Abstract: A primitive listing and sorting arrangement for a tile-based graphics rendering system in which primitive lists can be prepared for at least two different sets of sub-regions of the render target area. Two or more alternative solutions for listing the primitive for rendering using the sub-regions of at least two of the at least two different sets of sub-regions of the render target area that primitive lists can be prepared for are determined (S62). A cost function is then used to assess the cost of listing the primitive for each determined alternative primitive listing solution (S63) and the primitive listing arrangement to use is then selected based on the cost assessment (S64). Embodiments use an adaptive cost function that can be modified in use based on analysis of the costs for the primitive listing process actually being experienced in use.

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.
