16:24.01brlcadtarzeau: not yet
16:24.39brlcadtarzeau: the info on that url is rather out-dated
16:26.22brlcadthe package name should be BRL-CAD, it's covered by multiple licenses, 7.2.6 is the latest (with 7.4.0 posting in about 10 days), the url should be http://brlcad.org, upstream author probably deserves some discussion

17:48.00tarzeaubrlcad: hi
17:48.10tarzeauis someone packaging it?
17:48.26tarzeaudo you guys need help? i'd like to, since we want to use it at our campus, and i'm their debian hero guy ;)
18:31.06brlcadhelp is always welcome! :)
18:31.52brlcadtarzeau: as far as I know, nobody is actively packaging it so your help is more than welcome
18:32.17brlcaddebian actually gives me more grief than almost all other platforms combined (except solaris, of course..)
18:33.04brlcadso that probably just goes to show that we do need more work on infrastructure support ;)
18:34.27brlcadtarzeau: the biggest hold-up was that BRL-CAD traditionally has preferred a single install root -- this does not bode well with most of the packaging systems that have arisen in the past decade or so (apt, portage, ports)
18:34.39tarzeaugreat!
18:35.05tarzeaubut debian is the most easy one!
18:35.06brlcadso we've put a little effort in to allow for the more integrated install
18:35.11brlcad~dict grief
18:35.27brlcadheh, dict ~= problems
18:35.29tarzeauok it's good to know nobody works on it
18:35.46Twingy_~dict schism
18:35.49tarzeauso, that means, i will. and i will also want to talk with you, you are one of the developers of it?
18:36.09brlcadyes
18:36.11tarzeauyou know there's software called "schism" (an impulse tracker clone)
18:36.26tarzeaubrlcad was used for a presentation i've seen: ronja.twibright.com
18:37.03brlcadyes, the guy that runs ronja's been in here quite a bit
18:37.13brlcadvery impressive use ;)
18:37.27tarzeauyep ;)
18:37.44brlcadhe made those models in about a day after learning brl-cad
18:37.44tarzeaui've just downloaded the tar.gz today at work and i will look at it tomorrow
18:37.54tarzeauheh! i've learnt blender some time ago,
18:38.00tarzeaubut of course it's something different
18:39.15tarzeaui think the "werkstatt" and "physics students" will profit from this software alot, when they have it ready to clickstart
18:39.39tarzeaulooks like tcl/tk
18:40.20tarzeauthere's no native (cocoa) port to os x, is there?
18:41.04brlcadthere is not yet
18:41.20brlcadmged is a tcl/tk and C mix
18:41.48tarzeauis there one planned?
18:41.56tarzeaubecause if there is, you know about GNUstep ? ;)
18:42.00brlcadthere is Aqua Tk that will give the proper look/feel, but when I last tried linking against that framework, it was woefully buggy
18:42.25brlcadthat was, though, more than a year ago .. so it's definitely time to try AquaTk again
18:42.44brlcadwith that, the "port" will be a simple recompile
18:42.58brlcadvery aware of gnustep :)
18:43.08tarzeaugood ;)
18:44.40CIA-3BRL-CAD: 03brlcad * 10brlcad/doc/html/ (13 files in 13 dirs): revert the new path changes and install the html docs into the datadir root until mged is fixed to find them in doc/
18:58.02brlcadtarzeau: if I may ask, which school are you at?
18:58.25tarzeau{www,nic}.phys.ethz.ch
18:59.02brlcadthat's a long name .. :)
19:02.44tarzeauwell ETH in Zürich
19:02.49tarzeauthat's the webpages
19:03.01tarzeauwhere are you at?
19:03.28brlcadMaryland, US
19:03.58brlcadETH is much shorter .. though I meant the full expansion :)
19:26.25tarzeauin german: eidgenössiche technische hochschule zürich
19:26.43tarzeauin english: swiss federal institute of technologz zurich
19:26.49tarzeauthink of it as mit.edu, just twice as big
19:27.23tarzeauhttp://www.seismo.ethz.ch/div/find_sed.html i'm in the 6 edged building

20:52.03CIA-3BRL-CAD: AM_MAINTAINER_MODE for now. would also like no-dependencies but have not
20:52.03CIA-3BRL-CAD: figured out how to dynamically set that option without causing vast troubles.
20:52.03CIA-3BRL-CAD: (including AM_INIT_AUTOMAKE multiple times is apparently buggy for at least
20:52.04CIA-3BRL-CAD: several versions of automake resulting in incorrect expansions in the resultant

22:00.10brlcadcolors and plaids.. plaid's not a color? :)
22:00.22menotumeno, it's a pattern of colors
22:00.34menotumeIMHO
22:01.39brlcad:)
22:02.05menotumethe conference is a bit more advanced than just 'solids' :p
22:02.12brlcadhehe
22:02.27brlcadwho would have thought that someone would have a conference on color :)
22:02.41menotumeor 'shapes and solids' ?
22:02.50menotumelol
22:03.17brlcadwho hosts it?
22:03.17archivist_especially if male
22:03.22brlcadacm/ieee?

