I'm wondering if there's a canonical example of translating a non-continuous noise amplitude function (let's ignore anti-aliasing for now) into a normal in a GLSL shader? I've kludged mine to work for now, but I don't think it's best practice to do it the way I am.
I don't know if I'd call it "canonical", but I think the Nvidia Cg book has a method to convert height field images into normal maps, which at least sounds similar to what you're looking for. I'd check to be sure it's there, but I can't seem to find my copy right now.
