Raytracing Page

• There's a free, powerful ray tracing program called POV-Ray (for Persistence of Vision Ray Tracer), available for almost every platform at http://www.povray.org. It comes in both binary and source form, and their web page has links to other ray tracing information as well as a beautiful gallery of images created with POV-Ray.
• Radiance ( http://radsite.lbl.gov/radiance/HOME.html ) is a ray tracer geared towards analysis of lighting, rather than just making pretty pictures.
• Rayshade ( http://www-graphics.stanford.edu/~cek/rayshade/rayshade.html) is a fast ray tracer with support for parallel processing.
• The Blue Moon Rendering Tools ( http://www.seas.gwu.edu/student/gritz/bmrt.html) is a ray tracer that implements the Renderman shading language. This language is used by such companies as Industrial Light & Magic and Pixar to create just about every mind-blowing computer special effect in the last twenty years. The professional software is rather expensive, so this free package by Larry Gritz is an ideal way to play with the Renderman language.
• A good general ray tracing page can be found at http://www.cm.cf.ac.uk/Ray.Tracing/, with links to ray tracing information and more ray-tracing software.
• The Ray Tracing News ( http://www.acm.org/tog/resources/RTNews/html/index.html ) is a electronic publication with lots of good info on Ray Tracing.
