As-Rigid-as-Possible Surface Modeling

Modeling tasks, such as surface deformation and editing, can be analyzed by observing the local behavior of the surface. The authors 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 modeling constraints. They devise a simple iterative mesh editing scheme based on this principle, that leads to detail-preserving and intuitive deformations. The algorithm is effective and notably easy to implement, making it attractive for practical modeling applications.
