Draw commands with built-in begin/end

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, process a sequence of primitive draw commands, by performing the steps of:

• determining that the sequence of primitive draw commands includes an implicit begin command and an implicit end command;
• extracting a primitive topology, a first index buffer parameter, and an index count parameter corresponding to a primitive from the sequence of primitive draw commands;
• reading a set of indices corresponding to the primitive from locations in an index buffer based on the first index buffer parameter and the index count parameter;
• and
• initiating rendering of the primitive using vertex data associated with the set of indices.

A system for processing a sequence of primitive draw commands, the system comprising:

• a parallel processing unit comprising a front end configured to:
• determine that the sequence of primitive draw commands includes an implicit begin command and an implicit end command;
• extract a primitive topology, a first index buffer parameter, and an index count parameter corresponding to a primitive from the sequence of primitive draw commands;
• read a set of indices corresponding to the primitive from locations in an index buffer based on the first index buffer parameter and the index count parameter;
• and
• initiate rendering of the primitive using vertex data associated with the set of indices.
