool with support for opening multiple files at the same time :+1:
Sadeep Darshana (Jul 26 2020 at 18:21):I was sure I had seen that somewhere but couldnt recall where. So its blender.
Inder Singh (Jul 30 2020 at 02:11):@Sadeep Darshana I am loving the progress. Please keep your devlog updated. A daily dev log would be more helpful than a full week's log at once.
Sadeep Darshana (Aug 07 2020 at 20:21):@Daniel Rossberg My new rendering method only renders modified parts. Performance when modifying by dragging from my handlers went from practically impossible to use to seemless for goliath
However this would still not be efficient if a high level combination is modified since the whole subtree will be redrawn. This can only be solved by changing how combinations are rendered. In other words we need to save child objects in displaylists without their transformation available due to the position in object hierarchy. (save "wheel" instead of "cart/wheel"). And apply parent child transformations in the displaylist drawing time. I did not study how applying this currently happens in BRLCAD code. Without diving deep into this can't optimize this further.
Daniel Rossberg (Aug 08 2020 at 14:28):This sounds impressive. But, how can I modify by dragging? The Edit Menu entry seems to have no function.
A fully featured GUI needs an own data model, and the display lists are part of it. For example, it would need to emphasize the regions, because this are in fact the geometric objects. But, nobody expects you to implement this in 3 months. BTW, do you have a plan for creating a ray-traced image? (not required, just asking)
However, because this is the last Month in 2020's GSoC, you should aim for rounding Arbalest off, for example:

I meant the handles in text boxes (the icon changes when you hover on a property textbox). No handles have been implemented in the 3D GUI.
Sadeep Darshana (Aug 08 2020 at 14:45):Keeping the eye in the Objects tree view widget visible, if it is active(?)
I can do that. My original intention was to keep it only as a button rather than an indicator.
The text colors work as an indicator.
Each item in the tree can have one of 3 colors. Blue (subtree+itself[if leaf] fully visible), light blue (some children in the subtree are visible) and black (no child [or itself] in the subtree is visible).
Sadeep Darshana (Aug 08 2020 at 14:48):My current focus is to create properties for Combination.
These are the ones without properties pages,
BagOfTriangles
Combination
NMG
Pipe
Sketch

Ah yes, this was indeed seamless :smiley:
Sadeep Darshana (Aug 09 2020 at 17:34):Is it okay to display the transformation matrix in the UI instead of translate + rotation + scale + skew?
I've been struggling to extract components and then use these components to prepare the matrix back.
Sadeep Darshana (Aug 09 2020 at 17:35):(combination child node's matrix)
Sadeep Darshana (Aug 09 2020 at 20:15):btw raytracing done

Sadeep Darshana (Aug 09 2020 at 20:18):image.png
Current camera position and orientation are used for raytracing also
Daniel Rossberg (Aug 11 2020 at 15:50):@Sadeep Darshana, regarding the transformation matrix of the combinations: I would hide them by default. They could be shown on request, e.g. by clicking on a button. At first, it is only of interest, if a node has a transformation matrix different from the identity matrix or not. You could show the "Show Matrix" button for these entries only.
For me, it would be more interesting to see the tree structure of the combination with its Boolean operations.
BTW, you make still extensive use of auto, but I think, you shouldn't use it unless it really makes sense. If an inexperienced reader sees it, they don't know the type of the variable. In addition, it makes it hard to find the places where a distinct type is used (e.g. with grep). Reading through some articles discussing this issue, I got the impression, that people who know the code (classes, API used there) find it a reasonable way to make the code more readable, for every body else it makes the source code a riddle.
Daniel Rossberg (Aug 11 2020 at 15:50):PS: The File menu would need a Quit or Exit entry :)
Sadeep Darshana (Aug 11 2020 at 16:09):I'll remove the auto keyword. There are only 3 instances of the keyword I have forgotten to remove in all project files.
Sadeep Darshana (Aug 11 2020 at 16:10):debug_utils.cpp is not project, i removed that from CMake didn't delete the file just in case
Daniel Rossberg (Aug 11 2020 at 16:13):Okay, then it was bad luck that I saw one if theae remaining instances :}
Sadeep Darshana (Aug 11 2020 at 16:37):@Daniel Rossberg if no matrix is displayed shouldn't we provide a way to change the transformation? Display position / rotation etc?
Sadeep Darshana (Aug 12 2020 at 13:08):Transformation matrix is not having [0 0 0 1] as the last row. Why is this the case?
Daniel Rossberg (Aug 12 2020 at 17:01):Sadeep Darshana said:
Daniel Rossberg if no matrix is displayed shouldn't we provide a way to change the transformation? Display position / rotation etc?
Yes, if the combination can be edited. But, editing isn't possible in general, or am I missing something?
Sadeep Darshana (Aug 12 2020 at 17:02):I thought objects are movable :speechless:
Daniel Rossberg (Aug 12 2020 at 17:03):In arbalest?
Sadeep Darshana (Aug 12 2020 at 17:03):In BRLCAD?
Daniel Rossberg (Aug 12 2020 at 17:04):In mged or Archer: Yes. But, as far as I can see, the Edit menu in arbalest has no functionality(?)
Sadeep Darshana (Aug 12 2020 at 17:05):I am asking to implement the functionality
Sadeep Darshana (Aug 12 2020 at 17:06):Every BRLCAD::Object should be able to move rotate and scale, aren't they?
Sadeep Darshana (Aug 12 2020 at 17:06):Except the TopObjects
Daniel Rossberg (Aug 12 2020 at 17:07):Top objects too ;)
Sadeep Darshana (Aug 12 2020 at 17:07):I'm not sure I understand things correctly
Sadeep Darshana (Aug 12 2020 at 17:08):Isn't the position, rotation and scale stored in the node tree of the parent combination?
Daniel Rossberg (Aug 12 2020 at 17:09):You can move something around by giving an intermediate combination another transformation matrix - or by changing its content (points, vectors).
Sadeep Darshana (Aug 12 2020 at 17:10):oh yes. That I have implemented. (you are talking about changing Ellipsoid::Center right?)
Daniel Rossberg (Aug 12 2020 at 17:11):For example, the mged commands push and xpush changes the transformations from the matrices in the combinations to changes in the solids' parameters.
Daniel Rossberg (Aug 12 2020 at 17:11):Sadeep Darshana said:

Yes, for example.
Sadeep Darshana (Aug 12 2020 at 17:12):I noticed something weird when I was rotating things in Archer
Sadeep Darshana (Aug 12 2020 at 17:12):Instead of the object being rotated (which should chang its parent properties) it changed the properties of its children
Sadeep Darshana (Aug 12 2020 at 17:13):SO this was due to push and xpush?
Daniel Rossberg (Aug 12 2020 at 17:18):Maybe not the push command itself, but a similar functionality. It's often desired that the combinations have identity transformations. This way, the solids are still at the same place if selected separate.
Sadeep Darshana (Aug 12 2020 at 17:20):I'll look into this. This wouldn't be easy since math would be different for each object type. Isn't it?
Sadeep Darshana (Aug 12 2020 at 17:22):Btw I implemented a dark theme and raytracing. Did not make it possible to edit any parameters relating to raytracing.
Sadeep Darshana (Aug 12 2020 at 17:23):Which parameters need to be implemented for raytracing first (are there any?)?
Daniel Rossberg (Aug 12 2020 at 17:24):Sadeep Darshana said:

I recommend to stay with the background color for the moment.
Sadeep Darshana (Aug 12 2020 at 17:27):ah okay
About combinations I will display the translation, scale or quaternions if the matrix is not identity. No displaying of the matrix in any case and also no editing.
Daniel Rossberg (Aug 12 2020 at 17:29):Sadeep Darshana said:

There should be functions for this in the primitives (~_xform?) They need however to be included in the C++ interface.
Sadeep Darshana (Aug 12 2020 at 17:30):Let me know if about or license has to be changed. I copied the license from Archer. Also sketched something in illustrator for the icon.
Daniel Rossberg (Aug 12 2020 at 17:31):You don't need to mention the mentors in the About dialog ;) Especially not in the first place.
Daniel Rossberg (Aug 12 2020 at 17:31):You are the creator of Arbalest.
Sadeep Darshana (Aug 12 2020 at 17:33):For now I will focus on implementing functionalities that change the object tree? Moving objects in the tree, duplicating and creating new objects
Sadeep Darshana (Aug 12 2020 at 17:33):I had implemented creating last year
Sadeep Darshana (Aug 12 2020 at 17:33):Without creating the application will not be complete

"OPEN SOURCE

This is also from the website, not the formal agreement.
Daniel Rossberg (Aug 19 2020 at 18:33):Well yes, this matches with my impression: Under some circumstances it is possible to use these icons - but it's preferable to avoid them. If somebody else works with your code, they won't know about the conditions.

They are self-made. They are part of the BRL-CAD project.
The least thing you should do is to mention all other origins than yourself and what came from there. Do all icons8.com icons have the "icons8" prefix?

Sean (Aug 25 2020 at 01:48):It's always been a bit strange to me that one can't just put a matrix over any object (comb or primitive). Probably a carryover from comgeom days, but one we really should rectify in v6.

I can implement changing the matrix of a node in a combination. Is it recommended this be a feature?
I was thinking this was discouraged in favor of propagating rotate/scale/translate changes to the primitives via push / xpush.
@Sean
Sean (Aug 25 2020 at 06:26):For proper editing, you really need both the ability to have matrices in the hierarchy as well as the ability to push them down
Sean (Aug 25 2020 at 06:28):I'll also note that pushing is a relatively complex topic to do correctly in the general case without introducing xpush options for replicating geometry and detecting when a push must be prohibited (e.g., applying a non-uniform scale to a torus primitive is impossible to represent using the parameters of a torus)
Sean (Aug 25 2020 at 06:29):But yes, in general we want to be able to apply and edit a matrix at any node in a hierarchy.
Sadeep Darshana (Aug 25 2020 at 06:36):Sean said:

Is it okay to allow them to edit the 4x4 matrix directly? @Sean
Sadeep Darshana (Aug 25 2020 at 06:37):Does it have to be via individual components like translate / rotation / scale?
Sean (Aug 25 2020 at 06:38):They're stored as a homogeneous matrix
Sadeep Darshana (Aug 25 2020 at 06:46):I know.
But to allow it to be as a matrix rather than individual components?
Sadeep Darshana (Aug 25 2020 at 06:51):This is not something most programs allow. They allow rotating / moving / scaling but not changing a 4x4 table which is the matrix.
I'm asking should there be textboxes for x, y, z of translate (same with rotation and shear? and scale ). It will be hard since I will have to compose and decompose the matrix given translate/rotation/scale.
Sean (Aug 25 2020 at 06:52):The editing can be constrained to rotate/scale/translate, but it's stored as a matrix
Sadeep Darshana (Aug 25 2020 at 06:52):I'm asking instead of this is it okay to directly allow changing 4x4 matrix in the form of 16 text boxes through the UI
Sean (Aug 25 2020 at 06:53):I don't think you need to allow direct editing of the matrix at this point in time... no
Sean (Aug 25 2020 at 06:54):the problem is you're not going to reliably be able to tell what operations are encoded to display them
Sean (Aug 25 2020 at 06:54):if you just open an existing database with matrices, for example
Sean (Aug 25 2020 at 06:57):I mean you might be able to apply https://math.stackexchange.com/questions/237369/given-this-transformation-matrix-how-do-i-decompose-it-into-translation-rotati a large portion of the time, so maybe good enough. not sure what you'll do when it's not though.
Sadeep Darshana (Aug 25 2020 at 06:59):I looked at that stackexchange post and tried to implement that. The translate sometimes was different when there was a scale.
Sadeep Darshana (Aug 25 2020 at 06:59):in BRLCAD
Sadeep Darshana (Aug 25 2020 at 07:00):Sean said:
I don't think you need to allow direct editing of the matrix at this point in time... no
But Sean if it's unreliable shouldn't I be giving them direct access?
Sadeep Darshana (Aug 25 2020 at 07:02):I wouldn't be able to compose and decompose matrices. So the most reliable thing is to let them change the matrix directly. Wiithout taking the translate / scale/ rotation.
Sadeep Darshana (Aug 25 2020 at 07:03):Sean said:

This supports the opposite of
"I don't think you need to allow direct editing of the matrix at this point in time... no"

It's nearly impossible to directly edit a 4x4 matrix in any meaningful way except for existing simple matrices. The ones that can be edited are trivially decomposable.
Sean (Aug 25 2020 at 07:05):if it can't be decomposed and you support edits, that's more likely to just result in an invalid matrix
Sean (Aug 25 2020 at 07:06):that said, you can still allow scale/translate/rotate operations ... you just might not know what the current values are
Sean (Aug 25 2020 at 07:07):your interface could override the matrix with the values they input in that case
Sean (Aug 25 2020 at 07:08):you can allow the edits in absolute form because they can be encoded without issue even on top of some arbitrary existing matrix.
Sadeep Darshana (Aug 25 2020 at 07:11):you mean multiplying an existing matrix to apply an operation instead of [decomposing matrix->change components->compose matrix back] ?
Sadeep Darshana (Aug 25 2020 at 07:11):@Sean
Sean (Aug 25 2020 at 07:12):basically, yes
Sean (Aug 25 2020 at 07:12):at least in the cases where you can't decompose
Sadeep Darshana (Aug 25 2020 at 07:16):Okay I will do that.
How do I represent rotation for relative editing? quaternion? rotation around an axis?
Sean (Aug 25 2020 at 07:16):maybe display an icon or something to indicate that the operation is relative or simply disallow the edits if it can't be decomposed. you have choices, just saying you'll have to figure out some plan. there's not a great answer as the editing intent is lost.
Sean (Aug 25 2020 at 07:17):you just know it's 32, you don't know if it was 2 * 10 + 12 or 3 * 10 + 2 or 4 * 8 + 0 or ..
Sean (Aug 25 2020 at 07:17):(oversimplified of course)
Sadeep Darshana (Aug 27 2020 at 12:11):@Sean
I implemented the feature we discussed.
anim.gif
The method we discussed is not perfect since as you can see in the animation translate is applied before other operations. So relative scaling on top of the existing matrix leads to the whole object moving also. Same with rotating.
Also removed all the 3rd party icons from the repository.
Sean (Aug 27 2020 at 19:32):@Sadeep Darshana nice work!
Sean (Aug 27 2020 at 19:33):it won't work for primitives as they don't have any place to hang/retain the parameters, but for members of combinations, you could display this as a property panel
Sean (Aug 27 2020 at 19:33):something like this: 30.png
Sean (Aug 27 2020 at 19:34):or this: Scale10.jpg
Sean (Aug 27 2020 at 19:36):that way it also becomes clear that it's the reflective absolute state being described, not the relative edit operation, so it's consistent and can be adjusted incrementally or to absolute values without needing a checkbox or other GUI clutter
Sean (Aug 27 2020 at 20:08):here's another example how cinema4d presents it: Screen-Shot-2020-08-27-at-3.51.22-PM.png
Sean (Aug 27 2020 at 20:08):Video from https://www.youtube.com/watch?v=lz3cjEtaXpA
Sadeep Darshana (Aug 31 2020 at 14:47):This wouldn't be possible @Sean since I don't have access to the absolute values as we discussed earlier. I am merely taking the existing matrix and apply a transformation to it. I do not know the absolute Position / Rotation / Scale values of the previous (before user changes) state or after.
Sadeep Darshana (Aug 31 2020 at 14:48):@Daniel Rossberg @Sean @pooh (Inderpreet Singh)

Daniel Rossberg (Sep 01 2020 at 06:41):One possibility would be to move it to https://github.com/BRL-CAD. It is legitimate to see it as an independent program.
I hesitate to add it to rt^3, at least at the moment, and would like to wait until the main repository is moved to github. Then, it can be included in rt^3 as a submodule.

I.e., if this doesn't end with a kind of pull request at BRL-CAD, we should probably better fork it there.

Sadeep Darshana (Sep 04 2020 at 17:25):How do we proceed with placing the project to https://github.com/BRL-CAD?
I can't do it since I don't have the create repository permission in https://github.com/BRL-CAD
@Sean @Daniel Rossberg
Daniel Rossberg (Sep 04 2020 at 17:27):I think that the best would be to fork it on ttps://github.com/BRL-CAD.
Sean (Sep 05 2020 at 04:43):@Sadeep Darshana I got distracted/interrupted the other day working on GitHub permissions. I think the best preserving option will be for you to initiate a transfer (you will have create repository permission once I fix it) so it becomes authoritative for all and includes your entire commit history. I'm looking at the permissions now.
Sadeep Darshana (Sep 05 2020 at 04:45):great
Sean (Sep 05 2020 at 04:46):Sadeep Darshana said:
https://github.com/sadeepdarshana/arbalest link will still be accessible isn't it (or redirected)? Because that is the one I submitted for GSoC evaluation.
That should still be possible. At most, you might have to fork it back to yourself so upstream/downstream work right.
Sean (Sep 05 2020 at 04:47):Also, the link you submitted is mostly for our benefit, but I can certainly sort things out with OSPO if needed.
Sean (Sep 05 2020 at 07:54):@Sadeep Darshana I have to get some rest, but would you give it a try now? The default permissions should allow you to initiate the transfer once you accept the member invitation.
Sean (Sep 05 2020 at 08:29):the steps are at https://help.github.jp/enterprise/2.11/user/articles/transferring-a-repository-owned-by-your-personal-account/
Sadeep Darshana (Sep 05 2020 at 16:57):@Sean I transferred the repo. https://github.com/BRL-CAD/arbalest
The old link is working fine. It redirects to the new location.
The readme is outdated. I will update it tomorrow if possible.
Daniel Rossberg (Sep 09 2020 at 06:29):@Sadeep Darshana, please have a look at https://github.com/BRL-CAD/arbalest/pull/8
Sadeep Darshana (Sep 09 2020 at 06:49):merged it @Daniel Rossberg
Daniel Rossberg (Sep 09 2020 at 06:52):And tested it? I was wondering why this section was in the config.
Sadeep Darshana (Sep 12 2020 at 08:19):Tested. It works fine. I might have added it when I was experimenting with windows window system to remove title bar and still retain other functionalities associated with it.
Daniel Rossberg (Sep 15 2020 at 10:50):@Sadeep Darshana, I created a new pull request: https://github.com/BRL-CAD/arbalest/pull/9
I could merge it by myself, but I want you to have a look at it too. For example, I removed the glm library and replaced it with Qt methods. However, was there a reason why you didn't use Qt?
Sadeep Darshana (Sep 16 2020 at 12:58):I checkedout https://github.com/drossberg/arbalest. This is working fine on Windows, Visual Studio.
I didn't know Qt already had these features until the very end of the project. I used what was seeing everywhere on the internet for GL math.
I actually thought of changing them to use Qt functions once I got to know. This is great.
Sadeep Darshana (Sep 16 2020 at 13:04):What do you think of my use of circular dependency? I only realized later that this was very inconvenient in C++ unlike in Java/C#. Everytime I do some change or addition in the includes of most files a lot of errors come up due to header including / forward declaration related errors etc.
Daniel Rossberg (Sep 16 2020 at 14:02):To be honest, I haven't noticed the circular dependencies yet.
However, there are some more flaws in the code too. E.g., transformationMatrix in MatrixTransformationWidget.cpp is allocated on the heap but never freed. I.e., a code review is necessary anyway. But, this isn't surprising after a step in a new direction.
Sadeep Darshana (Sep 16 2020 at 14:20):I've been using C++ in algorithm contests. But this is the first software I created.
starseeker (Sep 16 2020 at 14:51):@Sadeep Darshana I know it's not your primary focus, but any chance you could back-port those changes to the qged code as well?
Daniel Rossberg (Sep 16 2020 at 15:04):arbalest is a very nice peace of software. I like the modern look and feel. Especially, GUI apllication source code tends to become messy if developed fast from the scratch. But, you managed to implement a new GUI concept for BRL-CAD.
Sean (Sep 16 2020 at 17:20):@Sadeep Darshana that was your first software creation!? That's amazing. You should be very proud; I'm impressed!
Sean (Sep 16 2020 at 17:23):Instead of backporting, it may make more sense at this point to forward-merge qged into arbalest. I'm not intimately familiar with the differences but do like the fresh physically separated architecture. They both use the same hierarchy widget now, yes? Main aspect missing I believe is the ability to invoke ged commands?
Sean (Sep 16 2020 at 17:26):@Sadeep Darshana do you have or can you make a short 5-30 sec screencap video showcasing the GUI how it ended up by the end of GSoC? I posted one you gave me from a couple months ago, but it'd be nice to showcase the finale too. Something with an interesting hierarchical model like m35 or something downloaded..
Sadeep Darshana (Sep 16 2020 at 17:27):I will create one @Sean

The best way would be to implement ged commands into coreinterface and make arbalest use it, isn't it?

