Sean (Dec 01 2017 at 15:01):

@Naseef er, starting new thread here ...

Naseef (Dec 01 2017 at 15:01):

Okay

Sean (Dec 01 2017 at 15:02):

for what it's worth, appleseed integration is one of the more important task sets in our list .. there's currently 4 coding tasks there, and once those are done we have a whole bunch more

Naseef (Dec 01 2017 at 15:03):

I'd like to all of those.

Naseef (Dec 01 2017 at 15:25):

I think I can claim the appleseed task again after current one is approved. Until that, I'm gonna work on getting appleseed to compile.

Sean (Dec 01 2017 at 15:26):

okay, no rush or worries if you want to work on other stuff too -- I'm just very excited about that one in particular as we've been working with the appleseed developers for a couple years on this project

Sean (Dec 01 2017 at 15:27):

and they just provided the hooks that we need last week

Sean (Dec 01 2017 at 15:27):

so this is very much real active development research / implementation

Naseef (Dec 01 2017 at 15:28):

I'm following this guide on building appleseed : https://github.com/appleseedhq/appleseed/wiki/Building-appleseed-on-Linux
Do you think it's out of date?

Sean (Dec 01 2017 at 15:29):

Do you think it's out of date?

Sean (Dec 01 2017 at 15:29):

Nope, Franz updated that just last week

Naseef (Dec 01 2017 at 15:30):

Okay I'm going to start again from the beginning.
Hope this time it'll compile correctly.

Naseef (Dec 01 2017 at 15:34):

pasted image Everything is perfect now...

Looks like I have to install PythonLibs. I think I'll be able to find it in apt.

Naseef (Dec 01 2017 at 15:48):

Should I install libpython3.0 or libpython3.5?

Naseef (Dec 01 2017 at 15:52):

or 2.7?

Naseef (Dec 01 2017 at 15:53):

Found it in CMakeList line 570

Is that a part of this challenge?

Naseef (Dec 01 2017 at 16:01):

I'll try again after an update.

Naseef (Dec 01 2017 at 16:07):

after 'apt update', It works!

Sean (Dec 01 2017 at 16:07):

woo hoo!

Naseef (Dec 01 2017 at 16:08):

I mean the 'apt install'

Naseef (Dec 01 2017 at 16:08):

next task is 'BUILDING APPLESEED'

Naseef (Dec 01 2017 at 16:12):

Apparently the cmake is successful this time.

Naseef (Dec 01 2017 at 16:12):

Should I install the missing stuff and run CMake again?

Sean (Dec 01 2017 at 16:13):

do their docs indicate qt4 or qt5?

Naseef (Dec 01 2017 at 16:14):

You will need Qt 4.8 (or later in the 4.x series)

Important: appleseed will not build using Qt 5.x or later, you do need a 4.x version of Qt.

Sean (Dec 01 2017 at 16:14):

okay, that's good then

Naseef (Dec 01 2017 at 16:15):

I'm going to install Doxygen and QtOpenGL anyway. Just for satisfaction.

Naseef (Dec 01 2017 at 16:17):

If I didn't, for every problem coming next, I'll blame on myself for not install these.

Naseef (Dec 01 2017 at 16:21):

Well, I probably wouldn't need doxygen.

Sean (Dec 01 2017 at 16:21):

wouldn't hurt but probably not

Sean (Dec 01 2017 at 16:22):

if you make progress, you'll want to join appleseed's Slack channel so you can get help from their developers

Sean (Dec 01 2017 at 16:22):

that'll be better than reading doxygen

Naseef (Dec 01 2017 at 16:22):

I need a @appleseed mail to join

Naseef (Dec 01 2017 at 16:22):

finally executed 'make'

Naseef (Dec 01 2017 at 16:25):

my pc can't handle make and chrome at the same time, probably low memory. Currently it's 4% completed. Thanks for your help @Sean

Sean (Dec 01 2017 at 16:25):

I'll ask them about that -- I think if you post to their forum, they can invite you

Naseef (Dec 01 2017 at 17:00):

I'll try it.

Naseef (Dec 01 2017 at 17:01):

The build process is taking over my pc

Naseef (Dec 01 2017 at 17:01):

memory usage swings around 30% to 99%

Naseef (Dec 01 2017 at 17:02):

It's 40% done now.

Naseef (Dec 01 2017 at 17:11):

Now I have to run it again from the beginning :(

Sean (Dec 01 2017 at 17:12):

it may take a few attempts

Sean (Dec 01 2017 at 17:12):

if you run make VERBOSE=1 it should give a more detailed message about what it ran and what failed

Naseef (Dec 01 2017 at 17:13):

Okay, I'll try to run it again.

Sean (Dec 01 2017 at 17:13):

you don't need to start over, just run make VERBOSE=1 after it stops

Sean (Dec 01 2017 at 17:13):

it will pick up where it stopped

Sean (Dec 01 2017 at 17:14):

verbose mode produces a LOT of output, so you don't usually want to run that from a beginning of a compile

Naseef (Dec 01 2017 at 17:14):

That's what I'm going to do, The console windows was still open.

Naseef (Dec 01 2017 at 17:15):

I wonder if anyone ever built appleseed on Ubuntu 16.04 :thinking_face:

The same error again!

Naseef (Dec 01 2017 at 17:17):

kind of*

Naseef (Dec 01 2017 at 17:18):

I'll ask the appleseed guys over slack.

Sean (Dec 01 2017 at 17:19):

ouch

Naseef (Dec 01 2017 at 17:19):

maybe I should do it from the beginning again.

Sean (Dec 01 2017 at 17:19):

no

Naseef (Dec 01 2017 at 17:20):

It just takes 30 mins to come to this point.

