Claim 12:
13. A system for rendering 3D graphics, comprising:
one or more processors and non-transitory memory allocated to form:
a 3D motion vector module configured to receive a 3D model from a game engine and configured to output a plurality of 1-phase 3D motion vectors (3D MV1s) and a plurality of 0-phase 3D motion vectors (3D MV0s) based on the 3D model, each 3D MV1 comprising a change in a vertical position, a change in a horizontal position, and a change in a depth position of an object at a respective pixel from a current frame to a previous frame, each MV0 comprising a change in a vertical position, a change in a horizontal position, and a change in a depth position of an object at a respective pixel from the previous frame to the current frame; and
a block motion vector module configured to generate a 2.5D block MV1 texture and a 2.5D block MV0 texture from the plurality of 3D MV1s and the plurality of 3D MV0s, respectively, and output the 2.5D block MV1 texture and the 2.5D block MV0 texture for image processing in order to form an image to be displayed on a display, wherein the 2.5D block MV1 texture comprises a plurality of MV1 blocks each formed from a respective subset of the plurality of 3D MV1s, and wherein the 2.5D block MV0 texture comprises a plurality of MV0 blocks each formed from a respective subset of the plurality of 3D MV0s.
