ABSTRACT:
A computer graphics system for rendering graphics primitives based upon primitive data received from a host computer through a graphics interface. The primitive data may include vertex state and property state values. The computer graphics system includes a plurality of geometry accelerators configured to process the primitive data to render graphics primitives. The graphics primitives are rendered from one or more vertex states in accordance with the property states currently maintained in the rendering geometry accelerator. A distributor divides the primitive data into chunks of primitive data and distributes each of the primitive data chunks to a current geometry accelerator recipient. In one aspect of the invention, the distributor includes a state controller interposed between the host computer and said plurality of geometry accelerators. The state controller is configured to store and resend selected primitive data to the plurality of geometry accelerators based upon whether the one or more vertices of a graphics primitive are contained in more than one of the chunks of primitive data. A driver, based upon the occurrence of function calls that cause certain dependent property states to have values determined by the value assigned to a determining property state, controls the state controller to provide values of the determining property state to the geometry accelerators for values of said deponent property states.
