三角网格分割是数字几何处理的重要问题之一，从分割驱动信号、分割类型、分割策略、算法复杂度、适用范围等方面对典型的网格分割算法如迭代聚类法、区域生长算法、分水岭算法、层次分解或合并法、谱分析法、骨架方法等进行了详细的比较和论述。并结合实际工作，对网格分割的研究趋势进行了展望。

Mesh segmentation is one of the important geometry processing problems. In this paper, with attention to geometry signal for segmentation, segmentation type, algorithm principle, algorithm efficiency, we survey those typical mesh segmentation techniques such as clustering method, region growing method, watershed-based method, hierarchical clustering or decomposition method, spectral analysis method, skeleton-based method. Combining with our work, the tendency of this research direction is further discussed.
