Tachyon for Mac

Tachyon is a multiprocessor ray tracing system which can be used as a standalone program, or as a library within other programs. It supports almost any Unix-like system, Windows, MacOS-X, BeOS, and VMS, as well as several embedded systems and high end supercomputers. Tachyon is written in C, uses POSIX threads and/or MPI for utilization of multiple processors, and can also run on uniprocessor machines. Tachyon is easy to port to new machines, and is fast, using ray tracing acceleration schemes to achieve good performance on very complex scenes. (It will handle scenes containing more than 1,000,000 objects on a fairly average computer)
