Generates ripples by displacing points along the up direction specified.
Using Ripple in the viewer
Select the points for the ripple.
This tool works well when there are many points selected. If you are placing a ripple on a grid, increase the rows and columns.
Click the Ripple tool on the Deform tab.
Use the Frequency, Height, and Wave Decay parameters to create the ripple.
The wave decay default setting is very high. Decrease its value for a more visible ripple effect.
