Abstract: Systems and methods are provided to create better-looking animated eyes for CG characters. The systems and methods set the rigging of each eye to, rather than precisely converge on a target location, converge but be rotationally or angularly offset by a certain amount to simulate correct physical eye positioning and movements. In addition, the systems and methods provide even more realistic eye appearance by taking account of the refractive properties of the cornea, e.g., which can make the pupil appear larger than it actually is. The systems and methods may further take account of a shadowing effect of the upper eye caused by the brow, eyelashes, and upper lid (as well as an effect caused by reflection from the underside of the eyelashes). This darkening of the upper portion of the eye addresses vertical eyeline discrepancies caused by the visual and optical illusion of incorrect lighting.

Abstract: The desire to use an Accelerated Processing Device (APD) for general computation has increased due to the APD's exemplary performance characteristics. However, current systems incur high overhead when dispatching work to the APD because a process cannot be efficiently identified or preempted. The occupying of the APD by a rogue process for arbitrary amounts of time can prevent the effective utilization of the available system capacity and can reduce the processing progress of the system. Embodiments described herein can overcome this deficiency by enabling the system software to pre-empt a process executing on the APD for any reason. The APD provides an interface for initiating such a pre-emption. This interface exposes an urgency of the request which determines whether the process being preempted is allowed a grace period to complete its issued work before being forced off the hardware.