Sean (Dec 01 2017 at 17:20):

so first rule of development, nothing is black magic .. starting over without changing anything shouldn't result in a change

Sean (Dec 01 2017 at 17:20):

that's an illegal instruction

Sean (Dec 01 2017 at 17:21):

that usually means some sort of compiler incompatibility

Naseef (Dec 01 2017 at 17:21):

GCC?

Naseef (Dec 01 2017 at 17:21):

update gcc?

Sean (Dec 01 2017 at 17:21):

so that could be the issue -- what did their build instructions say

Sean (Dec 01 2017 at 17:21):

they may require compiling with clang

Sean (Dec 01 2017 at 17:21):

or a newer version of gcc

Naseef (Dec 01 2017 at 17:21):

I just ran make.

Sean (Dec 01 2017 at 17:22):

so you didn't follow the instructions and it didn't work? :)

Naseef (Dec 01 2017 at 17:22):

4.8

Sean (Dec 01 2017 at 17:22):

look for build instructions

Naseef (Dec 01 2017 at 17:23):

It said 4.8 and I have 5.4

Naseef (Dec 01 2017 at 17:23):

So I thought it'll work.

Sean (Dec 01 2017 at 17:23):

request your invite and join their #dev

Naseef (Dec 01 2017 at 17:24):

Naseef (Dec 01 2017 at 17:24):

do I really have to read "User Terms of Service"?

Mitesh (Dec 04 2017 at 07:44):

hi everyone
i am facing one issue in the first task of appleseed and brl cad:

i used this to make an .obj file.
$ g-obj -o sample.obj sample.g sample_object

when i import it in appleseed studio and started rendering i got only pink screen and no object....

is there any mistake in my steps?

thank you

Naseef (Dec 04 2017 at 11:17):

I setup the scene with blenderseed. franz helped me.
pasted image

Mitesh (Dec 04 2017 at 12:23):

Ya he asked me to take help from you...thanks buddy,

Mitesh (Dec 05 2017 at 11:13):

can you tell me how to setup blenderseed...i have installed blender

Sean (Dec 05 2017 at 18:55):

It’s fine to use blenderseed but that is not a solution relevant to any of the GCI tasks ...

Sean (Dec 05 2017 at 18:56):

For the first task for example, that’s more about export and import knowing the minimal of both so you can do the next tasks

Sean (Dec 05 2017 at 18:57):

The following tasks can all be done with that simple sphere import wh ch doesnt require blenderseed

Naseef (Dec 05 2017 at 19:01):

Yeah, Wait, I'll give you a link...

Naseef (Dec 05 2017 at 19:01):

Are you getting my messages?

Naseef (Dec 05 2017 at 19:01):

Looks like there is a network error.

Naseef (Dec 05 2017 at 19:02):

Oh yeah, There was a network error.

Mitesh (Dec 10 2017 at 15:49):

I am on appleseed task2# and I am trying to run this on visual studio:
http://brlcad.org/wiki/Example_Application

but I am getting these errors. Can you please help me out...errortask2.PNG

Mitesh (Dec 10 2017 at 15:54):

I did this to include header files of brlcad:-Capture1.PNG
Is this correct?

Daniel Rossberg (Dec 10 2017 at 16:05):

Hmm, the first thing I'm seeing is that you created a C++ file from the example application. Although C code can usually be easily transferred to C++ it's not guaranteed. There are small differences in the conventions.
Therefore, how does it behave when you compile it as C (Source.c or rtexample.c)?

Daniel Rossberg (Dec 10 2017 at 16:07):

And naturally, you need to set-up the BRL-CAD environment in your Visual Studio project with include and library folder etc..

Mitesh (Dec 10 2017 at 16:12):

ok..
for setting up environment I did this:
project menu--> Project properties ---> c/c++ ---> Additional include directories---> Added include and libraries folder of brlcad

is it ok?

Mitesh (Dec 10 2017 at 16:13):

environment.PNG

Mitesh (Dec 10 2017 at 16:15):

also i change the extension from .cpp to .c

Mitesh (Dec 10 2017 at 16:21):

From the above settings I am getting this:LNK.PNG

Daniel Rossberg (Dec 10 2017 at 16:27):

ok..
for setting up environment I did this:
project menu--> Project properties ---> c/c++ ---> Additional include directories---> Added include and libraries folder of brlcad

is it ok?

I think the BRL-CAD include directory is H:\brlcad_install\include\brlcad which means that the additional include directories are

• H:\brlcad_install\include
• H:\brlcad_install\include\brlcad
• H:\brlcad_install\include\openNURBS

H:\brlcad_install\lib is not an include directory. This folder needs to be set in "Linker" as the directory where it should search for additional libraries.

Daniel Rossberg (Dec 10 2017 at 16:28):

In addition, you have to set in "Linker" the BRL-CAD libraries libbu, libbn, librt, and some more.

Mitesh (Dec 10 2017 at 16:43):

I have added the lib folder to "linker additional library directories"
but can you please tell me how to set in linker libraries libbu, libbn, libbrt etc.
Should it be added in same "linker additional library directories"

Daniel Rossberg (Dec 10 2017 at 16:54):

No. There should be a simple "additional libraries" or similar somewhere.

Mitesh (Dec 10 2017 at 16:56):

additional dependencies?

Mitesh (Dec 10 2017 at 16:57):

addlibraries.PNG

Daniel Rossberg (Dec 10 2017 at 17:14):

Looks good.

Mitesh (Dec 10 2017 at 17:16):

when I click to edit it I get this screenadd1.PNG

Mitesh (Dec 10 2017 at 17:17):

should I simply write "libbn.lib" and press enter or should I enter the file with its directory?

Daniel Rossberg (Dec 10 2017 at 17:23):

You shouldn't add the path (directory) here. You already set it in the other dialog field.

