Hierarchical mesh-to-points as-rigid-as-possible registration

Surface registration is a fundamental problem in computer graphics and computer-aided design. The consists finding deformation from one surface to another that preserves some properties. For instance, our inverse engineering context, we aim at the best, as isometric possible, map between an input triangular model, large point cloud acquired on actual mechanical part being processed. Existing solutions are not able handle very models with good level of precision. We propose method which accurate fast. Our solution combines efficient iterative energy minimization scheme hierarchical decomposition geometry. experiments show obtain fast algorithm compared state-of-the art method, while keeping its numerical accuracy.
