| Abstract: | Based on edge collapse mesh simplification,an interactive 3D shape deformation algorithm is proposed.By collapsing edges of triangle mesh to extract key points from original 3D model,the reduced 3D model is generated,and then fixed or movement constraints are forced to the reduced model interactively.By constructing and solving nonlinear optimization equation,optimal solutions of affine transformations are found for all key points.On the basis of affine transformations of key points,deformation mappings for... |
