<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE pkgmetadata SYSTEM "http://www.gentoo.org/dtd/metadata.dtd"> <pkgmetadata> <herd>sci</herd> <longdescription lang="en"> BRL-CAD is a Combinatorial/Constructive Solid Geometry (CSG) solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, and an embedded scripting language. The package is a collection of over 400 tools and utilities. Included is support for various geometric data format conversions, image and signal processing capabilities, ray-tracing based lighting models, network distributed ray-tracing, parallel ray-tracing, animation capabilities, data compression, image handling, and interactive 3-D geometric editing, and also an implementation of Weiler's n-Manifold Geometry (NMG) data structures for surface-based solid models and photon mapping. </longdescription> <use> <flag name="benchmarks"> Run benchmarks during test phase (need test option enabled) </flag> </use> </pkgmetadata>
