The Lattice object is a constructor based deformator. It is a three dimensional grid which is typically used for deforming freeform objects, such as SDS and NURBS surfaces.

The lattice object defines only attributes which specify the number of control points in each dimensions.

When a lattice object is created, the initial state of it is taken as the state of no deformation. Any modification applied to the lattice object will then deform the target objects accordingly.
