An example of a 3D image that has been rendered with the reported low-resolution technique as described herein is shown in FIG. 20 . At the center of the cube, there are 4 high-resolution 3D model points labeled P1-P4, where P1 is located above the second vertex and P4 below the first vertex. For a view of the model, there are 2 views that demonstrate the model's effect in the orthographic view. In the first view, the model is rendered as a wall, which is denoted by the green block;
