| 00:04.20 | IriX64 | wish you could see my screen, I attached to X and it came up and havoc is there, but ogl still gives me a segmentation fault when i attach to it, sigh. |
| 00:06.02 | IriX64 | hah it rt'ed |
| 00:06.38 | IriX64 | where does it go? nothing on the graphics screen. |
| 00:19.54 | IriX64 | ill get back to you. |
| 00:23.46 | ``Erik | heh, I tend to ignore ogl and use Xl ... |
| 00:24.02 | IriX64 | man it....should work |
| 00:24.25 | ``Erik | on modern equipment, X stomps the living crap out of ogl for raytrace results... |
| 00:24.45 | IriX64 | based on what hardware? |
| 00:25.22 | IriX64 | my geForce runs at 1g |
| 00:26.10 | IriX64 | well 1.2 but the screen can't keep up (flickers) |
| 00:30.49 | IriX64 | what did you guys change? |
| 00:30.59 | IriX64 | in 7.6.2 it comes up fine. |
| 00:38.38 | deltazap | IriX64: is that apache one of the 'hush hush' files or an example file? |
| 00:40.32 | IriX64 | huh? just something i was compiling |
| 00:40.42 | deltazap | ah |
| 00:41.05 | IriX64 | whats a hush hush file? |
| 00:42.07 | deltazap | well, i hadn't seen that before |
| 00:42.17 | IriX64 | ah |
| 00:42.25 | deltazap | but then again, i still have difficulty looking at the included examples :P |
| 00:43.00 | IriX64 | as they told me, the usual method is to do a tops to examine the database, then do an e "something" |
| 00:48.28 | deltazap | oh great, i need to middle click in this tutorial :( |
| 00:48.37 | deltazap | i've only have one button |
| 00:49.07 | deltazap | :P |
| 00:50.50 | IriX64 | cut it in two :) |
| 00:51.03 | IriX64 | err 3 |
| 00:51.40 | deltazap | :P |
| 00:51.40 | IriX64 | which tutorial are you at? |
| 00:51.49 | deltazap | lesson 6 |
| 00:51.54 | deltazap | i just started the other night |
| 00:52.48 | deltazap | oh, volume 2 |
| 00:52.56 | IriX64 | what does that one show you how to produce (im way behind) |
| 00:53.01 | deltazap | the goblet |
| 00:53.30 | IriX64 | be sure to specify bill of materials that Gold must be used :P |
| 00:53.50 | deltazap | haha |
| 00:55.04 | deltazap | after working with mged for a while, i realized tab completion would be nice :) |
| 00:55.44 | IriX64 | put it in ... be a contributor (unlike me) |
| 00:56.11 | deltazap | i'd have no clue how to implement that |
| 00:56.30 | IriX64 | examine tops20 |
| 00:57.09 | IriX64 | up arrow works tho |
| 00:58.02 | deltazap | if i make an object (primative), how can i change it's properties later |
| 01:08.54 | ``Erik | one button? a ma |
| 01:08.55 | ``Erik | mac? |
| 01:09.38 | ``Erik | every bit of ARL data irix64 has access to is an "open source", nothing "hush hush" |
| 01:10.23 | deltazap | ``Erik: yes |
| 01:11.35 | deltazap | i'm guessing the little bit of problems that i have with some of the compositing of the framebuffer with the wireframe is because of apple's x11 as well |
| 01:12.35 | ``Erik | the ctl/option/apple keys modify clicks so you can get 3 button activity with a 1 button mouse |
| 01:13.22 | ``Erik | oddly enough, mac is probably the MOST supported os... the 4 heaviest developers at the moment all use macs as their destop |
| 01:13.41 | deltazap | i kept trying ctrl-click, but t kept zooming out on me so i thought it wasn't working in x11 |
| 01:13.44 | deltazap | oh, that's funny :) |
| 01:14.02 | ``Erik | apple+click will zoom in option+click will rotate |
| 01:14.05 | ``Erik | iirc |
| 03:21.33 | brlcad | there are no hush hush files floating around anywhere |
| 03:22.05 | brlcad | no geometry, no images. period. |