Mitesh (Dec 10 2017 at 17:24):

okk...thank you so much...will update he result after I make changes:).

Mitesh (Dec 10 2017 at 17:43):

notfound.PNG
got this error

Mahdi (Dec 10 2017 at 17:48):

That's probably because your executable can't locate your .dll file. Try moving the dll to the same directory as the .exe

Mitesh (Dec 10 2017 at 17:56):

Thanks there are no errors but only something like this:
empty.PNG

Mitesh (Dec 10 2017 at 17:58):

okk gotit...the ray is in model.g...right?

Mitesh (Dec 10 2017 at 18:04):

wait there is no model.g....

Mitesh (Dec 10 2017 at 18:14):

something's wrong ?

Mitesh (Dec 10 2017 at 18:16):

I should also place a .g with altleast one obj file with the .exe file.
Am I right or wrong?

Daniel Rossberg (Dec 10 2017 at 18:26):

In the project setting there is a "Debug" entry. There you can set the arguments. Set a BRL-CSAD geometry .g file there, and make sure that the program will find it.

Mitesh (Dec 10 2017 at 18:34):

you mean command arguements?Commandarg.PNG

Daniel Rossberg (Dec 10 2017 at 18:52):

Yes.

Jeff Sieu (Dec 11 2017 at 05:31):

I'm getting this error, is it something to do with my computer? pasted image

Mitesh (Dec 11 2017 at 13:14):

Mitesh (Dec 11 2017 at 13:15):

Please tell me where am I making mistake.

Daniel Rossberg (Dec 11 2017 at 13:25):

You have to set there only the arguments, not the program itself. And, make sure the program can find the given .g file.

Mitesh (Dec 11 2017 at 13:26):

when i add only "sphere.g" in the command argument i get only this statement "usage: C:\....."
Can you pls tell me how to make sure that program can find the given .g file

sphere.g has to be in the working directory of the program. Or, you could give the full path as parameter.

Mitesh (Dec 11 2017 at 13:31):

The "sphere.g" is in the working directory of program but i get the same thing:

Daniel Rossberg (Dec 11 2017 at 13:39):

OK, what else says the usage statement?

Mitesh (Dec 11 2017 at 13:41):

Sorry I didn't get you..Do you mean what other changes give usage statement?

Mitesh (Dec 11 2017 at 13:43):

if I add sphere.g at the end of $(TargetPath) in command tab I get the same statement

Daniel Rossberg (Dec 11 2017 at 14:08):

What I meant was: What says the usage statement? Did you read it? What parameters expects the program?

Mitesh (Dec 11 2017 at 14:16):

Capture6.PNG

Daniel Rossberg (Dec 11 2017 at 14:31):

And? Do you see any discrepancy between the required parameters and the parameter you gave?

... Sorry, the model.g is in the usage statement.

Mitesh (Dec 11 2017 at 15:47):

Capture7.PNG capture8.png
What I think is that rtip must not be null and for that there must be some value for argv[1] and title...
am i right?

Daniel Rossberg (Dec 11 2017 at 15:49):

How does this answer my question?

Daniel Rossberg (Dec 11 2017 at 15:50):

What is the minimum number of parameters the program requires?

Daniel Rossberg (Dec 11 2017 at 15:51):

In Capture6.PNG you marked some lines, but have you read them?

Mitesh (Dec 11 2017 at 15:54):

okk its 2

Daniel Rossberg (Dec 11 2017 at 15:55):

Right. One is the file name, and the other one(s)?

Mitesh (Dec 11 2017 at 15:55):

so its should be a .g as well as .obj file? right?

Daniel Rossberg (Dec 11 2017 at 15:57):

No. What are the objects in a BRL-CAD database?

Mitesh (Dec 11 2017 at 15:57):

sphere sph

Daniel Rossberg (Dec 11 2017 at 15:59):

I don't know your geometry but if you have called your sphere "sphere" then that is it.

Mitesh (Dec 11 2017 at 16:00):

I have one question....we have already included the brlcad database so doesn't that mean that object is also included by default?

Daniel Rossberg (Dec 11 2017 at 16:01):

There is no default object in a BRL-CAD database.

Mitesh (Dec 11 2017 at 16:02):

okk....so how should i add the object now?

Daniel Rossberg (Dec 11 2017 at 16:02):

Usually you have many objects in a .g file, even more then one top object. And the investigation routines can be applied to lower level objects too.

Daniel Rossberg (Dec 11 2017 at 16:03):

okk....so how should i add the object now?

Simply add its name as the second parameter.

Mitesh (Dec 11 2017 at 16:04):

okk

Mitesh (Dec 11 2017 at 16:06):

got it
result1.PNG
Thank you so much

Daniel Rossberg (Dec 11 2017 at 16:08):

Always read the fine manual - or usage statement ;)

Mitesh (Dec 11 2017 at 16:08):

ya...I should have read that

Mitesh (Dec 11 2017 at 16:25):

can we see the ray that hits the geometry?

Mitesh (Dec 11 2017 at 17:23):

I tried to understand the examples from src/rt
These are not so easy to understand for me and I think it will take some time for me.
I think I should do the 3dmodelling tasks first.

Daniel Rossberg (Dec 11 2017 at 18:54):

can we see the ray that hits the geometry?

It depends on what you mean with "see". You could set a break point in the hit() function. Then the program execution will stop always when a ray hits the geometry.

Lucas Prieels (Dec 26 2017 at 00:57):

Hi! I've compiled the rtexample.c program and I see how to modify it but I don't know at all how to write an image... Can someone help me? Thanks!

Sean (Dec 27 2017 at 06:13):

Hi! I've compiled the rtexample.c program and I see how to modify it but I don't know at all how to write an image... Can someone help me? Thanks!

