Face Animation
Video: Making Faces. An actress reads from a script designed to provide maximal phonetic coverage (we were planning to do automatic lip sync as a follow-on research project but never got around to it). Hence the…
Procedural Modeling
Using a piecewise parametric representation, we have made complex procedural objects that have a memory footprint of just 7-11 KBytes, which render at approximately 20 million triangles/ sec. on an NVidia 6800 GPU.
Symbolic Differentiation
The D* algorithm computes efficient symbolic derivatives for these functions by symbolically executing the expression graph at compile time to eliminate common subexpressions and by exploiting the special nature of the graph that represents the…
D* Symbolic Differentiation Code and Geometric Modeling and Dynamics Examples
The download includes the D* executable and full source code for the following: basic D* programming examples, Lagrangian dynamics, and a basic interactive geometric modeling tool. This is unsupported code but if you find bugs…

Symbolic Differentiation an HLSL Language Feature
Derivatives arise frequently in graphics applications. To meet this need we have added symbolic differentiation as a built-in language feature in the HLSL shading language.
