Software Requirements

Radiosity methods store energy (in some form) on the surfaces of the environment. This is usually done by chopping the environment into pieces by creating a mesh for each surface. Each element of the mesh has some requirements on it.

• It should be possible to get geometry info from the element (area, corners, normal, random points)
• It should be possible to store a spectrum (or RGB) on the element.
• It should be possible to subdivide the element into smaller elements.
• It should be possible to get the average reflectance of the element.