22:03.47brlcadseminar on triangles?
22:03.49brlcadwhich one? :)
22:03.54brlcadthere were lots
22:04.01menotumehehe
22:04.25menotumeI heard the icoceles (sp) was truely angular

23:27.56brlcadyay, 64-bit amd linux build doesn't require manual path tweaking any more
23:28.06brlcadclean build

23:35.39CIA-3BRL-CAD: 03brlcad * 10brlcad/TODO: fix mged backgrounding when parent quickly fails (e.g. no DISPLAY)
23:36.22menotumeyay. i was wondering when you were gonna fix that
23:37.10menotumei've never gotten a clean build on brlcad
23:37.21brlcadreally?
23:37.26menotumereally
23:37.27brlcadwhich system?
23:37.33CIA-3BRL-CAD: 03brlcad * 10brlcad/TODO: make X11 optional at configure-time
23:37.42menotumei've never tried to build it :)
23:37.47brlcadbah :)

23:38.55brlcadbrl-cad's cross-platform support dwarfs bz (even though bz is much better than most), yet there are always still "issues" with some of them
23:39.33brlcadpart of it is because we picked up an entirely new build system "recently" after about 15 years with another
23:39.35menotumeyes, i would image
23:39.38menotumeimagine
23:39.45menotumewow
23:40.01menotumeis this more of a true 'CAD', or a scene renderere ?
23:40.16brlcadmore of a true cad
23:40.20brlcadit's a solid modeling system
23:40.22menotumegotya
23:41.02brlcadimage processing tools, rendering and some engineering analysis tools, a gui-based solid modeler
23:41.26menotumeahhh, the hubble render looks good
23:41.28brlcadgeometry converters, procedural data generators
23:41.42brlcadmeh, it's okay
23:42.23brlcadthe render was never designed for realistic pictures, designed for numerical accuracy, stability, repeatability, etc
23:42.25menotumewhat kind of time did it take to render that final scene ?
23:42.33menotumegotya
23:42.48brlcadtwo new renders were just recently added though, that give the realism
23:42.51menotumejust approx. minutes or hours ?
23:43.26brlcadwhich one?
23:43.32menotumehubble
23:43.38brlcadseconds
23:43.45menotumeahhh :)
23:43.55brlcadthe raytracer is pretty darn fast :)
23:43.56menotumekewl
23:44.10brlcadthough an even faster one was recently added too as part of adrt
23:44.23menotumei take it you can set up light(s)
23:44.49brlcadof course
23:44.53menotume:)
23:45.07brlcadhere's one that was done with the adrt path tracer that you might have seen on #bz a while back
23:45.11brlcadhttp://bzflag.bz/tmp/humvee.png
23:45.11menotumeok, /me adds this to the near-top of the to-dolist: play with brlcad
23:45.32brlcadhey, don't play with me :)
23:45.37brlcadplay with brl-cad ;)
23:45.43menotumehehe
23:45.47menotumethat looks good
23:46.01menotumehmmm, no transparent objects ?
23:46.35menotumenice diffuse lighting there
23:46.40brlcadno, it can .. just was more simple to paint em gray
23:46.48menotume:)
23:47.01brlcadhttp://brlcad.org/images/mged.jpg
23:47.07menotumeya, or you'd have to do some interior work
23:48.01menotumeokies
23:48.08menotumesome of that is right over my head
23:48.20menotumecaustics percent, photons, etc.
23:48.36menotume16 processors ?
23:48.37brlcadintentionally a bit "busy"
23:48.50brlcadit will scale to as many as you can thow at it
23:49.14menotumeahh haa. here, i can throw one at it :)
23:49.22brlcadhehe
23:49.51menotumenice - i must play woith it
23:50.00brlcadbrl-cad's rt was actually the first parallel ray-tracer
23:50.14menotumeah haa
23:50.17brlcad20 years ago or so
23:50.23menotumeeeeesh
23:50.34menotumewhen you wwere 13, i take it ?
23:50.55brlcadso it's been designed to scale up from a single cpu to the biggest supercomputers (which it's run on regularly)
23:51.41menotumehttp://www.sicompos.com/oldsite/pcpos/index.html
23:51.45brlcadbrl-cad's been under development since 1979 ..  :)
23:51.54menotumethat's about all i've done - with Corel Dream-3d years ago
23:51.58brlcadfirst released in '84 iirc
23:52.11menotumebut, it was very detailed, connector panel, every little screw, etc.
23:52.32menotumehttp://www.sicompos.com/oldsite/pcpos/pics/fc01b.html
23:52.36menotumethat's a better one
23:52.37menotume:)
23:52.54menotumeI used to work there :)
23:53.16brlcadyou could make a brl-cad model out of that quickly enough ;)
23:53.27menotumeyeah
23:53.27brlcadand then perform ballistic analysis on it ;)
23:53.32menotume:)
23:53.33TwingyI'd have more fun making the actual unit
23:53.42menotumewell, i did that
23:54.05menotumethat is, i did the system s/w for it
23:54.28Twingytell me you didn't hand code assembly :)
23:54.33menotumewish i had some of the old stuff i did still
23:54.46menotumemade movies of the keyboards - how to replace an overlay
23:54.57brlcadblowtorch?
23:55.44menotumehehe, no the lid hinging up, overlays came out, etc.
23:56.01menotumewow, 1997
23:56.14menotumeeeesh, i am getting sooo old :)
23:56.43brlcadnever too late to take up cad development ;)
23:56.53menotumeheh
23:57.05brlcaduncle sam wants you!
23:57.25brlcador would his niece samantha be more enticing? :)
23:57.30menotumehow much does uncle pay ? :)
23:57.40menotumeahhh, fringe bennies
23:57.58Twingyhrm
23:57.58Twingymy UPS just kicked in
