|
*
|
||
|
|
* vtkInteractorStyleJoystickCamera allows the user to move (rotate, pan,
|
||
|
|
* etc.) the camera, the point of view for the scene. The position of the
|
||
|
|
* mouse relative to the center of the scene determines the speed at which
|
||
|
|
* the camera moves, and the speed of the mouse movement determines the
|
||
|
|
* acceleration of the camera, so the camera continues to move even if the
|
||
|
|
* mouse if 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.)
