摘要
Disclosed relates to a method for skinning technology based on extended PBD and for weight retargeting in character animation. A corresponding tetrahedral mesh is generated for a given triangular mesh; a tensile constraint, a volume constraint, a self-collision constraint and an energy constraint of the extended PBD are initialized for the tetrahedral mesh, and vertex weights of the triangular mesh and the tetrahedral mesh are optimized simultaneously; the deformations of the triangular and the tetrahedral meshes are implemented through LBS technique; deformation results of the LBS are optimized through extended PBD; the joint region of the triangular mesh is smoothed through a Laplacian smoothing; bi-harmonic distance fields of the original mesh and a new mesh are calculated respectively, and two corresponding vertices of the mesh are given and a prediction function is defined; A weight retargeting algorithm is implemented in the present application and has a good practicability.
