As many of you may have already noticed via the /. announcement on
Saturday and other news postings, BRL-CAD is now released as open source.
In conjunction with this change, there is a new website:
http://brlcad.org
and
http://sourceforge.net/projects/brlcad/
BRL-CAD is a powerful Combinatorial/Constructive Solid Geometry (CSG)
solid modeling system that includes an interactive geometry editor,
ray-tracing support for rendering and geometric analysis,
network-distributed framebuffer support, image and signal-processing
tools, and an embedded scripting language.
From the /. posting, BRL-CAD is one of the many legacies of the late
Michael Muuss, author of ping. The package began on the PDP-11 and VAX
11/780--before the emergence of ANSI/ISO C language standards--and boasts
one of the first parallel Ray tracers in existence. Today BRL-CAD has over
750,000 lines of source code. It incorporates both 3D modeling and
rendering capabilities, and supports an API for user-developed geometric
analysis applications. It continues to be developed and maintained by the
U.S. Army Research Laboratory
It has been released under the GPL, LGPL, GFDL, and BSD licenses.
Different portions of the package are covered under a different license.
The basic break-down is that the BRL-CAD libraries are LGPL, the
documentation is mostly GFDL (manpages, html, text, etc), the build system
is mostly BSD or in the public domain, and the rest (the applications) is
under the GPL.
Feel free to stop by #bzflag or irc.freenode.net to get involved with the
project. (developers and users welcome, patches very welcome)
Cheers!
Sean Morrison
