Abstract In order to preferably realize the constrained deformation of mesh models, an efficient method was proposed based on skeleton-driven by combining affine transformation and generalized metaball deformation technology. A skeleton was created for the region of interest (ROI) to map the vertices in ROI onto the skeleton. A deformable model of rotation, translation and scaling with potential function was selected to set the target values of deformation. The coordinate values of new vertices were computed according to the mapping relationship between original vertices and skeleton to obtain the mesh deformation. In order to solve the distortion in the translation process, a rotating field was established. The experiment results show that the proposed method is efficient and intuitive to maintain the local details well, and can be flexibly applied to the model deformations of rotation, translation, scaling and other operations.
