| Abstract: | Based on the theory of Marching Cubes,a new method about spatial points reduction is provided in this paper.This method can availably reduce the points and delete noise on the condition of preserving accuracy.The difficulty of searching contour line can be reduced greatly on basis of cubes.The principle is simple,and the algorithm can be carried out easily.The experiment shows that this method can gain satisfying results.Ke |
