FFD Object
The FFD object is the deformation object par excellence. An object can be freely deformed using any number of grid points. Hence the name - Free-Form eformation. The grid points act like small magnets on all object points that lie in the undeformed FFD object.
NoteIn contrast to the other deformation objects, you can only edit the grid points in Points mode, as they are not handles but actual points.
You can animate the FFD object by either creating morph target objects and thus controlling the FFD via the Morph Track in the timeline, or by animating the points via PLA (see PLA Track).
