Directional field design on dynamic and rigged meshes

Abstract

We present a method for designing directional fields on discrete surfaces, that align to the movement of a dynamic mesh, which is animated by rigging and skinning. We exemplify how aligning the mesh to the direction of the movement serves to reduce discretization artifacts in the deformation. Our method designs a non-orthogonal and non-uniform field that respects creases and the movement patterns of the mesh, and uses it to create quad meshes.
