The Research Of The Space Deformation

Changes in the shape of objects in computer animation is an important research content, Shape changes in the current control means include Morphing technology and space deformation. Deformation in space technology, the user can through the use of points, curves, surfaces, three-dimensional control mesh, or other body has always been a simple control of the complex shape of the object. The complex shape of the object changes into a simple shape of the object changes, so space deformation has an intuitive, natural features. In this paper we first introduced the space-based subdivision surface deformation method of the basic steps,Followed by details on LOOP based on Catmull-Clark subdivision and the subdivision of the space deformation and parameters of the process, LOOP-based segmentation and Catmull-Clark subdivision rules and the rules of space deformation made the comparison, analysis and summary.
