| 00:35.22 | brlcad | you should be able to pull a cvs checkout of -r rel-7-8-4 |

| 00:37.44 | tedcx | brlcad: where is an x64 source for linux? |
| 00:38.15 | brlcad | the source is the same for all platforms |

| 02:20.10 | deltazap | man, being able to use tcl in mged is pretty awesome |
| 02:20.23 | deltazap | now if it could do ruby, we'd be onto something ;) |
| 02:22.20 | brlcad | deltazap: soon enough :) |
| 02:22.53 | deltazap | :D |
| 02:29.09 | deltazap | brlcad: is there a guide around on how to set up distributed ray tracing? |
| 02:30.13 | brlcad | deltazap: not a really good one .. the closest is probably the remrt manual page |
| 02:31.18 | brlcad | basic idea is to set up remrt with all of the usual rt parameters that you might want to use |
| 02:31.25 | brlcad | then run rtsrv on all your distributed hosts |
| 02:36.59 | deltazap | alright, i'll have to start reading up |
| 02:39.56 | deltazap | my ibook doesn't have quite enough power to do photon mapping by itself :P |
| 03:05.55 | deltazap | i know i asked this a few nights ago, but i don't know if someone responed |
| 03:06.25 | deltazap | is there a way to replace one primative for another region, for instance? |
| 03:24.38 | IriX64 | Twingy: gave it some light www.irix64.spaces.live.com/photos |
| 03:25.10 | Twingy | you are stilling missing an environment IriX64 |
| 03:29.27 | IriX64 | man its in flight :P |
| 03:29.49 | deltazap | whoops, crashed mged |
| 03:46.36 | IriX64 | thought you crashed havoc for a moment :) |
| 04:01.53 | IriX64 | want to see my bbs again.... i'm darn well going to. |
| 04:02.30 | IriX64 | say is random chatter and mutterings permitted or not permitted during work hours? |
| 04:16.16 | brlcad | deltazap: combinations use named references, so if you refer to a primitive and want to replace that primitive with something else, (whether it be a region or another primivite) you can use the mvall command |
| 04:17.07 | deltazap | ah, nice :) |
| 04:17.37 | brlcad | so to replace a primitive p.s with a region c.r, you'd mvall p.s c.r then restore p.s with mv c.r p.s then kill c.r (which is a primitive) and then create whatever you want to replace it with |
| 04:18.33 | deltazap | alright |
| 04:18.45 | brlcad | not the clearest of examples, but hopefully you see -- you renamed all references to the new name, then put something new in place |
| 04:22.28 | brlcad | these are in the 'Creating Geometry' section on http://ftp.brlcad.org/MGED_Quick_Reference_Card.pdf if that thelps |
| 04:22.28 | deltazap | next odd question: is there any way to resize a region? |
| 04:22.28 | deltazap | i have that printed out here somewhere |
| 04:22.29 | brlcad | resizing is another way of saying scale |
| 04:22.29 | brlcad | found in the "S R G set glob_compat_mode 1 |
| 04:22.29 | brlcad | eek |
| 04:22.29 | brlcad | Scaling and Resizing Geometry in non-unicode form :) |
| 04:22.29 | deltazap | ok |
| 04:22.34 | brlcad | basically, you oed the object (or matrix select via gui -- same thing) -- then sca or select Scale on the menu |
| 04:22.57 | deltazap | that's what i thought, but in the matrix selection, the region wasn't listed |
| 04:23.33 | brlcad | if you want to apply the scale to the primitives themselves, you'd use the push and/or xpush commands |
| 04:24.28 | deltazap | ok |
| 04:29.27 | deltazap | last random question of the night: how well does that .g -> cubit converter and do you need testers :P |
| 04:29.36 | deltazap | *work |
| 04:33.16 | brlcad | it actually works surprisingly well .. what I'm trying to sort out, though, is how we can go about distribution |
| 05:02.45 | IriX64 | infozip rather :) |
| 05:03.26 | IriX64 | tedcx did you get yours to compile (to get back on topic) |
| 05:05.42 | IriX64 | brlcad: can i really use this cvs client to access BRL-CAD latest code? |
| 05:07.42 | brlcad | the very latest is always in cvs |
| 05:07.55 | IriX64 | whats the learning curve like? |
| 05:08.05 | brlcad | it's not incredibly different |
| 05:08.14 | brlcad | but it's current active development |
| 05:08.28 | brlcad | so even the slightest typo and something might not build |
| 05:09.02 | IriX64 | i see you use cvs till you get something building error free then you release a new source tarball? |
| 05:09.20 | brlcad | it's generally expected that you have a basic understanding of how to resolve the simple build errors and occasional build failures or run-time glitches if you work off of cvs HEAD |
| 05:09.38 | IriX64 | ill wait for the source distribution, thanks |
| 05:10.09 | IriX64 | i mean i think i can reslove build issues, but i have a slow link |
| 05:10.13 | brlcad | sort of .. the process has changed over the years and generally speaking, head is stable and we simply release when we want |
| 05:10.34 | brlcad | which is "supposed" to be once a month if everything is running smooth |
| 05:10.57 | IriX64 | supposed mean a lot of things to a lot of people :) |
| 05:11.03 | IriX64 | +s |
| 05:12.05 | IriX64 | but on the other hand i downloaded the thing, maybe ill play with it whats the address or is it on sourceforge? |
| 05:13.27 | brlcad | it's all on sourceforge, including detailed instructions |
| 05:13.41 | brlcad | just follow the CVS link on the sf project page |
| 05:16.12 | IriX64 | ty |
| 05:22.49 | CIA-21 | BRL-CAD: 03brlcad * 10brlcad/doc/html/bookmarks.html: add an initial bookmarks file in NETSCAPE-Bookmark-file-1 html doctype format. slews of links missing, but stub initial sections for news, distribution, documentation, source analysis, and external linkages. |

