Path Traced Subsurface Scattering using Anisotropic Phase Functions and Non-Exponential Free Flights|
Magnus Wrenninge, Ryusuke Villemin, Christophe Hery
With the recent move to path tracing for both surface and volume rendering, subsurface scattering has been one of the last light transport modes to rely on empirical or approximate models. Although rendering of subsurface scattering using path tracing is conceptually simple, making the model artist friendly is not. Our new ... more

Production Volume Rendering|
Julian Fong, Magnus Wrenninge, Christopher Kulla, Ralf Habel
This course provides an overview of production volume rendering, focused on path tracing. The course will describe practical fundamentals for adding volume rendering to an existing path tracer, cover a complete range of volume integration scenarios and techniques, and describe in detail recent production-proven techniques for optimizing volume rendering.
