Patent number: 6778176Abstract: A method, apparatus and article of manufacture are provided for sequencing graphics processing in a transform or lighting operation. A plurality of mode bits are first received which are indicative of the status of a plurality of modes of process operations. A plurality of addresses are then identified in memory based on the mode bits. Such addresses are then accessed in the memory for retrieving code segments which each are adapted to carry out the process operations in accordance with the status of the modes. The code segments are subsequently executed within a transform or lighting module for processing vertex data.Type: GrantFiled: June 21, 2002Date of Patent: August 17, 2004Assignee: Nvidia CorporationInventors: John Erik Lindholm, Simon Moy, Kevin Dawallu, John Montrym
