1. A method for creating motion blur in a computer-generated scene, the method comprising: receiving a plurality of vertices in a first component of a graphics processing unit (GPU), wherein the plurality of vertices is included in a scene in which motion blur is to be created; displacing each of the plurality of vertices; receiving a primitive that includes at least one of the displaced vertices in a second component of the GPU; transforming the primitive; generating a plurality of primitive samples over a time aperture; and outputting the plurality of primitive samples to further components of the GPU for further processing for display of the scene with motion blur.
