 Model Simplification Using Directional Clustering

Enhancement of model simplification with a non-topographic metric and a directional clustering algorithm that uses both geometry compression and real-time, animation-dependent calculation.

 Intelligent Transmission of 3D Polygonal Models 

A framework offering improved Level of Detail handling in VRML. Models are decomposed into fragments, which are transmitted and rendered as required to meet user-specified resolution requirements.
