摘要	Meaningful mesh segmentation plays a more and more important role in various graphics applica- tions, such as texture mapping, shape retrieval, and high- quality metamorphosis. This paper proposes a sketch- based interactive framework for real-time mesh segmen- tation. With an easy-to-use tool, the user can freely seg- ment a 3D mesh while needing little e®ort or skill. In order to meaningfully segment the mesh, two dimen- sionless feature sensitive metrics are proposed, which are independent of the model and part size. We show that these metrics give the clear physical meaning to illus- trate discrete di®erential geometric features, such as the curvature tensor and the curve length of gaussian im- age. Finally, we discuss three kinds of boundary smooth- ing methods, and present two fast topology-invariant, geometry-invariant adjustment algorithms based on con- vex hull features and angle features. Compared with pre- vious methods, our method can easily achieve multi-level segmentation in just one session.
