Composite Based Refraction For Fur And Other Complex Objects

Composite Based Refraction for Fur and Other Complex Objects

Siggraph 2009

To overcome these problems, a process was developed for "Bolt" which involved exporting 3D data from the render stage so that the calculation of the refraction could be delayed until the composite stage.
