1. A graphics processing unit (GPU) that facilitates bi-directional morphing of two-dimensional (2D) screen-space projections, the GPU comprising: a graphics processor configured to process computer graphics; a memory configured to operate with the graphics processor; the graphics processor further configured to: produce a 2D screen-space projection of a first frame using full three-dimensional (3D) rendering, wherein the 2D screen-space projection of the first frame includes projections of primitives rendered from a 3D model associated with the first frame; produce a 2D screen-space projection of a second frame using full 3D rendering, wherein the 2D screen-space projection of the second frame includes projections of primitives rendered from a 3D model associated with the second frame; morph a 2D screen-space projection of one or more intermediate frames based, at least in part, on color attributes associated with 2D screen-space projections of the primitives of both the first and the second frames; display the first frame, the one or more intermediate frames, and the second frame in that order.
