摘　　要： 为了提高模型编辑的速度和准确性,提出了一种基于局部历史的拓扑面命名和辨识方法。该方法采用了拓扑面变化的动态命名机制,将建模中复杂的拓扑结构变化过程记录在相应的面编码之中;同时,给出了拓扑面演化的动态编码算法来描述面的相交与合并。根据拓扑面的编码可以辨识该面所属的原始特征以及该面演化的过程,从而解决了拓扑面辨识问题。实验结果表明,该方法能够有效地维护拓扑面编码的一致性。 In order to improve speed and accuracy of model editing, this paper proposed a method of naming and identifying topological faces based on local history. This method adopted dynamic naming mechanism of topological faces＇ changes. It recorded the complex process of topological structure＇ s changes in modeling process into corresponding face codes. At the same time, this paper gave a dynamic encoding algorithm of topological faces＇ evolution in order to describe faces＇ intersection and mergence. According to face＇ s code, this method identified original feature which a face belonged to and its evolution process. The purpose is to solve the problem of face＇ s identification. Experimental results show that this method can effectively maintain the consistency of topological face encoding.
