Interactive ray tracing

Tachyon is fast enough to support ray tracing at interactive rates when run on a large enough parallel computer, or with a simple enough scene. To this end, Tachyon can be optionally compiled with support for the Spaceball 6DOF motion control device. Using the Spaceball, one can fly around in an otherwise static scene. This is accomplished with the `-spaceball serial_port_device` command line parameters.