@Lucas Prieels so the example just fires one ray. You need to fire a grid of rays, and then store the result in an image array. It's then really easy to write that image data out as PPM data. You basically print a 3 line text header, and then a dump of the image array bytes. There is lots of examples on the web showing this.

caleb parks (Jan 05 2018 at 04:54):

I can't seem to get anything that is imported to render in appleseed.

Sean (Jan 05 2018 at 04:54):

you need to create a light source or create an ambient lighting source

Sean (Jan 05 2018 at 04:56):

this is an environment EDF

Sean (Jan 05 2018 at 04:56):

if you join the appleseed slack channel, they can help walk you through it

Mitesh (Jan 11 2018 at 03:15):

@everyone
Has anyone reached 5th task of appleseed

Lucas Prieels (Jan 11 2018 at 06:12):

Has anyone reached 5th task of appleseed

I think that if someone succeded the 5th task, the admins would have add a 6th one

Sean (Jan 12 2018 at 16:41):

Someone is just now working on it and ... nearly successful

Lucas Prieels (Jan 12 2018 at 16:44):

Is it you @Jeff Sieu ? :joy:

Lucas Prieels (Jan 12 2018 at 22:15):

For Appleseed #4, we basically just have to compile the sphereobject.cpp file using cmake and add a std::cout << something in the intersect function, right?

Sean (Jan 13 2018 at 05:28):

basically. it would be good if you customized it a bit but the main point is to figure out how their plugins work, how the build works, etc

Sean (Jan 13 2018 at 05:28):

it's a surprisingly easy task -- surprised more didn't do it

Jeff Sieu (Jan 13 2018 at 05:34):

This is really weird. I'm able to build the plugin.cpp file which has a RENDERER_LOG_INFO("%d", bu_parallel_id()); line. But when I try to load the appleseed project file in appleseed.studio, it gives me that same error: while defining object "sphere": invalid model "brlcad_object".

Jeff Sieu (Jan 13 2018 at 05:35):

If I have a line like struct application ap; in plugin.cpp though, the project does not give any error.

Jeff Sieu (Jan 13 2018 at 05:35):

So, somehow calling any functions from BRL-CAD gives problems

Sean (Jan 13 2018 at 05:37):

@Jeff Sieu that's because of a thing called dynamic loading

Sean (Jan 13 2018 at 05:37):

notice that you are not recompiling appleseed or brl-cad

Sean (Jan 13 2018 at 05:37):

you're just compiling your plugin

Sean (Jan 13 2018 at 05:38):

the way that works is appleseed has code that says "open this library, look for this function, run it"

Jeff Sieu (Jan 13 2018 at 05:38):

right

Sean (Jan 13 2018 at 05:38):

in the plugin, there's a specifically named function that essentially registers the rest of the functions

Sean (Jan 13 2018 at 05:39):

to compile the plugin, the compiler just needs to know the names of the functions you are calling

Sean (Jan 13 2018 at 05:40):

it doesn't need to actually need the functions themselves just yet ... not until the library is loaded

Jeff Sieu (Jan 13 2018 at 05:41):

does this mean that I'll need to load the library files from brl-cad as well?

Sean (Jan 13 2018 at 05:41):

when it tries to load the library, it sees that this is a library that calls a bunch of functions, one of them being bu_parallel_id() ... and since it doesn't have the definition of that function (or know where to find it), it ends up failing

Sean (Jan 13 2018 at 05:41):

sort of

Sean (Jan 13 2018 at 05:41):

when you build the plugin, you need to tell it that the plugin depends on that library

Sean (Jan 13 2018 at 05:41):

notice the line at the bottom of the CMakeLists.txt file

Sean (Jan 13 2018 at 05:42):

that's where it tells it that the plugin depends on the appleseed libraries

Sean (Jan 13 2018 at 05:42):

so the first thing to try is simply add the other libraries your using to that list

Jeff Sieu (Jan 13 2018 at 05:45):

ohh i see

Jeff Sieu (Jan 13 2018 at 05:47):

OOH IT WORKS!!

Jeff Sieu (Jan 13 2018 at 05:48):

Thank you so much @Sean !

Sean (Jan 13 2018 at 05:48):

woo hoo!

Sean (Jan 13 2018 at 05:48):

screenshot?

Sean (Jan 13 2018 at 05:49):

did you get my other comment about not needing to shoot a grid of rays?

Jeff Sieu (Jan 13 2018 at 05:51):

did you get my other comment about not needing to shoot a grid of rays?

Yeah, so if I'm not wrong, this task is about getting BRL-CAD objects to render in Appleseed, right?

Sean (Jan 13 2018 at 05:52):

unless that's just a crazy amount of additional work, it's to at least make progress in that direction

Sean (Jan 13 2018 at 05:52):

we can make more tasks to get there, but rendering in appleseed is indeed the goal

Sean (Jan 13 2018 at 05:53):

franz added those procedural plugin hooks for us to do exactly that

Jeff Sieu (Jan 13 2018 at 05:53):

screenshot?

Well, the project file does load now. I haven't got to actually making the ray-tracing stuff to work yet because I was so frustrated. But I think now I can try to actually get it to work. Maybe I can get it done by today...

Sean (Jan 13 2018 at 05:53):

submit what you have and I'll add a step 6

Jeff Sieu (Jan 13 2018 at 05:54):

Oh okay...

