The problem of reconstructing smooth surfaces from discrete data, such as a triangular mesh, is an important practical problem in geometrical design, medical imaging, computer graphics and computer vision. Most approaches attempt to stitch together small polynomial surface patches along their boundaries. We will describe an alternative approach inspired by the overlapping of coordinate charts on a surface, show how to make it practical, and explain its advantages.