| 03:22.48 | brlcad | deltazap: tab-completion would be nice .. i.e. usual readline support |
| 03:23.22 | brlcad | you can edit geometry after creating by a couple ways.. there's the Edit->primitive selection option in the menu as well as several ways on the command line |
| 03:23.57 | deltazap | ah, ok |
| 03:24.05 | deltazap | one more question |
| 03:24.17 | deltazap | how can i render an image so i can use it elsewhere |
| 03:31.07 | brlcad | deltazap: on the mged command line, rt -sSIZE -o filename.pix or on the raytrace control panel under "Destination" you can put a filename |
| 03:31.28 | deltazap | ah, i see :) |
| 03:31.53 | brlcad | pix is a raw image format, not useful in most image tools, so you'd then want to run pix-png outside mged (e.g. pix-png myimage.pix > myimage.png) |
| 03:31.54 | deltazap | and i just found the export RT Script |
| 03:32.10 | deltazap | i've messed with pix-png once before |
| 03:32.27 | brlcad | er, pix-png -sSIZE myimage.pix > myimage.png |
| 03:33.08 | brlcad | when/if you set a size, the size has to be used on all the pix* tools, else tool defaults to 512x512 |
| 03:33.32 | deltazap | ah, ok |
| 03:33.46 | brlcad | fyi by default, rt will make pix files read-only so you have to rm -f filename to delete or chmod them |
| 03:46.12 | deltazap | ah, thanks :) |
| 03:46.48 | brlcad | (common newbie issue) ;) |

| 17:20.40 | brlcad | those numbers are looking much better |
| 17:29.05 | Maloeran | What's the hardware? |
| 17:33.22 | IriX64 | amd64 |
| 17:33.30 | IriX64 | model 3800+ |
| 17:33.37 | IriX64 | 1g mem |
| 17:35.29 | Maloeran | My 8 cores Xeon only seems to be 3.5 times faster, though I guess it does not scale too well |
| 17:36.43 | Maloeran | Oh the 3800+ is a X2 of course, dual-core |
| 17:38.23 | Maloeran | Actually, my build is not optimized |
| 17:38.51 | IriX64 | my is but debug is in there |
| 17:40.21 | IriX64 | i did nothing to your data, all is as you gave me. |
| 17:40.35 | brlcad | Maloeran: not the same comparison either |
| 17:41.05 | Maloeran | brlcad, it depends what you mean by "shader". It's presently an user callback |
| 17:41.14 | brlcad | the benchmark images have other characteristics like scene-lights, various shaders, recursion, that all affect the rtfm number |
| 17:41.51 | brlcad | i mean like for actual image generation -- rfdemo level support for making pretty pictures with various settable material properties |
| 17:42.04 | brlcad | not just the libraries capacity to have them, but their existence :) |
| 17:42.24 | Maloeran | Ah, so you mean actually writing the shaders :) |
| 17:42.55 | Maloeran | Yes, I really plan to do that since... about an year. I presently feel I terribly need to take a break from raytracing |
| 17:43.52 | Maloeran | The old demo had dancing lights code that could be imported without too much trouble, although it wouldn't support distributed processing or frame buffering |
| 17:47.13 | Maloeran | Working alone for 8 months on something without cooperation or collaboration is really demotivating, I guess that's why it's called "work"... It's difficult to maintain focus against other projects that involve cooperation and teamwork |
| 17:54.51 | brlcad | Maloeran: yep, to be expected some -- variety is the spice of life! |
| 17:55.30 | brlcad | why do you think I also work on BZFlag? :) |
| 17:55.42 | brlcad | and other open source projects for similar reasons.. |
| 17:55.53 | Maloeran | :) What is BZFlag? I have other projects as well |
| 17:56.14 | brlcad | you've never played bzflag? |
