Extending implicit skinning with wrinkles

Abstract

We propose a wrinkle system that takes as input the fields created in the implicit skinning framework, calculates the angle between their gradients and builds a scalar angle field. Its gradient resembles plausible wrinkle directions. The system is procedural and works as a post process by projecting vertices in a wrinkle field constituted of convolution surfaces.

Survey of Skinning Method in 3D Character Animation

“…Ming Gao [5] proposes a method that can generate physical skinning animations of skeleton-driven characters. Fabio Turchet [6] proposes an extension of implicit skinning with wrinkles, this large amount of parameters will allow users to adjust the behavior of the wrinkles then find the solution. M.P.…”
