Abstract
A possible method for solving the global illumination problem is to use a particle model, where particles perform a random walk through the scene. The proposed algorithm uses this particle model, but computes the illumination of pixels in a direct manner. It will be shown that the algorithm can be derived from a rewritten formulation of the potential equation. This algorithm has some advantages, including the absence of a mesh and the possibility to handle all types of light-surface interactions with the same method.
