Abstract
Discrete geometry is a central and challenging issue from the modeling and
computational perspective in several sciences, including computer graphics. In
this talk, we will explain how our initial variational approach to surface
smoothing has led us to investigate a discrete theory of differential forms and
vector fields on piecewise linear n-manifolds. We will show how some recent
theoretical developments can be directly used in important applications such as
intrinsic parameterization, isotropic and anisotropic smoothing and remeshing,
generalized barycentric coordinates, as well as thin-shell simulation.
About the Speaker
Mathieu Desbrun is an Assistant Professor of Computer Science at the
University of Southern California, and a Visiting Associate at Caltech.
His research interests revolve around geometry, and particularly, the
study of discrete geometry. This vast area includes animation and
simulation of 3D objects, processing of polygonal meshes (compression,
curvature analysis, remeshing, etc), haptics, as well as more
theoretical work on the foundation of computations on discrete manifolds
(Discrete Exterior Calculus). Mathieu received the NSF Young
Investigator Award in 2001 and the SIGGRAPH Significant New Researcher
Award in 2003.
