摘要： In position-only shading, two geometry pipes exist, a trimmed down version called the Cull Pipe and a full version called the Replay Pipe. Thus, the Cull Pipe executes the position shaders in parallel with the main application, but typically generates the critical results much faster as it fetches and shades only the position attribute of the vertices and avoids the rasterization as well as the rendering of pixels for the frame buffer. Furthermore, the Cull Pipe uses these critical results to compute visibility information for all the triangles whether they are culled or not. On the other hand, the Replay Pipe consumes the visibility information to skip the culled triangles and shades only the visible triangles that are finally passed to the rasterization phase. Together the two pipes can hide the long cull runs of discarded triangles and can complete the work faster in some embodiments.
摘要翻译： 在仅位置阴影中，存在两个几何管道，一个称为Cull管道的修剪版本以及称为Replay Pipe的完整版本。 因此，Cull管道与主应用程序并行执行位置着色器，但是通常会生成关键结果的速度要快得多，因为它仅获取和仅阴影顶点的位置属性，并避免光栅化以及帧的像素渲染 缓冲。 此外，Cull管道使用这些关键结果来计算所有三角形的可见性信息，无论它们是否被淘汰。 另一方面，重放管道消耗可见性信息来跳过被剔除的三角形，并仅遮蔽最终传递到光栅化阶段的可见三角形。 两个管道一起可以隐藏丢弃的三角形的长的剔除运行，并且在一些实施例中可以更快地完成工作。

摘要： In one embodiment, efficiency of a pixel merge unit of a graphics pipeline is increased by identifying a silhouette edge of an input primitive and bypassing the pixel merge unit for fragments associated with the silhouette edge. Identifying partially covered fragments along the silhouette edge and preventing those fragments from entering the pixel merge unit allows existing fragments within the pixel merge unit to reside within the pixel merge unit for a longer period before getting evicted. The additional residency grants fragments additional time to wait for neighboring fragments to arrive, which, in turn, increases the merge rate for fragments that are eligible to be merged.

摘要： A per-tile test in the 5D rasterizer outputs intervals for both lens parameters, (u,v), and for time, t, as well as for depth z. These intervals are conservative bounds for the current tile for 1) the visible lens region, 2) the time the triangle overlaps the tile, and 3) the depth range for the triangle inside the tile.

摘要： Techniques are described that can delay or even prevent use of memory to store triangles associated with tiles as well as processing resources associated with vertex shading and binning triangles. The techniques can also provide better load balancing among a set of cores, and hence provide better performance. A bounding volume is generated to represent a geometry group. Culling takes place to determine whether a geometry group is to have triangles rendered. Vertex shading and association of triangles with tiles can be performed across multiple cores in parallel. Processing resources are allocated for rasterizing tiles whose triangles have been vertex shaded and binned over tiles whose triangles have yet to be vertex shaded and binned. Rasterization of triangles of different tiles can be performed by multiple cores in parallel.

摘要： First, the colors are partitioned within a tile into distinct groups, such that the variation of color within each group is lowered. Second, each group can be encoded in an efficient manner. The algorithm described herein may give a higher compression ratio than previous algorithms, and therefore may further reduce memory bandwidth at a very low increase in computational cost in some embodiments. The algorithm may be added to a system with existing buffer compression algorithms, handling additional tiles that the existing algorithm fails to compress, thereby increasing the overall compression rate.

摘要： Depth of field may be rasterized by culling half-space regions on a lens from which a triangle to be rendered is not visible. Then, inside tests are only performed on the remaining unculled half-space regions. Separating planes between the triangle to be rendered and the tile being processed can be used to define the half-space regions.
