Abstract

Based on Delaunay triangulation, point clouds from laser-scanning, computer vision, procedural modeling are input and organized into multi-resolution alpha-shape series. An algorithm for examining singular points on the alpha-shape is proposed on the basis of the tetrahedral facet-adjacency connection from the Delaunay. A final iterative singular point reduction is performed to guarantee the 2-manifold of the alpha-shape, which generates 3D printable models.
