The model was preprocessed to assure the regulation of facets, create the dual graph of it, and then adapt Reeb Graph to extract the skeleton which contains enough information of the model, such as gesture and topological features, to be able to be used as descriptor of 3D model retrieval.

通过对模型进行一定的预处理保证面片的规则，定义面片间距离计算方法，创建模型的对偶图，识别连通分量，在连通分量上应用Reeb图的计算思想抽取原模型的骨架。试验表明，该算法具有较好的计算效果和效率，最终的骨架保存了模型的拓扑连通性以及姿态，可用于基于内容的三维模型检索时的特征描述符。
