RENDERING CAUSTICS IN COMPUTER GRAPHICS WITH PHOTON MAPPING BY RELAXATION

摘要

The invention relates to a method of rendering caustics in a computer graphics scene. The method comprises obtaining a photon map of said scene, redistributing photons from said photon map into an arrangement with a blue noise spectral signature by performing a relaxation step in respect of each of a number of photons, determining a constraining vector for each of a number of photons and rendering said scene using results from the redistributing photons and/or from determining a constraining vector.
