A Hardware Unit for Fast SAH-Optimised BVH Construction
This paper presents a novel microarchitecture for efficient construction of SAH-optimised bounding volume hierarchies (BVHs) for ray-tracing and considers its potential utility in a heterogeneous graphics processor.

Cardinality-Constrained Texture Filtering
A method for combining optimized sets of texels from multiple levels in a mipmap pyramid to accurately reproduce filter kernels. Whereas samples from a mipmap are typically interpolated, this approach views sampling a mipmap as a problem of function approximation. Using half the texture bandwidth as trilinear interpolation, it generates clearer images.

Analytic Displacement Mapping Using Hardware Tessellation
A comprehensive solution for displacement mapping using GPU hardware tessellation. The analytic displacement function obviates the need for normal maps, allowing faster rendering and instant authoring.

A Sort-Based Deferred Shading Architecture for Decoupled Sampling
This paper presents a novel hardware architecture for efficient stochastic rendering and shading with decoupled sampling of shading and visibility in future GPUs. The architecture reduces off-chip memory bandwidth to less than 50% of previous solutions, while avoiding overdraw and rasterizing the scene only once.
