The photon mapping method

We do not explain everything here. Please go to the additional ressources section (below) to get more information.

General principle

The photon mapping method is a two-pass method: a first pass propagates and stores photons in a 3D data structure, and a second pass gathers energy toward the eye using this information.

Additional ressources

To be read:

• the book from Henrik Wan Jensen
• the D7.3 deliverable of the RealReflect project explains with some more details the implementation of the method.
• this excellent survey of the photon mapping method
