Coordinate systems are presented for fast 3-D transformations of complex surfaces, such as the depth maps produced by a laser camera or by a viewing algorithm. It is shown that these coordinate systems are natural for calculation on depth maps and correspond to a differential geometry approach of the problem. We describe algorithms using these coordinate systems to realize perspective to perspective and parallel to parallel view transformations. These parallel algorithms can be implemented using 1-D transformations only.
