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.
