Description:

The Persistence of Vision(tm) Ray-Tracer creates three-dimensional,
photo-realistic images using a rendering technique called ray-tracing.
It reads in a text file containing information describing the objects
and lighting in a scene and generates an image of that scene from the
view point of a camera also described in the text file. Ray-tracing is
not a fast process by any means, but it produces very high quality
images with realistic reflections, shading, perspective and other
effects.
