Multiple Vertex Next Event Estimation for Lighting in dense, forward-scattering Media
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a new technique called Multiple Vertex Next Event Estimation, which outperforms current direct lighting techniques in forward scattering, optically dense media with the Henyey-Greenstein phase function. Instead ...
Line Integration for Rendering Heterogeneous Emissive Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Emissive media are often challenging to render: in thin regions where only few scattering events occur the emission is poorly sampled, while sampling events for emission can be disadvantageous due to absorption in dense ...
