Enhanced dual quaternion skinning with scale non-compensating joints and support joints

摘要

Methods and systems for two-phase skinning of an object undergoing rigid and non-rigid transformations are disclosed. One method of skinning the object may include separating the object's joint transformations into rigid and non-rigid parts by determining if a joint is scale compensating or scale non-compensating, applying non-rigid joint transformations to the mesh, and applying rigid joint transformations to the mesh. Separation of the object's joint transformations into rigid and non-rigid parts may include determining a bind pose based on an initial configuration of the object's joints and determining an intermediate pose based on the configuration of the object's joints after non-rigid joint transformations are applied to the joints.