| 17:56.33 | Maloeran | But I think I'm really tired of raytracing at this point, I solved all problems on paper 1-2 years ago and it now has no appeal whatsoever. There are times I think I feel physical pain when I force myself to work on it |
| 17:56.50 | IriX64 | BZFlag=get to work, the boss is on the way? ;) |
| 17:57.06 | brlcad | it's a game .. one of the most popular open source games ever actually, been around for more than a decade, continues to be developed and continues to gain popularity actually unlike a lot of games |
| 17:57.12 | Maloeran | Oh BZFlag, I read about it, I haven't tried |
| 17:57.25 | Maloeran | Very nice project |
| 17:58.11 | IriX64 | reminds me of quake:) |
| 17:58.22 | brlcad | that's where the other half of my time goes |
| 17:58.30 | IriX64 | heh |
| 17:58.39 | brlcad | when the commits aren't flowing in here, it's probably because i'm working on bzflag |
| 17:58.42 | Maloeran | I have asked Survice if I could only work part-time for a little while, put my mind on new problems and stuff I like |
| 17:58.46 | brlcad | or i'm out rowing ;) |
| 17:58.46 | Maloeran | Eheh great |
| 17:59.57 | Maloeran | I'm starting to really like climbing, even in a huge interior gymnasium |
| 18:00.33 | IriX64 | good thing rounds a shape or i would be out of shape :) |
| 18:01.29 | IriX64 | ill be back when the builds finished. |
| 18:02.31 | Maloeran | And my unsafe ( -ffast-math, etc. ) hand-picked optimisation for the BRL-CAD benchmark is now 9 times faster than IriX64's, that's more like it :} |
| 18:03.38 | brlcad | yeah, it would be nice if some more aggressive flags were added during configure |
| 18:04.42 | brlcad | -ffast-math is particularly problematic on some platforms, but there are other useful ones that should be added like the alignment flags |
| 18:05.06 | brlcad | and arch-specific -mcpu style flags |

| 18:20.00 | Maloeran | -mcpu has been deprecated long ago, it's -mtune these days |
| 18:20.57 | brlcad | yep, hence style |
| 18:21.25 | Maloeran | I like how it says I'm 19594 times faster than the reference, it shows the age of BRL-CAD :) |
| 18:23.57 | brlcad | yeah, one of the very first actually reported 1 ;) |
| 18:24.23 | brlcad | running a ray-trace could take days |
| 18:24.38 | dtidrow_work | isn't VGR dead now? |

| 18:25.32 | dtidrow_work | thought it had gotten retired some time ago |
| 18:26.40 | IriX64 | Maloeran: does rt discriminate between colors? |
| 18:27.09 | IriX64 | heh a red thread a green thread ... |
| 18:28.43 | IriX64 | rgb all you need? wait... maybe 256 colors, = 256 threads? |
| 18:35.18 | IriX64 | just spectulating. |
| 18:36.25 | Maloeran | You could theorically shoot different wavelenghts independantely, for even greater realism, but I never heard anyone doing that and BRL-CAD sure doesn't |
| 18:37.02 | Maloeran | independently, rather |
| 18:37.11 | IriX64 | was wondering where it would be usefull |
| 18:38.58 | IriX64 | would be difficult to co-ordinate the rays, unless you had the thread report hit/miss or something |
| 18:39.07 | Maloeran | For photo-realistic rendering of scenes with complex transparent mediums with non-parallel surfaces ( glass prisms ) |
| 18:39.25 | brlcad | brl-cad does shoot ranges of wavelengths in libmultispectral |
| 18:39.32 | IriX64 | heh true color :) |
| 18:39.34 | Maloeran | Oh? Neat |
| 18:40.30 | brlcad | more of the overall everything including the kitchen sink approach |
| 18:40.59 | IriX64 | heh the doitall approach, as opposed to the doitoit :) |
| 18:47.05 | IriX64 | mmm rt glitches every 20 seconds to 50% cpu, you're good. |
