Hemispherical integrals are important for the estimation of direct lighting which has a major impact on the results of global illumination. This work proposes the population Monte Carlo hemispherical integral (PMC-HI) sampler to improve the efficiency of direct lighting estimation. The sampler is unbiased and derived from the population Monte Carlo framework which works on a population of samples...
Except for the first frame, a population Monte Carlo image plane (PMC-IP) sampler renders with a start-up kernel function learned from previous results by using motion analysis techniques in the vision community to explore the temporal coherence existing among kernel functions. The predicted kernel function can shift part of the uniformly distributed samples from regions with low visual variance to...
