Ph. D. Student
Information
I was a student at University of Montreal in computer graphics. I'm now
an assistant professor at "Université de Sherbrooke" in
the department "de mathématiques
et d'informatique" since June 2000.
I'm working on a framework for the specification and manipulation of
models of systems using chains on cell complexes.
My advisor was Neil
Stewart.

Chain System
There is a public version of the implementation of the framework : Chain
System. It provides
an easy way to describe the behavior of objects, for example, using
physical simulation. It permits
the specification and manipulation of attributes associated with topological
elements of systems.
It uses a simple API describe in A
framework for system specification using chains on cell complexes
The programe, in Visual C++ 5.0, includes two examples : a waving flag
and Catmull-Clark
subdivision process.
If you use the Chain System, develop new examples, modify the program,
please, let me know.
