Understanding the efficiency of ray traversal on GPUs
We discuss the mapping of elementary ray tracing operations-acceleration structure traversal and primitive intersection--onto wide SIMD/SIMT machines. Our focus is on NVIDIA GPUs,...

Object partitioning considered harmful: space subdivision for BVHs
A major factor for the efficiency of ray tracing is the use of good acceleration structures. Recently, bounding volume hierarchies (BVHs) have become the preferred acceleration st...

Data-parallel rasterization of micropolygons with defocus and motion blur
Current GPUs rasterize micropolygons (polygons approximately one pixel in size) inefficiently. We design and analyze the costs of three alternative data-parallel algorithms for ra...

A directionally adaptive edge anti-aliasing filter
The latest generation of graphics hardware provides direct access to multisample anti-aliasing (MSAA) rendering data. By taking advantage of these existing pixel subsample values,...

Efficient ray traced soft shadows using multi-frusta tracing
Ray tracing has long been considered to be superior to rasterization because its ability to trace arbitrary rays, allowing it to simulate virtually any physical light transport ef...

Accelerating shadow rays using volumetric occluders and modified kd-tree traversal
Monte Carlo ray tracing remains a simple and elegant method for generating robust shadows. This approach, however, is often hampered by the time needed to evaluate the numerous sh...

Faster incoherent rays: Multi-BVH ray stream tracing
High fidelity rendering via ray tracing requires tracing incoherent rays for global illumination and other secondary effects. Recent research show that the performance benefits fr...

Embedded function composition
A low-level graphics processor is assembled from a collection of hardwired functions of screen coordinates embedded directly in the display. Configuration of these functions is co...
