Abstract
Similar, contiguous primitives are stored as a single primitive in zone rendering bins. A primitive packet used in the bin is allowed to vary in length and the currently open type of primitive is recorded on a per-bin basis. A special code is used to specify a variable number of subsequent indices. With this mechanism, the hardware is able to start outputting and replicating primitive commands into bin lists on the fly without requiring the buffering of the entire primitive. Given the variable nature of the primitive instruction, multiple similar/sequential primitives can be concatenated using a single primitive command header.
