Discrete Willmore Flow
(The Eurographics Association, 2005)
The Willmore energy of a surface, R(H2 -K)dA, as a function of mean and Gaussian curvature, captures the deviation of a surface from (local) sphericity. As such this energy and its associated gradient flow play an important ...
An Image Processing Approach to Surface Matching
(The Eurographics Association, 2005)
Establishing a correspondence between two surfaces is a basic ingredient in many geometry processing applications. Existing approaches, which attempt to match two meshes directly in 3D, can be cumbersome to implement and ...
