Colliding, Caving & Coloring
Collision Detection Framework Using Model Simplification
A framework that automatically exploits output of a simplification algorithm to construct bounding volume hierarchies for collision detection. Preliminary experiments show very encouraging results.

Optimizing Stereo Video Formats for Projection Based Virtual Reality
Many of today's high-end, projection-based virtual reality systems generate frame-interleaved video for stereoscopic equipment. Integrating LCD shutter glasses, high-end graphics computers, and large-scale projectors is difficult. This sketch identified problems discovered as part of the VR efforts at the Electronic Visualization Laboratory and offers solutions.

3D Painting for Non-Photorealistic Rendering
The 3D Expressive Painter is an interactive, expressive 3D painting and rendering system intended for use in production of hand-drawn natural-media-style animations. By using some imported scene geometry, created in a general-purpose modeller, the system allows interactive placement of paint strokes in 3D. The user is able to rotate the scene, select a suitable viewing angle, and paint from the desired direction, with the depth values for the stroke positions calculated from the imported scene.

Visually Representing Multi-Valued Scientific Data Using Concepts from Painting
Layers of varying brush strokes visually represent 2D images of multi-valued scientific data. Example visualizations display up to eight values simultaneously so that they can be understood in context.
