Wave Tool
 
 
 

The Wave tool lets you simulate waves in a single direction (as opposed to circular waves as found in Ripple).

The Wave tool has the following parameters.

Use: To:
Amplitude Scale the amount of warping distortion. Increase for more severe distortion.
Compression Warp pixels parallel to the wave direction.
Frequency Set the number of waves per frame. Increase for more waves, decrease for fewer.
Phase Shift the position of the waves along the direction of wave motion.
