Procedural wrinkles generation in the implicit skinning framework

Abstract

Among the procedural skinning methods, implicit skinning [Vaillant et al. 2014] allows to achieve effects like bulge in contact with the use of gradient-based operators, but fine details like wrinkling are missing. Physics-inspired methods make use of the stretch tensor to produce controllable, believable results at acceptable computational cost [Rohmer et al. 2010]. We propose a method that generates plausible and temporally-coherent wrinkles for skeleton-driven 3D animated characters, by extending the implicit skinning framework.
