Abstract
A token-based buffer system for a geometry pipeline in three-dimensional graphics comprises: a buffer control initialization (BCI) unit, a new token or index module, a geometry control pipeline, a vertex buffer, and a processing engine. The token-based buffer system provides a shared resource environment in which tokens are assigned for blocks of data. Each block of data includes that data necessary for each unit or stage in the geometry pipeline to perform its computation. The use of tokens is advantageous because it optimizes the storage efficiency for storing the blocks of data and ensures the correctness of the data as it is passed between stages.
