1. A method for performing anti-aliasing of a first voxel of a three-dimensional image displayed on a plurality of optical elements, wherein a first voxel depth value of the first voxel is between a pair of optical element depth values corresponding to a pair of optical elements bounding the first voxel, the method comprising the steps of: generating a depth adjustment value from the first voxel depth value; adjusting a first color value associated with the first voxel using the depth adjustment value; and displaying a second voxel on at least one of the pair of optical elements using the adjusted color value.
