Hi
I'm trying to make a plugin with filterMeister and i would like to know how the native clouds Filter in photoshop works as i'm doing something very similar to that.

If anyone knows the equations and math involed in generating clouds or maybe an online resource site where i can find out more info i'd greatly apprechiate it.
So far my own google "research" has not proved very succesful.
Thanks

The method is called perlin noise. Basically you generate noise, scale it up by various factors and mix all of these noise layers.

Better ask such questions on the FMML list. I know at least of one guy on the FMML list that wrote such an algorithm for one of his plugins.
