Weight assignment method suitable for SBS mesh deformation
摘要
Abstract
This paper presents a weight assignment method suitable for Spherical Blend Skinning(SBS)mesh deforma-tion. The projection on the bone of the vertex is used as the initial weight of this bone to solve heat equilibrium equation. The vertices controlled by each bone are taken as a cluster and the weight related to this bone of the vertices that are on the border of the cluster is reduced. Then the weight of vertices of this cluster except those are on the border is interpolated based on neighbors. The method can suppress the problem of over-weighting occurring at the intersection part of the body, making the weights conform to the topology of mesh and smoothly changed. The experiences show that the mesh is natu-rally and smoothly deformed by SBS with the weights computed by this method.关键词
