Computergraphiksystem mit leistungsfähiger Vorverarbeitung des Clippings von Primitiven |
摘要 |
A graphics processing circuit for use in a graphics accelerator that includes a clipping processor, with a vertex input data path (129) operatively connected to a vertex data input of the clipping processor. A clipping preprocessor (112) has a vertex data input operatively connected to the vertex input data path and a control output (109, 111) 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. <IMAGE> |
