A variety of ray-racers for analyzing geometry for visualization or geometric purposes.New geometry converter for the United Kingdom’s INTAVAL format from Her Majesty’s Ministry of Defence.Importers include CY, DXF, ENF, EUCLID, FAST4, NASTRAN, PLY, STL, TANKILL, and VIEWPOINT.

Geometry converters: Exporters include DXF, EUCLID, NFF, OBJ, STL, TANKILL, VRML, X3D, and OpenGL vertex array buffers.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. Signal processing utilities manipulate raw data streams according to specified criteria.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.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.

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).

Archer is a GUI-based solid model viewer and editing tool.

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.

Network Package Library implements a client-server network connection that multiplexes synchronous and asynchronous messages across stream connections.

Geometry Modeling Kernel provides fundamental geometric representation, ray-trace analysis, and geometric processing capabilities via a high-performance procedural CĪPI designed for multithreaded processing and fast ray-intersection evaluation.

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.
