Abstract: A method of rendering 3D graphics image includes the steps of: storing the primitives information into the primitive bank and parameter bank whose entries are made up the primitive IDs; converting the primitives into the pages whose coordinates are made up the page IDs; matching incoming page IDs of the incoming primitive with the page IDs stored in the page RAM in such a manner that when the incoming page ID of the incoming primitive matches with the sorted page ID stored in the page RAM, the incoming primitive are added to the corresponding page node in the page RAM under the corresponding page ID; flushing the page RAM when the free page nodes of the page RAM less than a predetermined amount or when the primitive's counter of the page node reaches another predetermined number; and rendering the primitives stored in the page memory into pixels.