| 05:28.56 | brlcad | if you had a cvs checkout -- those commits are actually "live" -- you could do a cvs update on your source tree and get the modification immediately no matter what it is |
| 05:30.25 | IriX64 | I see, i'm skimming documentation here but see no way to connect to sourceforge, or at least i haven't found it yet. |

| 15:40.26 | deltazap | hmm, trying to figure out why my photon mapping looks blown out in the render i did over night |
| 16:08.56 | brlcad | light might be too bright |
| 16:09.25 | brlcad | have to be cautious towards the number of photons being used and the lumens of the light in the scene |
| 16:15.54 | clock_ | brlcad: if I want caustics, do I have to use photon mapping? |
| 16:17.05 | brlcad | clock_: yes |
| 16:17.14 | brlcad | or some other global illumination render |
| 16:17.57 | clock_ | brlcad: and in BRL-CAD that means always photon mapping? |
| 16:18.59 | clock_ | brlcad: how can I render with photon mapping? With rt? Or other command? |
| 16:19.07 | clock_ | I didn't find photon mapping in rt --help |
| 16:19.57 | brlcad | clock_: no, it means photon mapping or converting the model to adrt and rendering it with rise |
| 16:20.18 | brlcad | clock_: it's easier to select photon mapping from the raytrace control panel in the gui |
| 16:20.19 | clock_ | is rise part of BRL-CAD? |
| 16:20.21 | brlcad | there are a lot of options |
| 16:20.32 | clock_ | brlcad: I want for automated processing |
| 16:20.37 | brlcad | RISE is a part of ADRT, which is included with BRL-CAD (but not compiled by default yet) |
| 16:21.04 | clock_ | man -a rt rt - AIMS Lab Radiotrack FM radio device |
| 16:21.13 | brlcad | clock_: I mean use the gui to test/set the options .. then you can review what the command-line parameters are for automation afterwards |
| 16:21.47 | brlcad | the command line params are displayed to the mged console |

| 19:06.02 | ``Erik | um, I'm going to guess that the speedup is inversely proportional to the number of pixels being drawn? O.o cuz, um, that is kinda... y'know, expected :) |

| 19:13.02 | IriX64 | spawnv |
| 19:13.13 | IriX64 | much like exec |