First C++
starseeker (Sep 16 2020 at 17:52):The thing is, qged can integrate directly into the main BRL-CAD repo the way mged/archer do. Arbalest, as I understand it, doesn't and deliberately isn't intended to (since coreInterface also isn't intended to integrate into the main repo.)
starseeker (Sep 16 2020 at 17:54):Visually speaking, it looks like qged and arbalest have different hierarchy widgets. (qged's has an issue with newer Qt in my testing, but it's the one that sets the icons based on type and (at least when things are working properly) can do selection based highlighting of rows.)
starseeker (Sep 16 2020 at 18:01):Also not sure if things like the html based console widget, accordion widget, or docking setup have migrated?
starseeker (Sep 16 2020 at 18:04):Not really sure if they can be readily migrated to arbalest - would take some exploring - but I'd hate to lose some of those features...
starseeker (Sep 16 2020 at 18:04):On the plus side, ged_exec and friends should make exposing the GED commands much simpler...
Sean (Sep 16 2020 at 20:45):Sadeep Darshana said:

That's a great question. Probably as part of MOOSE (i.e. part of the larger API that includes coreInterface's OO hierarchy). It could be attached as a method on a Database object, but the GUI needs more access and control in order to automatically update views and such, so probably not there. It really begs for a stand-alone command executor interface that is hooked up to a database and has connections for getting update notifications.
Sean (Sep 16 2020 at 20:57):starseeker said:

Exposing them or even just directly calling them from inside a qt console is super easy already. The question would just be whether there's any benefit to wrapping it in an OO API or whether the app should just directly manage the ged state. Somewhere someone has to keep one informed of changes from the other (e.g., delete an object in the GUI, does ged see the deletion and vice versa).
starseeker (Sep 16 2020 at 20:58):I would prefer in some ways to have callback hooks at the .g read/write layer in libg...
Sean (Sep 16 2020 at 21:00):o.O
starseeker (Sep 16 2020 at 21:01):That's when the .g file actually changes, after all...
starseeker (Sep 16 2020 at 21:02):Right now I think we're trying to keep track of which GED commands potentially do what, which just feels wrong...
Sean (Sep 16 2020 at 21:02):that would be weird. I get it. but it would be unusual. callbacks typically implement app logic.
starseeker (Sep 16 2020 at 21:02):Well, generate DB_WRITE events of some sort then, if we have an events or signals system apps can hook into.
Sean (Sep 16 2020 at 21:04):I had envisioned that happening at the libged layer. After all, once it's fully abstracted, just about all that remains is an exec call, so the rest of it's role would be providing app connections
Sean (Sep 16 2020 at 21:04):callbacks or a public/subscribe system, definitely transactions
starseeker (Sep 16 2020 at 21:06):/me has a little trouble envisioning what that would look like, at least from a migration standpoint - would all librt level calls in libged commands be replaced with transaction event generation calls?
Sean (Sep 16 2020 at 21:06):was leaning towards an event based publish/subscribe system where invoking a command then generates a list of events and those events default to specific behaviors (i.e., what they currently do)
Sean (Sep 16 2020 at 21:08):starseeker said:
/me has a little trouble envisioning what that would look like, at least from a migration standpoint - would all librt level calls in libged commands be replaced with transaction event generation calls?
yes, exactly. so for a command like "killall foo" could return a transaction set filled with whatever relevant "DELETE [obj]" events.
starseeker (Sep 16 2020 at 21:09):So the first step is to design the transaction set and API?
Sean (Sep 16 2020 at 21:09):there would be a predefined set of possible events that we'd have to specify (i.e., all possible low-operations)
starseeker (Sep 16 2020 at 21:09):Would libg publish that set, or does that live at the libged level?
Sean (Sep 16 2020 at 21:10):I saw that living at the libged level as it introduces the concept of a command and command transactions
Sean (Sep 16 2020 at 21:11):it would have default handlers for things like KILL, MAKE, DRAW, ERASE, LIST, ... that would make the corresponding librt/libg call
starseeker (Sep 16 2020 at 21:12):OK, I think that makes sense.
starseeker (Sep 16 2020 at 21:13):As long as we don't have any situations where a command can't deduce it's transaction list without applying the previously generated transaction(s)...
Sean (Sep 16 2020 at 21:13):I see these default handlers actually getting far more interesting and advanced than our currently ad hoc logic. for example, a command that causes a new object to get created might generate a MAKE event, and the handler for MAKE would automatically 1) do the db_lookup to make sure it doesn't already exist 2) come up with a consistent name or error if it does exist based on some policy, 3) automatically be loggable or debuggable, 4) be automatically and consistently undo-able
Sean (Sep 16 2020 at 21:15):starseeker said:
As long as we don't have any situations where a command can't deduce it's transaction list without applying the previously generated transaction(s)...
that's a very important consideration, yes! (nice)
starseeker (Sep 16 2020 at 21:16):search -exec is what leaps to mind, but there may be others...
starseeker (Sep 16 2020 at 21:17):What to do about "commands" that are Tcl procs calling multiple GED commands is another one - do we build up all the transaction sets and then apply them at the end, or does each GED command finalize before moving on to the next one?
Sean (Sep 16 2020 at 21:17):I think it'd be on us in how transactions are ultimately validated and processed, but I think it's very tractable as there'd still be the call that's there now (e.g., wdb_export() becomes something like ged_make() or whatever) and inside that routine it would carry the current processing state.
Sean (Sep 16 2020 at 21:18):mind you, that processing state is a virtual environment
Sean (Sep 16 2020 at 21:18):but from the command's perspective, it will have occurred
starseeker (Sep 16 2020 at 21:21):But, for example, a loop that does a wdb_export and then later in the loop does a db_lookup on the object it just exported - if wdb_export is a transaction not applied, the db_lookup equivalent would have to check both the .g state and play the transaction set up to that point to answer the question of what the db_lookup is actually supposed to be. Am I missing something?
Sean (Sep 16 2020 at 21:21):so something like search -exec would be nested transactions in a parent transaction. and if you have a command like "mv a b" that does a RENAME a b event followed by a validation check to make sure b exists and a doesn't, those would likewise be updated.
Sean (Sep 16 2020 at 21:24):starseeker said:

Am I missing something?
we have choices here. even to make it play transactions, which is an option, we'd still have to inject ourselves somewhere in that command (e.g., replace all db_lookup with an identical ged_lookup)
starseeker (Sep 16 2020 at 21:25):Playing transactions though would get performance prohibitive as the building transaction set gets large. Don't we need another answer?
Sean (Sep 16 2020 at 21:25):and doing that, we could also not apply transactions inside the ged_lookup but instead just keep track of changes thus far to know what objects exist and dont' exist
Sean (Sep 16 2020 at 21:25):that would be even faster than what we currently do
Sean (Sep 16 2020 at 21:26):as all I/O would get deferred
Sean (Sep 16 2020 at 21:26):similarly, laying out our choices, we could do it fully passively
Sean (Sep 16 2020 at 21:26):like what svn and git do
Sean (Sep 16 2020 at 21:27):ged would have an inmem of the real deal, let the command actually do whatever it does to it, and then diff to determine the change events
Sean (Sep 16 2020 at 21:28):speaking of which, gdiff already has a strong notion of what this event system should look like
Sean (Sep 16 2020 at 21:28):as the things it can diff are akin to the events possible (at least for i/o events, there are also camera, view, and display events)
starseeker (Sep 16 2020 at 21:30):Is the transaction API what we'd then send over the capnproto channels when we go fully IPC for ged_exec execution?
starseeker (Sep 16 2020 at 21:31):Must confess that appeals as all ged commands become read-only on the .g file
Sean (Sep 16 2020 at 21:31):that would be my hope
starseeker (Sep 16 2020 at 21:31):Would solve a whole host of issues.
Sean (Sep 16 2020 at 21:31):would be good to survey and see if we actually have any commands that potentially rely on previous state besides search
starseeker (Sep 16 2020 at 21:32):OK, that establishes the order of implementation then - transaction API first, then IPC.

I don't know about any outcome of this student project. My POC uses the rt_dirbuild_inmem() function I implemented this summer (from scratch) via the C++ core interface and Sadeep's arbalest.
Himanshu (Mar 10 2022 at 15:28):How should I get started with https://github.com/opencax/GSoC/issues/27 ? I am able to build and run arblest.
Himanshu (Mar 10 2022 at 15:30):I saw Implement the C++ core classes for the remaining primitives but how should I get started? @Sean @Daniel Rossberg
Sean (Mar 10 2022 at 16:18):I'd probably look at one of the existing primitives that has a name that can be easily searched (e.g., torus), find all references to it, then find a primitive that is missing (look at all the subfolders in src/librt/primitives in the brlcad repo for a listing), and work to implement it
Sean (Mar 10 2022 at 16:23):You could also simply find a bug and fix it, you could also get qged up and running so you can compare against that, you could work on trying to make components in qged reusable in arbalest (e.g., the hierarchy view), you could also work on something unrelated to qged like setting up an interactive raytrace window, ... lots of possibilities ;)

This one got solved after I git pull and build and now 15 succeeded.
Sean (Mar 12 2022 at 21:50):@Himanshu Sekhar Nayak so are you built now or do you ahve the bu_jmpbuf unresolved symbols issue? that's basically saying you're missing libbu from the link list or missing BU_DLL_IMPORTS during compile

I still have bu_jmpbuf unresolved symbols issue.
Himanshu (Mar 13 2022 at 06:27):BRLCAD_BU_LIBRARY is able to find C:/Users/Himanshu/Desktop/WindowsBRLCAD/install/lib/libbu.lib
Sean (Mar 13 2022 at 07:20):@Himanshu Sekhar Nayak I know it's a hassle, but can you try deleting your build directory, recreate it, re-run cmake, and compile again? when repeatedly rebuilding through errors, sometimes object files will get compiled with wrong settings and it can help to make sure you start fresh. The fact that bv_vlist_copy went away and bu_setjmp_valid and bu_jmpbuf remained indicates the possibility.
Sean (Mar 13 2022 at 07:21):it'll also then be easier to inspect your log to make sure it's getting compiled... if you turn up the verbosity, we can check that BU_DLL_IMPORTS is being defined
Daniel Rossberg (Mar 13 2022 at 13:45):Cleaning up the CMake cache (or removing everything what's in the build directory) and re-running CMake with BRLCAD_BASE_DIR set would be my first idea too.

Some of them are getting not found. Is that okay? Screenshot-7_LI.jpg

Sean (Mar 13 2022 at 19:04):Yes but it matters when and if you’ve done a git pull and recompiled, etc. What did the summary say when you compiled brl-cad? Can also run rt and look at the usage statement for a version number.

Daniel Rossberg (Mar 15 2022 at 17:53):Sean said:
/me wonders what it needs the version number for…
Same reason why there is a brlcad_version.h. But this file wasn't always part of the public API. That's why rt^3 generates its own one.
However, if the BRL-CAD installation was found, it will be generated automatically. But if the installation wasn't found, CMake and the compiler will complain about every piece which isn't configured, including the version number.
Himanshu (Mar 22 2022 at 20:11):@Daniel Rossberg I am able to produce fully ray traced image by clicking on Reset the viewports and focus on the visible button having Z-axis to 0. Screenshot-12.png

I am taking a break due to my upcoming semester exams that is going to start from 29th March to 9th April. I hope I will not miss the deadline for sending an proposal after discussion with you and @Sean for this project.

One big difference between GCi and GSoC is that you have to make your own project plan for GSoC.

Only one subject is left and my exams will be over. Today, I started writing up the proposal and only added the personal information by following https://opencax.github.io/gsoc_guidelines.html.
Himanshu (Apr 06 2022 at 16:01):Once it is over, I will write the complete proposal.
Himanshu (Apr 08 2022 at 19:29):My exams got over. I am thinking to open issue in arbalest that I had spotted. Should I open the issue ?
Sean (Apr 09 2022 at 15:11):I mean that completely depends... why or why not?
Sean (Apr 09 2022 at 15:12):we know it's in development and has issues and room for improvement, so creating the issue if you're not going to work on it is not valuable. If you're going to create an issue to discuss and work on it, then sure.
Himanshu (Apr 09 2022 at 18:51):Yeah I will work upon on those issues so I thought that I should go on and upon the issue. And also I thought that to add those issues to my proposal for addressing.
Sean (Apr 09 2022 at 20:08):Sure that’s fine with me that way. I just don’t want to create busy work if the plan changes before it’s finalized, but if it helps you be more productive and it creates an intentional space for discussion, absolutely sounds fine
Himanshu (Apr 10 2022 at 14:27):One major thing I found that I think is not implemented yet is if I create a new file and draw a primitive and close the file by clicking X without saving then the untitled tab is removed. And also if I close the main GUI app having unsaved changes then the app got closed without asking to save the file or not.
Himanshu (Apr 10 2022 at 14:47):Another one I found that Help section is not showing anything.
Himanshu (Apr 10 2022 at 15:22):It should show manual I think.
Himanshu (Apr 11 2022 at 19:55):Btw where I can find the primitives headers in brlcad dir? Not talking about coreinterface.
Himanshu (Apr 12 2022 at 10:41):Is it include/rt/primitive? Because I found arb8.h there.
Himanshu (Apr 12 2022 at 10:45):I am just trying to match if every primitive matched with coreinterface to brlcad/ so that I don't miss any primitives that is not yet implemented
Daniel Rossberg (Apr 12 2022 at 18:54):The closest to a primitive header in the core BRL-CAD is include/rt/geom.h. If you are looking for the list of primitives, src/librt/primitives may contain what you are looking for. include/rt/defines.h contains the list of solid IDs.
Sean (Apr 13 2022 at 05:56):Yeah, src/librt/primitives/table.cop has all possible entities. Just beware that some are deprecated or obsoleted. You can probably ignore hf, cline, bspline, hrt, super, just to name a few that come to mind
Himanshu (Apr 13 2022 at 20:03):@Daniel Rossberg @Sean Which feature(s) I should try to implement? Like in mged there are too much options that are not found in arbalest yet. I have listed some of the feature that are not yet in arbalest which are the following:-
Alert box is missing that shows title after opening a .g file. There should be way to give title to a file? If this feature implemented then either it can be displayed in a bar which is currently showing the file path or when I hover mouse on the name of the tab . Or any suggestion?
title.jpg
The most important one I found that missing of status bar which includes angle of view, size of view, center and also changing the units. I think instead of showing file path in arbalest we can show the status bar.
statusBar.jpg
Currently Arbalest Help section is only showing Quick start . We can add a manual page which will be helpful but there is a part where it shows synopsis which shows a command but Arbalest didn't have a command line yet.
HelpSection.jpg
Manual.png
In mged, the create section have primitives like Arbs which contains arb8, arb7... but there is no such like in arbalest. It only includes arb8 instead of Arbs section. Same applies to cone and ellipsoids. May be we should try to import those into arbalest?
shift key grips and effects are not in arbalest. We can add those too.
There are many more features that can be implemented and many more I can explore what have been missing by comparing mged with arbalest. From above list of features, which will be important one? I am deciding to work on these and also the bugs that I have found during this GSoC. Since this is a long project, so I will write both improvements, fixes and features to arbalest.
Himanshu (Apr 14 2022 at 05:15):Btw I saw this project is 350hrs so it will come to end on November 21 or September 5-12? I am little confused here.

I think I should go with 175hrs.
Himanshu (Apr 14 2022 at 16:06):I am planning to propose bugs fix, add features and extend object-oriented C++ Geometry API.
Himanshu (Apr 14 2022 at 16:10):I can commit 4hrs/day.
Himanshu (Apr 14 2022 at 16:11):I thought 175hrs timeline will end on September while 350hrs will end on November.
So according to those timelines, I have to write development schedule too.
Daniel Rossberg (Apr 14 2022 at 16:46):Database Title [/path/to/the/file.g]. If this text is too long, you could write the title in the tab and have the file path as tool tip for it. In addition, you could have in the File menu (or somewhere else?) a Properties entry where one can set the database title.These are only small issues. Implementing only these wouldn't be enough for a GSoC project. You should look for at least one new CAD feature, like creating and modifying a pipe with the mouse. It can be something else, but you should aim for implementing a new concept for working with BRL-CAD models.
Because you plan to go with 175h, how about a small feature as placing and sizing new solids with the mouse?
Daniel Rossberg (Apr 14 2022 at 16:53):Added the medium size to the project idea.
Himanshu (Apr 14 2022 at 16:58):Daniel Rossberg said:
- I don't miss this alert box. In mged it signals that something happened. This shouldn't be necessary in arbalest because the GUI elements change according the opened database. An often used way to display a datasets title is to use

In addition, you could have in the File menu (or somewhere else?) a Properties entry where one can set the database title.- This would create space in the status bar for something else.
- Qt comes with an own frame work for help pages. And, arbalest aims for a GUI centered user interface.
- An arb7, etc. is in fact a (special) arb8 and arbalest was implemented very straight there. It would however be very useful to be able to create the other arb# there too, ideally with mouse support to place and resize them.
- The shortcuts should adapt to what's usual for CAD or modeler applications. But, there seem indeed only few shortcuts implemented in arbalest. I.e., we would probably need more there.
- Yes, creating other arb# with mouse support to place and resize them would be a meaningful feature.

Himanshu (Apr 14 2022 at 17:23):In mged, placing a new solid using mouse and resizing is there or not? I have to search for it to see how it works originally.

Yes, they are new for arbalest, but rather small and straight forward, not demonstrating a new concept for a GUI.

You can look at the mged tutorial for reference. But, I don't recommend to copy it. And, don't think of mged as the original. It's rather the reference (together with archer). Arbalest want's to introduce a new way of interacting with the geometry.

Now I remembered that using in we are able to create shape by giving size to the parameters.
Himanshu (Apr 14 2022 at 17:44):Is it like that? Instead of CUI, use mouse support to place and resize.
Himanshu (Apr 14 2022 at 19:45):I will look into it in the morning. I have written down bugs that I am going to fix and also extending support for coreinterface in my proposal. Only thing that is missing is adding at least an feature. I will check it out in morning for this new feature. By far I know we can create shapes by giving size using in which insert command.
Himanshu (Apr 15 2022 at 16:21):@Daniel Rossberg I have done an example. Is it like this? Desktop-2022.04.15-21.48.06.03.mp4
Daniel Rossberg (Apr 15 2022 at 16:38):This is how it works in mged. But you should not be tempted to copy from mged. Be creative!
E.g., how are other programs doing this? Some of them put handles on the objects which can be hold by the mouse and allow special actions (moving, resizing, rotating it), for example.
Mouse supported placing and sizing of new solids is one possibility for a new feature. Selecting objects with the mouse could be another. E.g., selecting an element in a ray-traced view and make it transparent, to see what's inside. Or, clicking on the model starts a ray-trace and returns a list of hits.
Be creative!!!

I am thinking of one way. Like first selecting an object through mouse by selecting an specific area.
Himanshu (Apr 15 2022 at 17:04):Then do operation like move and resizing.
Himanshu (Apr 15 2022 at 17:05):I will post an example now.

