Computes the radiance reflected toward a given direction due to direct illumination of a given surface, at a given point. The point, the surface normal and the direction are expressed in world space. The direction is such as it leaves the surface, and is unit-length. The returned value is a radiance (W.m^-2.sr^-1).

Todo:
Move to caller.

Choose lights based on their occlusion-free contribution to the point being illuminated.

Avoid generating samples for point lights.

This is an auxiliary method used by the final_gathering() method. Computes the radiance reflected toward a given direction due to the photon density on a given surface, around a given point. The point, the surface normal and the outgoing direction are expressed in world space. The outgoing direction is such that it leaves the surface, and it is unit-length. The returned value is a radiance (W.m^-2.sr^-1).

Todo:
Let the user choose between exact and approximate radiance computation.