Sean (Jan 13 2018 at 05:54):

well after fixing the other issues mentioned

Sean (Jan 13 2018 at 05:54):

don't need to shoot a grid, need to prep during frame setup, etc

Sean (Jan 13 2018 at 05:55):

I don't think it will suddenly all work if you do that, but it is needed regardless

Lucas Prieels (Jan 13 2018 at 05:56):

it's a surprisingly easy task -- surprised more didn't do it

Actually, the third task was easy but I had a lot of problem because I had download Appleseed a few days before they submit a patch which made it work :)

Jeff Sieu (Jan 13 2018 at 05:56):

I was thinking that it would need some basic math to translate it into the right position, because the object may be translated in Appleseed as well, on top of any translation in the .g file

Jeff Sieu (Jan 13 2018 at 06:03):

submit what you have and I'll add a step 6

Submitted

Sean (Jan 13 2018 at 06:05):

Actually, the third task was easy but I had a lot of problem because I had download Appleseed a few days before they submit a patch which made it work :)

there were lots of things that could potentially go wrong .. that's why it was a task at all ;)

Any idea @Jeff Sieu (I know you’ve done this task so I suppose you know how to do it)

Mitesh (Jan 14 2018 at 11:29):

i have one...take input of through gets(variable); and place that variable in the fuction

APPLESEED integration: Write a small C/C++ program in appleseed that renders an image (task #3 of 5)

Jeff Sieu (Jan 14 2018 at 11:33):

You simply make it read from an appleseed project file

Lucas Prieels (Jan 14 2018 at 12:19):

You simply make it read from an appleseed project file

Really? That’s enough? So I just take for example project.appleseed instead of scene.obj? I thought it was less easy :)

Jeff Sieu (Jan 14 2018 at 12:27):

Yeah

Mitesh (Jan 14 2018 at 14:00):

The fourth one is not as simple as it looks...simply adding cout<<""; won't work since sphereobject builds a plugin and not .exe and we cannot execute a plugin..

Jeff Sieu (Jan 14 2018 at 14:02):

Also, I was wondering how rt_shootray can be done in the plugin though. Seems like it's asynchronous but intersect() requires the output right away (in the case of bool intersect(), it needs to know whether it's a hit or a miss right away).

Mitesh (Jan 14 2018 at 14:07):

what is the role of intersect in plugin?

Jeff Sieu (Jan 14 2018 at 14:08):

"Compute the intersection between a ray expressed in object space and the surface of this object and return detailed intersection results."

Mitesh (Jan 14 2018 at 14:08):

and this detailed results go where?

Mitesh (Jan 14 2018 at 14:09):

I mean where are they stored?

Jeff Sieu (Jan 14 2018 at 14:09):

IntersectionResult& result

Mitesh (Jan 14 2018 at 14:09):

I mean why do we want intersect()?

Mitesh (Jan 14 2018 at 14:11):

just to check whether the ray thrown intersects or not?

Jeff Sieu (Jan 14 2018 at 14:11):

So that you'd know how to "render" the object?

Mitesh (Jan 14 2018 at 14:12):

what i thought was that if we use rt_shootray() instead of intersection?

Mitesh (Jan 14 2018 at 14:13):

am i going correct?

Jeff Sieu (Jan 14 2018 at 14:15):

No

Mitesh (Jan 14 2018 at 14:16):

why??

Jeff Sieu (Jan 14 2018 at 14:16):

By right, Appleseed should call intersect() and it's our job to replace whatever is inside intersect with the results from BRL-CAD's raytrace.

Mitesh (Jan 14 2018 at 14:17):

okk...sorry...mybad...mybad

Mitesh (Jan 14 2018 at 14:24):

hmm...now it seems..pretty hard

I had 2 tasks in advance, but they were in-progress and there wasn't enough time before the last task could be claimed so :/

comming back to topic....

Mitesh (Jan 15 2018 at 16:22):

what should i do if i don't want argc and argv?

Lucas Prieels (Jan 15 2018 at 16:23):

Why do you want to initialize them without main?

Mitesh (Jan 15 2018 at 16:24):

in sphereobject there is no main() function...it gives dll as output...but to integrate it with rtexample i need to exclude main()

Mitesh (Jan 15 2018 at 16:25):

any ideas?

Lucas Prieels (Jan 15 2018 at 16:26):

Is it possible for the plugin to print things in another file using fstream?

Mitesh (Jan 15 2018 at 16:27):

yes

Jeff Sieu (Jan 15 2018 at 16:28):

I think appleseed handles argv somewhere, but it may not be exposed to the plugin

Lucas Prieels (Jan 15 2018 at 16:28):

Sorry, forget what I was saying that can't work

Jeff Sieu (Jan 15 2018 at 16:28):

Regardless, you can simply hardcode in a database name and object name, instead of receiving them as argc and argv parameters.

Mitesh (Jan 15 2018 at 16:31):

okk...gotcha

Mitesh (Jan 15 2018 at 16:31):

thanks

Mitesh (Jan 15 2018 at 16:38):

we need argc and argv just to check whether the input databse and objects are correct or wrong...right?

Jeff Sieu (Jan 15 2018 at 16:46):

argc and argv are used as input into the rtexample program to tell it the path of the BRL-CAD database in question and the object(s) in it. In your case, these are simply unneeded as you can simply hardcode in the values as strings.

Mitesh (Jan 15 2018 at 16:48):

ok...so where there is argv or argc i should replace it with the name of database and object file

Jeff Sieu (Jan 15 2018 at 16:48):

Yes.

Mitesh (Jan 15 2018 at 16:49):

instead of argc object and instead of argv database?

Mitesh (Jan 15 2018 at 16:53):

sorry...argv[1]=database name

Lucas Prieels (Jan 15 2018 at 16:59):

Has your 4th been accepted?

Jeff Sieu (Jan 15 2018 at 23:23):

Hi I'm getting this error when trying to run the plugin, even after the initialisation of ap->a_resource: something about ptbl being a bad pointer.

