A spherical gaussian framework for bayesian Monte Carlo rendering of glossy sur...
Marques, Ricardo; Bouville, Christian; Ribardiére, Michael; Bouatouch, KadiThe Monte Carlo method has proved to be very powerful to cope with global illumination problems but it remains costly in terms of sampling operations. In various applications, previous work has shown that Bayesian Monte Carlo can significantly outperform importance sampling Monte Carlo thanks to a more effective use of the prior knowledge and of the information brought by the samples set. These good results hav...
Spherical Fibonacci point sets for illumination integrals
Marques, Ricardo; Bouville, Christian; Ribardiére, Michael; Santos, Luís Paulo; Bouatouch, KadiArticle first published online: 24 JUL 2013 ; Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value of spherical integrals (e.g. illumination integral). The common approach for generating QMC sampling patterns for spherical integration is to resor...
