Document Type and Number:
Japanese Patent JP7241055
Kind Code:
B2
Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for image rendering. One of the methods includes receiving data describing a scene, wherein the scene comprises one or more light sources and one or more objects having different surface optical properties; receiving a request to render an image of the scene using a multiple importance sampling method that combines a plurality of sampling techniques, wherein each sampling technique uses a different probability distribution to sample a respective fraction of total number of samples; modifying a particular one of the probability distributions to reduce a variance of the multiple importance sampling while holding the respective fractions and the other probability distributions fixed; rendering the scene using the multiple importance sampling using the modified particular probability distribution and the other probability distributions; and outputting the rendered scene in response to the request.
