I looked here for where I’m going to make my own generator. Nice and simple right off of Stefan Gustavson’s code.
Note: while that thread is excellent, it doesn’t really go over how to use noise for multi-octave fractal implementations like terrain generation.
I’ve responded separately from my other answer to address that specifically… for those who can’t get their hands on the book and would rather not bother with the depth.
Anyway, there are probably better sites but I don’t have them to hand… but the full GPU Gems 3 article is available online:
…that’s essentially what I built my IsoSurface stuff off of.
Skip down to the section: 1.3.2 Generating the Density Values
It walks through building up terrain generation from source noise. The type of noise doesn’t really matter from a perspective of how to use it (whether Perlin, Simplex, other).
