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 all nodes in original model are calculated. Examples show that edge collapse mesh simplification can be effectively used to reduce the number of polygons and computation, and combining it with nonlinear optimization solution, a real-time display and detail-preserved 3D shape deformation can be realized interactively.
