DESCRIPTION
     An orthographic camera defines a parallel projection from a viewpoint.
     This camera does not diminish objects with distance, as an
     SoPerspectiveCamera does. The viewing volume for an orthographic camera
     is a rectangular parallelepiped (a box).

     By default, the camera is located at (0,0,1) and looks along the negative
     z-axis; the position and orientation fields can be used to change these
     values. The height field defines the total height of the viewing volume;
     this and the aspectRatio field determine its width.

FIELDS
     SoSFFloat           height
          Height of the viewing volume.


FUNCTIONS
     SoOrthographicCamera *  SoOrthoCamCreate()
          Creates an orthographic camera node with default settings.

     SoType                  SoOrthoCamGetClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction,
     SoHandleEventAction, SoRayPickAction
          Sets the viewport and camera information in the state.
