This modifier shifts the shape of a mesh, curve, surface or lattice to any of a few predefined shapes (sphere, cylinder, cuboid).
It is equivalent to the To Sphere tool in Edit Mode, Shift-Alt-S and what other programs call "Spherify" or "Spherize", but, as written above, it is not limited to casting to a sphere.
The Smooth Modifier is a good companion to Cast, since the cast shape sometimes needs smoothing to look nicer or even to fix shading artifacts.
For performance reasons, this modifier only works with local coordinates. If the modified object looks wrong, you may need to apply its rotation Ctrl-A, especially when casting to a cylinder.
Menu to choose target shape of the projection.

- The factor to control blending between original and cast vertex positions. It is a linear interpolation: 0.0 gives original coordinates (i.e. modifier has no effect), 1.0 casts to the target shape. Values below 0.0 or above 1.0 exaggerate the deformation, sometimes in interesting ways.
The name of an object to control the effect. The location of this object's origin defines the center of the projection. Also, its size and rotation transform the projected vertices.
