This rollout lets you set the size and resolution of the lattice, and how it
displays and deforms.
Dimensions group
These options let you adjust the unit dimensions of the source volume, and
specify the number of control points in the lattice. Note that the point
dimensions are displayed beside the modifier name in the Stack list.
Radius, Height These two spinners display and let you adjust the length,
width, and height of the lattice. To create the space warp, drag the mouse in
the same way that you would to create a standard Cylinder primitive. Note
that these spinners don't exist in the object-modifier version of the FFD.
Label Displays the current number of controls points in the lattice (for
example: 4x8x4).
Set Number of Points Displays a dialog containing three spinners labeled
Side, Radial, and Height, plus OK/Cancel buttons. Specify the number of
control points you want in the lattice, and then click OK to make the change.
Side The number of control points around the perimeter of the lattice.
Radial The number of control points, radially, from the center to the outer
perimeter of the lattice.
Height The number of control points along the height of the lattice.
NOTE Make changes to the dimensions before you adjust the positions of the
lattice control points. When you change the number of control points with this
dialog, any adjustments you've already made to the control points are lost;
however, you can undo this use of the dialog.
Display group
These options affect the display of the FFD in viewports.
Lattice When on, lines are drawn connecting the control points to make a
grid. Although viewports can become cluttered when these extra lines are
drawn, they help to visualize the lattice.
Source Volume When on, the control points and lattice are displayed in their
unmodified state. This display is helpful when you're adjusting the source
volume to affect specific vertices that lie within or without it. See the All
Vertices and Only in Volume options, later in this topic.
