DragControls

Drag-and-drop controls for scene objects. Picking uses a CPU {@link Raycaster}. With the default mouse mapping the left and middle buttons pan the picked object across a camera-facing plane and the right button rotates it around the camera’s up and right axes; one touch pans. Hover tracking runs for mouse and pen pointers only. Dispatches hoveron, hoveroff, dragstart, drag, and dragend with the affected object in event.object.
