Radial lattice is needed for precise deformation of circular objects.

Mesh deform modifier may be used to deform circular/cylindrical/spherical objects but it is slow at first and does not deform precisely the captive objects at second. Therefore a radial lattice may be very useful to deform such objects.

It is possible to create a deformed radial lattice programmatically (lattice.data.points[].co_deform), but since the original coordinates of the lattice read only in bpy (lattice.data.points[].co), it is not possible to create radial lattice.
