The Bend modifier can be used to bend trees.

Caution
In order for the Displace modifier to work, the surface requires a dense mesh, which can lead to very high poly-
gon counts. n
The Displace modifier parameters include Strength and Decay values. You can also specify the dimensions
of the gizmo. A cylindrical-shaped gizmo can be capped or uncapped. The alignment parameters let you
align the gizmo to the X-axis, Y-axis, or Z-axis, or you can align it to the current view. The rest of the
parameters deal with displacing the surface using a bitmap image. Figure 11.11 shows a Quad Patch with
the Plane-shaped gizmo applied with a Strength value of 25. To the right is a Quad Patch with the Sphere-
shaped gizmo.
Cross-Ref
The Displace modifier can also alter an object’s geometry using a grayscale bitmap image. This is similar to a
Displacement map, which is covered in Chapter 17, “Adding Material Details with Maps.” In many ways, the
Displace gizmo works like the Conform compound object. You can learn about the Conform compound object in
Chapter 27, “Working with Compound Objects.” n
