Noise Visualization Strangeness

Recommended Posts

Hi!

 

I'm trying to visualize a Unified Noise with some particles. However when I do, the particles just go in one direction. If I, for example, plug in an Anti Aliased Noise of the same type (Perlin) instead it seems to work (see image below for comparison). What am I doing wrong? File attached.

First of all, your noise output value is a float, which means it will put the same value into all 3 fields of the force vector - this is the reason why it goes in a same direction.

The reason why AA noise goes both ways (in the same direction) is that the output values are between -0.5 and 0.5 and unified noise output values are between 0 and 1.

What  you want to do is change the noise signature to 3d input, 3d noise and also potentially fit the output so its for example between -1 and 1.
