We present an interactive mesh cutting method in this paper, which is based on a formulation of semi-supervised learning. Users first assign foreground and background seed faces on a given triangular mesh by sketch lines. Then the system computes a scalar field across the mesh. After that a coarse segmentation boundary is computed out respect to a specific iso-value, which leads to a refined boundary by tracing the isoline in the scalar field. Our proposed methods are easy for implementing. The

By integrating the proposed mesh cutout tool, we also demonstrate a simple sketch-based mesh editing system. In our system the cutting results can be further deformed, morphed, or cut-and-pasted.
