Marc Culler and I pleased to announce version 2.0 of SnapPy, a program for studying the topology and geometry of 3-manifolds. Many of the new features are graphical in nature, so we made a new tutorial video to show them off. Highlights include
- A manifold browser window for easily examining a particular manifold.
- Many improvements to the link editor, including
- A smoothed view mode with image export to EPS/PDF/SVG/TikZ.
- Producing a fully editable link from combinatorial data like a DT code.
- Splitting manifolds along surfaces of non-negative euler characteristic.
- Generalizing the ptolemy obstruction class to allow computation of PGL(3,C)-representations and improving usability of the ptolemy module.
- CensusKnots now includes knot exteriors with 8 tetrahedra.
As always, you can get the new version here.
