COMPUTER GRAPHICS SYSTEM AND METHOD FOR RENDERING AN IMAGE FOR DISPLAY

摘要

The invention relates to a computer graphics systems and a method for rendering an image for display using texture mapping. A combination of the advantages of 3D mipmapping and 4D mipmapping is achieved according to the invention by: storing texture maps in 3D mipmap format, reconstructing at least part of a 4D mipmap from said 3D mipmap on-the-fly, and mapping texture data from said 4D mipmap to corresponding pixel data defining said display image.
