Mesh segmentation has become an important step in model understanding and can be used as a useful tool for different applications, for instance, modeling and reverse engineering. We present mesh segmentation technique based on an application of the platonic solids. Normal vectors of all faces of the selected platonic solid are defined as the direction vectors. Our algorithm subdivides a triangular mesh into sub-meshes with the comparable direction of the triangle's normals. The smallest angle between the triangle's normal vector and the vector of the platonic solid is a criterion for assigning a triangle to the sub-mesh. Each sub-mesh (segment) can be used for local mesh denoising and remeshing for decreasing the computational time. Initial model features may be restored during the denoising process. Results of experiments on real 3-D models demonstrate the performance and efficiency of the proposed algorithm.