Here is an example that I have done in AutoCAD. Desktop-2022.04.15-23.01.41.04.mp4
Himanshu (Apr 15 2022 at 17:42):This is a feature where we can select an object and can resize them.
Himanshu (Apr 16 2022 at 21:09):I have a doubt. In rt-cubed/include/brlcad, all primitives headers are there. Let's take Arb8.h as consider. How Arb8.h here is different from arb8.h found in brlcad/include/rt/primitives? Are they same?
Himanshu (Apr 16 2022 at 21:10):@Daniel Rossberg How Arb8.h is extracting object nature from arb8.h?
Daniel Rossberg (Apr 17 2022 at 17:47):Did you looked into these files?
Himanshu (Apr 17 2022 at 17:49):Yes
Himanshu (Apr 17 2022 at 17:52):Today I added Pipe and BagOfTriangles to MainWindow.cpp to test it.
Himanshu (Apr 17 2022 at 17:53)::sweat_smile: I am able to give the object name too but not able to draw on screen.
Himanshu (Apr 17 2022 at 17:54):I will look later why they don't work.
Himanshu (Apr 17 2022 at 17:55):Currently I am writing milestones and timeline for the project. Hopefully I will send the draft for feedback tomorrow.
Daniel Rossberg (Apr 17 2022 at 17:55):I mean, opened them in and editor and read it.
Himanshu (Apr 17 2022 at 17:56):I am thinking to leave the project as Long so I will get time to research and implement the feature.
Himanshu (Apr 17 2022 at 17:58):Daniel Rossberg said:
I mean, opened them in and editor and read it.
Yeah, I had opened and read the code too. I tried to look into functions of both arb8.h and Arb8.h.
Daniel Rossberg (Apr 17 2022 at 18:00):The function names mainly describe what they are doing. From these descriptions, what do you think are the headers purpose?
Himanshu (Apr 17 2022 at 18:01):Looked into functions like rt_arb_centroid(), rt_arb_calc_points(), etc of arb8.h and tried to match with function found in Arb8.h like NumberOfVertices(), Point(), SetPoint().
Daniel Rossberg (Apr 17 2022 at 18:05):And, do they match?
Himanshu (Apr 17 2022 at 18:07):Daniel Rossberg said:
And, do they match?
I am not able to match it through function names. So may be I have not yet looked into .cpp files.
Himanshu (Apr 17 2022 at 18:08):I thought names are not similar too. So might be anything other.
Daniel Rossberg (Apr 17 2022 at 18:13):Looking at the function names should you give the answer: The headers of the core interface declare the interfaces for accessing the primitives, as expected. The headers in rt/primitives are utility functions which declare/export some useful higher level functions used ate different places in main BRL-CAD.

Hmm now I understand. So coreinterface still uses main BRL-CAD for some functions.
Himanshu (Apr 17 2022 at 18:24):I thought it to be single one rather than extracting from main BRL-CAD.
Himanshu (Apr 17 2022 at 18:25):my bad
Himanshu (Apr 17 2022 at 18:28):I thought every functionality of arb8.h have to be here in Arb8.h so that it will not use even a single functionality from main BRL-CAD.
Daniel Rossberg (Apr 17 2022 at 18:36):The "C++ core interface" is a thin layer on the BRL-CAD core.
Himanshu (Apr 18 2022 at 16:36):Since my proposal contains gif to show some examples that can't be viewed in pdf format. So here is the docs file format draft of my proposal. I am currently uploading in gsoc website.
Himanshu (Apr 18 2022 at 16:43):@Daniel Rossberg What topics I should include for this project?
Himanshu (Apr 18 2022 at 16:43):saw in gsoc
Daniel Rossberg (Apr 18 2022 at 16:44):BTW, the creation of arb5, arb6, tgc, etc. are implemented in the core interface. See the constructors.

Daniel Rossberg (Apr 18 2022 at 16:51):Choose the topics you think match best. Graphics sounds reasonable, maybe GUI too.

You should explicitly mention the program size (mdium/175h or large/350h) you apply too in your proposal.
Himanshu (Apr 18 2022 at 20:19):I found that a constructor in ellipsoid.h for sph is already there and also a sphere.h is created for sph.
Himanshu (Apr 18 2022 at 20:19):Are they same?
Himanshu (Apr 18 2022 at 20:21):btw both have different functions in use.
Himanshu (Apr 18 2022 at 20:54):Updated the document and sent proposal from gsoc website.
Daniel Rossberg (Apr 19 2022 at 13:46):Himanshu Sekhar Nayak said:

It's a bit confusing that both Ellipsoid and Sphere handle rt_ell_internal. But, ConstDatabase::Get (in ConstDatabase.cpp) and Database::Add (in Database.cpp) tell you that Ellipsoid is a C++ handle for the database objects with ID ID_ELL (3) and Sphere is a handle for objects with ID_SPH (10).
Himanshu (Apr 21 2022 at 14:19):Btw for creating a rectangle shape selection area using mouse support, I have found https://doc.qt.io/qt-5/qrubberband.html#:~:text=A%20QRubberBand%20can%20represent%20a,QRubberBand%20can%20represent%20a%20rectangle.
Himanshu (Apr 21 2022 at 14:19):Currently I learnt about QDialog, signals and slots and their functions too.
Himanshu (Apr 21 2022 at 15:40):https://doc.qt.io/qt-5/qrubberband.html
Himanshu (Apr 21 2022 at 15:44):I found another one and it looks picking an primitive https://doc.qt.io/qt-5/qtquick3d-picking-example.html

This can give you some ideas, but the example is based on a different geometric engine and a different kind of programming (QML).

Hmm QML : JavaScript
Himanshu (Apr 21 2022 at 16:29):I will look into it.
Himanshu (Apr 22 2022 at 18:14):I found a bug :beetle: Opening a new tab and closing it and having Quick Start tab opened, I am still able to create arb8 and also it shows properties and objects.
Himanshu (Apr 22 2022 at 19:06):@Daniel Rossberg Can I send a pull request? I have fixed a bug that I have mentioned above. I am asking because I don't know if the actual coding should start after the project gets selected or before. But anyways I want to fix the bug :innocent: :grinning_face_with_smiling_eyes:.
Himanshu (Apr 22 2022 at 19:21):Btw I have a doubt
Himanshu (Apr 22 2022 at 19:22):In MainWindow.h line no 53
// The ID of the active document.
int activeDocumentId = -1;
Himanshu (Apr 22 2022 at 19:23):Here activeDocumentId is counting number of tabs opened?
Himanshu (Apr 22 2022 at 19:30):hmm for each tab, it's giving an id number?
Himanshu (Apr 22 2022 at 19:33):What I found that even after new tab is closed and if Quick Start is not closed then still activeDocumentId is 0. So Create is able to function.
Himanshu (Apr 22 2022 at 19:38):I will look into this in morning. Late night here.

Same applies to Save and Save As too.
Himanshu (Apr 23 2022 at 15:01):I have also found that after the tab is removed, the [key, value] is not removed from the documents which is type of unordered_map.

Himanshu (Apr 28 2022 at 21:00):I pushed a new commit @Daniel Rossberg.
Himanshu (Apr 29 2022 at 15:28):@Daniel Rossberg I don't know if these functions like Relative scale, move, rotate are actually working or not? I didn't find any during testing. Is these are the functions that we are talking about to implement like move and scale?
Himanshu (Apr 29 2022 at 15:29):I found one
QMenu* editMenu = menuTitleBar->addMenu(tr("&Edit"));
QAction* relativeMoveAct = new QAction("Relative move selected object", this);
relativeMoveAct->setStatusTip(tr("Relative move selected object. Top objects cannot be moved."));
connect(relativeMoveAct, &QAction::triggered, this, [this](){
if (activeDocumentId == -1) return;
if (documents[activeDocumentId]->getObjectTreeWidget()->currentItem() == nullptr) return;
int objectId = documents[activeDocumentId]->getObjectTreeWidget()->currentItem()->data(0, Qt::UserRole).toInt();
MatrixTransformWidget * matrixTransformWidget = new MatrixTransformWidget(documents[activeDocumentId],objectId, MatrixTransformWidget::Translate);
});
editMenu->addAction(relativeMoveAct);
btw @Sean Have you looked into my proposal :sweat_smile: ? I am just curios if you have seen it or not. I had shown to Daniel. btw pdf doesn't show the gifs but here is the doc file that shows gifs proposal

You need a combination to use these functions. The transformation matrix is put into the object tree. But, I didn't found a way to confirm the input values :thinking:

Himanshu (May 06 2022 at 18:46):/me learning Models of Qt
Himanshu (May 09 2022 at 20:10):Finished Models and learnt QStringListModel, QFileSystemModel, QStandardItemModel with List, Table and Tree View and also know how the models are sync and extract data from a model. :grinning:
Himanshu (May 10 2022 at 20:59):The rt-cubed version uses the BRL-CAD libraries from the main installation during runtime while MOOSE doesn't. Sounds interesting. How I forgot about this :sad: ?
Sean (May 11 2022 at 20:09):@Himanshu Sekhar Nayak that's one of the more compelling aspects of the arbalest architecture, honestly. It's built strictly on top so there's no cheating or lazy coding even possible. It requires calling through API, properly layered and isolated. It's cool.
Daniel Rossberg (May 12 2022 at 17:12):MOOSE is a generalization of the Windows brlcad.dll. The goal is to get a shard library containing the complete BRL-CAD core, which can be distributed easily with all supported systems. In addition, it shall not be a "hack" but cleanly build based on a normal BRL-CAD installation.
Himanshu (May 12 2022 at 17:19):May be next time, this project will appear in gsoc? Anyways, I am interested for it. I will look into it in future.
Sean (May 12 2022 at 17:22):@Himanshu Sekhar Nayak "this project" meaning what? working on MOOSE?
Daniel Rossberg (May 12 2022 at 17:22):It would be interesting to port arbalest to MOOSE. This would avoid hacking rt-cubed, for example. This port would consist mainly in some renaming (e.g. header paths).
Himanshu (May 12 2022 at 17:23):Sean said:

So MOOSE will be independent and once it get's installed and compiled and it will never look back to libraries during runtime what rt-cubed does.
Daniel Rossberg (May 12 2022 at 17:28):MOOSE is liked with the static BRL-CAD libraries.
Himanshu (May 12 2022 at 17:29):That's cool I think and it will be faster in terms of performance right?
Sean (May 12 2022 at 17:31):That's an interesting nuanced perspective (static).. I hadn't really conceptualized it in terms of static vs dynamic. I think of it as clean C++ API on top of the C libs (i.e., rt^3) but compiled in a separate space so it can't reach into non-public API.
Daniel Rossberg (May 12 2022 at 17:32):Himanshu Sekhar Nayak said:
That's cool I think and it will be faster in terms of performance right?
Potentially yes, but it looks like that the overhead of having multiple dynamic bindings should not be overrated.
Sean (May 12 2022 at 17:32):I doubt performance will be a distinguishing feature, but yes it does put less burden on program start-up time as the linker doesn't have to resolve symbols.
Sean (May 12 2022 at 17:33):There's also a different memory footprint, as the dynamic linker will often not load until something is actually needed. So there's a tradeoff that will have different implications for different app needs.

One possible application in mind was the BRL-CAD backend for Freecad. They may have stronger requirements regarding their libraries (like Linux standard base).
Himanshu (May 12 2022 at 18:02):@Daniel Rossberg https://github.com/BRL-CAD/arbalest/pull/13#discussion_r870764258 What you think about this?
Himanshu (May 24 2022 at 04:59):So how should I proceed?
Sean (May 24 2022 at 15:00):@Himanshu Sekhar Nayak for most, this is the time to get fully set up and familiarized with the code and community, so you have an advantage there -- you're already familiar. Your mentor may have other setup tasks in mind, but one bit of setup that'd be useful would be compiling the latest brlcad repo with Qt enabled, familiarize yourself with how it's different. That way, you'd be able to at least be aware what is going on in those Qt modules that are being developed for other GUI integrations, and what's going on in Arbalest.
Himanshu (May 24 2022 at 15:12):Okay, I think I should clean up my workspace and build brlcad & arbalest again. Btw I saw that previous year students maintained a log for each day work. So should I do that this year too?

if (displayGrid->getDocument()->getDocumentId() != activeDocumentId) {
The outer if tests if it's a BRL-CAD database or not. If it's not, and if it wasn't reset yet (activeDocument = -1), then reset it now.

Sean (May 27 2022 at 04:36):Yes, that's to be expected. It wasn't designed using the GUI tool.
Daniel Rossberg (May 27 2022 at 10:58):We didn't want to use the code generator. I'm also in doubt that what Himanshu did can be created with the Composer.

Daniel Rossberg (May 27 2022 at 15:19):Sorry, you are right, it's called Qt Creator.
Himanshu (May 27 2022 at 18:28):Created a pr https://github.com/BRL-CAD/arbalest/pull/16 @Daniel Rossberg
Himanshu (May 27 2022 at 20:25):Updated my dev log and also raised an issue https://github.com/BRL-CAD/arbalest/issues/17

Nope, it is not fixed yet. Properties docks are not visible while switching tabs.
Himanshu (May 29 2022 at 16:36):@Daniel Rossberg Arbalest have special tool bar?
Himanshu (May 29 2022 at 17:00):btw should I add those icons to the menubar?
Himanshu (May 29 2022 at 17:04):but these icons are in black color and doesn't suit with violet.
Himanshu (May 29 2022 at 17:05):
Himanshu (May 29 2022 at 17:05):probably white icons can help?
Himanshu (May 29 2022 at 19:41):I am thinking to remove QPushButton completely in tool bar area and only keep DisplayGrid and Viewports.
Himanshu (May 29 2022 at 20:02):But still there will be duplicate code for DisplayGrid and ViewPorts. One thing can be done like keep QPushButton and remove QAction for DisplayGrid and ViewPorts. It looks good and helpful too.
Daniel Rossberg (May 30 2022 at 16:46):Himanshu Sekhar Nayak said:
Daniel Rossberg Arbalest have special tool bar?
The usual way would be to use a QToolBar object, e.g. from QMainWidget::addToolBar(). But, arbalest uses a QFrame with a QVBoxLayout for this purpose.
Daniel Rossberg (May 30 2022 at 16:51):You can assign an action to a QToolButton via setDefaultAction().
Himanshu (May 30 2022 at 17:05):Instead of using QPushButton, we can shift to QToolButton.
Himanshu (May 30 2022 at 17:06):So we have QToolBar and QVBoxLayout.
Himanshu (May 30 2022 at 17:07):I will look into it and will compare what will be best.
Daniel Rossberg (May 30 2022 at 17:08):I think, it's worth to give QToolButton a try. And of course, it need a different icon.
Himanshu (May 30 2022 at 17:09):Btw QVBoxLayout is like having items downward fashion right?
Himanshu (May 30 2022 at 17:10):Like this Screenshot-2022-05-30-224015.png
Daniel Rossberg (May 30 2022 at 17:11):Right, the V is for vertical, QHBoxLayout (QHBoxWidget) is the horizontal one.
Himanshu (May 30 2022 at 17:13):Daniel Rossberg said:
I think, it's worth to give QToolButton a try. And of course, it need a different icon.
Previous night, I was trying that QToolButton. And I agree that once QAction object for New is created then it can be used by QToolButton too right?
Daniel Rossberg (May 30 2022 at 17:15):I would expect it. The documentation and the Internet says it...
Himanshu (May 30 2022 at 17:15):Yep, I was searching on it and saw we can assign QAction to QToolButton.
Himanshu (May 30 2022 at 17:16):I have a doubt regarding GSoC timelines.

Himanshu (May 30 2022 at 17:17):It should be November right? Or google will extend it in future?
Daniel Rossberg (May 30 2022 at 17:21):So, you want Final Submission End Date: Monday, November 21?
Himanshu (Jun 01 2022 at 14:22):Created a new PR https://github.com/BRL-CAD/arbalest/pull/19
Himanshu (Jun 02 2022 at 16:47):@Daniel Rossberg Ahh... what a fool I used view in for all icons.

$Color-IconView : #0d7088;
$Color-IconRaytrace : #cf041b;
It can easily been overseen. I realized the different colors when I put the old and new version side-by-side, and looked for the reason.

Daniel Rossberg (Jun 02 2022 at 17:03):BTW, this method could be a way to recolor the icons for the menu too. Something like $Color-MenuIcon: #ffffff;.
Himanshu (Jun 02 2022 at 17:04):So we are adding icons to menu items?
Daniel Rossberg (Jun 02 2022 at 17:05):You could also have Color-MenuIconFile, Color-MenuIconView, and Color-MenuIconRaytrace. Try it out!
Daniel Rossberg (Jun 02 2022 at 17:05):Himanshu Sekhar Nayak said:

By adding the icon to the action.
Himanshu (Jun 02 2022 at 17:08):I will start my work from 6th June because I have an entrance exam on 4th June and tomorrow I will be travelling to a different state because the test center is not available where I live now.

Daniel Rossberg (Jun 02 2022 at 17:21):Have a good trip!
Himanshu (Jun 06 2022 at 15:17):@Daniel Rossberg Are we planning to add icons to QAction open, new, .... same like that I had done for QToolButton? I am bit confused to add icons to the menu or inside menu items?

I would give QAction::setIcon() a try. With an appropriate $Color-, of course.
Himanshu (Jun 07 2022 at 14:56):Added a new commit to the pr.
Himanshu (Jun 08 2022 at 07:01):@Daniel Rossberg To create a toggle button for ToggleGrid, I saw that using QCheckBox and adding icons ON/OFF we can do it. But I think we can achieve same using QToolButton by using QToolButton::pressed and QToolButton::released too.
Himanshu (Jun 08 2022 at 20:12):I created a new pr https://github.com/BRL-CAD/arbalest/pull/21. We can remove the color if you don't like it.
Daniel Rossberg (Jun 09 2022 at 17:55):I'm having a busy week. I hope to be able to test them at the weekend.
Himanshu (Jun 09 2022 at 17:56):No problem, take your time. :cowboy:
Himanshu (Jun 13 2022 at 12:34):@Daniel Rossberg Added a new pr and found some problems too. https://github.com/BRL-CAD/arbalest/pull/22

Sean (Jun 13 2022 at 14:46):Seems like a good idea for readability
Himanshu (Jun 13 2022 at 17:03):I haven't yet tried QAction::setCheckable(). Will do it now.
Himanshu (Jun 13 2022 at 17:24):After I add isCheckable to true. But the color shows Screenshot-2022-06-13-225345.png
Himanshu (Jun 13 2022 at 17:26):how this color is set?
Himanshu (Jun 13 2022 at 17:27):I can't find.
Daniel Rossberg (Jun 13 2022 at 17:32):I don't really know what you mean. I'm just testing it, and something strange happens. But, the QToolButton now has definitely a checked state.
Himanshu (Jun 13 2022 at 17:35):Daniel Rossberg said:
I don't really know what you mean. I'm just testing it, and something strange happens. But, the QToolButton now has definitely a checked state.
I removed setCheckable(true); from toggleGrid and added back to toggleGridAct->setCheckable(true);. Also I commented out connect that I have added in my pr. Then I run the program and click on that button and it becomes green.
Himanshu (Jun 13 2022 at 17:35):I can't find where this color property is set.
Daniel Rossberg (Jun 13 2022 at 17:38):Maybe, it's a default behavior. Can you control it with your #toolbarButton:checked { background-color: "$Color-ButtonHoverMask"; } line?
Himanshu (Jun 13 2022 at 17:39):Nope.
Himanshu (Jun 13 2022 at 17:39):Already tested it out but nothing I can see the result.
Himanshu (Jun 13 2022 at 17:39):Yes it may be a default behaviour.
Daniel Rossberg (Jun 13 2022 at 17:40):BTW, on my computer (Linux) the icon disappears and is replaced by the tool tip text. But, this text shows a nice toggle behavior.
Daniel Rossberg (Jun 13 2022 at 17:41):Well, something you can test out tomorrow.
Himanshu (Jun 13 2022 at 17:41):I will test it and will you tell you if something I find. :computer:
Himanshu (Jun 14 2022 at 14:07):@Daniel Rossberg I found that the icon becomes green due to the icon that I had set for QAction in toogleGridAct. So when I click on the tool button of toggle grid, it swaps with the color that had been set for icon in QAction.
Himanshu (Jun 14 2022 at 14:31):So I commented out setIcon of QToolButton for toggleGrid and ran the program. I found that the the setIcon for QAction is acting default for QToolButton too. The icon for QAction is already there for QToolButton too which means setDefaultAction is playing a part here.
Himanshu (Jun 14 2022 at 14:37):So one now I am proposing that if we set icons for QAction for all items in menu bar then the icons will be already be present for QToolButton too. Should we do that?
Daniel Rossberg (Jun 14 2022 at 17:40):Hmm, not sure if it helps, but it may good to know: Look at the documentation of QIcon. You can set there multiple pixmaps for multiple purposes. I.e., in Qt an icon isn't just one image.

