|
|
* @brief manipulate objects in the scene independently of one another
|
||
|
|
*
|
||
|
|
* The class vtkInteractorStyleJoystickActor allows the user to interact
|
||
|
|
* with (rotate, zoom, etc.) separate objects in the scene independent of
|
||
|
|
* each other. The position of the mouse relative to the center of the
|
||
|
|
* object determines the speed of the object's motion. The mouse's velocity
|
||
|
|
* detemines the acceleration of the object's motion, so the object will
|
||
|
|
* continue moving even when the mouse is not moving.
|
||
|
|
* For a 3-button mouse, the left button is for rotation, the right button
|
||
|
|
* for zooming, the middle button for panning, and ctrl + left button for
|
||
|
|
* spinning. (With fewer mouse buttons, ctrl + shift + left button is
|
||
|
|
* for zooming, and shift + left button is for panning.)
