What is BRL-CAD?

BRL-CAD is a powerful open source cross-platform solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, a system performance analysis benchmark suite, geometry libraries for application developers, and more than 30 years of active development.

Highlights

Cross platform

Cross platform

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.

Trusted by U.S Military

Trusted by U.S Military

BRL-CAD is choice of U.S Military. For 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.

Since 1979

Since 1979

Mike Muuss began the initial architecture and design of BRL-CAD back in 1979. Development as a unified package began in 1983. The first public release was made in 1984. BRL-CAD became an open source project on 21 December 2004.

The project aims to create a geometry editor for BRL-CAD. The project should ideally be an improvement over the existing editors MGED and Archer.
