18:10.45AirBenderHello, a friend discovered brlcad yesterday, and looks like a great piece of Software! I got the current svn revision, and tried to compile it on ubuntu 9.10 using gcc 4.4.1, but there's an error regarding a redefinition of getline.
18:12.22AirBenderhave you compiled it  with this GCC version? I know that it's more stricter than previous versions...
18:17.55*** join/#brlcad Elrohir (n=kvirc@p5B14EB90.dip.t-dialin.net)
18:47.38AirBenderexcellent, is compiling now. The problem was related to jove, and apparently it isn't necessary
19:14.18starseekeroh, yeah - I have to disable jove too on gentoo
19:16.49starseekerand it really isn't needed - it's an old editor
19:32.48brlcadhttp://createuniverses.blogspot.com/2009/09/qtcsg-constructive-solid-geometry.html
19:38.06CIA-22BRL-CAD: 03brlcad * r36328 10/brlcad/trunk/src/other/jove/ (jove.h jove_io.c): rename getline/putline to get_line/put_line so as not to conflict with the gnu getline() extension.
19:39.11starseekerbrlcad: that's pretty cool
19:41.04brlcadand the related former project: http://createuniverses.blogspot.com/2008/09/constructive-solid-geometry-program.html
19:41.25brlcadwhich started off of http://unbboolean.sourceforge.net/
19:41.44brlcadno idea if there meshing is any good at all, but interesting nonetheless
19:42.22brlcadespecially whether they provide any sort of topological guarantees like our libnmg
19:42.41brlcador whether they even attempt to address numerical floating point issues
19:42.54starseekerah yes, the hard questions :-)
19:43.14starseekerlikes the lisp scripting they snuck in
20:18.55brlcadthought you would
20:52.21CIA-22BRL-CAD: 03brlcad * r36329 10/brlcad/trunk/src/libged/annotate.c: midstream, but commit progress regardless. stash object(s) into a string while parsing args.
20:52.40CIA-22BRL-CAD: 03brlcad * r36330 10/brlcad/trunk/src/tclscripts/mged/help.tcl: document the y/n option on opendb

21:05.18starseekerbrlcad: heh, thanks brlcad - beat me to it
21:06.51``Eriksvn rm src/other/jove O.o
21:07.07starseekerI think it's scheduled, but we can't do it yet :-(
21:08.12brlcaddeprecated in 7.14, so 7.20 it can die
21:10.23CIA-22BRL-CAD: 03starseeker * r36333 10/brlcad/trunk/src/ (libged/CMakeLists.txt proc-db/Makefile.am): Oops, couple missing items in make files.
21:10.45brlcadstarseeker: np, my bad regardless -- and no problem being called on it to fix bustage, but telling me/you/anyone shouldn't take longer than the fix or we both fail ;)
21:11.07starseekerheh - quite true
21:11.08brlcadlike that one, thx
21:12.08starseekerjust wasn't sure if the coding juices had resulted in a massive whitespace and tweakage fix of jove or not ;-)
21:14.11CIA-22BRL-CAD: 03starseeker * r36334 10/brlcad/trunk/doc/docbook/Makefile.am: Erm, yeah - probably want to bring more than just articles along for the EXTRA_DIST ride...

21:38.48brlcadjove would get no such attention
21:38.53brlcadespecially once deprecated
21:38.56MkopI realize this is off topic, but do any of you know of a CAD package that can handle mirror surfaces and angles of reflection of a laser?
21:39.27brlcadMkop: er, brl-cad does that with basic phong shading
21:39.40Mkopwhat does that mean?
21:39.55brlcadthat other jove fix was just because it was trivial and causing a build failure
21:40.05starseekernods
21:40.44brlcadMkop: we have a ray-tracing engine in brl-cad that is used for shooting rays, which can be and are used to simulate lots of things
21:40.52brlcadsuch as lasers
21:41.02brlcadour optics library handles basic material interactions
21:41.22brlcadcomputing surface normals and reflection rays is pretty trivial
21:41.58brlcadyou'd have to write a driver application or set up some custom scripts, but depends on what exactly you need
21:42.07brlcadotherwies, no, can't help you with other packages ;)
21:42.55MkopI'm designing a laser galvo system
21:43.18Mkopi.e. we have out-of-box galvos, and want to create drawings showing what will happen to the beam when the mirrors are rotated
21:46.31CIA-22BRL-CAD: 03brlcad * r36335 10/brlcad/trunk/include/common.h:
21:46.31CIA-22BRL-CAD: wow, HIDDEN has been non-static all this time... 'lint' is apparently no longer
21:46.31CIA-22BRL-CAD: being defined so couple the static setting to whether or not we're compiling in
21:46.31CIA-22BRL-CAD: debug mode or not (so by default, debug mode has non-static for traceability).
21:46.31CIA-22BRL-CAD: this means applications will have to take care to not clobber library symbols.
21:46.57``Erikdrawings like what?
21:48.44``Erikyou could model your 'world' box, mirror and laser in BRL-CAD, then render a bunch of images with the mirror oriented differently and glue the results into either a single image with the line the laser draws, or show an animation of it...
21:48.55CIA-22BRL-CAD: 03bob1961 * r36336 10/brlcad/trunk/src/bwish/ (cmd.c input.c): Changed history_record to history_record_priv to avoid a name collision with libbu.

21:52.58starseekernice
21:57.02brlcadMkop: you might want to take a look at the Ronja project -- that's a project with *very* similar needs to yours, and is one that used brl-cad for modeling, diagrams, animations, and more
21:57.21brlcadhttp://en.wikipedia.org/wiki/RONJA  and  http://ronja.twibright.com/

21:58.28brlcadwasn't just a passing thing

21:58.48brlcadwe attempted for weeks to find the origins, the original author, etc -- as we wanted it to be the main font
21:59.00brlcadMkop: no expectation of replies on irc ;)
21:59.15Mkop(I just know there's nothing more annoying than some n00b coming into IRC, asking a question, and ignoring answers, so I wanted to reasssure you that's not the case)
21:59.17brlcadespecially timely ones, answers can come hours/days later ;)
21:59.58brlcadbe forewarned that brl-cad has a very steep learning curve, but lots of power and capabilities under the hood
22:00.07brlcadthe learning curve cannot be overstated, though ;)
