Chapter 42: Using Space Warps
Strength and Decay values. Additional options make the gravity planar or spherical. You can turn on the
Range Indicators to display a plane or sphere where the gravity is half its maximum value.
Wind
The Wind Space Warp causes objects to accelerate. The Parameters rollout includes Strength and Decay values.
Additional options make the gravity planar or spherical. The Turbulence value randomly moves the objects in
different directions, and the Frequency value controls how often these random turbulent changes occur. Larger
Scale values cause turbulence to affect larger areas, but smaller values are wilder and more chaotic.
You can turn on the Range Indicators just like the Gravity Space Warp. Figure 42.8 shows the Wind Space
Warp pushing the particles being emitted from a Super Spray particle system.
FIGURE 42.8
You can use the Wind Space Warp to blow particles and dynamic objects.

Displace
The Displace Space Warp is like a force field: It pushes objects and is useful when applied to a particle sys-
tem. It can also work on any deformable object in addition to particle systems. The strength of the displace-
ment can be defined with Strength and Decay values or with a grayscale bitmap.

The Strength value is the distance that the geometry is displaced and can be positive or negative. The Decay
value causes the displacement to decrease as the distance increases. The Luminance Center is the grayscale
point where no displacement occurs; any color darker than this center value is moved away, and any
brighter areas move closer.
