Abstract
Incoming geometry data are buffered in one or more buffers. The data are written to the buffers in an order which is not necessarily the order in which a processor or processors that construct images from the data need the data for fast processing. The data are provided to the processors in the order needed for fast processing. In some embodiments, fast processing involves starting critical path computations early. Examples of critical path computations are lighting computations which take more time than position computations. At least one processor has a pipelined instruction execution unit. The processor executes critical path computation instructions as long as a critical path instruction can be started without causing a pipeline stall. When no critical path instructions can be started without causing a stall, the processor starts a non-critical path instruction.