Hmm the icons that I have added for QAction for files of items in menu bar will not suit the color to fit in tool bar area, I think.
Himanshu (Jun 15 2022 at 15:47):I am taking a day off today.
Himanshu (Jun 16 2022 at 15:22):I have commented out all setIcon for QToolButton and let them behave according to setDefaultAction and it looks this. Screenshot-2022-06-16-205231.png
Himanshu (Jun 16 2022 at 15:23):For files the color is not suitable and looks not good.
Daniel Rossberg (Jun 16 2022 at 16:13):Therefore, which color do you propose?
Himanshu (Jun 16 2022 at 16:18):I haven't decided it yet. I have to choose a color that will best fit in menu bar and in tool bar too. I am now looking into it.
Himanshu (Jun 16 2022 at 19:55):Pushed a new commit regarding that and solved merge conflicts.
Himanshu (Jun 16 2022 at 19:56):And now it looks like this. check.png
Himanshu (Jun 16 2022 at 19:57):I chosen a color which both suits light and dark areas.
Himanshu (Jun 16 2022 at 19:58):I also found a way that is mentioned in docs too. https://doc.qt.io/qt-6/qicon.html#making-classes-that-use-qicon
Himanshu (Jun 17 2022 at 14:53):@Daniel Rossberg Is there any closeEvent()? So that we can handle close successfully like when we close we can see if a document is opened or not and also it is saved or not.
Himanshu (Jun 18 2022 at 07:01):I found there is no closeEvent().
Himanshu (Jun 18 2022 at 07:35):It should check if current document is edited and not saved then the closeEvent() should notify to save it or close it, like that.
Himanshu (Jun 18 2022 at 17:36):Btw what event propagation in qt really do? I only came to know through by writing an example if I have two classes ParentButton and ChildButton. ParentButton inherits QPushButton and ChildButton inherits ParentButton. In ParentButton class I have added an override function name ParentButton::mousePressEvent(QMouseEvent *event) and inside this function definition I called QPushButton::mousePressEvent(event); while in 'ChildButton' class I have added ChildButton::mousePressEvent(QMouseEvent *event) and inside this function definition I have added ParentButton::mousePressEvent(event);.
Himanshu (Jun 18 2022 at 17:36):Then in widget.cpp I wrote
Widget::Widget(QWidget *parent)
: QWidget(parent)
, ui(new Ui::Widget)
{
ui->setupUi(this);
ChildButton *button {new ChildButton(this)};
button->setText("Child Button");
connect(button, &ChildButton::clicked, [=](){
qDebug() << "Button clicked";
});
ui->verticalLayout->addWidget(button);
}
And when I run this program I can clearly see the output of the program using qDegug()
Child button mousePressEvent called
Parent button mousePressEvent called
Button clicked
But if I comment out ParentButton::mousePressEvent(event); then connect doesn't work. Why? Slot doesn't respond it. Why?
Himanshu (Jun 18 2022 at 17:44):Ultimately this ChildButton is not going to work if I comment it out.
Himanshu (Jun 19 2022 at 17:37):Created a new commit where I selected a suitable color for both light and dark theme.
Himanshu (Jun 20 2022 at 14:31):btw where I should start looking for to add mouse support using qt? Any references?
Himanshu (Jun 20 2022 at 14:32):Currently I am looking to mouse events.

Daniel Rossberg Is there any
closeEvent()? So that we can handle close successfully like when we close we can see if a document is opened or not and also it is saved or not.
The QWidget class has a protected function closeEvent() which can be redefined to handle close events correctly.
Daniel Rossberg (Jun 20 2022 at 17:25):While testing your latest version of #21 I learned that it's not a good idea to have the same colors for the menu and tool buttons. However, you can give an own color to the tool buttons with setIcon.
Then, I saw that a light color looks good in the menus, as long as you don't touch it with a mouse. Then, the background color changes to white. This can be handled by code like this:
QIcon newActIcon;
newActIcon.addPixmap(QPixmap::fromImage(coloredIcon(":/icons/sharp_note_add_black_48dp.png", "$Color-MenuText")), QIcon::Normal);
newActIcon.addPixmap(QPixmap::fromImage(coloredIcon(":/icons/sharp_note_add_black_48dp.png", "$Color-Menu")), QIcon::Active);
newAct->setIcon(newActIcon);
As I already said, in Qt an icon isn't just one image.
Daniel Rossberg (Jun 20 2022 at 17:26):Himanshu Sekhar Nayak said:

You probably have to reimplement one or more of QWidget's protected mouse~Event() functions.

Himanshu (Jun 22 2022 at 15:19):Btw should I mention or credit the icons that I use for arbalest? Those icons I used are free.
Himanshu (Jun 23 2022 at 11:09):Found a bug. After closing the tab. The toolbutton are no longer there. Here what is missing. Screenshot-73.png
Himanshu (Jun 23 2022 at 11:09):The toolbutton supposed to be there right even after there is no tabs or documents open?
Himanshu (Jun 23 2022 at 11:12):MainWindow::tabCloseRequested(const int i) and MainWindow::closeButtonPressed() are not handled if a document is open and there is unsaved changes. And closing the tab should open a dialog and ask to save it. Save goes for closeButtonPressed if the whole application is going to be closed then it should check if there any unsaved changes that are not saved yet.
Himanshu (Jun 23 2022 at 11:14):Is there gonna be any difference if we should use closeEvent() instead of closeButtonPressed()? We can override closeEvent and add the implementation on how to handle the close if there are any unsaved changes?
Himanshu (Jun 23 2022 at 18:37):Pushed a commit where I added Save As to toolbutton and added icons for rest of toolbuttons. Only thing broken is toolGridButton. Because it should behave as pressed if a document is open and the background color should become grey but for now without any document open, it can turn grey if it is in pressed state.
Himanshu (Jun 23 2022 at 18:37):Will work on it tomorrow.
Himanshu (Jun 24 2022 at 14:16):I have upcoming exams from 27-29 June. I may not contribute during those days. I will resume from 29 June.
Himanshu (Jun 24 2022 at 18:55):I just saw https://doc.qt.io/qt-6/qaction.html#qaction-in-widget-applications and thought to give something like that to our code. Btw how it looks:
QIcon newActIcon;
newActIcon.addPixmap(QPixmap::fromImage(coloredIcon(":/icons/sharp_note_add_black_48dp.png", "$Color-MenuIconFile")), QIcon::Normal);
newActIcon.addPixmap(QPixmap::fromImage(coloredIcon(":/icons/sharp_note_add_black_48dp.png", "$Color-Menu")), QIcon::Active);
QAction* newAct = new QAction(newActIcon, tr("&New"), this);
newAct->setShortcuts(QKeySequence::New);
newAct->setStatusTip(tr("New .g file"));
connect(newAct, &QAction::triggered, this, &MainWindow::newFile);
fileMenu->addAction(newAct);
Everything looks same. Only thing is that I directly passed it to the constructor instead of setIcon but looks clean. @Daniel Rossberg
Himanshu (Jun 24 2022 at 19:43):Btw I implemented toggle feature for QAction *toggleGridAct like this and it's working simultaneously with toggleGridButton too. Here is a look:
connect(toggleGridAct, &QAction::triggered, this, [=](){
if (toggleGridAct->isChecked()) {
if (activeDocumentId == -1) {
toggleGridAct->setChecked(false);
return;
}
}
documents[activeDocumentId]->getDisplayGrid()->getActiveDisplay()->gridEnabled =
!documents[activeDocumentId]->getDisplayGrid()->getActiveDisplay()->gridEnabled;
documents[activeDocumentId]->getDisplayGrid()->getActiveDisplay()->forceRerenderFrame();
});

MainWindow is a QMainWindow, which doesn't have a tabCloseRequested() method. I.e., if you implement one, it will never be called (you don't overwrite the default one because there is no such function). Only QTabBar and QTabWidget have tabCloseRequested() methods.
For catching closing of the application look at the Qt documentation at QWidget::closeEvent():
void MainWindow::closeEvent(QCloseEvent *event)
{
if (maybeSave()) {
writeSettings();
event->accept();
} else {
event->ignore();
}
}

Daniel Rossberg (Jun 27 2022 at 17:49):@Sean Do we have icon sets? I looked at https://brlcad.org/gci/, but could find CAD specific icons only, nothing for load/save/new document/etc..
Sean (Jun 28 2022 at 16:41):@Daniel Rossberg yes and no. I have some of the icon sets summarized at https://brlcad.org/design/ under 'icons' for app and web. I only uploaded the overviews, but the complete data sets are under gci/data. There's also a fair bit of GUI concepts under https://brlcad.org/design/gui/ including a few new ones I recently added from 2017 gci. They should all be fair game.
Sean (Jun 28 2022 at 16:56):Here are a handful of good open source icon repositories I've come across:
https://fonts.google.com/icons (apache)
https://remixicon.com (apache)
https://iconoir.com (mit)
https://materialdesignicons.com (mostly apache, see https://github.com/Templarian/MaterialDesign)
https://icons.mono.company (mit)
https://feathericons.com (mit)
Himanshu (Jun 29 2022 at 15:02):Thanks @Sean for the resources. Btw I like the icons provided by Google.
Himanshu (Jun 29 2022 at 15:03):Btw I pushed a new commit too.

Daniel Rossberg (Jun 29 2022 at 17:56):Not exactly. They write "If the Work includes a "NOTICE" text file...". Arbalest does not. But, the License file should be updated. And maybe mentioned which files are under Apache 2.0 license.

isModified()to check if there is unsaved changed which is a part ofQLineEdit.
That's the point: How do you know if the database was modified? You won't get it for free.
Himanshu (Jul 03 2022 at 17:10):Looks likes this is a feature too like mouse feature.
Himanshu (Jul 03 2022 at 19:14):Okay for now I have some things to do before I start implementing save feature.
Free memory as soon as I close the tab instead of eating up all memory even if the tabs are already closed through GUI. The current scenario of this thing is that in unordered_map all documents are destroyed after the application is closed. Instead of this, we should free memory as soon as the tab gets closed.
Currently I don't how the data is being saved in database. By far I only came to know how a file is currently saving the data:
bool MainWindow::saveFile(const QString& filePath) {
return documents[activeDocumentId]->getDatabase()->Save(filePath.toUtf8().data());
}
I need to know how getDatabase()->Save(filePath.toUtf8().data()) is actually being saved in a database. I have found Database.h and MemoryDatabase.h and need to see how this working on to save a file. Without knowing how these are working, I can't know what to do for unsaved changes.
isModified() to check if the document have any unsaved changes like this:bool MainWindow::saveFile(const QString& filePath) {
if (!isModified()) {
return false;
}
return documents[activeDocumentId]->getDatabase()->Save(filePath.toUtf8().data());
}
Taking day off today for tomorrow's one and only entrance examination.
Daniel Rossberg (Jul 04 2022 at 17:02):Something like this. You need a flag, which tells you if the database was modified. Any modifying function had to set it, and save() (for example) has to reset it.
Ideally, the save button isn't available, if the database wasn't modified.
Himanshu (Jul 06 2022 at 17:35):Working on to free memory as soon as the tab gets closed.
Himanshu (Jul 07 2022 at 18:50):Added new PR https://github.com/BRL-CAD/arbalest/pull/24

Thanks @Sadeep Darshana, I am currently looking into how to save the unsaved changes of a .g file.
Himanshu (Jul 09 2022 at 12:32):@Sadeep Darshana How's about the icons that are added? https://github.com/BRL-CAD/arbalest/pull/21
Himanshu (Jul 09 2022 at 16:03):@Sadeep Darshana Meanwhile also have a look here https://github.com/BRL-CAD/arbalest/issues/15. So far I am able to know that after selecting an object from object tree, documents[activeDocumentId]->getProperties()->bindObject(objectId); helps in creating properties and show values. But if I switched to other document where the object is already selected then it doesn't show the properties. Either it is not visible or something idk?
Himanshu (Jul 09 2022 at 18:48):@Daniel Rossberg while closing tabs, the memory is being freed. But I saw in task manager and also in vs while debugging but it doesn't show the memory being reduced of what it is being allocated. Is that right way to see?
Daniel Rossberg (Jul 09 2022 at 18:56):The memory assigned to the process can stay the same, if only a small amount is freed (which is the case for the empty in-memory database in your tests). The memory is kept in store by the C library memory management.
Himanshu (Jul 10 2022 at 11:35):@Daniel Rossberg okay looks like I found what have been causing this problem for switching tabs where it doesn't show properties of the selected object from objects docks.
Himanshu (Jul 10 2022 at 11:43):In Properties.cpp line 28 void Properties::bindObject(const int objectId) {} where it sets the values for properties. Here is the function:
void Properties::bindObject(const int objectId) {
this->fullPath = document.getObjectTree()->getFullPathMap()[objectId];
this->name = fullPath.split("/").last();
fullPathWidget->setText(QString(fullPath).replace("/"," / "));
static BRLCAD::Object* object = nullptr;
delete object;
object = document.getDatabase()->Get(fullPath.toUtf8().data());
objectType = QString(object->Type());
static TypeSpecificProperties * current = nullptr;
delete current;
current = new TypeSpecificProperties(document, object, objectId);
typeSpecificPropertiesArea->addWidget(current);
QString nameType = "<font color='$Color-PropertiesObjectNameText'>"+name+"</font><font color='$Color-DefaultFontColor'> ( "
"<font color='$Color-PropertiesObjectTypeText'>"+breakStringAtCaps(objectType)+"</font><font color='$Color-DefaultFontColor'> )";
nameWidget->setText(Globals::theme->process(nameType));
}
Here BRLCAD::Object* object stores the values of the selected object of the current document and if I switched to another tab or document then object still stores the values of the previous selected object from objects dock.
Himanshu (Jul 10 2022 at 12:09):Main Problem lies here:
static TypeSpecificProperties * current = nullptr;
delete current;
current = new TypeSpecificProperties(document, object, objectId);
typeSpecificPropertiesArea->addWidget(current);
Since it is static so it only retains the values when bindObject is called for an selected object from Objects dock.

I started with looking at the logic: In maybeSave() you iterate over the open files, but in closeEvent(), you call saveAsFileDialog(), which saves the active document only, which may even be unmodified. This doesn't look right.

I only completed maybeSave() but never looked to saveAsFileDialog() which is used in closeEvent(). I wrote saveAsFileDialog() when I had not implemented maybeSave() and hadn't thought about it so more.
Himanshu (Jul 18 2022 at 18:29):Btw, here is the new commit I added https://github.com/BRL-CAD/arbalest/pull/23/commits/f7a782f8aa58ae15ee1f9dac7c704a7d249dbc19
Daniel Rossberg (Jul 19 2022 at 17:50):Hmm, where is the "save file" there? Think about the desired behavior first! How should this feature work?
BTW, don't make it too complicated, e.g. by having two buttons for not saving.
Why not QMessageBox::question()?
Himanshu (Jul 23 2022 at 18:21):@Daniel Rossberg What will be the behavior if the user press cancel for unsaved changes? 1. Close the application 2. Don't close the application and allow user to modify the document ?
Himanshu (Jul 23 2022 at 19:54):Added new commit but I don't know what I should do for if the user press cancel.
Daniel Rossberg (Jul 24 2022 at 18:49):You need 3 buttons: "save", "don't save", and "abort". The first one saves the document and proceeds to the next one. The second doesn't save and proceeds to the next one. The last one aborts the procedure and arbalest won't close.
Himanshu (Jul 25 2022 at 14:27):During execution I got some warnings.
QObject::connect: No such signal QAction::QAction::triggered() in C:\Users\Himanshu\Desktop\Workspace\rt-cubed\src\arbalest\src\gui\MainWindow.cpp:124
QObject::connect: No such signal QAction::QAction::triggered() in C:\Users\Himanshu\Desktop\Workspace\rt-cubed\src\arbalest\src\gui\MainWindow.cpp:133
Currently,
124 connect(saveAct, SIGNAL(QAction::triggered()), this, SLOT(MainWindow::saveFileDefaultPath()));
133 connect(saveAsAct, SIGNAL(QAction::triggered()), this, SLOT(MainWindow::saveAsFileDialog()));
Btw should I ignore these? Btw I solved using,
124 connect(saveAct, SIGNAL(triggered()), this, SLOT(saveFileDefaultPath()));
133 connect(saveAsAct, SIGNAL(triggered()), this, SLOT(saveAsFileDialog()));
@Daniel Rossberg but it is less informative I think?
Daniel Rossberg (Jul 25 2022 at 17:03):It depneds, if you are using the SIGNAL and SLOT macros or not. I.e., connect(saveAct, &QAction::triggered, this, &MainWindow::saveFileDefaultPath); should work too (using function pointers).
And no, you shouldn't ignore these warnings ;)
Himanshu (Jul 25 2022 at 17:12):@Daniel Rossberg I got something when I am searching in stack overflow.
Himanshu (Jul 25 2022 at 17:12):/me Today's lesson is: do not overload your signals and slots in Qt!
Himanshu (Jul 25 2022 at 17:13):I used signal and slot macros since there are overloading functions.
Himanshu (Jul 25 2022 at 17:14):Btw I added three buttons but from user's perspective there should be abort button or cancel?
Himanshu (Jul 25 2022 at 17:15):Found here https://stackoverflow.com/questions/16794695/connecting-overloaded-signals-and-slots-in-qt-5
Himanshu (Jul 25 2022 at 17:16):What I found that we can use static_cast and qOverload too.
Himanshu (Jul 25 2022 at 17:19):But qOverload requires Qt 5.7
Daniel Rossberg (Jul 25 2022 at 17:24):Or, you could give the save file functions different names.
Daniel Rossberg (Jul 25 2022 at 17:26):Himanshu Sekhar Nayak said:

I would say "Cancel".

Daniel Rossberg (Jul 25 2022 at 17:30):You can work around this with static_cast or avoid it with not using same function names. It's your choice.

Himanshu (Jul 31 2022 at 07:15):@Daniel Rossberg Should we use ConstDatabase for sure? I saw it is for read-only. https://brlcad.org/wiki/BRL-CAD%27s_core_C%2B%2B_interface
Daniel Rossberg (Jul 31 2022 at 14:18):? Where? Arbalest is for modifying databases too. However, MemoryDatabase is derived from Database, which is derived from ConstDatabase. I.e., if you want to return a database handle, where you can be sure that the receiver isn't able to modify it, you can declare it as ConstDatabase.
Himanshu (Jul 31 2022 at 14:21):I made some progress by changing it to BRLCAD::ConstDatabase and still there are some conversion left to remove all errors reported during conversion.
Himanshu (Jul 31 2022 at 14:22):During conversion, I visited back to the article and saw it is for read-only.
Himanshu (Jul 31 2022 at 14:22):Anyways, I understood now.
Daniel Rossberg (Jul 31 2022 at 14:22):You mean Document::getDatabase()?
Himanshu (Jul 31 2022 at 14:23):yup
Daniel Rossberg (Jul 31 2022 at 14:25):That should be possible: By changing the return type to ConstDatabase you make sure that the calling function cannot modify it.
Daniel Rossberg (Jul 31 2022 at 14:29):It follows the usual const - non-const logic: If a function requires a const value, you can put in a non-const too, but not vice versa.
Himanshu (Jul 31 2022 at 15:02):documents[activeDocumentId]->getDatabase()->Add(*object);
Since there is no Add() in ConstDatabase and also for Save. Should I add those to ConstDatabase class?
Daniel Rossberg (Jul 31 2022 at 15:22):Definitely No! A const value cannot be modified. Didn't you know?
But, you can add an Add() and Save() method to the Documentclass, which take care for the modified flag.
Himanshu (Jul 31 2022 at 16:25):Daniel Rossberg said:

Okay I will add those to Document class.
Himanshu (Jul 31 2022 at 16:26):We can add the LICENSE to the about window.

Himanshu (Jul 31 2022 at 16:55):Added license to aboutwindow.cpp https://github.com/BRL-CAD/arbalest/pull/28
Himanshu (Aug 02 2022 at 17:19):@Daniel Rossberg Made some progress by adding Add and Save to Document and publicly inherited Database to Document because rt_wdb* m_wdbp; in Database is used in Add and Save. So moving Add and Save to Document to make sure it works.
But some of the problems that arises:
C++ object of abstract class type Document is not allowed: pure virtual function BRLCAD::Database::Load has no overrider
So looks like we have to override Load in Document.
torus->Internal() is not accessible. Need a fix for that. Daniel Rossberg (Aug 03 2022 at 17:44):I'm not sure what you are doing there. The Document class has a member variable database which is a BRLCAD::Database.
Himanshu (Aug 03 2022 at 17:45):Daniel Rossberg said:

BRLCAD::MemoryDatabase *database; This one?
Himanshu (Aug 03 2022 at 17:46):I added Add and Save to Document.
bool Add(const BRLCAD::Object& object);
bool Save(const char* fileName);
OK, that should be easy.
Himanshu (Aug 03 2022 at 17:49):But Add throws errors related to m_wdbp is not defined. So I inherited BRLCAD::Database to Document so that it will be visible.
Daniel Rossberg (Aug 03 2022 at 17:50):??? What's your code?
Daniel Rossberg (Aug 03 2022 at 17:51):paste your Document::Add() method here

?

