Re: Planet Generation - Part I
#2I wonder if anyone has generated planets by running a geological simulation - plates, subduction zones, vulcanism, erosion.... etc.

#3Very cool result! I've been wondering about applying the height-maps that you get from Perlin/Simplex directly to the vertices of a planet, for 3D terrain. I'd imagine that the cube mapping approach might not be perfect for this because of the irregular distance between vertices. The geodesic dome would probably work, but I have no idea how you would generate noise for a shape like that.

Dwarf Fortress does.

That would be interesting. I had a quick look and found this paper, they simulate tectonic plate movement for terrain generation:

and this one looks like some sort of terrain generation based on erosion:

Actually, it just occurred to me that what would be really cool would be a geology version of the Star Walk app - you point it at the ground/hill/mountain and it shows you what its made up of.
Explaining the history of features would be even cooler :-)

And imagine if you had a game that generated terrain by erosion + tectonic plate movement, and you got to see a visualisation of that as it was generating :) 2 billion years of geological activity, simulated in a minute-scale.

#10If you search for "fibonacci grid sphere," you'll find the grid used for research. It's less regular and a lot more work, with a few regions of five or seven sides, but it might look more natural, and it's used because it has fewer sharp corners than the icosohedron. Just another option.
