Recent advances in GPU technology have produced a shift in focus for real-time rendering
applications, whereby improvements in image quality are sought in addition to raw polygon …

We introduce a new concept for accelerating realistic image synthesis algorithms. At the
core of this procedure is a novel physical error metric that correctly predicts the perceptual …

Visibility determination is a key requirement in a wide range of graphics algorithms. This
paper introduces a new approach to the computation of volume visibility, the detection of …

Most previous soft shadow algorithms have either suffered from aliasing, been too slow, or
could only use a limited set of shadow casters and/or receivers. Therefore, we present a …

The calculation of detailed shadows remains one of the most difficult challenges in computer
graphics, especially in the case of extended (linear or area) light sources. This paper …

Visibility computation was crucial for computer graphics from its very beginning. The first
visibility algorithms in computer graphics aimed to determine visible surfaces in a …

Shadow computation in dynamic scenes under complex illumination is a challenging
problem. Methods based on precomputation provide accurate, real-time solutions, but are …

PCT patent application number PCT/US2011/051403 further claims the benefit of the earlier
filing date of US Provisional Application 61/384,284 entitled “System and Method of …

We present two efficient imaged-based approaches for computation and display of high-
quality soft shadows from area light sources. Our methods are related to shadow maps and …

Current graphics hardware can be used to generate shadows using either the shadow
volume or shadow map techniques. However, the shadow volume technique requires …
