Evaluate noise map. v = a_noise(x,y,z)?
I'd like to evaluate a noise map (or any 3d map) at an arbitrary point in space.
v = a_noise(u,v,w)
Guess it would return an rgb value. With or without other mappings or materials involved. I guess ideally I would do my own mapping. So u,v,w would be 0.0 - 1.0 I presume.
I spent some time poking around, but couldn't find it. But I'm a total noob.
