This past year, DAC has been giving BRL-CAD something of a face-lift. BRL-CAD enables more than terrain, vehicle, weapon and human modeling - it can now model a range of items from household appliances to NASA tools, securing its place in industry and in history as a fundamental benefit to a variety of engineering analysis work. DAC’s Warfighter and Futures Integration Division provides enhancements, manages new releases and develops custom software to accelerate analysis.īRL-CAD’s source code repository, with more than one million lines of code, is the oldest known continuously developed open source repository in the world. Army Combat Capabilities Development Command, or DEVCOM, Data & Analysis Center, known as DAC, maintains BRL-CAD software functionality for the Army. Army’s Ballistic Research Laboratory, BRL-CAD is the primary tri-service cross-platform solid modeling Computer-Aided Design system used by the military to support analyses of military assets and their environments. Initiated more than 35 years ago at the U.S. That’s why the Army developed BRL-CAD, the first computer model to tackle the need to conceptualize military vehicles. Vulnerability and Lethality, or V/L, modeling helps provide a detailed picture of how potential scenarios and interactions of those components impact mission success. An integral part of preparing and protecting Soldiers is analyzing Soldier equipment, weapons and vehicles. The application side of BRL-CAD also offers a number of tools and utilities that are primarily concerned with geometric conversion, interrogation, image format conversion, and command-line-oriented image manipulation.BRL-CAD shotline analysis and advanced rendering visualization.Īberdeen Proving Ground, Md. Each library is designed for a specific purpose: creating, editing, and ray tracing geometry, and image handling. The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to tinker with software and design custom tools. It does also support boundary representation. This means BRL-CAD can "study physical phenomena such as ballistic penetration and thermal, radiative, neutron, and other types of transport". In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation. In keeping with the Unix philosophy of developing independent tools to perform single, specific tasks and then linking the tools together in a package, BRL-CAD is basically a collection of libraries, tools, and utilities that work together to create, raytrace, and interrogate geometry and manipulate files and data. The entire package is distributed in source code and binary form.Īlthough BRL-CAD can be used for a variety of engineering and graphics applications, the package's primary purpose continues to be the support of ballistic and electromagnetic analyses. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. net /p /brlcad /code /brlcad /trunkĬross-platform (BSD, Linux, Mac OS X, Solaris, and Windows, among others)īRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system.
