List the ways objects can be deformed.

What will be an ideal response?

You can soft edit a curve or a surface. Control points of objects can be aligned by setting points or flattened to a plane by projection. Shapes of objects can be manipulated by shearing, twisting, bending, and tapering. To manipulate individual surface elements of a polysurface or a portion of a surface, it is advisable to shear, twist, bend, or taper selected control points. To simplify a curve or a surface, you apply a smoothing operation or make them uniform. To handle a set of polysurfaces collectively, you attach them to a backbone surface, stretch them to extend or shorten a portion of them, use cage for editing, and deform it as if the objects are being acted upon by a maelstrom.
