Description:

Tachyon is a parallel ray tracing library, for use on distributed memory
parallel computers, shared memory computers, and clusters of workstations.
Tachyon supports MPI for distributed memory parallel computers, threads
for shared memory machines, and can support both simultaneously for
clusters of shared memory machines. Tachyon has been selected for inclusion
in the SPEC MPI2007 benchmark suite. Tachyon supports the typical ray tracer
features, most of the common geometric primitives, shading and texturing
modes, etc. It also supports less common features such as HDR image output,
ambient occlusion lighting, and support for various triangle mesh and
volumetric texture formats beneficial for molecular visualization (e.g.
rendering VMD scenes).
