I want to print each part in a different colour such that no 2 adjacent parts share the same colour.
On a flat plane like a (geographic) map this is possible with 4 colours no matter how complex the map.
Does anyone know of software that can determine this for a multipart 3d print?
I literally just spent an hour digitally colouring parts in blender and I know it needs fewer colours than I used but I can’t figure out how many fewer.
I am afraid I will either find a simple program proving my incompetence at internet search, or some mathematics foundation offering a prize for a solution, again proving my incompetence at internet search.
edit This is a multipart 3d model (e.g. a car or robot), not a painting.
Have you considered trying hueforge for your map rendering? It’s mainly used for rendering photos for 3d color printing, but the principle remains the same for geographical maps rendering. I haven’t rendered a map yet, though I’ve been considering doing it at some point in time, but I’ve been printing 3d color photos with hueforge for quite some time and have been really satisfied with the outcome.
Sorry I forgot that I need to be ultra specific. This is for a 3d model not a flat image. And it’s not a flexydragon (which could be treated as a flat image since each part connects to 2 others only).
In hueforge you can establish the depth size of your sections (per color) and thus increase the print height to the size you need. Again, just a suggestion, as I haven’t tried it yet but have considered it feasible… at least to a certain extent.