Context: everything from rtexample.c is ran in the correct order in the appleseed plugin file. Used to get an error for something like null resource pointer, but fixed that by initialising it at first. Now I run into this problem. This error also only appears when rt_shootray is called.

Mitesh (Jan 16 2018 at 09:33):

This is really weird. I'm able to build the plugin.cpp file which has a RENDERER_LOG_INFO("%d", bu_parallel_id()); line. But when I try to load the appleseed project file in appleseed.studio, it gives me that same error: while defining object "sphere": invalid model "brlcad_object".

got same issue....

added this function and called it in intersect function()....am I wrong anywhere?

Mitesh (Jan 16 2018 at 16:28):

rtip = rt_dirbuild("sphere.g", title, sizeof(title));
there's something wrong in this line..

Mitesh (Jan 16 2018 at 16:29):

i have used argc=3
argv[1]="sphere.g";
argv[2]="sph";

Mitesh (Jan 16 2018 at 17:07):

infact replaced argv[1] with sphere.g and argv[2] with sph completely....in the source code

Mitesh (Jan 17 2018 at 12:27):

in which folder should I place all the .dll files?

Mitesh (Jan 17 2018 at 12:42):

@everyone any ideas?

Armin (LordOfBikes) (Jan 17 2018 at 13:15):

@Mitesh, I'm not involved with appleseed, but if you are in doubt, it should work, when you put them into the same folder with the executable

Mitesh (Jan 17 2018 at 13:50):

Thank you @LordOfBikes . . but the program generates a plugin....so should I place it in the same folder as that of plugin?

Armin (LordOfBikes) (Jan 17 2018 at 14:07):

I think you can create plugins folder in your application folder for it or use QCoreApplication::addLibraryPath().
See http://doc.qt.io/qt-5/plugins-howto.html#locating-plugins for details.

Mitesh (Jan 17 2018 at 14:08):

thank you..i will look at it

Jeff Sieu (Jan 17 2018 at 14:47):

Actually, I think you can set APPLESEED_SEARCHPATH=<dll folder>

Mitesh (Jan 17 2018 at 16:43):

@Jeff Sieu i tried setting the path...but still got the same issue...

Mitesh (Jan 17 2018 at 16:43):

@LordOfBikes is there any other way...actually i have never used QT

Mitesh (Jan 17 2018 at 16:54):

sameissue.PNG
I get this whenever I add the "rtip=rt_dirbuild("sphere.g", title, sizeof(title));" line

Mitesh (Jan 17 2018 at 16:55):

if I remove it, it works

Mitesh (Jan 17 2018 at 18:31):

any ideas?

Armin (LordOfBikes) (Jan 17 2018 at 20:28):

@Mitesh, best is you copy/paste the whole log output into a file and attach it here

Mitesh (Jan 18 2018 at 01:42):

here are the logs of the sphereobject
appleseedlog.txt

Daniel Rossberg (Jan 18 2018 at 10:08):

I don't think that adding H:\BRLCAD7.26.0\bin to APPLESEED_SEARCHPATH was a good idea, but you may tray to add this directory to your PATH environment variable. This way, every program can find the BRL-CAD DLLs.

Daniel Rossberg (Jan 18 2018 at 10:15):

Or, you could give the brlcad.dll a try: https://sourceforge.net/projects/brlcad/files/BRL-CAD%20Runtime%20Libraries/7.26.0/
Download the devel package there. Even if its strong point is the C++ interface (which would be a choice here too) it exports some C functions as well: https://sourceforge.net/p/brlcad/code/HEAD/tree/brlcad/trunk/misc/win32-msvc/Dll/brlcad.def

Daniel Rossberg (Jan 18 2018 at 10:18):

@Jeff Sieu If Appleseed really runs in parallel the semaphores in BRL-CAD have to be activated: bu_semaphore_init(RT_SEM_LAST)
BRLCAD::PrepareForMultithreading() in the C++ interface.

Mitesh (Jan 19 2018 at 02:48):

thanks @Daniel Rossberg but when I added the folder to the environment and also added brlcad.dll...I got the same issue....
applelogs.txt

Mitesh (Jan 19 2018 at 02:48):

i added brlcad.dll to the bin folder

Naseef (Jan 19 2018 at 09:39):

but it's a lib

Mitesh (Jan 19 2018 at 09:40):

it has both lib and dll....added lib to lib folder and .dll to bin folder

Naseef (Jan 19 2018 at 09:41):

.dll is also a library

Naseef (Jan 19 2018 at 09:42):

Dynamic Link Library!

Mitesh (Jan 19 2018 at 09:43):

but all the dll files are placed in BIN folder and libs are placed in lib folder... .dll is a plugin

Daniel Rossberg (Jan 19 2018 at 09:44):

i added brlcad.dll to the bin folder

You have to link your program to this DLL to, instead of linking it to the standard BRL-CAD lib~ libraries.

Naseef (Jan 19 2018 at 09:44):

You're right. That's how it works in Windows.

Mitesh (Jan 19 2018 at 09:45):

okk...got that

Mitesh (Jan 23 2018 at 08:51):

Hi everyone. I tried linking it with only brlcad.dll...but again got the same error..."while defining object sphere....."

Daniel Rossberg (Dec 14 2019 at 17:01):

@Jeffrey Liu For what I understood, you are looking for a way to write an own application using BRL-CAD libraries?

Jeffrey Liu (Dec 14 2019 at 17:23):

@Daniel Rossberg something like that - I'm working on the 5th appleseed task, which requires me to call rt_shootray() from an appleseed plugin.

Daniel Rossberg (Dec 14 2019 at 17:29):

I recommend to use another library, which already uses librt, as template. This could be done in BRL-CAD's main repository. There, you can use a copy of such a library, name it libappleseed, remove all it's source files (in the copy), put your own files in, and adapt the CMakelist.txts.

