BRL-CAD
The BRL-CAD package is a powerful Constructive Solid Geometry
(CSG)
solid modeling system with over 20 years development and production use
by the U.S. military.
BRL-CAD includes an interactive 3D solid geometry editor, a
network-distributed symmetric multiprocessing high-performance
ray-tracer, network-distributed framebuffer support, image and
signal-processing tools, ray-tracing support for rendering and
geometric analysis, path-tracing and photon mapping support for
realistic image synthesis, animation capabilities, ray-tracing and
numerical processing libraries, a system performance analysis benchmark
suite, an embedded scripting interface, and a robust high-performance
geometric representation and analysis library.
The solid modeling system is frequently used in a wide range
of military and industrial application 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 includes a number of
projects:
- Geometry Modeling Kernel provides fundamental geometric
representation, ray-trace analysis, and geometric processing
capabilities via a high-performance procedural C
API designed for multithreaded processing and fast ray-intersection
evaluation
- Network Package Library implements a client-server network
connection that multiplexes synchronous and asynchronous messages
across stream connections
- Multiple-device Geometry EDitor (MGED) is an interactive
solid modeler that provides a graphical user interface as well as a
robust text-based command interface
- Archer is a GUI-based solid model viewer and editing tool
- The Advanced Distributed Ray-Tracer (ADRT) includes a high
performance triangle intersection engine (libtie), a real-time
ray-tracer (ISST), and a path-tracer for realistic image synthesis
(RISE)
- The BRL-CAD Benchmark Suite is a system performance
analysis benchmark that tests the performance of a given system's CPU,
memory, cache coherency, kernel context switching, and compiler
optimization capabilities
- Image Processing Tools support several common formats
including PNG, RLE, PPM, PS, and SUN images as well as a variety of
image processing tools that work on raw image data
- Signal processing utilities manipulate raw data streams
according to specified criteria. These manipulations include
data conversion and filtering capabilities as well as various
transformations including discrete and non-discrete Fast Fourier
transforms (FFT) and wavelet decomposition
- Geometry converters: Exporters include DXF, EUCLID, NFF,
OBJ, STL, TANKILL, VRML, X3D, and OpenGL vertex array
buffers. Importers include CY, DXF, ENF, EUCLID, FAST4,
NASTRAN, PLY, STL, TANKILL, and VIEWPOINT
- New geometry converter for the United Kingdom's INTAVAL
format from Her Majesty's Ministry of Defence
- A variety of ray-racers for analyzing geometry for
visualization or geometric purposes
