Abstract: In a graphics processing pipeline 1, a primitive depth sorting stage 9 is arranged prior to the rasterization stage 3 and rendering stage 6. The primitive depth sorting stage 9 operates to sort successive sub-sets of primitives in a stream of primitives 2 received by the graphics processing pipeline 1 based on their depth values. The so-sorted primitives are then output from the primitive depth sorting stage 9 in their sorted depth order to the rasterizer 3. This makes the depth test stages 4, 13 of the graphics processing pipeline 1 more efficient in their hidden surface removal operations, because the primitives entering the rasterizer 3 will be in depth order.

Abstract translation: 在图形处理流水线1中，原始深度排序阶段9被布置在光栅化阶段3和渲染阶段6之前。原始深度排序阶段9操作以将基元2的连续子集排列在 图形处理管道1基于其深度值。 然后将经分类的原语从原始深度分类阶段9以其分类深度顺序输出到光栅化器3.这使得图形处理管道1的深度测试阶段4,13在其隐藏的表面去除操作中更有效，因为 进入光栅化器3的图元将是深度顺序的。
