摘要 使用D2方法计算形体分布[1]算法时采用欧几里德距离计算,欧几里德距离是拓扑无关的。这里我们讨论一种使用测地距离来表示两点距离[21～24]。这种测地距离方法能表达出模型的拓扑关系,它和采用欧几里德距离可能各有不同的应用。 It is non-topology to shape matching by Eula distance.Here,we discuss another way which is geodesic distance.The geodesic distance way can give expression to Topology relation of model,they will have a various of application between both ways.
