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。
