Is this possible? If it’s not possible in Unity, are there programs out there that can do this same sort of thing. Manually modelling the surface would be an absolute pain.

Basically everything is possible in Unity, you just have to program it. In this case it would involve Texture2D.GetPixels + Mesh class + math.
