Ponds are 2D fluids that use a spring mesh solver and a height field. With the pond options and attributes, you can set the size and color of your fluid surface.
You can generate waves, bubbles, and ripples in the fluid surface using Wakes. See Create wakes. Increasing the size of your pond extends the range of your waves and ripples.
The Pond menu items function in almost the same manner as the Ocean menu items. For information on Pond menu items and attributes, search the Maya Help for Ocean menu items and attributes.
