| 13:38.41 | AchiestDragon | hi |
| 14:21.44 | learner | hello |
| 14:22.14 | AchiestDragon | ha life :) |
| 14:40.53 | learner | :) |
| 14:43.32 | AchiestDragon | grrr , been generating a gui to show an idea , done it twice now , but qt designer crashed on me both times , another 2 hrs down the drain |
| 14:44.41 | learner | ahh, yes .. gotta save often with that sucker |
| 14:46.14 | AchiestDragon | had almost finished it as well |
| 14:46.48 | learner | i'm sure it was wonderful ;) |
| 14:50.38 | AchiestDragon | trying to show an idea for an ( auto parts generator ) , so objects such as box, tube , I beems etc can be easaly generated |
| 14:52.36 | AchiestDragon | by selecting from the standard end profiles ( or a custom profile ) specifying the lenth or a bend profile file and it should generate the main part , then you may have to do object add/ subtract to put holes in it |
| 14:53.16 | learner | sort of like basic feature-based editing |
| 14:53.29 | AchiestDragon | yes |
| 14:57.24 | AchiestDragon | so for a paperclip it would be round bar 1mm dia folowing say a dxf of a paperclip bend path |
| 15:01.34 | AchiestDragon | component libs would be usefull so you could have std nuts bolts screws or whatever |
| 15:05.21 | brlcad | yeah, that would be useful |
| 15:07.05 | AchiestDragon | question that i find odd it that brlcad was a us gov program , so why are dimementions in mm |
| 15:07.43 | brlcad | :) |
| 15:08.08 | brlcad | actually, you can set to units to whatever you like, it's just the default that's mm ;) |
| 15:08.20 | AchiestDragon | k |
| 15:08.22 | AchiestDragon | :) |
| 15:08.26 | brlcad | units command |
| 15:09.21 | AchiestDragon | is fine for me in mm , just seemed odd that it was by default |
| 15:10.27 | brlcad | brl-cad's always had an international community of users, 'some' default unit of measurement was needed |
| 15:11.16 | brlcad | just because most of the rest of the country has difficulty adopting metric doesn't mean we can't :) |
| 15:11.47 | *** join/#brlcad docelic (n=docelic@195.246.23.200) | |
| 15:13.19 | AchiestDragon | ive been using metric and imperial units for some time , since the uk went metric in the 70's , its still a case of some odd things like 1"*1" steel bar comes in 6m lenths now |
| 15:15.51 | AchiestDragon | finding imperial spanners and tools like drill bits , all seem to be metric here now so its hard to get imperial tools |
| 15:16.00 | brlcad | yeah, that's what makes the unit command useful.. you can change units on the fly for each object if you wanted |
| 15:17.49 | AchiestDragon | at least you dont need 12 fingers when calculating metric mesurement |
| 15:17.57 | AchiestDragon | s |
| 15:20.13 | AchiestDragon | cool, so i can have a 1" cube with a 20mm hole though it for example , |

| 15:24.44 | AchiestDragon | what's the time scaile for archer for linux ( well even for a working alpha version ) |
| 15:29.03 | brlcad | hopefully by the end of this month |
| 15:29.25 | AchiestDragon | :) |
| 15:33.19 | AchiestDragon | will need to sort cvs out so i can test it |
| 15:36.31 | learner | that would be cool |
| 15:38.59 | AchiestDragon | now cvs is working ok this time , not changed anything so must of been sourcefourge's end |
| 15:39.20 | brlcad | usually is |
| 15:39.39 | brlcad | usually just a matter of waiting for sf.net guys to get in to work the next day.. |
| 15:47.50 | AchiestDragon | any ./configure options you recomend other than --enable-optimized debug ones for example |
| 15:53.01 | *** join/#brlcad Twingy (n=justin@pcp0011647505pcs.aberdn01.md.comcast.net) | |
| 16:09.47 | brlcad | AchiestDragon: debug is default, regardless of optimization --enable-optimized is all I'd suggest |
