Abstract
We need automatic high–quality freeform surfaces generation algorithm, in order to convert quickly the dense point sets produced by laser scanners into useful geometric models. We use the method of moving least squares(MLS) to make the density of the points constant, and to generate smooth points. Thus we can generate a high–quality freeform surface. In this paper, we present a procedure for generating constant spacing points from a set of scanned 3D points, and evaluate a MLS–surface under various conditions.
