Non-Rigid Registration Under Isometric Deformations
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a robust and efficient algorithm for the pairwise non-rigid registration of partially overlapping 3D surfaces. Our approach treats non-rigid registration as an optimization problem and solves it by alternating ...
Polyhedral Finite Elements Using Harmonic Basis Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological ...
