Photonmapping

(Photon Mapping) : was introduced in 1994 by Henrik Jensen (http://graphics.ucsd.edu/~henrik/)

And, it is an algorithm for calculating the global illumination.

*Its' purpose, as efficiently as possible; is to calculate the global illumination of a scene.

The algorithm runs in 2-phases. In the first phase, the photon map is created and then in the second phase by rendering, with the help of the photon map, (the actual image.) This is determined at a certain point in the image, the energy of the photons due to the photon map. Sun can be achieved by adding the indirect, calculated from the photon map, and calculated directly to determine the global illumination of the scene.
