I have noticed for quite som time that the perlin noise isn't really that random. It seems to be the same everytime the composition is restarted. Furthermore it seems very much like it's centered around 0, instead of being all over the place (which is desireable for me at least). A last issue with it is that two Noise nodes will produce the same result in a composition. Is all of this by design? In that I'll have to use the timebase (add to time) to get different results? These are the Vuo products of a composition running two times:
While these are the products of Processing running a similar sketch:
Processing seems to mix thing up a bit, so that you'll get a different result every time. It is also not centered around 0, but wil move (seemingly) randomly around in the drawing space without a seed.
