Complicated tool to create dithered images with limited palette of colors using tetrahedrization of the colorspace.
Its intended use is to create minecraft map-art.
An implementation of this algorithm in a Minecraft mod might be a good idea in the future.
Simply run minecraftColors.pyto generate an image. To change the source image, and target resolution, you have to edit line 192 of this file.
By default the pallette correspond to the all the available colors for Minecraft map-art.
Tetrahedrization-related code is in unay.py.
