Tangentially related to Minecraft, cause that’s the place where I need to implement it.
The gist is, i’m making a custom dimension that has some preset terrain.
My first thought was to do it via the heightmap I have, but the terrain itself is HUGE therefore the mod would be +1GB due to the segmented high quality heightmap images.

Now my question is: Is there a feasible way of grabbing my heightmap and transform it into a noise function, or otherwise use the terrain noise generators available in minecraft to exclusively programatically generate the SAME terrain of the heightmap? Esentially doing the inverse of what its usually done, not from noise->terrain/height data, but height data-> terrain