Himanshu (Aug 03 2022 at 18:12):Daniel Rossberg said:

Okay I added those what you have suggested. May be database is here of MemoryDatabase and we need type of ConstDatabase to make sure calling function do not modify it?
Daniel Rossberg (Aug 04 2022 at 16:38):No, that's not it. Add() modifies the database. That's its purpose. ConstDatabase cannot have an add.
The reason for my doubt was that the code doesn't contain a check for NULL. But, Document won't work without a correct initialized database member. I.e., with a NULL database we won't get so far to call Add().
However, you should set the modified flag there, if you have it.

Himanshu (Aug 05 2022 at 20:09):Also I made sure that saveFile() should not save file unnecessarily if there is no modification in the document and tested it too.

Himanshu (Aug 06 2022 at 17:27):One thing that I missed is that we have implemented maybeSave() for application close and we missed for if a document is going to close then it should also for unsaved changes.
Himanshu (Aug 06 2022 at 17:38):And what buttons we should expect for one single document if there are any unsaved changes and going to be closed? Like Save, Discard or Don't Save and Cancel.
Himanshu (Aug 06 2022 at 19:39):Pushed a new commit where it checks if there is any object in the document before it start to ray trace.

Himanshu (Aug 12 2022 at 17:02):@Daniel Rossberg I am thinking to refactor maybeSave () so that tabCloseRequested() can also pass documentId to maybeSave()
Daniel Rossberg (Aug 12 2022 at 17:06):Regarding more mouse actions, here an idea: This can be handled by moving the event filter stuff (see MainWindow::eventFilter()) in an own class hierarchy. I.e. having a base class for all the actions
class MouseAction : public QObject {
Q_OBJECT
public:
virtual ~MouseAction(void);
signals:
void Done(MouseAction* myself);
protected:
QObject* m_watched;
MouseAction(QObject* watched,
...);
virtual bool QObject::eventFilter(QObject *watched,
QEvent *event);
private slots:
void WatchedDestroyed(QObject* watched);
};
and derive the specific actions from it
class ZoomInMouseAction : public MouseAction {};
class ZoomOutMouseAction : public MouseAction {};
class RotateMouseAction : public MouseAction {};
class MoveMouseAction : public MouseAction {};
...
They have to be instantiated if the corresponding button was pressed
MainWindow::MainWindow() : m_mouseAction(0) {}
void MainWindow::XButtonAction(void) {
if (m_mouseAction != nullptr)
delete m_mouseAction;
m_mouseAction = new XMouseAction();
installEventFilter(m_mouseAction);
}
(All code here has to be considered as pseudo-code. All names are arbitrary.)

Himanshu (Aug 15 2022 at 17:15):@Daniel Rossberg Added default parameter cancel to maybeSave(). Also I have added blue color to the heading of the dialog box text. See if you like it. Capture.PNG
Himanshu (Aug 17 2022 at 18:06):@Daniel Rossberg changing BRLCAD::MemoryDatabase to BRLCAD::ConstDatabase have some points that I have noted which are:
getBRLCADObject() in Utils.h so I have modified to only 2 args:inline void getBRLCADObject(BRLCAD::MemoryDatabase *database, const QString& objectName,const std::function<void(BRLCAD::Object&)>& func){
BRLCADObjectCallback callback(func);
database->Get(objectName.toUtf8(), callback);
}
Now
inline void getBRLCADObject(BRLCAD::ConstDatabase *database, const QString& objectName){
database->Get(objectName.toUtf8());
}
Since class BRLCADObjectCallback inherits BRLCAD::Database::ObjectCallback where virtual void operator()(const Object& object) = 0; it is a pure virtual function and it has been override in class BRLCADObjectCallback. But what I have changed works with no more errors. Only problem is that to keep const std::function<void(BRLCAD::Object&)>& func or not but I saw it has been used as lambda function.
Daniel Rossberg (Aug 18 2022 at 08:23):Well, this call-back function isbthe whole point on getBRLCADObject(). You version does nothing now. How about moving the getBRLCADObject() to the Document class and setting the modified flag there?
Himanshu (Aug 19 2022 at 19:22):@Daniel Rossberg Moved getBRLCADObject() inside Document class and the problem is that database->Get() not accepting BRLCADObjectCallback object because it inherits BRLCAD::Database::ObjectCallback. So I modified to BRLCAD::ConstDatabase::ObjectCallback and override the () operator where the arg for () is const BRLCAD::Object& object. Now it accepts but main problem is:
inline explicit BRLCADObjectCallback(std::function<void(BRLCAD::Object&)> func): func(std::move(func)){}
So I added const here too and also where it is declared privately. But now it is leading to more const errors.

It was accepting but when I changed to ConstDatabase for getDatabase() then the problem occurs.

Himanshu (Aug 24 2022 at 17:12):Then database->Get(objectName.toUtf8(), callback); didn't work for ConstDatabase.

Hmm, at first glance, it doesn't look good. Why doesn't
database->Get()accept aBRLCAD::Database::ObjectCallbackobject?It was accepting but when I changed to
ConstDatabaseforgetDatabase()then the problem occurs.
??? Can you please show me your code?
Himanshu (Aug 24 2022 at 17:18): BRLCAD::ConstDatabase* getDatabase() const
{
return database;
}
inline void getBRLCADObject(BRLCAD::ConstDatabase *database, const QString& objectName,const std::function<void(BRLCAD::Object&)>& func){

}
Didn't you want to move getBRLCADObject() to the Document class?
Himanshu (Aug 24 2022 at 17:20):I have shifted but still same issue.
Daniel Rossberg (Aug 24 2022 at 17:21):That's the point: You have not. There is no Document::getBRLCADObject() method.
Himanshu (Aug 24 2022 at 17:25):Working on it.
Himanshu (Aug 24 2022 at 17:28):@Daniel Rossberg In TypeSpecificProperties.cpp we can see in line 60-69:
connect(hasColorCheck,&QCheckBox::stateChanged,[this,objectId](int newState){
getBRLCADObject(this->document.getDatabase(),this->document.getObjectTree()->getFullPathMap()[objectId],[newState](BRLCAD::Object &object){
if(newState == Qt::CheckState::Checked){
dynamic_cast<BRLCAD::Combination&>(object).SetHasColor(true);
}
else {
dynamic_cast<BRLCAD::Combination&>(object).SetHasColor(false);
}
});
});
but how we are going to instantiate a Document class to access getBRLCADObject in lambda function and document class has no default constructor?
Himanshu (Aug 24 2022 at 17:33):oops
Himanshu (Aug 24 2022 at 17:33):I found that
Himanshu (Aug 24 2022 at 17:34):We need to capture document object in a capture list so that it can access getBRLCADObject

Noob here and how on earth I am not able to see there is already a document object. :grimacing:
Himanshu (Aug 24 2022 at 17:46):Okay modified to ConstDatabase that I have forgot.

No, we need the BRLCAD::Database::ObjectCallback. Only this can modify the object. However, did you noticed the modified = true; in my code example?

Himanshu (Aug 26 2022 at 14:43):@Daniel Rossberg Do we need this line anymore? Line 77 src/gui/MatrixTransformWidget.cpp
document->modifyObjectNoSet(document->getObjectTree()->getParent()[childObjectId]);
I removed this line after removing modifyObjectNoSet().
Daniel Rossberg (Aug 26 2022 at 15:06):Yes and no. The purpose of this function is to mark objects as changed for redrawing (geometryRenderer). This should however done more automatically whenever modified = true is set.
Himanshu (Aug 26 2022 at 15:12):So this function redraws geometryRenderer
Daniel Rossberg (Aug 26 2022 at 15:14):No. Who redraws?
Himanshu (Aug 26 2022 at 15:15):geometryRenderer->refreshForVisibilityAndSolidChanges(); this one
Himanshu (Aug 26 2022 at 15:17):This function works if the user selected relative scale or move or rotate and then it refresh the screen with new ones?
Daniel Rossberg (Aug 26 2022 at 15:19):Well, somehow the geometryRenderer instance :wink:
It gets the changed objects known (geometryRenderer->clearObject(objectId)) and does a refresh at the end (geometryRenderer->refreshForVisibilityAndSolidChanges()).
Himanshu (Aug 26 2022 at 15:34):I have added a base class to start with mouse action and will add more mouse action derived classes. Meanwhile, I also found two issues which leads to crash of program.
Himanshu (Aug 26 2022 at 15:35):BTW, we can't have object names empty. right?
Himanshu (Aug 26 2022 at 15:35):this things crash the program
Himanshu (Aug 26 2022 at 15:45):We can have a check if the user press ok and with string and then proceed otherwise if the user press cancel then no need to proceed. Otherwise this problem crash the program.
Daniel Rossberg (Aug 26 2022 at 15:52):Just checking the C++ interface. One point is that every object has a IsValid() method. This should check the name as well, but does it for a few types only :thinking:
Daniel Rossberg (Aug 26 2022 at 15:53):BTW, where does it crash?
Himanshu (Aug 26 2022 at 15:58):Daniel Rossberg said:
BTW, where does it crash?
Do not provide any name to the object of any primitive and in Object dock you can see there is a object with no name and try to click on it which leads to crash of the program.
Daniel Rossberg (Aug 26 2022 at 16:02):That's the "how to reproduce". But it was helpful too. The "where" is src/gui/Properties.cpp:33. object is probably invalid.
Himanshu (Aug 26 2022 at 16:22):Daniel Rossberg said:

IsValid()method. This should check the name as well, but does it for a few types only :thinking:
I can't find IsValid() in arbalest.
Daniel Rossberg (Aug 26 2022 at 16:27):It's not used there. It is a method of BRLCAD::Object, which checks if the object is okay.
Himanshu (Aug 26 2022 at 16:46):This one virtual bool IsValid(void) const = 0; inside Object.h.
Daniel Rossberg (Aug 26 2022 at 16:47):Yes. It's implemented in the derived classes.
Himanshu (Aug 26 2022 at 16:47):Daniel Rossberg said:
Yes. It's implemented in the derived classes.
For every primitive right?
Himanshu (Aug 26 2022 at 16:51):/me going for dinner now
Daniel Rossberg (Aug 26 2022 at 16:52):Well, now: yes. But wasn't before.
Himanshu (Aug 27 2022 at 15:23):@Daniel Rossberg I am thinking to do implement something like this.
bool ok;
QString name = QInputDialog::getText(this,tr("Object Name"), tr("Enter object name"), QLineEdit::Normal, "", &ok);
if (ok && !name.isEmpty()) {
object->SetName(name.toUtf8());
}
else {
return;
}
Hmm, without any feedback to the user?
QInputDialog::getText() is used 11 times in MainWindow. I.e., you should think about writing a function for it. How shall this function look like? It needs somehow two results: The new name and a flag if "Cancel" was hit. In this case, no primitive should be created.

So what I have thought like is that ....
ok without giving names then it should prompt to enter name. Daniel Rossberg (Aug 29 2022 at 16:37):You may need this function at other places too, e.g. to change an object name. Therefore, putting it at Utils?
Himanshu (Aug 30 2022 at 16:00):@Daniel Rossberg Changes-On-0e7832.patch I have done something like this but I have not added feedback to the user.
Himanshu (Aug 30 2022 at 16:01):Prompt a messagebox to the user?
Daniel Rossberg (Aug 30 2022 at 17:25):Something like: If Cancel was pressed, then isValidObjectName() returns false. If name is invalid, show a message box and run QInputDialog::getText() again.
BTW, isValidObjectName() is a bad function name, because it doesn't describe what this function does. getObjectNameFromUser() would be better.
Himanshu (Aug 31 2022 at 05:32):Here is the pr: https://github.com/BRL-CAD/arbalest/pull/36 @Daniel Rossberg
Himanshu (Sep 01 2022 at 15:27):https://github.com/BRL-CAD/arbalest/issues/35 BTW, different primitives having same name is not a good idea, I think?
Daniel Rossberg (Sep 01 2022 at 16:30):That's right. The objects are uniquely referenced by their names.
Himanshu (Sep 01 2022 at 16:32):Daniel Rossberg said:
That's right. The objects are uniquely referenced by their names.
Then I should leave it as it is.
Daniel Rossberg (Sep 01 2022 at 16:34):Or, the check for correct object names needs an additional criterion.
Himanshu (Sep 01 2022 at 16:35):Daniel Rossberg said:
Or, the check for correct object names needs an additional criterion.
Hmm good :idea:.
Himanshu (Sep 01 2022 at 16:36):Check if there exist an object name already then re-prompt to enter a new object name apart from previous one.
Daniel Rossberg (Sep 01 2022 at 16:42):The ConstDatabase::Get() searches for an object with a given name. If it found something, the call-back will be called.

Hmm, the "else if" can be true even if cancel was hitted (!ok). You should test for cancel first (if (!ok) break;) and do the other tests after.

Himanshu (Sep 08 2022 at 17:29):Done :cowboy:
Himanshu (Sep 08 2022 at 17:30):BTW, yesterday I started implementing mouse actions feature.
Himanshu (Sep 08 2022 at 17:31):For now I have came across one derived class DragWindowMouseAction
Himanshu (Sep 08 2022 at 17:32):This class can override the eventFilter() of MouseAction which defines if we drag the menu bar or title bar then the window should move.
Himanshu (Sep 08 2022 at 17:33):First virtual bool QObject::eventFilter(QObject* watched, QEvent* event) = 0; I should make it pure virtual then override in derived class.
Himanshu (Sep 08 2022 at 17:34):If we look into definition of eventFilter()
bool MainWindow::eventFilter(QObject *watched, QEvent *event)
{
static QPoint dragPosition{};
if (watched == menuTitleBar)
{
if (event->type() == QEvent::MouseButtonPress)
{
QMouseEvent* mouse_event = dynamic_cast<QMouseEvent*>(event);
if (mouse_event->button() == Qt::LeftButton)
{
dragPosition = mouse_event->globalPos() - frameGeometry().topLeft();
return false;
}
}
else if (event->type() == QEvent::MouseMove)
{
QMouseEvent* mouse_event = dynamic_cast<QMouseEvent*>(event);
if (mouse_event->buttons() & Qt::LeftButton)
{
if(isMaximized()) return false;//showNormal();
//todo showNormal when dragged
move(mouse_event->globalPos() - dragPosition);
return false;
}
}
}
return false;
}
Here is a variable menuTitleBar which is part of MainWindow.h
Daniel Rossberg (Sep 08 2022 at 17:36):You could make MouseAction::eventFilter() pure virtual, but not QObject::eventFilter(). However, it isn't necessary.
Himanshu (Sep 08 2022 at 17:37):oops
Himanshu (Sep 08 2022 at 17:38):I forgot to add MouseAction::eventFilter()
Daniel Rossberg (Sep 08 2022 at 17:38):At the end, DragWindowMouseAction::eventFilter() should become what MainWindow::eventFilter() is now.
Himanshu (Sep 08 2022 at 17:39):So what we should prefer? MouseAction::eventFilter() or QObject::eventFilter()?
Daniel Rossberg (Sep 08 2022 at 17:42):You should not touch QObject::eventFilter(), but MouseAction is derived from QObject and its eventFilter() method overwrites the one of QObject.
Himanshu (Sep 08 2022 at 17:43):Ahh, I understand now :grinning:
Himanshu (Sep 08 2022 at 17:44):I am on that path. Started implementing the DragWindowMouseAction::eventFilter()
Himanshu (Sep 08 2022 at 17:46):Btw, how DragWindowMouseAction::eventFilter() will access menuTitleBar? Inherit MainWindow?
Daniel Rossberg (Sep 08 2022 at 17:50):If this class needs additional information, you can add them to its constructor.
Himanshu (Sep 08 2022 at 17:56):Ahh, yes, there is a cycle.

Is there a reason why you don't do this on github?
Daniel Rossberg (Sep 15 2022 at 17:04):What's the purpose of MainWindow::DragWindowButtonAction()? See, I proposed a Done() signal for the mouse actions. This allows to switch back to a default action when something was done. E.g., suppose there is an object selection action. When activated, you can click on an object, and the action returns its path - and emits "Done". You can react on this signal by switching back to the default drag mouse action.

Basically it's crashing if I open an existing .g file. This is not on any specific branch, and probably isn't related to anything anyone has done recently. Seems to be OpenGL-related, not the right data it's expecting?

Himanshu (Sep 23 2022 at 09:58):@Sean Mine working fine in windows. Not sure why it is failing in mac. Looks like a segmentation fault issue.

Sean (Sep 23 2022 at 15:35):@Himanshu Sekhar Nayak thanks for checking -- looking at the stack trace, I'd guess it's a piece of invalid data that is being ignored on linux/windows, but mac opengl driver does not like. that 0x0000000580 looks like data. I'm going to try stepping in the debugger to see which param that is.
Sean (Sep 23 2022 at 17:07):I think there's some initialization order issue. If I comment out the DisplayManager() constructor's two lines that make gl calls, it works. So presumably opengl is not yet initialized at the time of construction.

This is probably caused by the Qt::FramelessWindowHint flag. For the sake of a modern look, the system menu was eliminated and, at least with Windows and KDE, replaced by the main window's menu bar. On these systems, the minimize/maximize/exit icons are however still there.

It does it with all .g's, so it's not specific to the geometry. something is probably getting calculated differently (obviously half of what it should be in both dimensions).

I do have a retina display and high dpi scaling was turned on, but I get the same result even if I turn scaling off.
Sean (Sep 26 2022 at 03:42):but you're definitely on to something there. if I multiple h and w by 2 in Display::resizeGL() it displays perfectly: Screen-Shot-2022-09-25-at-11.40.52-PM.png

For frameGeometry().topLeft(), isMaximized(), move() to work they need an object from MainWindow, so I have done something like that.
Himanshu (Sep 27 2022 at 14:14):If I am right, here parent should be MainWindow for MouseAction ?
Himanshu (Sep 27 2022 at 16:08):Here is a patch but I can't figure out how to make frameGeometry().topLeft(), isMaximized(), move() work. Changes-On-6f942d.patch
Daniel Rossberg (Sep 27 2022 at 17:13):You are asking the right question :grinning: We didn't talked about this yet. But, while looking at this, I realized, that your current code aim at the wrong widget. Moving the main window is not what we are looking for. Instead, Display is the widget we want different mouse actions for. I.e., MouseAction(QObject* parent, Display* watched);.

So menuTitleBar shouldn't be the target widget?
Himanshu (Sep 28 2022 at 14:25):So the goal is to move these mouse functions to their respective classes which are in Display.h?
void mouseMoveEvent(QMouseEvent *event) override;
void mousePressEvent(QMouseEvent *event) override;
void mouseReleaseEvent(QMouseEvent *event) override;
void wheelEvent(QWheelEvent *event) override;
void keyPressEvent(QKeyEvent *k) override ;
The mouse behavior on the menuTitleBar is a bit boring. No need to create a class hierarchy for this. The mouse actions in the Display widget are much more exciting. Here we need a frame work to create easily new kinds of interactions.
And yes, the has to be done in the eventFilter() method.

So I guess we have to shift the MouseAction object to Display.h instead of keeping it inside MainWindow?
Himanshu (Sep 29 2022 at 15:03):Just want to clear this so that I can start again :sweat_smile:
Himanshu (Sep 29 2022 at 15:03):I will restore the DragWindowMouseAction to its original place e.g removing that class.
Himanshu (Sep 29 2022 at 15:04):Then I will implement them in separate classes for all the override that are in Display.h
Daniel Rossberg (Sep 29 2022 at 17:19):You should save (rescue) the MouseAction and DragWindowMouseAction classes and reset the source tree, e.g. by deleting the branch and creating a new one. Then, move the MouseAction class there and make the constructor look like MouseAction(QObject* parent, Display* observed). The design of DragWindowMouseAction wasn't bad. It can be used as a template for the new mouse rotation action class on Display. This way, you have hopefully an easier start.

