COMBINING THREE-DIMENSIONAL SURFACES

摘要

A method for mapping, including measuring coordinates of a first set of points on a first surface of a first portion of a three-dimensional (3D) element and generating a first volume enclosed by the first set of points. The method also includes measuring coordinates of a second set of points on a second surface of a second portion of the 3D element and generating a second volume enclosed by the second set of points. The method continues by connecting the first and second volumes to form a combined volume, and generating coordinates of a third set of points on a third surface of the combined volume to form a 3D surface map of the element.
