Gizmo/Center

Examples of gizmos:
Left: Gizmo for a bend modifier
Right: Gizmo for UVW mapping

Many modifiers display in viewports as a box-like apparatus called a gizmo, which initially surrounds the selected object. A gizmo acts like a kind of container that transfers the modification to the object to which it's attached.

You can move, scale, and rotate a gizmo as you would any object, altering the effect of the modifier on the object.

A modifier has its own center, marked with a 3D-pivot point like other objects in gmax. You can move a modifier's center, altering the effect of the modifier on the object.
