Abstract: A graphics processing system includes a graphics processor and a memory for storing data to be used by and generated by the graphics processor. In a first rendering pass, the graphics processor generates an array of graphics data and stores the generated array of graphics data in the memory. The array of graphics data generated in the first rendering pass is used in a subsequent rendering pass. In the first rendering pass, the graphics processor determines one or more regions of the array of graphics data that have a particular characteristic, and generates information indicative of the one or more regions. In the subsequent rendering pass, the graphics processor uses the information indicative of the one or more regions to control the reading of the array of graphics data when it is to be used in the subsequent rendering pass.

Abstract translation: 图形处理系统包括图形处理器和用于存储要由图形处理器使用并由其生成的数据的存储器。 在第一渲染过程中，图形处理器生成图形数据阵列并将生成的图形数据阵列存储在存储器中。 在第一次呈现遍历中生成的图形数据阵列用于后续渲染过程。 在第一渲染过程中，图形处理器确定具有特定特征的图形数据阵列的一个或多个区域，并产生指示一个或多个区域的信息。 在随后的渲染过程中，图形处理器使用指示一个或多个区域的信息来控制在后续渲染过程中使用时对图形数据阵列的读取。

Abstract: A set of primitives is divided into plural sub-sets of primitives, and a tree representation for representing the set of primitives in which each leaf node of the tree represents one of the sub-sets, and each parent node of the tree represents a sub-set of primitives corresponding to the combination of the sub-sets of primitives of all of its child nodes, is generated. For each node of the tree representation data indicating: the sub-set of primitives that the node represents; the vertices that are used by the primitives in the sub-set of primitives that the node represents; and the volume of space that the sub-set of primitives that the node represents falls within, is determined. The tree representation is then used to determine a set of primitives and a set of vertices to be processed when processing the set of primitives for the output frame.

Abstract translation: 一组原语被分成多个原语子集，以及用于表示一组原语的树表示，其中树的每个叶节点表示子集之一，并且树的每个父节点表示子 生成与其所有子节点的原语的子集的组合相对应的原语集合。 对于树的每个节点表示数据，指示：节点表示的基元的子集; 由节点代表的图元子集中的原语使用的顶点; 并且确定节点所代表的基元子集落在其中的空间量。 然后，树表示用于确定在处理输出帧的图元集合时将要处理的一组基元和一组顶点。
