Usage: gtscheck [OPTION] < FILE Checks that a surface defines a closed, orientable non self-intersecting manifold. If the surface is self-intersecting, the set of intersected faces is written on standard output as a GTS surface file. -v --verbose print statistics about the surface -h --help display this help and exit The return status reflects the error encountered: 0: none 1: the input file is not a valid GTS file 2: the surface is not an orientable manifold 3: the surface is an orientable manifold but is self-intersecting Reports bugs to popinet@users.sourceforge.net
