Inter face
Geome try group
Specifies whether to use the whole object or
selected sub-objects, and which of the two
components (struts and joints) is displayed.
Apply To Entir e Obj ect—Applies Lattice to all edges
or segments in the object. When tur ned off,
applies L attice only to selected sub-objects p assed
up the stack. Default=on.
Note: When Apply To Entire Object is turned
off, unselected sub-objects render normally. For
example, if you convert a box to an editable mesh,
select one polygon, and then apply Lattice with
Apply To Entire Object turned off, the face does
not render, while the edges and vertices that form
that face are converted to struts and joints, and
the remaining faces render normally. However, if
you select the four edges surrounding the polygon
andturnoffIgnoreHiddenEdges,thestrutsand
joints are added to the object while al l faces render
as normal. If you turn on Struts group > Ignore
Hidden Edges, one of the polygon’s faces renders,
whi le the other doesn’t.
Joints Only From Ver tices—Displays only the joints
(polyhedra) generated by the vertices of the
original mesh.
Struts Only From Edges—Displays only the struts
(cylinders) generated by the segments of the
original mesh.
Both—Displays both struts and joints.
Struts group
Provides controls that affect the geometry of the
struts.
Radius—Specifies the radius of the struts.
Segments—Specifies the number of segments
along the str uts. Increase this value w hen you need
to deform or distort the str uts with subsequent
modifiers.
Sides—Specifies the number of sides around the
perimeter of the struts.
Material ID—Specifies the material ID to be used
for the struts. T he str uts and the joints can have
different material IDs, making it easy to assign