| 16:10.07 | brlcad | the rest is all auto-detect and will build everything it can |
| 16:10.28 | AchiestDragon | k , is on make at moment , did ./configure --enable-optimized --prefix=$HOME |
| 16:16.25 | brlcad | that'll work, though it's going to toss a bunch of dirs into $HOME |
| 16:16.40 | brlcad | bin, share, lib, include, man |
| 16:18.21 | AchiestDragon | should of done $HOME/brlcad but bit late now |
| 16:19.26 | AchiestDragon | well guess not , have'nt done make install yet |
| 16:19.53 | brlcad | it does matter ;) |
| 16:20.12 | brlcad | the libraries and resource utilities keep track of where they will install at configure time |
| 16:20.56 | AchiestDragon | stoped it and started with ./configure --enable-optimized --prefix=$HOME/brlcad this time |
| 17:00.59 | AchiestDragon | :) well cvs version compiles ok and seems to be running ok |
| 17:01.58 | AchiestDragon | see that wire frame overlay seems to be working in perspective mode now |
| 17:10.31 | brlcad | shouldn't have ever stopped working .. |
| 17:11.09 | brlcad | except for shaded_mode where there's a bug |
| 17:12.26 | AchiestDragon | ha , well when i have overlay selected and whenever i enabled perspective the wire frame vanished , making it hard to position the image , had to do a quick render and guess when repositioning the image |
| 17:14.09 | AchiestDragon | since doing this render its now not showing , hopes it comes back , half way though a trace so will wait for it to finish first |
| 17:17.05 | brlcad | you do know about underlay/overlay, yes? |
| 17:17.32 | brlcad | if you're rendering to the framebuffer in the graphics window, the wireframe can be on top or below the framebuffer |
| 17:19.03 | AchiestDragon | yes underlay draws it underneath and overlay draws it over the top , so overlay should desplay it regardles |
| 17:20.25 | AchiestDragon | but depends on what bit is beeing layed over the top layer will be the prominent image , |
| 17:21.18 | AchiestDragon | its set to underlay , theres no wire frame , so i guess thats a bug ?? |
| 17:23.54 | AchiestDragon | i think from what i know of it that the underlay refers to the rendered image , not the wire frame , so the frame is top with the renderd image under it , that right ? |
| 17:24.26 | AchiestDragon | it seems to work that way when its working ok |
| 17:25.09 | brlcad | yes |
| 17:26.03 | AchiestDragon | will see if i can get it back when its finished this ,, its 50% though a photonmap render |
| 17:26.34 | brlcad | if you turn perspective off, does it return? |
| 17:27.03 | brlcad | the size projection of perspective often places the wireframe in front of the clipping plane |
| 17:27.52 | brlcad | you have z-clipping on or off? |
| 17:28.32 | brlcad | (make sure it's off -- Misc menu) |
| 17:30.23 | AchiestDragon | k will try when its done this render ,,btw z clipping is on |
| 17:30.32 | AchiestDragon | hopes its that |
| 17:30.58 | brlcad | once the render starts, it will render the state from image start |
| 17:31.44 | brlcad | it doesn't matter what you change after that in the view |
| 17:32.04 | brlcad | so you can turn perspective on/off or even spin the model around, it won't affect the image being rendered |
| 17:32.14 | AchiestDragon | k |
| 17:32.47 | brlcad | the only thing you can't change is the window dimensions, since it will distort the framebuffer |
| 17:33.06 | AchiestDragon | k :) z clipping on / off , brings the wire frame back |
| 17:36.33 | brlcad | yeah, so it's a matter of how large the thing is that you're rendering |
| 17:37.17 | AchiestDragon | k ,, m35.g |
