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.

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： 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： The VPC unit and setup unit of a graphics processing subsystem perform culling operations. The VPC unit performs culling operations on geometric primitives falling within a specific criteria, such as having a property within of a numerical range limit. This limit reduces the complexity of the VPC unit. As increasing rendering complexity typically produces a large number of small primitives, the VPC unit culls many primitives despite its limitations. The VPC unit also includes a cache for storing previously processed vertices in their transformed form, along with previously computed culling information. This increases the VPC unit throughput by reducing the number of memory accesses and culling operations to be performed. The setup unit performs culling operations on any general primitive that cannot be culled by the VPC unit. By performing a first series of culling operations in the VPC unit, the processing burden on the setup unit is decreased.
摘要翻译： 图形处理子系统的VPC单元和设置单元执行剔除操作。 VPC单元对属于特定标准的几何图元执行淘汰操作，例如具有数值范围限制内的属性。 这个限制降低了VPC单元的复杂性。 随着渲染复杂度的增加，通常会产生大量的小图元，尽管存在局限性，但是VPC单元剔除了许多图元。 VPC单元还包括用于以先前计算的剔除信息存储先前处理的顶点的转换形式的高速缓存。 这通过减少要执行的存储器访问和剔除操作的数量来增加VPC单元吞吐量。 设置单元对不能被VPC单元剔除的任何一般原语执行剔除操作。 通过在VPC单元中执行第一系列的淘汰操作，降低了设置单元的处理负担。

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.
摘要翻译： 本发明的一个实施例提出了一种控制平面方程被评估的像素位置的技术。 可以指定多个像素偏移（dx，dy），每个像素偏移定义为子像素采样位置。 然后对由几何图元覆盖的每个子像素样本位置计算属性。 该技术的一个优点是可以改善抗混叠质量，因为可以对特定几何基元选择性地超采样高频彩色分量。
