Abstract

Based on the grid point of NURBS curved surfaces and the data structure constructured by data net work in link list, a hidden line algorithm for trimed surfaces is proposed in this paper. The subdivision of image space or/and object space and the sorting of patches are omitted.A neighbor area search method is used to decide the visibility of grid points.
