(LaTeX) Abstract:

This paper describes a new acceleration technique for rendering algorithms
like path tracing, that use so called gathering random walks.
Usually in path tracing, each traced path is used in order to compute a
contribution to only a single point on the virtual screen. We propose to
combine paths traced through nearby screen points in such a way that
each path contributes to multiple screen points in a provably good way. Our
approach is unbiased and is not restricted to diffuse light scattering. It
complements previous image noise reduction techniques for Monte Carlo
ray tracing. We observe speed-ups
in the computation of indirect illumination of one order of magnitude.

Keywords:

Three-Dimensional Graphics and Realism, Color, shading, shadowing, and texture, Ray tracing, Monte Carlo methods
