Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
Photon Beam Diffusion: A Hybrid Monte Carlo Method for Subsurface Scattering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present photon beam diffusion, an efficient numerical method for accurately rendering translucent materials. Our approach interprets incident light as a continuous beam of photons inside the material. Numerically ...
