Retargeting of Motion Capture Data
Abstract:
The adaption of a given kinematic skeleton to a triangular mesh representing the shape of a human is a task still done manually in most animation pipelines. In this work we propose methods for automating this process. By thoroughly analyzing the mesh and utilizing anatomical knowledge, we are able to provide an accurate skeleton alignment, suited for animating the surface of a virtual human based on motion capture data. In contrast to existing work, our methods on the one hand support the anatomically correct adaption of detailed skeletal structures, but on the other hand are robust against the reduction of the mesh’s tessellation complexity.
