As-Conformal-As Possible Surface Registration
We present a non-rigid surface registration technique that can align surfaces whose sizes and shapes are different to each other, while avoiding mesh distortions during deformation. The registration is constrained locally asconformal-as possible such that angles of triangle meshes are preserved yet local scales are allowed to change. Based on our conformal registration technique, we devise an a...

متن کاملAs-rigid-as-possible surface modeling
Modeling tasks, such as surface deformation and editing, can be analyzed by observing the local behavior of the surface. We argue that defining a modeling operation by asking for rigidity of the local transformations is useful in various settings. Such formulation leads to a non-linear, yet conceptually simple energy formulation, which is to be minimized by the deformed surface under particular...
متن کاملNon-Rigid Registration Under Isometric Deformations
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 between correspondence and deformation optimization. Assuming approximately isometric deformations, robust correspondences are generated using a pruning mechanism based on geod...
متن کاملImplementing As-Rigid-As-Possible Shape Manipulation and Surface Flattening
This article provides a description of an “as-rigid-as-possible shape manipulation” implementation that is clearer and easier to understand than the original. While the original paper used triangle-based representation, we use edgebased representation to simplify the coding. We also extend the original algorithm to allow the user to place handles on arbitrary positions of the mesh. In addition,...