Another possibility is to put it in rt^3 (do the experimental features compilation task first). There, you can copy src/coreInterface (e.g. to src/appleseed) and use this as template for your own work.

Jeffrey Liu (Dec 14 2019 at 17:45):

Ah, thank you for the advice! I was only thinking about configuring BRLCAD externally and not internally. However, in this case, I would then need to somehow link the appleseed libraries then, right?

Daniel Rossberg (Dec 14 2019 at 17:47):

Yes, this should be possible in the usual way. I assume, you have already a configuration using the appleseed libraries.

Mayank Goyal (Dec 14 2019 at 17:53):

Before starting,I wanted to know what basically we have to do in Appleseed task #2

Daniel Rossberg (Dec 14 2019 at 18:00):

#2 refers to this example: https://brlcad.org/wiki/Example_Application
It recommends to take this one and change it such that it shoots a grid of rays. Build it and you are essentially done.

Jeffrey Liu (Dec 14 2019 at 18:04):

Yes, this should be possible in the usual way. I assume, you have already a configuration using the appleseed libraries.

I do, but the configuration for the appleseed libraries is also internal, so I think I might be facing the same difficulty one way or the other.

Daniel Rossberg (Dec 14 2019 at 18:05):

Which OS are you working on?

Jeffrey Liu (Dec 14 2019 at 18:05):

Windows

Jeffrey Liu (Dec 14 2019 at 18:07):

For now, I think I'll try linking the BRLCAD libraries into appleseed because starseeker already provided me with some references to follow.

Daniel Rossberg (Dec 14 2019 at 18:10):

For Windows, there is a "dirty" trick to link own applications with BRL-CAD: https://sourceforge.net/projects/brlcad/files/BRL-CAD%20Runtime%20Libraries/7.26.0/brlcad-7.26.0_dll_devel.zip/download
https://brlcad.org/wiki/BRL-CAD%27s_core_C%2B%2B_interface

Jeffrey Liu (Dec 14 2019 at 18:12):

Oh wow, thanks for sharing this! I hadn't come across this beforehand. If I'm not mistaken, is this basically a dll that I can place inside of the proper directory, allowing for me to call librt functions?

Daniel Rossberg (Dec 14 2019 at 18:14):

Some librt functions, but mainly the C++ interface methods. They support the ray-trace too.

Jeffrey Liu (Dec 14 2019 at 18:14):

Thank you, I'll try working with this first then.

Jeffrey Liu (Dec 14 2019 at 18:31):

@Daniel Rossberg Would something like this be correct?
include_directories (C:\Users\JeffL\Downloads\brlcad-7.26.0_dll_devel\include) target_link_libraries(brlcad)
Sorry, I'm not very familiar with CMake.

Daniel Rossberg (Dec 14 2019 at 18:32):

This doesn't look wrong. Visual Studio will tell you if it's indeed correct.

Jeffrey Liu (Dec 14 2019 at 19:03):

Alright, so I'm getting this error now when trying to compile a test:
2>LINK : fatal error LNK1104: cannot open file 'brlcad.lib' 2>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.CppCommon.targets(720,5): error MSB6006: "link.exe" exited with code 1104.
I found the location of brlcad.lib, but I don't know how to link it through CMake.

Daniel Rossberg (Dec 14 2019 at 19:05):

In the project settings in Visual Studio there is a setting for additional library directories.

Sumagna Das (Dec 14 2019 at 19:06):

yea there is a setting

Jeffrey Liu (Dec 14 2019 at 19:07):

Alright, I'll do it manually for now.

Jeffrey Liu (Dec 14 2019 at 19:07):

Well the build worked... now time to test it

Daniel Rossberg (Dec 14 2019 at 19:11):

BTW, by the same way you can link with librt etc..

Jeffrey Liu (Dec 14 2019 at 19:13):

Oh wait, so if I just link with librt through VS, do I still need to use the brlcad.dll/lib and everything? Or could I just link to the src/librt and then work from there?

Jeffrey Liu (Dec 14 2019 at 20:01):

I asked starseeker about how I might do this on the other Appleseed channel - please let me know if there would be something wrong with this method.

Sumagna Das (Dec 21 2019 at 15:51):

has anyone built appleseed from source?

Daniel Rossberg (Dec 21 2019 at 15:55):

just trying

Sumagna Das (Dec 21 2019 at 15:55):

what? building appleseed?

Daniel Rossberg (Dec 21 2019 at 15:56):

yes

Sumagna Das (Dec 21 2019 at 15:56):

it now points to osl(open shading language) which is pointing to openimageio

Sumagna Das (Dec 21 2019 at 15:56):

by pointing, i mean pointing out errors

Daniel Rossberg (Dec 21 2019 at 15:57):

Which OS are you working with?

Sumagna Das (Dec 21 2019 at 15:57):

linux

Sumagna Das (Dec 21 2019 at 15:57):

osl needs oiio 2.0 but apt offers 1.x something version

Daniel Rossberg (Dec 21 2019 at 15:58):

apt install openimageio-dev openimageio-tools

Sumagna Das (Dec 21 2019 at 15:59):

it says unable to locate package

Sumagna Das (Dec 21 2019 at 16:00):

the package is libopenimageio-dev but it offers 1.7 version

Daniel Rossberg (Dec 21 2019 at 16:02):

On Debian buster it is 2.0.5.

Sumagna Das (Dec 21 2019 at 16:03):

you are working on debian?

Daniel Rossberg (Dec 21 2019 at 16:03):

yes

Sumagna Das (Dec 21 2019 at 16:03):

does debian use dpkg?

Sumagna Das (Dec 21 2019 at 16:03):

you are working on debian?

