The invention relates to image decomposition strategies and computer-based methods for implementing them. In one method of the invention, the ordering of tetrahedral shapes that define or approximate an image is performed in such a way that neighboring tetrahedral shapes can be identified, located and efficiently used. In one aspect, a binary location code array is used to represent an image and the method for identifying the neighbor shape employs a bit manipulation step in code or pseudo-code for operating a computer. In this aspect, the invention allows one to move between adjacent tetrahedra, and any data corresponding to the tetrahedra, in constant time. |
