| Abstract: | Class_A surface reconstruction is a key part in body exterior design.Because traditional method has some disadvantages like low efficiency,bad flexibility and low surface quality in complicated surface reconstruction,this paper presents a method of Class_A surface reconstruction from point clouds based on NURBS patch,which makes surface design more flexible and direct,improve the reconstruction efficiency and surface quality. |
