ABSTRACT:
A method of rendering 3-D graphical image data suitable for use in interactive 3-D applications is provided, which reduces the amount of time required to perform the rendering. This is achieved by dynamically adjusting the resolution of the image depending upon the type of operation being performed. 3-D operations are performed at a reduced resolution, while 2-D operations (including display) are performed at full resolution. A method of dynamically enhancing/reducing resolution for image depth information (z-buffer data) is also provided.
