Full Description see below:

The BRL-CAD package is a powerful Constructive Solid Geometry (CSG) solid modeling systemBRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric representation, with more than 20 years of active development.BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.The entire BRL-CAD package is distributed in source code form.About BRL-CADFor more than 20 years, BRL-CAD has been the primary tri-service solid modeling CAD system used by the U.S. military to model weapons systems for vulnerability and lethality analyses. The solid modeling system is frequently used in a wide range of military, academic, and industrial applications including in the design and analysis of vehicles, mechanical parts, and architecture. The package has also been used in radiation dose planning, medical visualization, computer graphics education, CSG concepts and modeling education, and system performance benchmark testing among other purposes.BRL-CAD supports a great variety of geometric representations including an extensive set of traditional CSG primitive implicit solids such as boxes, ellipsoids, cones, and tori, as well as explicit solids made from closed collections of Uniform B-Spline Surfaces, Non-Uniform Rational B-Spline (NURBS) surfaces, n-Manifold Geometry (NMG), and purely faceted mesh geometry. All geometric objects may be combined using boolean set-theoretic CSG operations including union, intersection, and difference.BRL-CAD has been under active development with a portability heritage that includes systems such as a DEC VAX-11/780 running 4.3 BSD; DECStations running ULTRIX; Silicon Graphics 3030, 4D "IRIS", O2, Onyx, and Origin systems running various versions of IRIX; Sun Microsystems Sun-3 and Sun-4 Sparcs running SunOS; the Cray 1, Cray X-MP, Cray Y-MP, and Cray 2 running UNICOS; DEC Alpha AXP running OSF/1; Apple Macintosh II running A/UX; iPSC/860 Hypercube running NX/2; the Alliant FX/8, FX/80, and FX/2800; Gould/Encore SEL PowerNode6000/9000 and NP1; NeXT workstations; IBM RS/6000; HPPA 9000/700 running HPUX; Ardent/Stardent; Encore Multi-Max; and much more.BRL-CAD is a collection of more than 400 tools, utilities, and applications comprising more than a million lines of source code. The package is intentionally designed to be extensively cross-platform and is actively developed on and maintained for many common operating system environments including for BSD, Linux, Solaris, Mac OS X, and Windows among others. BRL-CAD is distributed in binary and source code form as free open source software (FOSS), provided under Open Source Initiative (OSI) approved license terms.
