Abstract: A fast 3D mesh segmentation method was introduced. Different from most of the others, the method provided segmentations in respect of the mesh face set, and the curvatures were estimated between two adjacent faces. Based on watersheds algorithm, the method completes the segmentation using interactive markers as indicators, thus over-segmentation and noising problems were avoided. At the same time minima rule was adopted to achieve a much reasonable result according to human's subjective perception. Experimental results show that the process is fast enough for interactive applications.
