Description

Base class for a compound handle to edit a bounding volume in the Scene view.

This class allows you to display a shape with up to six control handles for simultaneously editing the size and center of a bounding volume. Dragging on any one control handle will expand the volume along the control handle's axis. All classes that inherit from this class also gain the following modifier keys while a control handle is being dragged:

Alt: Pin the center of the volume to its location at the time the control handle was clicked and grow the size in both directions along the control handle's axis of movement.
Shift: Uniformly scale the volume along all enabled axes in proportion to its size at the time the control handle was clicked.

The handle rendered by this class's DrawHandle method is affected by global state in the Handles class, such as Handles.matrix and Handles.color.

See Also: Editor.OnSceneGUI, Handles.SetCamera.
