Vectorized Production Path Tracing
Describes an efficient production path-tracing rendering system that is vectorized. It is the first in its class to leverage SIMD hardware units of modern CPUs throughout. We showcase performance results of rendering a few production scene assets.
Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur
Describes an efficient ray-tracing system for hair and fur geometry, including many smart ways to build good acceleration structures. We use a Monte Carlo path tracer to render a few examples of hairy production models.
Point-Based Global Illumination Directional Importance Mapping
Siggraph Talk 2012
Describes a point based global illumination extension to embrace physically based shading.
Coherent Out-of-Core Point-Based Global Illumination
Describes a point based global illumination system that can efficiently handle extremely complex scenes.
Soft Shadows by Ray Tracing Multilayer Transparent Shadow Maps
Describes a soft-shadowing algorithm that is physically correct, efficient and can be applied to very complex scenes.
An Approximate Global Illumination System for Computer Generated Films
Describes the academy award winning global illumination rendering system that was used in the making of the movie Shrek 2, and many more movies since...
