Abstract:
One embodiment of the present invention sets forth a technique for reducing the overhead for transmitting explicit begin and explicit end commands that are needed in primitive draw command sequences. A draw method includes a header to specify an implicit begin command, an implicit end command, and instancing information for a primitive draw command sequence. The header is followed by a packet including one or more data words (dwords) that each specify a primitive topology, starting offset into a vertex or index buffer, and vertex or index count. Only a single clock cycle is consumed to transmit and process the header. The performance of graphics application programs that have many small batches of geometry (as is typical of many workstation applications) may be improved since the overhead of transmitting and processing the explicit begin and explicit end draw commands is reduced.