So all the functions e.g DragWindowButtonAction() will be placed inside Display.h and so on
Daniel Rossberg (Sep 29 2022 at 17:45):No. First, this task is about defining functionality outside from the Display class, i.e., moving stuff out. In addition, Display has no use for a drag window action. But, it would be good if you had this code to hand and look up there to speed up development.
Himanshu (Sep 29 2022 at 17:48):Alright :+1:🏻. I will start tomorrow then. Late night here. I will create a new branch and will send a PR.
Himanshu (Oct 05 2022 at 19:14):@Daniel Rossberg Should I go with friend for all those derived class of MouseAction so that they can access those private variables of Display class?
Himanshu (Oct 05 2022 at 19:14):or add some getters inside Display class?
Himanshu (Oct 05 2022 at 20:04):Btw if (watched == m_watched) Will it even be true? Since both are different classes or I am missing somethin here?
Daniel Rossberg (Oct 06 2022 at 07:04):You should write interfaces for the functionality you need in the mouse action. E.g., don't hand over the camera object but write Display::MoveCamera(), Display::RotateCamera(), etc. functions.

m_watched should be of Display type, which is, after some levels of inheritance, a QObject, the type of watched.
Sean (Oct 07 2022 at 05:16):Just FYI, we have a team of capstone students using arbalest GUI as the base for creating a new geometry V&V tool.

Your code is a bit unexpected, and (without having tested it) I doubt that it works. For example, only the wheel action should be active: The last mouse action you create the MainWindows constructor is the wheel action.
Daniel Rossberg (Oct 09 2022 at 16:09):You seem to doing hard in understanding what kind of objects are needed. This is about the generalization of the mouse interactions. At the moment, there is only one mouse interaction implemented: The movement of the camera. This shall be the start point.
Object oriented means, that there shall be objects which take the responsibility for the different behavior modes. However, at the moment there is only one behavior, the default one, the camera movement.
Daniel Rossberg (Oct 09 2022 at 16:13):All behavior specific code has to be part of this class.
In your case you need two new classes:
Daniel Rossberg (Oct 09 2022 at 16:16):The current mouse behavior is implemented like
void Display::mouseMoveEvent(QMouseEvent *event) {
const int x = event->x();
const int y = event->y();
int globalX = event->globalX();
int globalY = event->globalY();
bool resetX = false, resetY = false;
if(prevMouseX != -1 && prevMouseY != -1 && (event->buttons() & (rotateCameraMouseButton|moveCameraMouseButton))) {
if (skipNextMouseMoveEvent) {
skipNextMouseMoveEvent = false;
return;
}
if(event->buttons() & (rotateCameraMouseButton)) {
const bool rotateThirdAxis = QApplication::keyboardModifiers().testFlag(rotateAroundThirdAxisModifier);
camera->processRotateRequest(x- prevMouseX, y - prevMouseY,rotateThirdAxis);
}
if(event->buttons() & (moveCameraMouseButton)){
camera->processMoveRequest(x- prevMouseX, y - prevMouseY);
}
forceRerenderFrame();
const QPoint topLeft = mapToGlobal(QPoint(0,0));
const QPoint bottomRight = mapToGlobal(QPoint(size().width(),size().height()));
int newX = -1;
int newY = -1;
if (globalX <= topLeft.x()) {
newX = bottomRight.x()-1;
resetX = true;
}
if (globalX >= bottomRight.x()) {
newX = topLeft.x()+1;
resetX = true;
}
if (globalY <= topLeft.y()) {
newY = bottomRight.y()-1;
resetY = true;
}
if (globalY >= bottomRight.y()) {
newY = topLeft.y()+1;
resetY = true;
}
if (resetX || resetY) {
prevMouseX = resetX ? mapFromGlobal(QPoint(newX,newY)).x() : x;
prevMouseY = resetY ? mapFromGlobal(QPoint(newX,newY)).y() : y;
QCursor::setPos(resetX ? newX : globalX, resetY ? newY : globalY);
skipNextMouseMoveEvent = true;
}
}
if(!resetX && !resetY) {
prevMouseX = x;
prevMouseY = y;
}
}
void Display::mousePressEvent(QMouseEvent *event) {
document->getDisplayGrid()->setActiveDisplay(this);
prevMouseX = event->x();
prevMouseY = event->y();
}
void Display::mouseReleaseEvent(QMouseEvent *event) {
prevMouseX = -1;
prevMouseY = -1;
}
void Display::wheelEvent(QWheelEvent *event) {
if (event->phase() == Qt::NoScrollPhase || event->phase() == Qt::ScrollUpdate || event->phase() == Qt::ScrollMomentum) {
camera->processZoomRequest(event->angleDelta().y() / 8);
forceRerenderFrame();
}
}
This should be implemented as something like this
bool MoveCameraMouseAction::eventFilter(QObject* watched, QEvent* event) {
if (watched == m_watched) {
if (event->type() == QEvent::MouseMove) {
// put the code of Display::mouseMoveEvent() here
}
else if (event->type() == QEvent::MouseButtonPress) {
// put the code of Display::mousePressEvent() here
}
else if (event->type() == QEvent::MouseButtonRelease) {
// put the code of Display::mousePressEvent() here
}
else if (event->type() == QEvent::Wheel) {
// put the code of Display::mousePressEvent() here
}
}
return ?
}
Variables like prevMouseX and prevMouseY should become member of MoveCameraMouseAction.
Himanshu (Oct 10 2022 at 11:03):Ahh my bad. I though for every different mouse event I have to create separate class. I will solve it by today.
Himanshu (Oct 10 2022 at 20:43):@Daniel Rossberg Should we also shift bool bool skipNextMouseMoveEvent = false; inside MoveCameraMouseAction class ?

Himanshu (Oct 11 2022 at 12:46):While navigating through MainWindindow src file, I saw QMouseEvent* mouse_event = dynamic_cast<QMouseEvent*>(event); where dynamic_cast is used and I added static_cast inside respective event->type(). So which will be right?
Himanshu (Oct 11 2022 at 12:47):As far I know If there is a surety we will never cast to wrong object then we can avoid dynamic_cast and use static_cast but I don't know which will be best fit for these since dynamic_cast has runtime overhead.

Using static_cast is okay. dynamic_cast is rather a test, if the variable has the desired type. The result of a dynamic_cast should be tested for nullptr too. BTW, it wasn't the MainWindow with these mouse event casts ;)

Hmm understood. One return false; since all other events are ignored, and the filter returns false to allow them to be sent on to the target widget.
Himanshu (Oct 13 2022 at 14:13):@Daniel Rossberg We need a Display object that need to be passed MoveCameraMouseAction(QObject* parent, Display* watched) and here the parent will be a object of MainWindow?
Himanshu (Oct 13 2022 at 15:50):So now we have to do something like this. Create another class where it can select the object and highlight it. But before that if we select a sub-object inside object dock then it should also highlight too.

Daniel Rossberg We need a
Displayobject that need to be passedMoveCameraMouseAction(QObject* parent, Display* watched)and here the parent will be a object ofMainWindow?
Good question. The watched parameter is a Display instance, but who manages these instances? I don't think it's MainWindow.
Daniel Rossberg (Oct 13 2022 at 16:02):The MainWindow has a member documentArea which contains the tab widgets. documentArea->widget(index) is of type DisplayGrid (if it isn't the help page), which contains an array of displays.
Daniel Rossberg (Oct 13 2022 at 16:04):Maybe, the mouse action objects should be managed by DisplayGrid too? It would need a MouseAction instance for each Display instance.
Daniel Rossberg (Oct 13 2022 at 16:08):DisplayGrid could have a setMoveCameraMouseAction() method, which allows to set the required action in the MainWindow class.
Himanshu (Oct 15 2022 at 11:51):Daniel Rossberg said:

documentArea->widget(index)is of type DisplayGrid (if it isn't the help page), which contains an array of displays.
Okay, I see that it is dynamically casted to DisplayGrid in MainWindow. Also I saw this, documentArea->addTab(new HelpWidget(), "Quick Start"); that you talked about Help page.
Himanshu (Oct 15 2022 at 13:48):So every time there is a new tab, then there should be always new mouse actions for each tab.
Himanshu (Oct 16 2022 at 06:33):So there are 4 displays right?
Daniel Rossberg (Oct 16 2022 at 14:50):I don't know if their number is limited :thinking:

Himanshu (Oct 16 2022 at 14:51):inside DisplayGrid class ^^

Himanshu (Oct 16 2022 at 14:52):So I thought are they referring to viewport?
Himanshu (Oct 16 2022 at 14:53):Then I saw this activeDisplay = displays[3]; and thought this should be the viewport. Right?
Daniel Rossberg (Oct 16 2022 at 15:37):Himanshu Sekhar Nayak said:

Himanshu (Oct 27 2022 at 17:23):@Daniel Rossberg Currently I am thinking to do like this for select function.
QString SelectMouseAction::getSelectedRegionPath() const {
BRLCAD::ConstDatabase::Hit *obj = dynamic_cast<BRLCAD::ConstDatabase::Hit *>(m_watched->getDocument()->getDatabase());
if (obj != nullptr) {
return obj->Name();
}
return nullptr;
}
I'm afraid, this won't work.
Better: In eventFilter() on if (event->type() == QEvent::MouseButtonPress) shoot a ray where the click was. If something was hit, memorize obj->Name() on a member variable m_selected and emit Done(this). Then
QString SelectMouseAction::getSelected() const {
return m_selected;
}
BTW, if there is a region, m_selected contains a region's path, but if there are no regions at all (for example), it can contain a solid's name too.
Himanshu (Oct 28 2022 at 15:12):@Daniel Rossberg In order to shoot a ray which is new to me so first I have to fetch the my mouse x and y co-ordinates.
Himanshu (Oct 28 2022 at 15:17):and also get the direction. And then initialize ray origin and direction coordinates and shoot that ray using this one m_database.ShootRay(ray, callback, BRLCAD::ConstDatabase::StopAfterFirstHit);
Daniel Rossberg (Oct 28 2022 at 16:06):Maybe, RaytraceView can give you a hint on how this can be done. In RaytraceView a ray for every pixel will be shot. You need only one pixel.
Himanshu (Oct 29 2022 at 16:40):@Daniel Rossberg Is this one virtual bool operator()(const BRLCAD::ConstDatabase::Hit& hit) throw(){} actually checks if a ray is hit or not? If yes then why it always return false.
Himanshu (Oct 29 2022 at 16:42):That function operator overloading function is inside class RayTraceCallback : public BRLCAD::ConstDatabase::HitCallback but it is in RaytraceView.cpp file.

The return value isn't meant for you directly, but for the algorithm behind BRLCAD::Database::ShootRay(). It's explained in the ConstDatabase.h file, line 184 ff.:
/** return true: go on; false: stop
The return value gives the calling function the possibility to optimize.
However be aware the return value may be ignored. */
I.e., always returning false means: Stop after the first hit.
Himanshu (Oct 30 2022 at 15:51):@Daniel Rossberg What does this image point and model point means?
QVector3D imagePoint(column, h - row - 1., 0.);
QVector3D modelPoint = m_transformation.map(imagePoint);
The image coordinates should be more-or-less screen coordinates (y-coordinate reversed?) The transformation maps them to model coordinates (where the BRL-CAD geometry lives). Because the screen is 2D, but the model is 3D, the z-coordinate of the screen is set to 0. In fact, the image of a point on the screen in model space is not a point but a line.
Himanshu (Oct 31 2022 at 16:30):@Daniel Rossberg Here is what I have done so far....
bool SelectMouseAction::eventFilter(QObject* watched, QEvent* event) {
bool ret = false;
if (watched == m_watched) {
if (event->type() == QEvent::MouseButtonPress) {
QMouseEvent* mouseEvent = static_cast<QMouseEvent*>(event);
if (mouseEvent->button() == Qt::LeftButton) {
const int x = mouseEvent->x();
const int y = mouseEvent->y();
int w = m_watched->getDocument()->getRaytraceWidget()->width();
int h = m_watched->getDocument()->getRaytraceWidget()->height();
QVector3D &eyePosition = m_watched->getCamera()->getEyePosition();
QMatrix4x4 m_transformation;
QVector3D directionStart = m_transformation.map(eyePosition);
QVector3D directionEnd = m_transformation.map(QVector3D(0., 0., 0.));
QVector3D direction = directionEnd - directionStart;
direction.normalize();
QVector3D imagePoint(x, h - y - 1., 0.);
QVector3D modelPoint = m_transformation.map(imagePoint);
RayTraceCallback callback(direction, m_watched->getDocument()->getRaytraceWidget()->getColor());
BRLCAD::Ray3D ray;
ray.origin.coordinates[0] = modelPoint.x();
ray.origin.coordinates[1] = modelPoint.y();
ray.origin.coordinates[2] = modelPoint.z();
ray.direction.coordinates[0] = direction.x();
ray.direction.coordinates[1] = direction.y();
ray.direction.coordinates[2] = direction.z();
// Shoot a ray
m_watched->getDocument()->getDatabase()->ShootRay(ray, callback, BRLCAD::ConstDatabase::StopAfterFirstHit);
// Check if a ray intersects or hit
// Dynamically cast BRLCAD::ConstDatabase to BRLCAD::ConstDatabase::Hit and return region Name
emit Done(this);
ret = true;
}
else {
ret = false;
}
}
}
return ret;
}
You need to write your own call-back class.
Himanshu (Nov 01 2022 at 16:47):@Daniel Rossberg What is the purpose of QColor m_color; in RayTracecallback class? Do you need that?
Daniel Rossberg (Nov 01 2022 at 17:15):RaytraceView generates a ray-trace image: For every pixel of the screen/image a ray will be shot and the corresponding colour will be determined. This colour is based on the colour of the object hit and the hitting angle. The variable m_colorholds this colour.
Daniel Rossberg (Nov 01 2022 at 17:16):Of course, you don't need this for your selection call-back.
Himanshu (Nov 05 2022 at 07:06):@Daniel Rossberg Should we make the select mouse action as a toggle action? So after select operation is finished, it can switch back to move mouse action.
Daniel Rossberg (Nov 05 2022 at 16:00):I wouldn't call it "toggle action" (I've different associations with this name), but yes: Switch back to the mouse move action after the selection has finished.
Himanshu (Nov 07 2022 at 21:41):@Daniel Rossberg okay, I am created a slot that will show the region name in the object docks. But looks like my ray is not shooting the region since I am getting empty in m_selected.
Daniel Rossberg (Nov 08 2022 at 18:10):Good that you implemented the slot. The issues aren't surprising. Now, you should debug your code: Add a break point at the beginning of SelectMouseAction::eventFilter().
x and y (the coordinates of the mouse click) reasonable/as expected? You may need more than one click to check this.modelPoint reasonable/as expected? Check your example geometry (e.g. m35.g) with another program (e.g. mged) to see at which coordinate you actual clicked. Himanshu (Nov 09 2022 at 06:09):@Daniel Rossberg Meanwhile here is the slot that I had done. You can have a look. I have not tested it yet but looks good. Any suggestion like the name of the function or something?
bool ObjectTreeWidget::build(QString& selected, int objectId) {
if (objectId != 0) {
ObjectTree::VisibilityState visibilityState = document->getObjectTree()->getObjectVisibility()[objectId];
if (visibilityState == ObjectTree::FullyVisible || visibilityState == ObjectTree::SomeChildrenVisible) {
if (document->getObjectTree()->getNameMap()[objectId] == selected) {
objectIdTreeWidgetItemMap[objectId]->setSelected(true);
document->getProperties()->bindObject(objectId);
return true;
}
}
else {
return false;
}
}
for (int childObjectId : document->getObjectTree()->getChildren()[objectId])
{
bool isSelected = build(selected, childObjectId);
if (isSelected == false) {
continue;
}
if (objectId != 0) {
objectIdTreeWidgetItemMap[objectId]->setExpanded(true);
}
return true;
}
return false;
}

modelPoint is not working because sometimes there is a region name for a click and sometimes even if I click on a object, m_selected shows empty. Daniel Rossberg (Nov 10 2022 at 16:49):Are this the coordinates you expected?
I'm afraid, you have to set a break point there and debug it yourself. Something must be wrong there.

Why don't you iterate over fullPathMap?
Himanshu (Nov 11 2022 at 06:28):Oops I forgot that m_selected stores full path of the region name. Unless I should make it like document->getObjectTree()->getFullPathMap()[objectId] == selected ?
Daniel Rossberg (Nov 11 2022 at 17:20):Yes, you should look for the selected path in this map.
Himanshu (Nov 12 2022 at 17:01):So here it is --->
void ObjectTreeWidget::build(QString selected) {
int size = document->getObjectTree()->getFullPathMap().size();
for (int objectId = 1; objectId < size; ++objectId) {
ObjectTree::VisibilityState visibilityState = document->getObjectTree()->getObjectVisibility()[objectId];
if (visibilityState == ObjectTree::FullyVisible || visibilityState == ObjectTree::SomeChildrenVisible) {
if (document->getObjectTree()->getFullPathMap()[objectId] == selected) {
objectIdTreeWidgetItemMap[objectId]->setSelected(true);
document->getProperties()->bindObject(objectId);
}
}
}
}
I have tested it out and looks like when we click on multiple object, the previous selected ones stays setSelected() to true.
Himanshu (Nov 14 2022 at 15:03):@Daniel Rossberg My pr is ready and I have some additional design touches that I wanted to ask if it suits you.
selected path then the object dock should be expanded till it's last / and show selected there. Or we should it only make the selected to setSelected(true) and no need of setExpanded()? Himanshu (Nov 14 2022 at 15:04):For now the pr is ready and ready to test for select action. Let me know if there is anything needs to do.
Daniel Rossberg (Nov 14 2022 at 18:09):Himanshu Sekhar Nayak said:
Daniel Rossberg My pr is ready and I have some additional design touches that I wanted to ask if it suits you.
- When we click on an empty area which is not an object, so we should not be getting any region names. So at that moment should I clear the properties dock whenever it gets empty region name or make it stay there? Another example like the properties dock already shows the details of a selected object and now I click on empty area and the properties dock is still same and not updates. So should I make it clear?
Let the properties dock unchanged. Clicking in an empty area is the same as canceling the selection procedure.
- I have a thought like when we get a
selectedpath then the object dock should be expanded till it's last/and show selected there. Or we should it only make the selected tosetSelected(true)and no need ofsetExpanded()?
Do not setExpanded(). Show the selected object together with its siblings.
- When we click on select button icon then the background should be change to show that the button is active or selected instead of just a button which acts like other buttons like new, save, open...... . So should I change the background once it is selected?
Doesn't do setCheckable(true) the job? Why does it work for toggleGridAct/toggleGrid?
Daniel Rossberg (Nov 14 2022 at 18:14):Himanshu Sekhar Nayak said:

This will need some time. However, here is my first one: ObjectTreeWidget::build() is a bad name. You don't build something. Instead, look at line 110: You select something. Therefore, ObjectTreeWidget::select() would be a better name.
Himanshu (Nov 15 2022 at 08:02):Ahh I forgot that there is one thing to add so that background will be changed once it is checked.
#toolbarButton:checked { background-color:"$Color-ButtonCheckedMask"; }
Himanshu (Nov 15 2022 at 08:04):But the problem is background color is not able to find that macro $Color-ButtonCheckedMask. I have tried to clean the solution and rebuild it but no luck but once I set it to like this #toolbarButton:checked { background-color:"$Color-ButtonHoverMask"; } or set the background color to yellow without any macro, it works. I made sure that the macro is present in both light and dark theme but looks like didn't work.
Himanshu (Nov 15 2022 at 15:30):I found a bug. If the grid button or select object button is enabled for one document then once we create a another new document, the buttons remains active. These buttons should act according to the document right? @Daniel Rossberg
Himanshu (Nov 15 2022 at 15:33):One thing we can do like to check for every document for grid and select act and setChecked() accordingly. We can do it here MainWindow::onActiveDocumentChanged() but problem is that we can't access those variables which are inside MainWindow::prepareUi().
Himanshu (Nov 15 2022 at 15:43):Or we can do a signal slot connection to solve this issue?

Not necessarily. I personally would consider it rather confusing if the grid would be a property of the document.

Not necessarily. I personally would consider it rather confusing if the grid would be a property of the document.
So once grid and select is active then it should remain active for all documents right? Because here you can see documents[activeDocumentId]->getDisplayGrid()->getActiveDisplay()->selectObjectEnabled == false. This only works when the button is clicked but not on active document change.
Daniel Rossberg (Nov 16 2022 at 20:39):I expected that you bring up this point :)
What's important is that the behavior is all-in-all consistent. That the behavior of the grid (display property) and select (mouse behavior) button are different, would be reasonable. You can however define how you think the behavior should be and implement it that way.
Sean (Nov 16 2022 at 23:14):Is there any key binding or way to drop arbalest out of full-screen mode? On Mac, there's no maximize/minimize buttons when it's full screen -- Only the menu bar. Typically Mac apps have an "Exit Fullscreen" menu option under View, or the window fills the whole desktop without going fullscreen so buttons remain accessible.

