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> <upstream> <remote-id type="sourceforge">brlcad</remote-id> </upstream> </pkgmetadata>
