getGlobalRadiance(ShadingState state)
This is an optional method for engines that contain a secondary
illumination engine which can return an approximation of the global
radiance in the scene (like a photon map).

Color |
getIrradiance(ShadingState state,
Color diffuseReflectance)
Return the incomming irradiance due to indirect diffuse illumination at
the specified surface point.

init(Options options,
Scene scene)
Initialize the engine.
