Provides functions to construct various simplicial complexes.
Generate a minimal triangulation of the surface of a cylinder without ends
Generate a minimal triangulation of dunce hat.
generate a minimal triangulation of the surface of a Klein bottle.
create a simplicial complex containing a line.
Generate a minimal triangulation of the surface of a Moebius band. A one sided surface with a single external boundary line.
Generate a minimal triangulation of the surface of a projective plane. A one sided surface which cannot be embedded in 3D space without intersecting itself. There are no external boundaries, every edge connects two faces. (A punctured projective plane is equivalent to a Moebius band)
Generate a simplicial complex equivalent to a solid hyper-sphere. That is, a solid volume with no holes in it, so we use a single n-dimensional simplex.
Generate a simplicial complex equivalent to the surface of a hyper-sphere. That is, the surface of a volume with no holes in it, so we use a minimal triangulation of the faces of a single simplex.
generate a minimal triangulation of the surface of a 3-dimensional torus.
