discretegroup
The discretegroup package is a metric-neutral framework for working with the fundamental groups of 2- and 3-dimensional euclidean, hyperbolic, and spherical orbifolds and manifolds, with particular focus on a visualization link to jReality.
New users are encouraged to begin with the tutorial package, which contains a series of stand-alone applications demonstrating the basic and some not-so-basic capabilities of the package.
