Global Illumination and Occlusion

Practical Dynamic Parallax Occlusion Mapping An improved parallax occlusion mapping algorithm for dynamic real-time lighting of surfaces including soft shadows, a directable LOD system, and robust critical height field-ray intersection computation.

Correlated Visibility Sampling for Direct Illumination Using the Metropolis-Hastings algorithm to sample according to the triple product of incident illumination, BRDF, and visibility.

Precomputed Light Sets for Fast High-Quality Global Illumination Fast high-quality global illumination based on instant radiosity is achieved by using local light sets, which were generated during a preprocessing stage and contain visibility information.
