System and method for creating motion blur

A graphics processing system configured to create motion blur in a scene, comprising:

• a central processing unit (CPU);
• a memory unit coupled to the CPU;
• at least one programmable graphics processing unit (GPU) coupled to the CPU and to the memory, wherein the at least one GPU comprises:
• a vertex shader, programmable to receive an input vertex that is present in the scene, and to output a displaced vertex before the scene is rendered, the vertex being associated with a first object;
• and
• a geometry shader, programmable to:
• perform geometry amplification of a received primitive having an initial position, and
• generate a plurality of primitive samples by performing operations on the received primitive, wherein a last one of the generated primitive samples has an aperture extent position and wherein each of the remaining generated primitive samples has a position between the initial position and the aperture extent position;
• wherein the performing of geometry amplification and the generating of a plurality of primitive samples are performed before the scene is rendered.

A non-transitory computer-readable medium having stored thereon instructions which, when executed, cause the creation of motion blur in an animated scene, the instructions including:

• receiving a plurality of vertices;
• displacing at least one vertex of the plurality of vertices;
• receiving a primitive defined by at least one of the displaced vertices, the particular primitive having an initial position;
• and
• generating a plurality of primitive samples from the primitive by performing operations on the primitive, wherein a last one of the generated primitive samples has an aperture extent position and wherein each of the remaining generated primitive samples has a position between the initial position and the aperture extent position;
• wherein the receiving of a plurality of vertices, the displacing, the receiving a primitive, and the generating a plurality of primitive samples are all performed prior to rendering of the scene.
