Abstract
A method in accordance with the invention comprises the step of providing a) pixel array and a computer model of a geometric surface, and b) providing a second array (a Z array) containing information concerning the 3D characteristics of the structure depicted in the pixel array. The Z array is used to modify the location of the geometric surface. The pixel array and modified geometric surface are then used to render an image that can be displayed on a CRT or other output device. By modifying the geometric surface model in this way, it is possible to create more realistic images.
