  1. SnapPy SnapPy Public

    SnapPy is a package for studying the topology and geometry of 3-manifolds, with a focus on hyperbolic structures. It is based on the SnapPea kernel written by Jeff Weeks.

    C 124 44

  2. Spherogram Spherogram Public

    Spherogram is a Python module for dealing with the kind of planar diagrams that arise in 3-dimensional topology, such as link and Heegaard diagrams. It a component of the larger SnapPy project.

    Python 28 13

  3. PLink PLink Public

    Plink is used to draw link projections and create data structures which describe the projections.

    Python 11 7
