  • Combining sampling arrangements and distributions for stochastic integration in rendering
    Patent number: 9741153
    Abstract: Systems, methods and articles of manufacture for sampling visual characteristics of a three-dimensional scene. Embodiments include collecting a plurality of samples within the three-dimensional scene. Upon determining that a combined stratified importance sampling algorithm will result in reduced error for a rendered image of the three-dimensional scene, embodiments collect the plurality of samples using the combined stratified importance sampling algorithm, and otherwise the plurality of samples are collected using a stratified sampling algorithm. The combined stratified importance sampling algorithm integrates an antithetic sampling algorithm. One or more lighting effects for the three-dimensional scene are simulated based on the plurality of samples and data describing one or more light sources for the three-dimensional scene. Embodiments further include rendering the image based on the simulated one or more lighting effects and data describing characteristics of the three-dimensional scene.
