Last time I did dithering was for Polyjet 3D printers. The problem is substantially different from what’s in the article. The palette is fixed, as the colors are physically different materials. The amount of data is huge, an image is a layer and the complete model has thousands of layers, because 3D. I implemented a 3D-generalization of ordered dithering https://en.wikipedia.org/wiki/Ordered_dithering https://en.wikipedia.org/wiki/Ordered_dithering The algorithm doesn’t have any data dependencies across voxels, the result only depends on source data, and position of the voxel. I did it on GPU with HLSL shaders, it takes a few seconds to produce thousands of images.
