Abstract
A method and apparatus are provided for rendering a 3 dimensional computer graphics image. The image is subdivided into a plurality of rectangular areas and primitives which may be visible in the image are assigned to respective ones of a plurality of primitive blocks. A determination is made as to which primitive blocks contain primitives which intersect each rectangular area. The rectangular areas are then grouped into a plurality of fixed size groups and control stream data for each of the fixed size groups is derived, this control stream data including data which determines which primitive blocks are required to render the rectangular areas in each respective first fixed size group. The control stream data is then used to render the image for display.
