Real-Time Importance Sampling of Dynamic Environment Maps

Instant Radiosity [Kel97] (IR) uses the same random distribution of particles, which in contrast to Photon Mapping approximate the radiance field in the scene and are therefore

The introduced MIP map-based approximation allows us to use the generated environment maps as a representation of real area light sources of arbitrary form and coloring while

This paper proposes a modification of the filtered importance sampling (FIS) method, and improves the quality of virtual spherical Gaussian light (VSGL) based real-time glossy

Also in large scenes, when light particles (photons) cannot find the camera, all the strategies based on light sub-paths make almost no contribution and bidirectional algorithms

We introduce a Monte Carlo importance sampling method for integrands composed of products and show its application to rendering where direct sampling of the product is often
