Computer Graphics: The Art of ray Tracing
Examples of POV-Ray

The Kettle, by Mike Miller

Ray tracing is a technique for modeling realistic lighting effects in 3D computer graphics. The path of each light ray that enters the observer's eye is calculated. Based on the characteristics of the original light source and objects in the path, the intensity and color of the light ray is determined. Persistance of Vision Ray Tracer (POV-Ray) is a powerful software program that enables the user to create ray traced images using a simple programming language. Below are examples of what POV-Ray can do.
