// .NAME vtkInteractorStyleTerrain - manipulate camera in scene with natural view up (e.g., terrain)
// .SECTION Description
// 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.
