Lattice object is a global deformator object. Create it into an object and all the geometric points in the object are influenced by the lattice object.

The lattice object can be used as a deformation tool for modeling purposes, or as an animation tool. When activated, the tool provides three integer fields which define the point counts in three dimension.

Number of points in x, y and z dimensions

One can create a lattice over any object and deform it to deform the target object.

You can also move an object through a deformed lattice object to get a deformation effect applied.

Lattice object properties are explained in models/geometrics/lattice documentation.
