ABSTRACT:
A computer system which exhibits increased performance for stereo viewing. The computer system includes a display screen, a bus for transferring data, a memory coupled to the bus for storing geometric primitives and left and right view transformation matrices. Furthermore, the computer system includes a processor coupled to the bus, wherein the processor is configured to enable stereo mode and to execute an application for rendering objects on the display screen in the stereo mode. The computer system also includes a graphics accelerator coupled to the bus. The graphics accelerator includes a buffer for storing a received geometric primitive to be rendered in stereo mode, as well as memory for storing the left and right view transformation matrices. The graphics accelerator also includes a transformation unit which is configured to generate a first transformed geometric primitive in response to the received geometric primitive and the left view transformation matrices. The transformation unit is configured to subsequently generate a second transformed geometric primitive in response to the received geometric primitive and the right view transformation matrices. The received geometric primitive is maintained in the buffer subsequent to generation of the first transformed geometric primitive at least until accessed by said transformation unit during generation of second transformed geometric primitive.
