If you have animated geometry (a NURBS or polygonal shape) on a path curve, you may choose to have the object deform as it travels along the path curve, matching the contours of the curve.
The Flow Path Object function creates a lattice around an object that is animated with path animation. There are two ways you can create the lattice: around the object, or around the path curve. Both methods will achieve the same result. However, you may find that one or the other is more convenient if you want to add deformations to the lattice afterwards to achieve some layered deformation effects. See Deform an object along a motion path curve.
By default, the lattice is created around the object.
