Lecture 4 - Mesh Processing

Abstract : The goal of this lecture is to manipulate a 3D mesh. This includes the loading and display of a 3D mesh and then the processing of the mesh. This processing is based on computations involving various kinds of Laplacians. These Laplacians are extensions of the classical second order derivatives to 3D meshes. They can be used to perform heat diffusion (smoothing), compression and parameterization of the mesh.
