Simulating Multiple Scattering in Hair Using a Photon-Mapping Approach
Physically accurate rendering of hair volumes requires simulation of multiple scattering. This paper proposes a 5D photon-mapping approach that efficiently approximates the contribution of multiple scattering in hair.

Statistical Acceleration for Animated Global Illumination
Acceleration of animated indirect illumination computations by rendering fast but noisy solutions followed by statistics-based denoising. The resulting animation has low computational cost and reduced noise.

Multidimensional Lightcuts
Multidimensional lightcuts efficiently and scalably render sophisticated effects including motion blur, depth of field, antialiasing, and volume scattering. Key components include an implicit hierarchy, analytic bounds, and a perceptual metric.

Direct-to-Indirect Transfer for Cinematic Relighting
A real-time GPU relighting engine for multiple-bounce indirect illumination supporting complex scenes and procedural light shaders. The method efficiently precomputes and compresses the transfer from direct to indirect illumination.