Sumagna Das (Dec 21 2019 at 16:03):

does debian use dpkg?

Himanshu (Dec 21 2019 at 16:05):

does debian use dpkg?

yeah like sudo dpkg install ....

Daniel Rossberg (Dec 21 2019 at 16:05):

Yes, it uses this too.

Sumagna Das (Dec 21 2019 at 16:05):

but in ubuntu its different

Sumagna Das (Dec 21 2019 at 16:05):

dpkg -i or --install

Daniel Rossberg (Dec 21 2019 at 16:06):

On Debian it's rather apt install ~
Ubuntu is Debian based.

Sumagna Das (Dec 21 2019 at 16:06):

yea

Sumagna Das (Dec 21 2019 at 16:11):

btw, if i upgrade from 18.04 to 19.04, will it do anything to my data or the a data on the windows partition of this laptop?

Sumagna Das (Dec 21 2019 at 16:12):

i know its a LTS but openimageio is present on that one as version 2.0.5

Sumagna Das (Dec 21 2019 at 16:13):

link

Sumagna Das (Dec 21 2019 at 16:13):

see?

An upgrade should not touch your data (e.g. what ever is in the /home directory), but it may require some reconfiguration to get back the old behavior.

Sumagna Das (Dec 21 2019 at 17:47):

ok

Daniel Rossberg (Dec 21 2019 at 17:59):

I had just a fight with OpenShadingLanguage. This build.patch made it build.

Daniel Rossberg (Dec 22 2019 at 16:32):

I found no way to build appleseed on Linux.

Sumagna Das (Dec 23 2019 at 08:14):

Me too but trying

Daniel Rossberg (Dec 23 2019 at 12:17):

I found no way to build appleseed on Linux.

Now, after some days trying, I finally succeeded. If anybody has questions regarding building Appleseed on Linux, feel free to ask.

There is a wiki page about this: https://github.com/appleseedhq/appleseed/wiki/Building-appleseed-on-Linux
However, I didn't found it helpful, except what it says about PYTHONHOME in the last section.

Sumagna Das (Dec 23 2019 at 12:18):

i couldnt even build it completely

Sumagna Das (Dec 23 2019 at 12:18):

it stopping somewhere or the other

Sumagna Das (Dec 23 2019 at 12:20):

i even had to upgrade the whole os from an LTS to a normal version (which i am now regretting)

Sumagna Das (Dec 23 2019 at 12:27):

from 18.04 to 19.04

Sumagna Das (Dec 23 2019 at 12:42):

these errors are coming for which i am rebuilding with some extra options but what are these errors and how to fix them if they come back

Daniel Rossberg (Dec 23 2019 at 13:04):

In appleseeds CMake settings (use the cmake-gui), there is an entry for boost static (serach for these two words to find the actual name). Switch it to OFF, and the boost error schould have been gone.

Then, did you installed Open Shading Language?

Sumagna Das (Dec 23 2019 at 14:02):

i didnt install osl but used the libraries from the prebuilt ones

Sumagna Das (Dec 23 2019 at 14:02):

btw my cmake-gui is not working

Sumagna Das (Dec 23 2019 at 14:02):

sayin segmentation fault(core dumped)

Sumagna Das (Dec 23 2019 at 14:10):

trying to build appleseed again

Sumagna Das (Dec 23 2019 at 14:10):

i had to install cmake-qt-gui

Sumagna Das (Dec 23 2019 at 14:23):

its building and btw boost static was already off

Daniel Rossberg (Dec 23 2019 at 14:34):

Did you installed libboost-all-dev?

Sumagna Das (Dec 23 2019 at 14:36):

Sumagna Das (Dec 23 2019 at 14:36):

Sumagna Das (Dec 23 2019 at 14:36):

many of the packages are reporting this so what should i do?

Daniel Rossberg (Dec 23 2019 at 14:37):

Is synaptic installed?

Sumagna Das (Dec 23 2019 at 14:38):

yea

Daniel Rossberg (Dec 23 2019 at 14:38):

You could also try apt install libboost-all-dev

Daniel Rossberg (Dec 23 2019 at 14:38):

yea

Then start it, and use this to install libboost-all-dev.

Sumagna Das (Dec 23 2019 at 14:39):

sudo aptitude install libboost-all-dev

Sumagna Das (Dec 23 2019 at 14:39):

Sumagna Das (Dec 23 2019 at 14:39):

hi. was trying to run rtexample.c in visual studio 15. I have added the folders of header files in "additional include directories", but I am still getting this error. Can anyone please help me out

Daniel Rossberg (Mar 23 2020 at 15:03):

Is it possible, that you added the include paths for the release, but not the debug configuration?

Mitesh (Mar 23 2020 at 15:10):

the project properties under debug menu are same as the properties in above pictures
I guess its using same properties.

Daniel Rossberg (Mar 23 2020 at 15:16):

I can't see the include paths in above picture.
Do you guess or do you know?

You have to look for the project's debug configuration settings. (Do you know how/where?)

this one right?

Daniel Rossberg (Mar 23 2020 at 15:20):

No. Look at the top of this settings dialog. There you see "Configuration: Release". You need to switch it to debug (or "both").

Mitesh (Mar 23 2020 at 15:23):

got this in output. Also the cmd screen exits within a second.
why does the program returns 2 instead of 0?

Sean (Mar 24 2020 at 06:45):

@Mitesh if you are attempting to do the appleseed tasks, I suggest connecting up with @Jeffrey Liu to see his work and where he left off at. amazing progress. you'd want to start from there if you're wanting to carry that torch.

This is hard to say without knowing the program. I would expect a return 2; (or similar) in the main() function.

yeah it was the bu_exit(), there was some problem with command line arguements that leaded it to exit the code with 2.
