3D Mesh Editing Based on Skeleton

A novel and intuitive method for the interactive editing of 3D meshes is proposed in this paper.This method is based on skeleton.After one region of the model to be deformed and several reference points are determined,a skeleton is created implicitly and automatically through the reference points and the screen.Then the vertices in the region to be deformed are mapped onto the skeleton.To uniformly distribute the distortion brought by the deformation and preserve the details of the deformed region,the points on the skeleton are represented by linear rotation-invariant coordinates,and the skeleton is deformed to the desired position constrained by the target points in the least-squares sense.Deformation of the region can be achieved by reverse mapping the skeleton points onto the region.The skeleton are also can be used to scale and twist the region of the mesh.The interactivity is demonstrated and the method easy to be used by the detail-preserving editing of several models with few time.The new target points for generating animation results are acquired by interpolating between the reference points and the target points.
