The Radial Ripple node

---

The Radial Ripple node ripples its input image using concentric circles. Unlike the other ripple nodes, you cannot set how it works in the Drawing Window; you must use its XSheet columns:

• The Spacing sets the distance between each ripple

• The Phase sets how far the ripples have spread out from the center, as a phase angle; a setting of 0 degrees (or a multiple of 360 degrees) means a new ripple is just starting to form, whereas a setting of 180 degrees (± plus or minus a multiple of 360 degrees) means the first ripple has spread by half the Spacing

• The Intensity sets the intensity of rippling: at 0% there is no change, at 100% the image is still recognizable, and at higher values the distortion becomes more extreme

• The E/W and N/S values set the center of the circles.

To get an effect of spreading ripples, you should in-between from one value in the Phase column to another.
