"""The Persistence of Vision Raytracer 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.
