selection. When an FFD Space Warp is applied to an object, you can select the Control Points subobjects
and apply modifiers to the selection. The FFD Select modifier lets you select a different set of control points
for a different modifier.
Wave and Ripple
The Wave and Ripple Space Warps create linear and radial waves in the objects to which they are bound.
Parameters in the rollout help define the shape of the wave. Amplitude 1 is the wave’s height along the
X-axis, and Amplitude 2 is the wave’s height along its Y-axis. The Wave Length value defines how long each
wave is. The Phase value determines how the wave starts at its origin. The Decay value sets how quickly the
wave dies out. A Decay value of 0 maintains the same amplitude for the entire wave.
The Sides (Circles) and Segments values determine the number of segments for the X- and Y-axes. The
Division value changes the icon’s size without altering the wave effect. Figure 42.13 shows a Wave Space
Warp applied to a simple Box primitive. Notice that the Space Warp icon is smaller than the box, yet it
affects the entire object.

Note
Be sure to include enough segments in the bound object, or the effect won’t be visible. n
