ABSTRACT:
A method of determining neighboring voxels that contribute to a surface of an object includes evaluating a primary voxel that corresponds to a side of a reference voxel. The side of the reference voxel is adjacent to an outside voxel, which is outside the object. The primary voxel is adjacent to the outside voxel and is adjacent to a corresponding secondary voxel. The secondary voxel is age adjacent to a corresponding tertiary voxel. The method also includes determining whether the primary voxel, the secondary voxel or the tertiary voxel is on the same surface as the reference voxel.
