Broad-phase collision detection using semi-adjusting BSP-trees
The broad-phase step of collision detection in scenes composed of n moving objects is a challenging problem because enumerating collision pairs has an inherent O(n2) complexity. S...

Real-time relief mapping on arbitrary polygonal surfaces
This paper presents a technique for mapping relief textures onto arbitrary polygonal models in real time. In this approach, the mapping of the relief data is done in tangent space...

Epipolar sampling for shadows and crepuscular rays in participating media with single scattering
Scattering in participating media, such as fog or haze, generates volumetric lighting effects known as crepuscular or god rays. Rendering such effects greatly enhances the realism...

Incorporating dynamic real objects into immersive virtual environments
We present algorithms that enable virtual objects to interact with and respond to virtual representations, avatars, of real objects. These techniques allow dynamic real objects, s...

Image-based objects
We present a compact, image-based representation for threedimensional objects with complex shapes that can be rendered with correct perspective from arbitrary viewpoints using a l...
