SYSTEM AND METHOD FOR APPROXIMATING AN EDITABLE SURFACE

摘要

A system for approximating an editable surface from a 3D point set (200) to determine a best-fit plane for the point set (210); ii) project the point set on to the best-fit plane (216), determine a boundary for the best-fit plane according to the point set (218), project a grid on to the best- fit plane within the boundary, the grid containing a plurality of grid points (220), initialize the grid points to zero (222), determine a value for the grid points (224), refine the value for at least a portion of the grid points (226), select at least a portion of the grid points based on one of the value and the refined value and image the editable surface using the selected grid points (240), the editable surface representing a best-fit approximation of the point set to the editable surface
