because the objects themselves will never be rendered. They are used only to give the fluid simulation its initial
shape.
I placed four Inflow objects among the Fluid objects. These are shown from below (Ctrl+number pad key

in purple. (The image is repeated in the color insert.) I placed these Inflow objects slightly
lower than the Fluid objects, so they are visible only from the underside of the riverbed mesh. Note that in both
of these figures, the riverbed itself is seen in Wireframe view mode. The Inflow objects are all angled so that
their local x-axes point downstream, as you can see in the direction of the local axis manipulator for the selec-
ted sphere in the figure, and their initial velocity is set to be positive in the x-axis. Each one was adjusted after
several experimental bakes to keep the flow and level of the creek's water convincing.
