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.
