Compact Precomputed Voxelized Shadows
A novel data structure for precomputed shadows, enabling high-quality filtered shadows for any point in the scene. Compared to a standard shadow-map, the structure is two to three orders of magnitude more compact at high resolutions, while allowing large PCF filters at competitive speeds.

Instant Convolution Shadows for Volumetric Detail Mapping
This paper presents interactive rendering of high-quality dynamic scenes featuring translucent procedural volumetric detail with all-frequency soft shadows. The technique applies slab-based front-to-back traversal with iterative convolution using efficient convolution kernels, allowing real-time modification of all rendering parameters, working simultaneosly on surfaces and volumes.

Dynamic Ray Stream Traversal
While each generation of processors achieves larger caches and wider vector units, external memory bandwidth increases at a slower pace. To exploit these trends in ray tracing, this paper presents an efficient algorithm for traversing large packets of rays against a BVH in a way that groups coherent rays during traversal.

A Practical Algorithm for Rendering Inter-Reflections With All-Frequency BRDFs
An algorithm for rendering inter-reflection effects with all-frequency BRDFs, based on spherical Gaussian representation of BRDFs. It is accurate for a wide range of BRDFs.
