POV-Ray 2.2 Persistence of Vision Ray Tracer The Persistence of Vision Ray Tracer (POV-Ray) is a copy- righted freeware program that allows a user to easily cre- ate fantastic, three dimensional, photo-realistic images on just about any computer. POV-Ray reads standard ASCII text files that describe the shapes, colors, textures and lighting in a scene and mathematically simulates the rays of light moving through the scene to produce a photo- realistic image!
