The Noise modifier modulates the position of an
object’s vertices along any combination of three
axes. This important animation tool simulates
random variations in an object’s shape.
Using a fractal setting, you can achieve random,
rippling patterns, like a flag in the wind. With
fractal settings, you can also create mountainous
terrain from flat geometry.

object. The Noise gizmo changes shape to help
you visualize the effects of changing par a meter
settings. The results of the Noise modifier are most
noticeable on objects that have greater numbers
of faces.
Most of the Noise parameters have an animation
controller. The only keys set by default are for
Phase.
