I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the moment I am drawing a cube with VBOs and mapping onto a sphere.
I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement (not that useful in this case I know).
My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this.
Leaving the tiling obvious.
Could anyone advise me on the best route to take?
Any input would be much appreciated.
