Surface Deformation Techniques Based On Vector Partition Weaving Cad System

Computing geometry play key role in the generation of realistic images, and also hasimportant application in real-time rendering. In this thesis we present a curved surfacesubdivide method based on norm so that we can obtain a graphics quickly andefficiently.There are two key methods on the research of deformation, based on pure geometrical model and based on physical property. And we present a two-step deformation (global and local) method to cover the existing deformation method on knitwear.Also we discuss the classic model- Peirce's plain stitch model, point out an error in it,and give some useful parameters.We also design and develop the Knitwear-CAD system based on our theory .The result shows that our method has good vision effect and can perform fast rendering, and this CAD system is very useful to practice.