Ahh I see, there is no such minimize, maximize and close buttons.
Sean (Nov 17 2022 at 13:20):Yeah it’s not truly going full screen on Windows so it still has the buttons there
Sean (Nov 17 2022 at 13:22):I think I recall there being some Qt hint/preference/call that tells it to keep the Window but not sure..
Himanshu (Nov 17 2022 at 13:22):Sean said:

Yep, during launch it goes full screen and I can see the buttons in windows. Are we also expecting those buttons on Mac too, right?
Himanshu (Nov 17 2022 at 13:23):I will look into this, why those buttons are not visible in Mac.
Sean (Nov 17 2022 at 13:23):We’ll without them, it’s impossible to minimize or resize.. :)
Sean (Nov 17 2022 at 13:23):Maybe Qt::WindowFullscreenButtonHint
Himanshu (Nov 17 2022 at 13:24):Ok, I am on it.
Sean (Nov 17 2022 at 13:25):It’s actually nice/fine that there’s not buttons displayed, but then there needs to be some menu option to get out of full screen if it stays buttonless
Sean (Nov 17 2022 at 13:26):The Mac application menu is at the top but it’s a permanent fixture on Mac
Daniel Rossberg (Nov 17 2022 at 19:14):My guess from September 25:
Sean said:
Is there a keybinding to get it out of the default fullscreen or resize the window? On mac, I can't seem to minimize it which makes it impossible to get to the Desktop while the app is running.
This is probably caused by the Qt::FramelessWindowHint flag. For the sake of a modern look, the system menu was eliminated and, at least with Windows and KDE, replaced by the main window's menu bar. On these systems, the minimize/maximize/exit icons are however still there.

Sean (Dec 02 2022 at 05:05):@Himanshu Sekhar Nayak Thank you for all your hard work. I was very much impressed by both the magnitude and quality of effort you put into the GUI work. Your accomplishments have been outstanding.
Sean (Dec 02 2022 at 05:21):The improvements you made to arbalest's usability made it possible for another team of students to use the GUI as a base for developing an entirely new geometry V&V application. It also will hopefully get us one step closer to that overarching goal of a new modern CAD GUI.
Sean (Dec 02 2022 at 05:23):I like your write-up and noticed your points about GED and MOOSE. If we can figure out how to combine the two, we'll gain the full expressiveness of mged/archer with a vastly more elegant front-end design.

Daniel Rossberg (Dec 17 2022 at 17:54):@Himanshu Sekhar Nayak, I accepted your PR. It isn't perfect yet, but the form was good, such that nothing was preventing it from being accepted. The remaining work in fine tuning and tweaking.
Daniel Rossberg (Dec 17 2022 at 18:48):I applied Sean's PR which fixes the OpenGL issues on Mac. Maybe, you can test it on Windows.

Hmm, copied the DLL and now arbalest works. Nice.
Himanshu (Apr 22 2023 at 21:55):Tried removing the install/moose/ and done a fresh start but still not able to find DLL file. But anyway now it works after copying it.
Himanshu (Apr 25 2023 at 09:17):Now arbalest is able to run through MOOSE. What's next?
Himanshu (Apr 25 2023 at 09:18):Tested out selection, raytrace and other things on arbalest. It works too.
Sean (Apr 26 2023 at 06:50):Screenshot would be great to see! :)
Sean (Apr 26 2023 at 07:00):Would be great to figure out a proper way to run libged commands via MOOSE. It's not the same architecture as it's a string-based procedural interface and MOOSE is a more proper OO API, but having some sort of executor interface in the API would go a long way towards bridging a massive swath of capability (e.g., so you could run commands in arbalest and have it reflected automatically) ... if it can be done in a way that keeps the OO model in sync. So if you have a comb and a sph, and then you ran "mvall sph sph.new" via moose, that its representation of the comb would correctly reflect a reference to sph.new instead of the sph it originally read from disk.

MOOSE has a CommandString module (experimental), which serves as interface to libged. Set MODULE_COMMANDSTRING in MOOSE's CMake to on, to activate it.
In Examples/CommandString/PrintTitle.cpp you can find an example, where a database is opened with C++ API and the title is retrieved by sending title to libged.

Oh, that's exciting to hear! I missed seeing that addition. Will definitely check that out..
Sean (Apr 26 2023 at 16:13):We've been having internal code reviews on the qged code, so I'm still looking at ways to merge the efforts if we can maintain the clean coding you have in arbalest's design. Maybe leverage the key pieces in qged like the command window widget (which might be super trivial now with a way to call commands), and the quad view (a lot of work went into making it highly performant, so that one might be tricky). Still learning about the two hierarchy views.

Hello Sir, my name is Vidit Jain and I am a second year undergrad at BITS Pilani Goa campus. I am exploring open source and open to learn new technologies. Would love some insights on how should I start contributing to BRL-CAD. I was going through GSOC 2024 projects and I am genuinly interested in working on project "New BRL-CAD GUI #27". Looking forward to hear from you. Thank you
Hi @Vidit Jain, welcome at BRL-CAD. Lets do our conversion here, where other mentors can jump in. E.g., @Himanshu Sekhar Nayak did a lot of the GUI development, and he wants to be a mentor this year, if BR_CAD will be accepted for GSoC :wink:
First, you should learn about BRL-CAD, what it is and how it works:
Vidit Jain (Feb 09 2024 at 10:18):@Daniel Rossberg

Hi Vidit, you can go through my progress and where I left it here https://brlcad.org/wiki/User:H1manshu/GSoC2022/Project_Report. But before that make yourself familiar to MGED and Arbalest. Then see if you want to come up with new ideas or find that thing which is missing in Arbalest but is present in MGED.
Vidit Jain (Feb 09 2024 at 19:48):Thank you, sure, I will start reading from tomorrow :blush:
Daniel Rossberg (Feb 13 2024 at 08:55):@Vidit Jain, there is no installation file for Arbalest yet. You have to build it by yourself. On top of that, the build is currently broken. However, you can start setting up your development environment, and maybe, we can fix the build meanwhile.
Daniel Rossberg (Feb 13 2024 at 09:07):As the first step for building Arbalest, you have to build and Install BRL-CAD:
Some additional tips:
Vidit Jain (Feb 13 2024 at 09:10):Thanks a lot for the guidance! Will do all of this as soon as possible.

Daniel Rossberg (Feb 15 2024 at 10:50):Building arbalest should be possible again. I could do it with Debian bookworm, at least.
Daniel Rossberg (Feb 21 2024 at 08:26):Vidit Jain said:
What should I do next? Should I try installing Arbalest?
There is an issue with building the MOOSE library with Visual Studio, but you can start setting it up nevertheless.

That is a bug and initialization/driver related, but see if it still flickers after you open a geometry database. There are a bunch of sample models in the share/db folder. Opening any of them should initialize the window to a dark blue or black background. Then you can see if geometry displays. If it does, then that will confirm it's a startup issue. If nothing displays, then there's a deeper issue with the display manager context on your environment to investigate.

Looks like you have to specify the brlcad version too.

After building moose, install it too by make install
Daniel Rossberg (Mar 08 2024 at 17:50):@Vidit Jain, you have to install brlcad too: make install
Install it to a directory, where you have write rights, e.g. /home/vidit/bin/brlcad. The CMake brlcad detection script expects the directory structure from an installation.
In addition, you should include the brlcad bin directory (/home/vidit/bin/brlcad/bin?) in your PATH shell environment variable. This way, it's easier to work with the many BRL-CAD programs ... and you don't need to set anything in CMake, because the brlcad-config script will automatically detected and all necessary information retrieved from it.
Unfortunately, there is no brlcad-config for Windows.
Himanshu (Mar 08 2024 at 17:52):No brlcad-config for windows due to which I have to specify version :sweat_smile:

Hmm, strange. You are on Linux? Where is your installation directory? How did you set it?
Yes I am on linux. My vase directory is desktop/brlcad . I firstly followed the compiling guidelines to compile brlcad. I than compiled it successfully. Than I installed it using sudo make install. But no bin folder is formed
Daniel Rossberg (Mar 10 2024 at 12:35):In this case, you installed brlcad into a different directory. In fact a directory, where you need install privileges.
The install directory is set in CMake via the CMAKE_INSTALL_PREFIX (I think) variable. What is its value? You can keep it or change it to a folder where you don't need root privileges.
BTW, when running make install, its output tells you where it copies the files.
Vidit Jain (Mar 12 2024 at 15:51):@Himanshu Sekhar Nayak @Daniel Rossberg
after running make installed, it got installed a directory /usr/brlcad/rel-7.38.1/bin and a bin folder was also there.. is this the currect bin?
Vidit Jain (Mar 12 2024 at 16:02):Even after adding it to the path its giving the same error

Sean (Mar 12 2024 at 16:46):You didn’t open a new terminal..
Daniel Rossberg (Mar 12 2024 at 16:46):The script is run only once when the shell opens.

Vidit Jain (Mar 12 2024 at 16:56):Also while building should I specify brlcad vcersion?

Vidit Jain said:
Also while building should I specify brlcad vcersion?
Daniel Rossberg (Mar 12 2024 at 16:57):There should be no need to specify anything, because brlcad-config should be found.

Still the same error while building moose :sob:
Daniel Rossberg (Mar 12 2024 at 17:10):You didn't started from scratch. It refers to the header files in your build directory. Instead, it should refer to /usr/brlcad/rel-7.38.1 now.
Vidit Jain (Mar 12 2024 at 17:12):I started from scratch only.. I cloned it in the brlcad folder on my desktop. Should I try it in other location?
Daniel Rossberg (Mar 12 2024 at 17:17):In your screenshot, I see references to /home/vidit/Desktop/brlcad/include/bu/bitv.h. But, your MOOSE build should not know about /home/vidit/Desktop/brlcad. Instead, it should know /usr/brlcad/rel-7.38.1.
Therefore, clean up your MOOSE build directory before running CMake again.
Vidit Jain (Mar 12 2024 at 17:21):I cloned the moose again, but still its refering to that only.. may be its because of the wrong PATHs that I setup earlier?
Vidit Jain (Mar 12 2024 at 17:25):But when I am checking .bashrc, there are no other variables
Daniel Rossberg (Mar 12 2024 at 17:25):What do you mean by "clone again"? git clone? That's not necessary, because you didn't change anything. Just remove everything what's not in the repository.
Daniel Rossberg (Mar 12 2024 at 17:26):Where is your MOOSE source directory? Where is your MOOSE build directory?

Yaa I did git clone.
Vidit Jain (Mar 12 2024 at 17:28):Daniel Rossberg said:
Where is your MOOSE source directory? Where is your MOOSE build directory?
Base is on my desktop, and build is inside base
Daniel Rossberg (Mar 12 2024 at 17:29):Then, remove the build.
Vidit Jain (Mar 12 2024 at 17:30):So I should build and install in base directory itself?
Daniel Rossberg (Mar 12 2024 at 17:31):No. Remove the build directory and recreate it with CMake.
Vidit Jain (Mar 12 2024 at 17:37):Daniel Rossberg said:
No. Remove the build directory and recreate it with CMake.
By "create with CMake" what do you exactly mean? should I make it using mkdir or is there a way by which I can make it directly through CMake
Daniel Rossberg (Mar 12 2024 at 17:38):How did you your first run of CMake on MOOSE?
Vidit Jain (Mar 12 2024 at 17:38):i made a build folder first
Vidit Jain (Mar 12 2024 at 17:39):than I run "cmake .."
Daniel Rossberg (Mar 12 2024 at 17:40):Okay, then mkdir build, cd build, and cmake ...
Vidit Jain (Mar 12 2024 at 17:40):yes
Vidit Jain (Mar 12 2024 at 17:44):Still while running make install, refering to desktop one only
Daniel Rossberg (Mar 12 2024 at 17:46):Did you removed the old build directory first, before recreating it? Are you doing this in a new shell?
Vidit Jain (Mar 12 2024 at 17:46):Daniel Rossberg said:

Sean (Mar 12 2024 at 20:17):When in doubt, delete the build directory and rerun cmake. I think there are some situations where existing files affect subsequent cmake behavior.

Daniel Rossberg (Mar 15 2024 at 07:58):You can find the brlcad.dll in your MOOSE installation directory (lib subdirectory). Copy this DLL to where your arbalest.exe is, or include your ~/MOOSE/lib directory in your path environment variable.
Vidit Jain (Mar 15 2024 at 08:33):Ya its working now.. thanks a lot
Vidit Jain (Mar 15 2024 at 08:35):Do we have some sample databses which I can test on arbalest?

It depends on the complexity of the feature that you propose. If we feel that you can implement a feature which is complex and going to take more time. Then length of the project can be changed.

You don't need to open the project in Qt. You can open in visual studio 2022 itself.
Himanshu (Mar 15 2024 at 15:49):Open arbalest solution in visual studio then in your right side you can expand arbalest section to see source files.

Through dragging mouse left click, you can change too.

Himanshu (Mar 15 2024 at 19:23):

Ig it is intended to function like this only. @Sean @Daniel Rossberg if you can tell
Daniel Rossberg (Mar 17 2024 at 11:47):I don't know if this is related, but there was a problem with the start plane of the ray-trace. It can be inside or behind the geometry.
Sean (Mar 23 2024 at 21:28):@Vidit Jain the raytrace viewport should match what's displayed in the wireframe, at least that would be my expectation. As daniel implied, it might simply be an issue of needing to move the camera backwards, outside of the model. That should be a pretty simple change if it's not doing that already.
Daniel Rossberg (Mar 24 2024 at 16:30):@Vidit Jain, before implementing higher features, you should think about fixing and completing the basic ones. Some keywords:

Vidit Jain, before implementing higher features, you should think about fixing and completing the basic ones. Some keywords:
- Mouse interactions, e.g. selection of regions and primitives
- Navigation in the geometry, e.g. highlighting the selected object
- Think about Geometry Verification and Validation GUI in Qt (AI Project) as well. I would like to use Archer to explore geometries, find regions there, see what is around them, find overlaps, compute volumes, ...
- I find the current GUI a bit hard to maintain, because it uses special solutions for its GUI elements and has a complicated coloration. This gives it a fancy look, but makes it harder to port between operating systems. Any suggestions? Do you have access to a macOS computer?
I am updating my proposal, I will send it once I will edit it after adding all these things

When I am opening those files in visual studio, a blanck screen is coming, with no code

Daniel Rossberg (Apr 04 2024 at 14:12):Hi @Vidit Jain, to complete your application, you should provide a patch. Sean came up with some ideas regarding such patches. However, because you want to work on the GUI, I would like to see a patch for arbalest, which shows that you are able to work on it. Is there something, which can easily improved?

One thing you can submit either:
- Check why mouse selection is not working in windows. You can debug and see.
- Once a new tab is created, you can activate mouse selection button and it stays active even if you close it. Same applies if you open a .obj file and activate the mouse selection and close the tab, the mouse selection stays active. Find a way to disable it.
I have started working on first one
Sean (Apr 08 2024 at 14:16):Remember what I put in my earlier post also -- some code submission is vastly more important than no code submission. If you can't figure it out, work on something even simpler that is an improvement. If you can't figure out something GUI, work on something non-GUI. Something is absolutely better than nothing.

Not really. Arbalest links with MOOSE. Therefore, you may need to set BRLCAD_MOOSE_DIR. See the error message in your CMake configuration. It should mention it.
Daniel Rossberg (Apr 09 2024 at 06:22):The other variables are used during the MOOSE build.
Daniel Rossberg (Apr 09 2024 at 06:22):... or set automatically.

A "What do you want to do" at the top? Followed by a short help section, with the most important shortcuts ans mouse gestures? Okay, make a proposal (PR, show me your code ;).

Vidit Jain (Apr 14 2024 at 08:06):@Daniel Rossberg , I am not able to figure out anything yet..
Daniel Rossberg (Apr 14 2024 at 11:36):Okay, three points:
- Fork arbalest on github.
- Create a branch in your fork, derived from the main branch, for your development.
- After pushing the changes to your github fork, create a pull request, which we can evaluate.
BTW, I think I know what's wrong. The cause is in a part of the code, you haven't provided yet :wink:
It is however important for you to learn, how to work with code, treat bugs, give extensive reports... Knowing this, makes it much easier to mentor you.

Himanshu (Apr 14 2024 at 14:43):As Daniel said, it will be best if you can send a PR in a separate branch. It will be easier to debug whole code instead of partial.
Himanshu (Apr 14 2024 at 17:04):I guess <a href="Ctrl+N"> might not be a good solution here since it completely relies on a link. I tested this replacing Ctrl + N with www.google.com and guess what it is able to open a tab in browser and went to www.google.com but for Ctrl+N it shows ShellExecute 'Ctrl+N' failed (error 2).

You should however create a branch for your development. Doing your changes in the main branch pollutes it and can make your fork unusable for the further development.

Okay, three points:
- Describe, what I have to do, to reproduce the crash. Does it happen at program start? Or, where do I have to click?
- Run the program in the debugger. In Visual Studio it's the green triangle. Make sure that you start arbalest with it. How does the call stack look, when the program crashes?
- Provide us your full code, not only snippets:
- Fork arbalest on github.
- Create a branch in your fork, derived from the main branch, for your development.

This is not the point (yet) in your code.
Do you remember the three points I posted here? You fulfilled the third one, which es very helpful, but didn't managed the first two. For us, the first one is very important too: Describe in detail, what you did in the program (e.g.: start the program, click in the "X" button, click on the "Y" button) and what the result was (e.g.: crash with access violation).
A bit about your code (we can move this discussion to github, if you prefer this): You introduced a helpWidgetInstance pointer, but why? It's true that if you create a new pointer variable, than it's on you to initialize it. But in this case, I would say, going without it would be the better solution. If you want to know why, look, where the real instance of HelpWidget are created.
Vidit Jain (Apr 23 2024 at 16:03):To reproduce the issue -
After setting up the arbalest properly, when you launch it debug mode, it will crash at the very beginning. This is due to the access violation.
Call stack -
HelpWidget was the last function called in the call stack so far I remember.
Yaa, I realised that creating a new pointer is not really necessary.. we can do it without creating the new pointer. I am thinking of a new approach.
While debugging the code, I realized that the approach that I was using to create the signal is working. The function that's doing that is not getting called only.

not working*
Daniel Rossberg (Apr 24 2024 at 07:26):Good to hear that you were able to get the call stack.
Regarding the pointer initialization issue: To make it work, you have to make slight changes on your logic. But first, you need to understand, how the HelpWidget is created (used). Therefore, find the lines in the original code, where the HelpWidged is created/initialized (i.e., the calls of the constructor).
Amanjot Singh (May 03 2024 at 20:13):@Vidit Jain firstly, congratulations on getting selected in Google Summer of Code 2024. During your contribution and pre contribution period @Himanshu and I will be directly mentoring you. Of course, Sean and Daniel will add their invaluable advice and suggestions. It's going to be fun working with you on new GUI of BRL-CAD.
We are now in the community bonding period. You will learn about how we will work and communicate throughout the contribution period. Remember, "proactive communication" helps solve and avoid many issues quickly and saves a lot of time. So keep the updates and conversations going here.
Vidit Jain (May 04 2024 at 06:58):Thanks a lot @Amanjot Singh @Himanshu for selecting me. I am really very excited to work with you all and learn.

Vidit Jain (May 06 2024 at 15:33):Hello mentors, actually, my end term exams are going on right now, so I am not able to contribute at the moment. Is it fine if I start contributing after 16th?
Daniel Rossberg (May 07 2024 at 07:19):The official coding period starts at May 27th. Therefore, it is okay. You should however start discussing with your mentors earlier, e.g. about your PR, to get into the "flow".

Amanjot Singh Himanshu
You have to add the .cpp file inside CMakeLists.txt to add it into the build process.
Vidit Jain (May 24 2024 at 03:30):What about .h files?
Himanshu (May 24 2024 at 03:32):Vidit Jain said:

You don't have to explicitly list header files.
Himanshu (May 24 2024 at 03:34):CMake manages dependencies and its primary focus on building executables and libraries from source files. Header files are included by source files, and the compiler automatically processes them as part of the source file compilation. So, header files don’t need separate compilation rules.
Himanshu (May 24 2024 at 17:14):@Vidit Jain what's the current progress?

