Abstract
An apparatus and method allows efficient processing of vertex data received in any suitable format. The method and apparatus accesses stored vertex data that may be stored in a plurality of different formats. A single copy of the received vertex data is stored in memory so that the system does not require a block of memory containing differing formats of the vertex data. The apparatus and method utilizes a universal vertex data fetching mechanism which controls retrieval of vertex data stored in the first format in memory based on multi-format description data. As such, the vertex data that may be received in one of a plurality of formats, is effectively coded so that a data fetcher may appropriately fetch vertex parameter data from suitable addresses independent of the format in which the vertex data was received.
