v3.2 Latest

Latest

An alternative implementation of the length spectrum. It supports verified computations and is significantly faster in some cases.
isometry_signature now also works for closed manifolds.
A paper plane or eye ball in the inside_view showing the position and bearing of the user in the hyperbolic manifold.
A faster and more robust algorithm to the compute maximal cusp area matrix.
Bug fix to slice_obstruction_HKL: earlier versions incorrectly allowed looking at mod 2 homology of the branched cover, where the theory does not directly apply.
New self-contained SnapPy application for Linux.
Support for Python 3.13 and SageMath 10.5.

v3.1

A method snappy.Manifold.exterior_to_link for going from a link exterior to a link diagram taken from Dunfield-Obeidin-Rudd.
Covers now computed by the stand-alone low_index module, which uses multiple processor cores and is typically much faster than the old code. In some cases, it is dramatically faster than even GAP or Magma.
Added geodesics to the inside_view.
Added drilling any simple geodesic with snappy.Manifold.drill_word and snappy.Manifold.drill_words, not just those that are combinatorially simple (snappy.Manifold.dual_curves).
Support for Python 3.11 and SageMath 10.0.
Modernized styling of the documentation.
