The Lattice modifier converts the segments or
edges of a shape or object into cylindrical str uts
w ith optional joint polyhedra at the vert ices. Use
this either to create renderable structural geometry
based on the mesh topology, or as an alternate
method to achieve a rendered wireframe effect.
Top: Joints only
Middle: Struts only
Bottom: Both (joints and struts)
Note: This modifier can act on the whole object or
on sub-object selections in the stack.
Tip: You can combine the Scatter compound object
(page 1–313)
w ith the Lattice modifier to place
any object you want as a joint, rather than the
provided polyhedra. To do this, create your mesh
distribution object and your source object (for
example, a box). Use Scatter to scatter the box at
the vertices of t he distr ibution object. (Be sure to
use the Copy option rather than Instance.) In the
Scatter Display parameters, hide the distribution
object. Select the original object that was used as
a distribution object, apply Lattice to it, and turn
off the joints. You’ll have two coincident objects:
