Abstract
In this paper, we first develop a centroidal Voronoi tessellation (CVT) based surface segmentation algorithm using eigenfunctions of the Secondary Laplace operator (SLO). We then present a novel automatic polycube construction algorithm based on a generalized harmonic boundary-enhanced CVT (gHBECVT) by including the curve-skeleton information. Based on the constructed polycube, we generate quality all-hexahedral meshes in both parametric and physical domains through the parametric mapping. Several examples are presented in this paper to show the robustness of our algorithms.
