Perlin Noise for iPhone/iPad?

Question

How can i get a sand effect in perlin-noise ? Do somebody have any tutorial to implement perlin noise in iPhone ?

Answer 1

It's really straightforward.

Objective-C is a superset of C so just take original source code (that can be found here), save it in a .c (this is not a requirement) and use it. You will have to understand how perlin noise works to be able to correctly tweak parameters but I personally did it and it worked great.
