Detailed Description

The DtOverlayRenderer implements the overlay concept.

An overlay is a 2D scene that is drawn on top of a 3D scene. The 2D scene can contain any number of the 2D primitives which include: DtLineSegment, DtQuad, DtFilledPolygon and DtOutlinedPolygon. The DtOverlayRendered does the actual drawing of the graphical primitives.
