Temporal Thumbnails: rapid visualization of time-based viewing data
We introduce the concept of the Temporal Thumbnail, used to quickly convey information about the amount of time spent viewing specific areas of a virtual 3D model. Temporal Thumbn...

Direct Volume Rendering with Shading via Three-Dimensional Textures
A new and easy-to-implement method for direct volume rendering that uses 3D texture maps for acceleration, and incorporates directional lighting, is described. The implementation,...
