U.S. Army Research Lab Opens BRL-CAD Source 209
brlcad writes "After 20 years of active development under a proprietary government license agreement,
the BRL-CAD
solid modeling suite has just been released as
Open Source software.
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
and its partners. Various
portions of the package are distributed under the
GPL,
LGPL,
GFDL, and
BSD licenses."
