摘要： Structure (FIG.12) and method for performing conservative hidden surface removal in a graphics processor. Culling (9000) is divided into two steps, a magnitude comparison content addressable memory cull operation (MCCAM Cull) (9002), and a subpixel cull operation. The MCCAM Cull discards primitives that are hidden completely by previously processed geometry. The Subpixel Cull takes the remaining primitives (which are partly or entirely visible), and determines the visible fragments. Performing hidden surface removal includes: selecting a current primitive comprising a plurality of stamps; comparing stamps to stamps from previously evaluated primitives; selecting a first stamp as a currently potentially visible stamp (CPVS) based on the depth of current and previous stamps; comparing the CPVS to a second stamp; discarding the second stamp when it would not affect a final graphics display image; making the second stamp the CPVS, when it hides the CPVS and when both the second stamp and the CPVS are at least partially visible; and dispatching both when their visibility depends on parameters evaluated later in the graphics pipeline.

摘要： The present invention is a mid-pipeline sorting unit that sorts image data mid-pipeline in a tiled 3-D graphics pipeline architecture. The image data includes vertices of geometric primitives. The mid-pipeline sorting determines whether a geometric primitive intersects a region of a 2-D window. The 2-D window having been divided into multiple such regions. Upon determining which region of the 2-D window that the geometric primitive intersects, the mid-pipeline sorting unit stores the vertices that define the geometric primitive into a memory in a manner that associates each of the geometric primitive's vertices with the region that was intersected. After the image data is sorted into the memory, the mid pipeline sorting unit sends the sorted image data to the subsequent stage on a region by region basis. Yet another embodiment of the present invention provides a guaranteed conservative memory estimate to the mid-pipeline sorting stage of whether there is enough free memory for the mid pipeline sorting unit to sort and store the image data. Yet another embodiment of the present invention sends image data from a memory to a next stage in a graphics pipeline in a spatially staggered sequence.
摘要翻译：本发明是一种中间流水线分拣单元，其以平铺的3-D图形流水线架构中间管线分类图像数据。图像数据包括几何图元的顶点。中间流水线排序确定几何图元是否与2-D窗口的区域相交。 2-D窗口已分为多个这样的区域。在确定几何图元相交的2-D窗口的哪个区域时，中间流水线分类单元以将每个几何图元的顶点与相交的区域相关联的方式将定义几何基元的顶点存储到存储器中。在将图像数据分类到存储器中之后，中间流水线分拣单元在逐个区域的基础上将排序的图像数据发送到后续的阶段。本发明的另一个实施例提供了对中间流水线分类阶段的保证的保守的存储器估计是否存在足够的空闲存储器，用于中间管道分类单元对图像数据进行分类和存储。本发明的另一个实施例将图像数据从空间交错序列的图形管线中的存储器发送到下一级。
