Another blender tutorials have fun making a mushroom with lattice.. A Lattice is essentially a simple container that can be used to deform and manipulate a more complex mesh in a non-destructive manner (i.e. A lattice can be used to seriously deform a mesh then, if the lattice is later removed, the mesh can automatically return to its original shape). On its own, a Lattice serves no purpose whatsoever since it can't be seen in a rendered image. Its only use is to manipulate another object and so, to be useful, we need to associate another object with it. The current method for doing this is by applying a "Lattice Modifier" to a Blender object.
