Skinning: real-time shape deformation

A planar parameterization of 3D surfaces is useful for many applications, The applicability of the parameterization depends on how well it preserves the surface geometry (angles, distances, and areas). For most surface meshes there is no ...

We continue the study of rational envelope (RE) surfaces. Although these surfaces are parametrized with the help of square roots, when considering an RE patch as the medial surface transform in 4D of a spatial domain it yields a rational parametrization ...

Geometric skinning techniques, such as smooth blending or dual-quaternions, are very popular in the industry for their high performances, but fail to mimic realistic deformations. Other methods make use of physical simulation or control volume to better ...
