Incremental wavelet importance sampling for direct illumination. VRST '07: Proceedings of the 2007 ACM symposium on Virtual reality software and technology.

Abstract: State-of-the-art importance sampling strategies for direct illumination take into account the importance of the incident illumination, ...

Aug 9, 2006 · We introduce the notion of correlated visibility sampling, which considers visibility in partially occluded regions during the sampling process, ...

This paper introduces correlated visibility sampling, a method that additionally takes visibility into account in the sampling process for partially occluded ...

This work aims to take visibility into account in the sampling process for partially occluded regions, thereby improving the quality of the shadowed regions ( ...

This paper proposes a robust and unbiased method for using estimated visibility information to improve the quality of Monte Carlo evaluation of direct ...

Importance sampling would be good in these cases if the sources are hidden, while correlated sampling is efficient if the sources are fully visible. The ...
