Interface SurfaceLight

All Superinterfaces:

Light

All Known Implementing Classes:

RectangularLight, SphericalLight

public interface SurfaceLight

extends Light

A SurfaceLight implementation represents a light that can be represented by some (possible infinite) set of other Light objects. A correct implementation should be able to return any number of samples (Light objects) that are well distributed and representitive of the surface. Factoring in number of samples to create an intensity value for each sample will be handled by the ray tracing engine.
