摘要： One embodiment of the present invention sets forth a technique controlling the pixel location at which the plane equation is evaluated. Multiple pixel offsets (dx, dy) may be specified that each define to a sub-pixel sample position. Attributes are then calculated for each sub-pixel sample position that is covered by a geometric primitive. One advantage of the technique is that anti-aliasing quality may be improved since high frequency color components may be selectively supersampled for particular geometric primitives.

摘要： A graphics pipeline rasterizes primitives and generates a stream of groups of pixels, such as a stream of pixel quads. A tile coalesce unit received the stream of groups of pixels and generates pixel tiles for use by downstream pixel processing units. The pixel tiles facilitate hazard checks and transaction coherency.

摘要： A graphics pipeline has at least one stage that determines operations to be performed on graphics data based at least in part on data processing attributes associated with the graphics data. One application is to permit one or more operations in a stage to be bypassed. Another application is a multi-function stage in which the data operations that are performed depend at least in part on the data type.

摘要： One embodiment of the present invention sets forth technique for watertight evaluation of Gregory patches for Catmull-Clark subdivision surfaces. Each boundary of each patch within a subdivision surface is configured to be owned by one related patch. In general, a given patch may own specific control points for the patch, while certain other control points for the patch may need to be reconstructed because the control points are owned by an adjacent patch. For a given patch, each control point along to a shared boundary is consistently generated using reconstruction data available to the patch. The reconstruction data is generated from values associated with a patch that owns the shared boundary. Because numerically identical data is used to evaluate each patch at each boundary, the boundaries are watertight. One advantage of the present invention is that watertight evaluation may be achieved using similar computational effort versus conventional non-watertight evaluation techniques.
摘要翻译：本发明的一个实施方案提出了用于Catmull-Clark细分表面的Gregory贴剂的水密性评估的技术。细分表面内每个贴片的每个边界均被配置为由一个相关的贴片拥有。通常，给定的补丁可以拥有补丁的特定控制点，而补丁的某些其他控制点可能需要重建，因为控制点由相邻补丁拥有。对于给定的补丁，沿着共享边界的每个控制点始终使用修补程序可用的重建数据生成。重建数据由与拥有共享边界的补丁相关联的值生成。因为使用数字相同的数据来评估每个边界上的每个补丁，所以边界是不透水的。本发明的一个优点是可以使用与常规非水密性评估技术相似的计算工作来实现水密性评估。

摘要： Heterogeneous processors can cooperate for distributed processing tasks in a multiprocessor computing system. Each processor is operable in a “compatible” mode, in which all processors within a family accept the same baseline command set and produce identical results upon executing any command in the baseline command set. The processors also have a “native” mode of operation in which the command set and/or results may differ in at least some respects from the baseline command set and results. Heterogeneous processors with a compatible mode defined by reference to the same baseline can be used cooperatively for distributed processing by configuring each processor to operate in the compatible mode.

摘要： A method for providing state inheritance across command lists in a multi-threaded processing environment. The method includes receiving an application program that includes a plurality of parallel threads; generating a command list for each thread of the plurality of parallel threads; causing a first command list associated with a first thread of the plurality of parallel threads to be executed by a processing unit; and causing a second command list associated with a second thread of the plurality of parallel threads to be executed by the processing unit, where the second command list inherits from the first command list state associated with the processing unit.
