Abstract
A method and apparatus for improved concurrency within a video graphics process by generating culling information from geometry information. The geometry information corresponds to an image to be rendered, and the culling information indicates the triangles of the objects of the image that are in a front-facing or back-facing position. Having generated the culling information, set-up information is generated therefrom. The set-up information provides rendering data for the triangles of the object of the image being rendered. Next, pixel data is generated for a triangle based on the set-up information. To improve the concurrency, the queuing and the retrieval of the culling information and the set-up information from non-local memory are controlled such that the generating of the culling information, the set-up information, and the pixel data is done with improved concurrency.
