3D Mesh Model Segmentation Using Marching Plane

Decomposing 3D mesh into meaningful components is a challenging research field in computer graphics. In this paper, we propose a segmentation algorithm which focuses on cutting out individual prominent parts from original mesh based on prominent feature point and marching plane. Our method first extracts prominent feature points which reside on tips of each prominent part of a given mesh. And then the mesh is intersected by a set of planes, namely, marching plane which marches from a prominent feature point. Through the marching process, we extract local cross sections and compute its area which can represent the local volumes. Finally, we can simply cut out the prominent part using marching plane, as the boundary of a prominent part usually lies on the place where the local volume varies rapidly. Experimental result shows our method invariant to the pose, robust to the noise and also competitive when compare to relative works.
