All geometric objects may be combined using boolean set-theoretic CSG operations including union, intersection, and difference. 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. 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. 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. military to model weapons systems for vulnerability and lethality analyses. About BRL-CAD For more than 20 years, BRL-CAD has been the primary tri-service solid modeling CAD system used by the U.S. BRL CAD MAC CODEThe entire BRL-CAD package is distributed in source code form. 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 package includes a large collection of tools and utilities including an interactive geometry editor, raytracing and generic framebuffer libraries, a network-distributed image-processing and saignal-processing capability, and an embedded scripting language.The BRL-CAD package is a powerful Constructive Solid Geometry (CSG) solid modeling system BRL-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. ![]() Army Research Laboratory has been developing and distributing the BRL-CAD constructive solid geometry (CSG) modeling package for a wide range of military and industrial applications. There’s also dozens of complex/custom dialogs, windows, and other elements not shown. Both the large red window and the smaller rendering window have graphics contexts implemented via Tk C API, with the larger one providing a custom interactive 3D environment using Tk Pixmap and the smaller displaying an asynchronous incrementally rendered (ray traced) 2D image using Tk_PhotoImageBlock. It calls into Tcl from C for nearly all tasks, including event handling, logging, I/O, and other operations. The Multi-Device Geometry Editor, comprised of over 100K lines of application logic in Tcl/ Tk/ Itcl/ Itk/ Iwidgets, is the heart of BRL-CAD, and its GUI is the primary user interface to the system. To provide for the construction of realistic models of complex objects from a ralttively small set of "primitive shapes", BRL-CAD employs the basic Boolean operations of union, subtraction, and intersection, and assigns reals-world material attributes. 1 BRL-CAD selected as a participant in Google Code-In 2013 Description ![]() News Recent improvements to the Aqua Tk subsystem have made it possible for the first time to get reasonably-operational BRL-CAD running on OS X without the use of X. BRL-CAD, originally by Mike Muuss, is a powerful cross-platform open-source CAD/solid-modeling system that featues 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. ![]()
