Abstract
A 3D surface is defined in terms of a set of vertices. The 3D surface and a pixel array are used to generate a 3D image. Portions of the 3D surface are selectively removed using selected criteria. In one embodiment, the 3D surface is defined in terms of a set of triangles, and the triangles are tested for compliance with selected conditions. For example, the triangles can be tested to determine their slope. Based on these tests, the triangles are excised from the geometric surface. In one embodiment, the selected conditions are based on a combination of the slope of the triangles and the color of the pixels bound to the triangles.
