Three-dimensional measurement is one of the primary interests of various industries such as quality control, documentation of cultural artifacts and medical image processing. In recent years, contrary to the contact-based mechanical methods, active image-based methods using laser light [1] or white light [2] for recovering the surface of the object, have gained considerable attention because of their non-contact nature. Among these techniques, the phase-shifting digital fringe projection (DFP) is well-established due to its advantageous characteristics such as full resolution and high accuracy measurement [3]. Extremely dense point clouds that are obtained from structured light 3D scanners leads to many problems in further processing steps. The processing, modeling and visualizing of huge amount of points is a very hard problem for conventional computers
