88 Chapter 11: Space Warps and Particle Systems
The FFD(Box ) space warp is a box-shaped
lattice FFD object similar to the original FFD
modifiers. This FFD is available as both an object
modifier and a space warp. For information on the
object-modifier version, see
FFD (B ox/Cylinder)
Modifiers (page 1–677)
.
You create FFD space warps as separate objects
similarly to the way you create standard primitives:
by dragging the mouse in the viewport. The result
is a lattice of control points. The source lattice
of an FFD modifier is fitted to the geometry it’s
assigned to in the stack. This might be a whole
object or a sub-object selection of faces or vertices.
Because FFD space warps are separate objects, they
carry their own adjustable dimension p arameters
among the creation parameters.
You can apply object modifiers to space warp
objects. For example, you can use the Linked
XForm modifier with a space-warp FFD.
