quadcube-1.0.0

Base class of all quadcube projections.

Description

Quadrilateralized spherical cube (quad-cube) projections belong to the class of polyhedral projections in which the sphere is projected onto the surface of an enclosing polyhedron.

The six faces of the quad-cube projections are numbered and laid out as:

      0
4 3 2 1 4 3 2
      5
