Since 1979, the U.S. Army Research Laboratory (formerly the Ballistic
Research Laboratory) has been developing the
constructive solid geometry (CSG) modeling package for a wide range of
military and industrial applications. The strength of the package
lies in its ability to build realistic models of complex objects from
a relatively small set of "primitive shapes" by employing the basic
Boolean operations of union, subtraction, and intersection and by
assigning real-world material attributes.
The package comprises a large collection of tools, utilities, and libraries including an interactive geometry editor, ray-tracing and generic framebuffer libraries, a network-distributed image-processing and signal-processing capability, and an embedded scripting language.
BRL-CAD has continued to mature in performance and
utility, developers have strived to keep the package approachable and
easy to use, as evidenced by the package’s dual command formats, its
newly renovated graphical user interface (GUI), and its customization
potential through user scripting.
In addition, a multivolume tutorial series is being developed to
assist users in a variety of
BRL-CAD areas and applications.
The "Introduction to
MGED," which is the second volume in the
series, is intended to provide new users with a basic understanding of
Multi-Device Geometry Editor (
MGED), which is the
heart of the
BRL-CAD package. Other volumes focus on
installation procedures, advanced features, and programming.
