Sampling Methods in Ray-Based Global Illumination
… itself with sampling algorithms related to direct lighting, an important subset of global illumination. In this part, we develop two stage importance sampling} to sample the product of the BRDF function and a large light source such as an environment map. We then extend this method to …

Importance Resampling for Global Illumination
… the robustness of this technique on the direct lighting problem and achieve up to a 33% variance reduction over standard techniques. We also suggest using RIS as a default BRDF sampling technique.

Numerical Simulation of Injection of Supercritical Ethylene/Methane into Nitrogen
… results are compared with shadowgraph and direct-lighting imaging data, mass flow measurements, mole fraction measurements and temperature measurements in the jet mixing zone, and pressure distributions within a three-dimensional injector geometry. Qualitative results involving jet …
