This work is alternative approach to the problem of voxel model compression. Originally, Dithering has been developed for colour reduction in two dimensional pictures. Dithering as a compression method is a problem, which we can use as for two dimensional pictures as for three dimensional voxel models. This process I will name 2D-Dithering. First step of decompression is decoding compressed data with used lossless compression method.
Last step is reconstruction of dithered picture.
This process I will name 2D-UnDithering. For a 2D-Dithering I used Floyd Steinberg Dithering, but it is possible to make some experiments with Ordered Dithering or similar method. If original voxel intensity is and dithered voxel intensity of the same voxel is , we can defined, that . On the image is the one possibility of distribution of this error information. But almost m and n are odd integers.
