The segmentation technique of 3D mesh models plays a key role in comprehending and processing digital geometric models. A new segmentation algorithm for 3D mesh models based on conformal factor and k-means clustering is proposed to deal with the existing problems in segmentation methods, which includes a lack of semantic information and low performance in segmentation results. It is easy to obtain an effective segmentation results with semantic information since the conformal factors carry global feature information of the model. Firstly, the discrete Gaussian curvatures of each vertex are figured out. Secondly, the conformal factors are calculated by employing Laplace-Beltrami operators. Finally, the clustering of meshes is realized by modified k-means clustering algorithm. Experimental results show that the proposed algorithm not only can achieve meaningful segmentation of 3D models, but also has good anti-jamming performance caused by pose variation of the model.
