A high performance parallel ray tracing system supporting MPI and
Tachyon implements all of the basic geometric primitives such as
triangles, planes, spheres, cylinders, etc. Some of the goals in
developing Tachyon were to make it fast and for it to parallelize
well. These are what set it apart from more full-featured programs
like POV-Ray, Rayshade, and others. Tachyon supports enough features
to be an excellent alternative to slower programs for demanding
animation and scientific visualization tasks.
