mvNoise, Perlin noise - problem

[SilverWarior]

Maybe a bit late to ask, but, how Perlin Noise is different than a Plasma Cloud? Is there some advantage to use Perlin Noise?

The main diferences between Perlin Noise and Pasma Cloud are:
1. In Plasma Cloud you put subsequent pixels between the other two pixels while in Perlin Noise you actually place subsequent pixels moved a bit based on pseudorandom gradiant vector.
2. In Perlin Noise you usually pregenerate premutation table and use thet for making random textures for each octave and thus removes the need to be constantly generating random numbers. This in the end gives you better perfornamce since random number generation is quite slow.
3. In perlin noise you can define custom size and presistance for each octave with which you get fine controll on final texture.
