Interactive water streams with sphere scan conversion
Fluid simulations require efficient dynamics, surface extraction and rendering in order to achieve real time interaction. We present a novel technique for the surface extraction ...

Matching Photometric Observation Vectors with Shadows and Variable Albedo
We describe a procedure to solve the basic problem of Variable Lighting Photometric Stereo – namely, recovering the normal directions and intrinsic albedos at all visible points...

A Spatio-Temporal Modeling Method for Shape Representation
The spherical harmonic (SPHARM) description is a powerful surface modeling technique that can model arbitrarily shaped but simply connected three dimensional (3D) objects. Because...

Evaluation of supra-threshold perceptual metrics for 3D models
Measures of dissimilarity of 3D models are necessary in a wide range of applications such as geometry compression, simplification, and 3D model retrieval. In many cases a metric ...
