3D Digitizing Made Easier by Unstructured Sketching
Feature-Based Haptic Rendering: Architecture, Protocol, and Application
The user sketches a few strokes and sees a 3D "clay" prototype. When the user adds more random strokes, the prototype surface automatically adapts to follow the pen, and the crease and corner features are automatically detected and aligned.

A Model for Managing Level of Detail With Head-Tracked Peripheral Degradation
Since haptic rendering requires a very high control rate, it must be separated from graphic rendering and modeling processes. Feature based haptic rendering is a new, general protocol for data exchanging between such decoupled processes.

A psychophysically based model for reducing peripheral detail with head-tracking. The model indicates that central detail of 30 horizontal and vertical degrees is adequate. This sketch presented experimental confirmation.

Simplification of architectural, CAD, and other indoor models by dynamically inserting textures into the model. This approach eliminates many of the geometric and temporal discontinuities present in texture-based simplification.
