摘要： Systems and methods are provided for controlling texture sampling in connection with computer graphics in a computer system. In various embodiments, improved mechanisms for controlling texture sampling are provided that enable 3-D accelerator hardware to greatly increase the level of realism in rendering, including improved mechanisms for (1) motion blur; (2) generating anisotropic surface reflections (3) generating surface self-shadowing (4) ray-cast volumetric sampling (4) self-shadowed volumetric rendering and (5) self-shadowed volumetric ray-casting. In supplementing existing texture sampling techniques, parameters for texture sampling may be replaced and/or modified.

摘要： Methods, systems, and computer-storage media for target independent rasterization of an image. The target is the memory allocated for a rendered image within a graphics pipeline. Embodiments of the present invention allow the rasterization process's sampling rate to be specified independently from the memory allocated for the rendered image. Embodiments of the present invention also allow the rasterization process to be executed at a rate that does not correspond to the memory allocated for the rendered target.
