Volume Rendering a Cube

There   are two rendering programs, xray and krot. The difference between the two programs is that they have different implementations of the rendering algorithm and offer different options, but both do basically the same thing. Note that xray is highly optimised, both on single-CPU machines and parallel machines, running from two to eight times as fast as krot on a single-CPU machine to four to thirty times as fast on phoenix.
