Ripples
As the name suggests, the Ripples texture can be used to create the effect of ripples on a watery surface.
Controls are given for the value at the peak of the wave (Crest) and at the bottom of the wave (Trough).
As with other textures, there is also a transparency control given to these values. Instead of using a fractal
algorithm for creating the variance in this texture, there is a control for the number of sources that create the
ripples. Wavelength controls the distance between each wave and is essentially used for scaling the effect.
Phase controls the position of the individual waves. This option has more to do with animation, because
animating the Phase value will cause the ripples to move. The default settings of the Ripples texture are
demonstrated in
Figure 3-16
