class TGLOrthoCamera: public TGLCamera


TGLOrthoCamera

Orthographic projection camera. Currently limited to three types
defined at construction time - kXOY, kXOZ, kZOY - where this refers
to the viewport plane axis - e.g. kXOY has X axis horizontal, Y
vertical - i.e. looking down Z axis with Y vertical.

The plane types restriction could easily be removed to supported
arbitary ortho projections along any axis/orientation with free
rotations about them.
