Abstract

Given a finite point set in R3 scanned by special devices from the object surface, a surface model interpolating or approximating the points set has to be obtained. We use for the reconstruction a CRUST algorithm by Nina Amenta, which selects surface triangles from the Delaunay tetrahedronization using information from the dual Voronoi diagram. This set of candidate surface triangles does not form a manifold, so the manifold extraction step is necessary. We present two improvements for this step, the former is limited to the used algorithm and the latter can be used with any other reconstruction algorithm.
