* @class vtkParallelCoordinatesInteractorStyle
|
|
* @brief interactive manipulation of the camera specialized for parallel coordinates
|
|
*
|
|
* vtkParallelCoordinatesInteractorStyle allows the user to interactively manipulate
|
|
* (rotate, pan, zoom etc.) the camera.
|
|
* Several events are overloaded from its superclass
|
|
* vtkInteractorStyleTrackballCamera, hence the mouse bindings are different.
|
|
* (The bindings keep the camera's view plane normal perpendicular to the x-y plane.)
|
|
* In summary, the mouse events are as follows:
|
|
* + Left Mouse button triggers window level events
|
|
* + CTRL Left Mouse spins the camera around its view plane normal
|
|
* + SHIFT Left Mouse pans the camera
|
|
* + CTRL SHIFT Left Mouse dollys (a positional zoom) the camera
|
|
* + Middle mouse button pans the camera
|
|
* + Right mouse button dollys the camera.
|
|
* + SHIFT Right Mouse triggers pick events
|
|
*
|
|
* Note that the renderer's actors are not moved; instead the camera is moved.
