Hierarchical Penumbra Casting
We present a novel algorithm for rendering physically-based soft shadows in complex scenes. Instead of casting shadow rays, we place both the points to be shaded and the samples o...

Gradient-based Interpolation and Sampling for Real-time Rendering of Inhomogeneous, Single-scattering Media
We present a real-time rendering algorithm for inhomogeneous, single scattering media, where all-frequency shading effects such as glows, light shafts, and volumetric shadows can ...

Using Wavefront Tracing for the Visualization and Optimization of Progressive Lenses
Progressive addition lenses are a relatively new approach to compensate for defects of the human visual system. While traditional spectacles use rotationally symmetric lenses, pro...

A realistic camera model for computer graphics
Most recent rendering research has concentrated on two subproblems: modeling the reflection of light from materials, and calculating the direct and indirect illumination from lig...

Priority rendering with a virtual reality address recalculation pipeline
Virtual reality systems are placing never before seen demands on computer graphics hardware, yet few graphics systems are designed specifically for virtual reality. An address rec...
