The ZipPack Polygon Mesh Zippering Package (Zipper) is a program for combining range images into a polygonal mesh. It was specifically created to more fully use range images acquired from a Cyberware range scanner. With appropriate file conversion, however, there is nothing preventing the use of zipper with range images taken with other scanners.
The zipper program and its source code are available for research and commercial use, free of charge, as described at the software website. The software was written by Greg Turk.
The research results from the "zipper" program are described in the article:
