The Area Sampling Machine
Tracing a ray in a typical image synthesis system accomplishes two tasks: it samples in the ray direction for a visible object, and then determines the shading at that sampled point. The sampling process can be thought of as a visibility test along the path of the ray having zero cross sectional …