| 17:50.33 | AchiestDragon | odd its finished the raytrace but the image is the same , ie still showing the quick render |
| 17:58.14 | AchiestDragon | maybe me |
| 18:03.15 | *** join/#brlcad DTRemenak (n=DTRemena@DHCP-170-143.caltech.edu) | |
| 18:21.23 | brlcad | AchiestDragon: you said you were doing a photonmap render of the m35? that would require a _lot_ of photons without putting the m35 into a box |
| 20:20.59 | AchiestDragon | yes ,, but it should still show the image it has just rendered shouldent it ??? |
| 20:23.25 | AchiestDragon | i did a render using surface normals first this time , so i get a image that is coloured diferently , then did a photonmap render , it has finished some time ago but the image beeing displayed is still the coloured surface normals one |
| 20:24.24 | AchiestDragon | is this a bug or is there a diferent output option to turn on ?? |
| 20:29.05 | AchiestDragon | see http://www.whipy.demon.co.uk/snapshot3.png |
| 21:06.11 | AchiestDragon | ok closed the program reopened it , set the photons to 4194304 and started , this is going to take a long time , hope it works |
| 21:39.42 | brlcad | heh... |
| 21:40.12 | brlcad | unless you have a massive cluster, I doubt that many photons will complete this month without putting the truck in a box ;) |
| 21:41.02 | brlcad | hmm, that screenshot helps -- it did not terminate correctly |
| 21:42.10 | brlcad | looks like a bug in the photon map rendering code.. I'd file a report on it, if you dont' mind |
| 21:53.13 | AchiestDragon | k |
| 21:54.18 | AchiestDragon | no big cluster here, a its dual xeon 2Ghz machine |
| 22:02.39 | AchiestDragon | and it only seems to be using 25% of cpu |
| 22:04.11 | brlcad | probabbly swapping .. that many photons require a fair bit of memory |
| 22:04.22 | brlcad | unless it's a dual-core dual |
| 22:04.49 | brlcad | or hyperthreaded which I gather it is if it's xeons |
| 22:05.09 | brlcad | the prep stage in photon mapping hasn't been parallelized |
| 22:05.18 | AchiestDragon | k |
| 22:05.21 | brlcad | so it's just using one cpu (one virtual of your four) |

| 22:10.00 | AchiestDragon | bug report submitted |
| 22:43.48 | AchiestDragon | opps it submitted it twice |
| 22:45.14 | brlcad | no problem, it'll get cleaned up |
| 22:47.58 | pra5ad | hey sean |
| 22:48.02 | pra5ad | where's ur singleton code |
| 22:52.18 | brlcad | pra5ad: http://ftp.brlcad.org/tmp/Singleton.h or http://ftp.brlcad.org/tmp/Singleton2.h |
| 22:52.58 | brlcad | 2 is more simple, and what I use in bz -- presumes single thread model and only default constructor creation |
| 22:53.17 | ``Erik | grumble grumble hxx grumbl |
| 22:53.18 | brlcad | the first has (mostly unimplemented) hooks for threading and memory methods |
| 22:54.55 | brlcad | pra5ad: so to use it.. say i have a singleton file manager, you derive off the templatized version: |
| 22:54.58 | brlcad | class FileManager : public Singleton<FileManager> |
| 22:55.31 | brlcad | and make him a friend with himself in his protected or private: |
| 22:55.33 | brlcad | friend class Singleton<FileManager>; |
| 22:55.43 | brlcad | where you've also placed the constructor/destructor |
| 22:57.04 | brlcad | initialize your singleton in a compilation unit so that you have a handle: |
| 22:57.13 | brlcad | template <> |
| 22:57.15 | brlcad | FileManager* Singleton<FileManager>::_instance = (FileManager*)0; |
| 22:57.25 | brlcad | and that does it |
| 22:57.41 | brlcad | might want to create a #define to make accessing the instance simple: |
| 22:57.51 | brlcad | #define FILEMGR (FileManager::instance()) |
| 22:58.21 | brlcad | so then I can use FILEMGR.lookUpFile("blah.h"); etc |
