Random world generation with fractal terrain

Short video demonstrating the stages of creating a random world. After creating a random fractal height-map, temperature bands are generated, wind and rain is simulated (including realistic "rain shadows" caused by mountains) and rivers flow.

Or do a Google search for "Hero Extant" to keep up to date on the computer game that I am creating based on this technique.

This blows Minecraft's terrain system out of the water.

@theblackside1000 You would want 3D Simplex Noise. Obviously this vastly increases the memory requirements over 2D data.

What about caves

@Longor1996 Well, that's true now, but I posted the comment before the release of 1.8. I really like the direction the game is evolving in.

@jarblewarble Nope! In Minecraft 1.8 the Terrain Generation is based also on Fractals! (And Biome)

I'm really impressed - shame I didn't find this before I pulled all my hair out trying to use Fractal Mapper though!

This is very cool. Great job! Thanks for making a great tool.
