摘 要
Marching Cubes(MC)算法是一个被广泛应用的体数据等值面抽取算法H本文提出的Marching Boxes(MB)算法结合显示所需精度,对MC算法作了优化,减少了由MC算法生成的三角面片数,使实时观察体数据成为可能。在保留图象细节的前提下MB算法输出的三角面片数比MC算法减少了一半以上,从而加快了体数据的面绘制速度.

Abstract
A widely used isosurlace construction algorithm is called Marching Cubes Algorithm (MC).which produces triangle-represented isosurlace from volume data. The algorithm given in this artic1e solves a problem in MC and gives half-cut triangles in a volume data with no obvious quality deduction. The algorithm is called Marching Boxes Algorithm.
