HandleTunnel Software for computing handle and tunnel loops on surfaces

Tamal K DeyKuiyu Li, and Jian Sun


HandleTunnel  software can compute a set of g handle loops and g tunnel loops on a closed surface of genus g. A loop is handle if it wraps around a handle of the surface, a loop is tunnel if it wraps around a tunnel in the complement. See the paper for precise definitions.  The input to the software should be a polygonal mesh (manifold). The detected loops are not oblivious of the geometry--they capture it quite well. The software is based on a recent result described in the  paper given below.  

Codes are  available for  Linux,  and Windows. Please send an email to tamaldey@cse.ohio-state.edu to get the password to access the download area.
