Algorithms for generating improved images of curved surfaces by distributing errors along Hilbert's curve (Q1109500)

Several algorithms for generating curved surfaces are presented, in which the difference between the sum of displayed intensities and the sum of computed intensities is distributed to the next pixel along a Hilbert curve. This method improves the smoothness of images by reducing the Mach Band effect, which is related to a sudden change of intensities. A Hilbert path is found by recursively subdividing the image space.
