public class OrthographicEquatorial

extends OrthographicOblique

The equatorial case of the Orthographic projection. This is a simplification of the oblique case for MapProjection.latitudeOfOrigin == 0.0. Only the spherical form is given here.

To Do:

this code is identical to the oblique except for 6 lines. It could be moved to the oblique with an isEquatorial flag.
