/**
* @class vtkInteractorStyleTerrain
* @brief manipulate camera in scene with natural view up (e.g., terrain)
*
* vtkInteractorStyleTerrain is used to manipulate a camera which is viewing
* a scene with a natural view up, e.g., terrain. The camera in such a
* scene is manipulated by specifying azimuth (angle around the view
* up vector) and elevation (the angle from the horizon).
*
* The mouse binding for this class is as follows. Left mouse click followed
* rotates the camera around the focal point using both elevation and azimuth
* invocations on the camera. Left mouse motion in the horizontal direction
* results in azimuth motion; left mouse motion in the vertical direction
* results in elevation motion. Therefore, diagonal motion results in a
* combination of azimuth and elevation. (If the shift key is held during
* motion, then only one of elevation or azimuth is invoked, depending on the
* whether the mouse motion is primarily horizontal or vertical.) Middle
* mouse button pans the camera across the scene (again the shift key has a
* similar effect on limiting the motion to the vertical or horizontal
* direction. The right mouse is used to dolly (e.g., a type of zoom) towards
* or away from the focal point.
*
* The class also supports some keypress events. The "r" key resets the
* camera. The "e" key invokes the exit callback and by default exits the
* program. The "f" key sets a new camera focal point and flys towards that
* point. The "u" key invokes the user event. The "3" key toggles between
* stereo and non-stero mode. The "l" key toggles on/off a latitude/longitude
* markers that can be used to estimate/control position.
