ABSTRACT:
A graphics processing circuit for use in a graphics accelerator that includes a clipping processor, with a vertex input data path operatively connected to a vertex data input of the clipping processor. A clipping preprocessor has a vertex data input operatively connected to the vertex input data path and a control output operatively connected to a control input of the clipping processor. The clipping preprocessor is constructed and arranged to perform an evaluation of a relationship between primitive vertex data from the vertex input data path and a clip region and to provide a signal on the control output based on this evaluation.
