Abstract
A computer graphics system splits vertex data into first and second streams and stores the streams in separate regions of memory. In a specific embodiment, the first stream includes positional data and the second stream includes non-positional color and texture data. A visibility subsystem uses only the first stream to perform visibility processing, thus reducing bandwidth requirement. The rendering system processes data from subsets, identified by the visibility subsystem, of both streams required to render the visible part of a scene.
