Rossignac,J: Shape Comparison, Simplification, and Compression

College of Computing, Georgia Institute of Technology, USA


How to measure and visualize the discrepancy between two or more shapes?
How to optimize the deformation that morphs between two given shapes?
How to simplify a shape by removing small or sharp features without altering the regular portions?
How to compute the control mesh of a subdivision surface that approximates a given shape?
How to compress and decompress such a control mesh? How to recover its sharp edges?
The speaker will discuss the relations between these questions and propose some answers.