Did you find the places where HelpWidget will be created?
Vidit Jain (May 25 2024 at 13:25):What do you mean by places?
Vidit Jain (May 25 2024 at 13:26):Helpwidget is rendering at the start of application. Thats the only place where I can see it
Himanshu (May 25 2024 at 13:30):I mean where the connection between ctrlNPressed() and newFile() can be made there.
Vidit Jain (May 25 2024 at 13:56):So my was when Ctrl+N will be clicked, it will create a signal and the MainWindow.cpp will catch it and will execute a functin which it already has which is newFile, but the signal is not emitting only and there is no connection that's getting established :(.. there are no logs in terminal so I can't figure out anything while even debugging

If you want to see logs in terminal. Use qDebug() << "Check"; and include QDebug. In this way, you can check if a connection is made or not.
Himanshu (May 25 2024 at 14:19):@Vidit Jain okay I debugged it now and found something.
Himanshu (May 25 2024 at 14:21):I saw intro->setOpenExternalLinks(true); which is set to true in HelpWidget.cpp. Making it false enables us that the QLabel handles link clicks internally rather than delegating them to the system's default web browser.
Himanshu (May 25 2024 at 14:23):When setOpenExternalLinks is set to true, the QLabel opens the link in an external web browser, bypassing the linkActivated signal and preventing our custom slot from being called.
Himanshu (May 25 2024 at 14:24):@Vidit Jain Now your code will work as expected I guess because I guess so far you have already made the connection.
Himanshu (May 25 2024 at 14:26):For your reference setOpenExternalLinks QLabel Class | Qt Widgets 5.15.17

Daniel Rossberg (May 25 2024 at 16:29):Okay, a first review. @Vidit Jain, I start always with a look at formal things. There I see, that you mixed stylistic with functional changes. You should not do this. Create separate pull requests for stylistic and functional changes. Because your PR is about adding new functionality, you should revert all stylistic/white space changes.
Himanshu (May 25 2024 at 19:35):@Vidit Jain I want something you to move that connect inside MainWindow constructor to HelpWidget constructor. So that HelpWidget takes its parent widget as a parameter in its constructor, and the signal-slot connection is made within the HelpWidget itself. This makes HelpWidget more self-contained and easier to manage.
Himanshu (May 26 2024 at 05:55):@Vidit Jain I made a review on your PR. Make those changes and then we can focus on next things.
Himanshu (May 26 2024 at 06:03):@Daniel Rossberg Since MainWindow::newFile() is private. So how we are going to connect inside HelpWidgetconstructor so that it can call newFile() whenever Ctrl+N is clicked?

Of course, we have to use the SIGNAL and SLOT macros then, as I did in my example. (Okay, which isn't correct to, because I omitted the parameters of the signal and slot.)

Yes, it works, but it could do better. E.g., show all regions on the ray (in a dialog box?), and highlight the selected regions in the graphics view.
Himanshu (May 29 2024 at 04:52):@Vidit Jain You can also start on after selecting the primitive there should be an option to resize the primitive too. This idea is also good.

Daniel Rossberg (Jun 01 2024 at 12:28):@Vidit Jain: See my first comment in https://brlcad.zulipchat.com/#narrow/stream/111975-Google-Summer-of-Code/topic/New.20BRL-CAD.20GUI/near/441078691
Beside this, it looks okay.
Himanshu (Jun 01 2024 at 13:37):If we are removing that default constructor from HelpWidget then I see creating HelpWidget object by dynamically casting from documentArea will be useless. Here in this code:
connect(helpAct, &QAction::triggered, this, [this](){
HelpWidget * helpWidget = dynamic_cast<HelpWidget*>(documentArea->widget(0));
if (helpWidget== nullptr){
documentArea->insertTab(0, new HelpWidget(this), "Quick Start");
}
documentArea->setCurrentIndex(0);
});
Hmm, can you explain this in more detail? A cast doesn't create an object, and it seems to work well without the default constructor. Removing it shall prevent accidentally calling it.

So that portion of code looks like after removing casting,
connect(helpAct, &QAction::triggered, this, [this](){
documentArea->insertTab(0, new HelpWidget(this), "Quick Start");
documentArea->setCurrentIndex(0);
});
So whenever we are going to create new HelpWidget we have to pass an object of type QWidget.
Daniel Rossberg (Jun 02 2024 at 20:49):I still don't get it. The cast is to test, if there is a help widget in documentArea, and if there is one, if the first one is the help widget. If there is no help widget in documentArea, one will be created. This ensures that there is one help widget and it is the first one (index 0). Your code would always create a new help widget, ending up with many of them in the document area.
Passing this (which is of type MainWindow) ensures, that the correct actions will happen, if the user clicks on a link.

Oh, I understand now. That we need to check if already there is a Quick Start tab opened.

What should I work on next? I have these two options in my mind. Firstly, I noticed a bug with select primitive feature. It's not getting off when we are either changing or closing a document. Is it supposed to work like this, or is it a bug. Or I can start working on improving the same. There are some glitches going on in there.

Yes, that select primitive button remains active even after document gets closed. I saw this problem during my gsoc time.

I have fixed everything in this commit
Hmm, MainWindow.h has still the
#include "HelpWidget.h".And in HelpWidget.h:
- Line 11: There is no default constructor anymore
- Line 12: Is it really a good idea, to default the parent with the null pointer (
parent = nullptr)?
Now I understand what you asked :sweat_smile:. So if we are removing default HelpWidget constructor then in scenarios where a parent is not necessary or the widget is intended to be a top-level widget, having to always pass nullptr can be inconvenient and add verbosity to the code.
Himanshu (Jun 05 2024 at 21:30):By not providing a default nullptr value for the parent parameter, we make it mandatory for users to always specify a parent or explicitly pass nullptr, which can reduce the convenience and readability of the code.
Himanshu (Jun 05 2024 at 21:37):So we will face problem here:
connect(this, SIGNAL(ctrlNClicked()), parent, SLOT(newFile()));
connect(this, SIGNAL(ctrlOClicked()), parent, SLOT(openFileDialog()));
My point is that we think that every HelpWidget is a child of MainWindow. By not providing a default constructor for HelpWidged, the compiler will complain whenever this assumption isn't fulfilled.
In a previous version, parent was tested for nullptr. Then, I wanted a cast to be changed to the SIGNAL and SLOT macros ... but not the test for nullptr to be removed. It was however removed, but because we provide parent explicitly, I don't consider this as a problem. BTW, how does connect() handle nullptr?
Vidit Jain (Jun 06 2024 at 08:38):I have updated my pr here
Daniel Rossberg (Jun 06 2024 at 09:02):Thanks, I'll have a look at it.

Vidit Jain (Jun 08 2024 at 10:49):@Daniel Rossberg @Himanshu the approach I am thinking to fix this bug is by emmiting a signal from wherever the document is getting its id.

I was busy in some other work. I will check your PR by today or tomorrow.
Himanshu (Jun 14 2024 at 12:46):@Vidit Jain There is some inconsistency in setChecked() when I switch tabs.
What I found:
select button, now you see checked is true and button is active. Now I open another .g file and I saw that the select button have checked to false which is fine. But when I switch back to previous .g file, the button is active and it's working when I select any object but the button UI itself is turned off because you setChecked(false). So the button is still active but button UI shows it's off. Himanshu (Jun 14 2024 at 12:47):Only doing setChecked(false) when document is changed is not going to work because the button still remains active showing select button UI to off.
Himanshu (Jun 14 2024 at 12:48):@Daniel Rossberg Btw which behavior you suggest for select button when we switch tabs? So that we can implement that behavior for select button.

Is your taskbar hided in windows? Then turn it off. Or make that arbalest window size down by clicking on the maximize button. This way works for me.

Yes, the select button stays active even if I switch to another document. So what will happen to that another document that I switched?

I was trying to look to get the feature running as mentioned but I am not able to figure out whats going wrong, If @Daniel Rossberg @Himanshu have any idea what's wrong then can you please help me with that.
Himanshu (Jun 20 2024 at 12:24):We wanted to make sure that select button UI stays active even after document or tab is changed once select button is clicked. So your PR does opposite. The select button UI remains off after a tab is changed. So make sure to make it active and select is working even after tab is changed.
Daniel Rossberg (Jun 23 2024 at 13:09):@Vidit Jain, you have to understand, what the select-object-action selectObjectAct does. E.g., it uses the activeDocumentId and it calls selectObjectButtonAction() or moveCameraButtonAction(), which use the activeDocumentId too.
Vidit Jain (Jun 23 2024 at 14:12):Ya, I got that, but the thing is, I am not able to figure out why it is not always working. The logic I am seeing there seems fine, but it does not always work..
Vidit Jain (Jun 23 2024 at 14:13):The original behavior of the button exactly matches the behavior you are expecting..
Daniel Rossberg (Jun 23 2024 at 15:03):Probably, the structures have to be updated with the current activeDocumentId, which changes when the document changes.
Himanshu (Jun 26 2024 at 15:50):@Vidit Jain Did you tested your PR? Why there is two connect when document is changing? Btw when the select button is off, I saw it still calls two connects when a document is changed and calls selectObjectButtonAction() and then moveCameraButtonAction().
Himanshu (Jun 26 2024 at 15:51):I will test your PR after some time, I just checked the code only.

The code is working fine. I have added these two connects because that was the only way I could figure out to make it work.
Vidit Jain (Jun 30 2024 at 03:08):@Daniel Rossberg , I have updated my pr. The problem we are facing is that in the selectObjectAct, the activeDocumentId is not updating automatically. That's why we have to use another connect. If you have any better alternative to that, we can use that.
Vidit Jain (Jun 30 2024 at 03:10):Also, I have noticed this bug that, until we are not clicking the focus button (which is present right to the name of object), we are not able to select the primitive and once we are clicking on that, then after only we are able to start using it. Is this a bug or this is how it is supposed to work?

I suggested this way to Vidit because I thought that in future if we are creating many buttons where its state should be active even if document is switched. So that for every document change(when we switch tabs), we will check what buttons are active so that we can again call those button functions.
Himanshu (Jun 30 2024 at 09:32):For now, select button is implemented for documents but if we going for any other buttons, we can do same for those buttons too.
Daniel Rossberg (Jun 30 2024 at 14:42):Hmm, why haven't you made a slot function from updateSelectObjectState? This function could be simply called from onActiveDocumentChanged().

Himanshu (Jul 02 2024 at 21:25):@Daniel Rossberg @Vidit Jain I created a patch for the above issue. Let me know what you guys think.
Changes-On-64ac3f.patch
Himanshu (Jul 02 2024 at 21:41):So what I did:
bool moveObjectEnabled = false; in Display.h.setMoveCameraMouseAction() was called inside DisplayGrid::DisplayGrid(Document* document). Now setMoveCameraMouseAction() is removed from there. So every time we change a document or switch, connect(documentArea, &QTabWidget::currentChanged, this, &MainWindow::updateMouseButtonObjectState); will be used now and inside MainWindow::updateMouseButtonObjectState, it is already calling setMoveCameraMouseAction(). I change it like to this way to suit for new changes because once a document is created or switched, setMoveCameraMouseAction() being called for 2 times so we are allocating and deallocating memory. So I thought to go this way. Himanshu (Jul 02 2024 at 21:52):Previously also 2 times memory is being allocated and deallocated for move action.

The approach that I am planning is, I will be painting the selected object again that has been selected by the select object button. In SelectMouseAction.cpp, its returing m_selected.. I am planning to paint over it with different color and increse the width of the paint
Vidit Jain (Jul 06 2024 at 11:17):I am not sure, how can I draw over the selected region? Is there any internal BRL-CAD stuff that we have to use to paint over it?
Daniel Rossberg (Jul 06 2024 at 14:03):The rendering is done in the arbalest code. The GeometryRenderer class is a good start point to learn it.
However, you need a geometric representation of the selected object as a VectorList, which can be generated with BRLCAD::ConstDatabase::Plot().
Vidit Jain (Jul 07 2024 at 09:07):How can I get FullobjectPath to rerender it? @Daniel Rossberg @Himanshu if you have any idea?
Daniel Rossberg (Jul 07 2024 at 11:53):The result of the SelectMouseAction (getSelected()) is in fact not only a region but its full path. I.e., you have it it DisplayGrid::setSelectObjectMouseAction(). With document->getObjectTreeWidget()->select(regionName) the tree widget is adjusted to it. Now, you need something similar for the graphics.

Vidit Jain (Aug 09 2024 at 16:58):@Daniel Rossberg Can you pleasae tell me in a little brief what all functions I am suppose to use from DisplayManager.. I am trying to do so.. but I am not able to figure out why the re-rendered part not visible.
Daniel Rossberg (Aug 09 2024 at 17:04):The basic OpenGL widgets are of type Display (derived from QOpenGLWidget). If they shall refresh their content, paintGL() will be called. This function calls render() from GeometryRenderer, which again uses the functions provided with DisplayManager.
The idea was to add functions to DisplayManager, which set and clear a BRLCAD::VectorList. Then, this vector list will be drawn after the usual objects by GeometryRenderer::render().
To set and clear the vector list by SelectMouseAction, m_watched->getDisplayManager() could be used there.
Himanshu (Aug 11 2024 at 20:03):@Daniel Rossberg @Vidit Jain Is this the way we should proceed? I wrote a template like this.
void DisplayManager::setVectorList(const QString &objectFullPath, BRLCAD::VectorList *vectorList) {
display.getDocument()->getDatabase()->Plot(objectFullPath.toUtf8(), *vectorList);
display.getDisplayManager()->setFGColor(1.0f, 1.0f, 0.0f, 1.0f); // Set color to yellow
/*
Do something that new vector list will be drawn after the current objects by GeometryRenderer::render().
*/
display.update();
}
void DisplayManager::clearVectorList(BRLCAD::VectorList *vectorList) {
vectorList->Clear();
}
The structure looks fine to me
Daniel Rossberg (Aug 12 2024 at 15:49):I'm afraid, this won't do it. To take effect, QOpenGLWidget::paintGL() or a function called inside has to be touched. E.g.
void GeometryRenderer::render() {
document->getDisplay()->getDisplayManager()->saveState();
if (!objectsToBeDisplayedIds.empty()) {
for (int objectId : objectsToBeDisplayedIds) {
if (!objectIdDisplayListIdMap.contains(objectId)) {
drawSolid(objectId);
}
visibleDisplayListIds.append(objectIdDisplayListIdMap[objectId]);
}
objectsToBeDisplayedIds.clear();
}
for (int displayListId : visibleDisplayListIds) {
document->getDisplay()->getDisplayManager()->drawDList(displayListId);
}
document->getDisplay()->getDisplayManager()->drawSuffix();
document->getDisplay()->getDisplayManager()->restoreState();
}
void DisplayManager::setSuffix(const BRLCAD::VectorList& vectorList) {
suffix = vectorList;
}
void DisplayManager::clearSuffix(void) {
suffix.Clear();
}
void DisplayManager::drawSuffix(void) {
drawVList(&suffix);
}
No idea if this works, but it should point to the right direction.

Nice to hear that you got closer to the solution. Some thought about your PR:
- m_selectedObjectDisplayListId is always 0. This variable is never used and not needed. You should remove it.
- SelectMouseAction::Deselect() is never called, so you can remove it?
- DisplayManager::clearSuffix() should be called to remove the selection highlighting from the screen. Maybe in the destructor of SelectMouseAction?
- In SelectMouseAction::eventFilter() you should call setSuffix() from DisplayManager only. Setting the color should be done in DisplayManager::drawSuffix(), protected with a saveState()/restoreState(). Display::forceRerenderFrame() is doing the redraw.
I am not sure about protection with saveState() and restoreState because drawSuffix() is already protected by that in GeometryRenderer::render()

Daniel Rossberg (Aug 16 2024 at 17:27):You are right: The way drawSuffix() is called does not need a saveState()/restoreState().
Himanshu (Aug 17 2024 at 18:19):@Vidit Jain There is a bug I saw now in your PR. Highlight feature doesn't work for other document. For example if I have 2 tabs opened then it doesn't work for 2nd tab. Can you check that?

I was not working on the latest commit of the arbalest, that's why the bug was there. I have shifted to the latest commit now and its working perfectly fine now.

Vidit Jain (Aug 20 2024 at 04:20):@Daniel Rossberg @Himanshu I guess we can move to solve some different problem since we are done with the Highlight feature. Do you have some suggestions on what should I start working on after this?
Daniel Rossberg (Aug 20 2024 at 17:08):For example: https://github.com/BRL-CAD/arbalest/issues
Vidit Jain (Aug 20 2024 at 18:12):I also noticed this one bug that selectObject only works when we are focusing on it through the focus button. Without clicking on the focus button, it will not work but once you click on the focus button, it will start working.

Daniel Rossberg (Aug 20 2024 at 18:34):This could be connected to https://github.com/BRL-CAD/arbalest/issues/18. I'ts probable because the start point of the rays is behind the scene. Maybe, you can fix this.
Himanshu (Aug 21 2024 at 18:23):@Vidit Jain I reviewed your PR. Can you make some changes that I asked here https://github.com/BRL-CAD/arbalest/pull/52#pullrequestreview-2251575775
Vidit Jain (Aug 23 2024 at 10:04):@Himanshu I have updated the PR with all the suggested changes here
Vidit Jain (Aug 23 2024 at 10:07):I am thinking of starting to work on the issue . Can you please tell me where should I start from @Daniel Rossberg @Himanshu
Daniel Rossberg (Aug 23 2024 at 17:11):Can you reproduce the issue?

Daniel Rossberg I am able to produce fully ray traced image by clicking on
Reset the viewports and focus on the visiblebutton having Z-axis to 0. Screenshot-12.png
@Vidit Jain Here what I found previously for https://github.com/BRL-CAD/arbalest/issues/18. You can see my older messages, you will get some idea.
Himanshu (Aug 24 2024 at 05:57):Here is the .g file: brlcadInstall\share\db\castle.g
Himanshu (Aug 24 2024 at 06:02):Here what I got without clicking Focus on Selected Object.

Vidit Jain (Sep 01 2024 at 11:43):Hello @Daniel Rossberg ,
I was able to reproduce the issue. I was able to conclude that without centering the object, raytracing is not working properly and same is the case with select object feature. The function responsible for the same is "centerToCurrentSelection()" . I am not able to figure out the reason for the same. Can you please help.
Daniel Rossberg (Sep 02 2024 at 13:51):The ray-trace is done in RaytraceView::UpdateImage(). There, m_transformation mediates between two coordinate systems: The dot-matrix-system of the screen and the model-coordinate-system of the geometry.
For example:
QVector3D imagePoint(column, h - row - 1., 0.);
QVector3D modelPoint = m_transformation.map(imagePoint);
...
ray.origin.coordinates[0] = modelPoint.x();
ray.origin.coordinates[1] = modelPoint.y();
ray.origin.coordinates[2] = modelPoint.z();
The ray-trace is done with BRL-CAD in the model-coordinate-system. The start point of a ray is modelPoint. Its coordinates were determined from imagePoint, a point in the dot-coordinate-system of the screen. (Why is the y-coordinate reversed? Find it out ;) But, why is the z-coordinate 0?
To understand its consequences, you have to determine the direction of the ray:
QVector3D directionStart = m_transformation.map(QVector3D(0., 0., 1.));
QVector3D directionEnd = m_transformation.map(QVector3D(0., 0., 0.));
i.e., the direction of the ray is in the virtual z-direction of the screen, in -z direction.
Until here, there is no good reason, why there should be no geometric objects with positive z coordinate, when transferred to the screen coordinate system - which produces the raytracing issue.
Now, OrthographicCamera::centerToCurrentSelection() comes into play. This ends up in a transformation, which centers(?) the geometry around the origin ... this wouldn't be very helpful ... but wait, where is it created:
The transformation is created in RaytraceView::raytrace(), with a lot of reasonable operations - and a
transformation.translate(0, 0, 10000);
This looks like a shift on the z-axis with the hope, that this will move all geometric objects behind the screen's z=0 plane. I wouldn't be so optimistic that this will always be the case.
Can you follow my argumentation until here?
Vidit Jain (Sep 08 2024 at 11:40):Hello, I have created a Medium post as my GSOC final Submission.. You all can read it here
Vidit Jain (Sep 29 2024 at 21:55):Hello @Daniel Rossberg @Himanshu , I have finally successfully completed my GSOC. It’s been an incredible experience, and I’m truly grateful for the opportunity to work with such amazing mentors. I’ve learned so much throughout this journey, and I couldn’t have done it without your guidance and support.
Looking forward to continuing my contributions to Arbalest. Thank you all so much!
