03:48.21CIA-21BRL-CAD: 03pacman87 * r31244 10/brlcad/trunk/src/librt/g_hyp.c: Enhanced plot() with more precise wireframe, and changed from hardcoded statements to a loop
03:49.41pacman87new and improved: https://webspace.utexas.edu/trv82/www/hyp3.png
04:47.30brlcadawesome!
04:48.00brlcadthat's pretty cool, so does it raytrace?

04:56.18pacman87brlcad: no, rt fails.  i haven't really looked into it that closely
04:56.34pacman87i need to get import5 and export5 working first
04:59.52CIA-21BRL-CAD: 03brlcad * r31245 10/brlcad/trunk/src/mged/adc.c: reorder to avoid forward decl of adc_print_vars, replace M_SQRT2_DIV2 with M_SQRT1_2
05:00.41CIA-21BRL-CAD: 03brlcad * r31246 10/brlcad/trunk/src/mged/chgview.c: don't need defines, vmath.h provides
05:00.53brlcadnods
05:01.29pacman87is there a way to convert a brlcad database to human readable format?
05:01.35pacman87so i can check my exports?
05:01.46pacman87and my imports seperately
05:02.31CIA-21BRL-CAD: 03brlcad * r31247 10/brlcad/trunk/doc/deprecation.txt: deprecate M_SQRT2_DIV2 .. it's entirely unnecessary since it's the same as sqrt(1/2) and/or 1/sqrt(2) .. so M_SQRT1_2 is suitable.
05:05.15CIA-21BRL-CAD: 03brlcad * r31248 10/brlcad/trunk/include/vmath.h: beef up the tolerances on the standard M_ math defines, add a couple that were missing, and protect them all individually for the OS's that define some but not others.
05:06.06brlcadpacman87: only after you implement the hook function for it
05:07.03pacman87hmmm?
05:11.06pacman87is the database file format documented somewhere
05:11.14brlcadusual means for testing an individual primitive is to implement the rt_*_print() and rt_*_describe() callbacks
05:11.29brlcaddescribe is what you see when you run "l object"
05:11.46pacman87ok
05:11.59brlcadprint is what you see during edit when faceplace is enabled (it's on the gui menu, Misc)
05:12.58pacman87i'm still running classic mode, though, so no menus for me
05:15.32brlcadyeah, you get faceplate by default
05:15.40brlcadthat's the gui overlay you're looking at
05:17.16*** join/#brlcad vedge (n=vedge@205-237-251-204.ilesdelamadeleine.ca)
05:18.15brlcadif you run oed (i.e. oed / primitive) or sed (i.e. sed primitive) on a given primitive .. it'll enter edit mode and display the print() arguments on the overlay
05:18.53brlcadgenerally speaking, though, l ("ell") is more flexible since you can print literally anything and faster to test with (no edit mode)
05:19.03pacman87mged> oed / hyp.s
05:19.03pacman87mged> rt_nul_xform unimplemented
05:19.03pacman87transform_editing_solid failed to apply a matrix transform, aborting
05:19.31brlcadah, yeah
05:19.39brlcadso stick to l then :)
05:19.42pacman87that, and "mged> l hyp.s" actually works now :)
05:19.57brlcadyou can't go into edit mode without a couple of the other callbacks
05:20.14pacman87thanks, bedtime for me now.  i'll pick this up later
05:20.19brlcadnods
05:20.24brlcadnice progress!
05:20.30pacman87thanks
05:20.39pacman87do i need to worry about tolerances for the wireframe?
05:20.46brlcadmind if I share those screenshots?
05:20.52pacman87not at all :)
05:20.54pacman87with whom?
05:21.17brlcadnah, the wireframe just needs to be "good enough"
05:21.33pacman87so just tess() needs the tolerance?
05:21.34brlcadat least not until there's proper high/low support
05:21.42brlcadtess definitely needs it, yet
05:21.46brlcads/yet/yes/
05:21.59pacman87my question was more in the 'just' than in the 'tess()'
05:22.18brlcadcontemplates
05:22.25pacman87ie, is tolerance used for anything else?
05:23.04brlcadyeah
05:23.26brlcadi mean, whenever you perform a computation in any of the routines, there are a set of tolerances to take into consideration
05:23.34brlcade.g. a base computation tolerance
05:23.41brlcada distance tolerance
05:24.09brlcadyou don't "have" to use them strictly speaking, but you'll just likely get bad behavior if they're not implemented
05:25.02pacman87ok
05:25.03brlcadthe extent at which various primitives properly use and need tolerancing certainly varies, so just have to use good judgement
05:25.47brlcadfor example, in the arbs, it uses the distance tolerance to determine whether or not two points are the same point or not
05:26.08brlcadif those  points coincide, then it's not an arb8 .. it's an arb7 or arb6, etc
05:26.23pacman87makes sense
05:27.49pacman87tries to go to bed again, goodnight for real this time

20:44.55madantdid the template thing work out for the wiki ?
20:45.11pacman87i didnt' get it working yet, any ideas?
20:45.48madantwhat exactly is the error ? the plugin not supported due to version ?

20:49.07madantwhere did u receive the template from ?
20:49.11madantwikimedia ?
20:49.15pacman87wikipedia
20:50.12pacman87http://en.wikipedia.org/wiki/Template:Infobox
20:51.47madanthmm.. they say it is metatemplate used to make other templates..
20:52.05madantso we would have to use another template or write one to use it ?
20:52.17pacman87their examples show it in use
20:58.23madanthmm..
20:58.52madanti better go eat something :) 02:20 am here :)

23:36.11brlcadarrives in NY
23:37.16brlcadandrecastelo: yeah, something like that
23:38.44brlcadGnontghol: there isn't a debian maintainer (that I'm aware of) if you're interested
23:46.25Gnontgholbrlcad: I am new to this packing thing. I don't think I am the man.
23:46.38brlcadfair enough
23:46.47brlcadthough you can certainly try to be the man ;)
23:47.29brlcadthe .deb needs a lot of work
23:47.45brlcadregardless of maintainership
23:48.36andrecastelobrlcad: ok, i'll commit.. if anything goes wrong you can feel free to break my legs :)
23:50.14pacman87andrecastelo: do you have a dev log up somewhere?
23:50.41andrecastelopacman87: dev log?? hm don't think so
23:51.44GnontgholI think the age of this project is making the life of the .deb maintainer hard.
23:51.55pacman87the other three of us have our logs linked from http://brlcad.org/wiki/Google_Summer_of_Code/2008
23:52.04Gnontgholimplicit declarations and name colitions all around the place
23:52.58louipcGnontghol: well the default install location is safe
23:54.03andrecastelopacman87: ahh.. i had a blog set up for gsoc, will link there
23:54.14louipcGnontghol: /usr/brlcad/ I stick it in /opt/brlcad/ because I don't think /usr is really supposed to be populated with per-package directories
23:54.58pacman87andrecastelo: cool, thanks.  i like to see what other coders are workign on :)
23:56.33Gnontghollouipc: You are right, but making a spessial install location is a bit hackish
23:58.40GnontgholI sugest that you do a total code and structure review and release the reviewed code as brlcad-8.0
