DESCRIPTION

       The  SoShuttle  class  is  derived  from  SoTranslation,  so  it  applies  a  translation  to the current
       transformation. Using engines connected to the realTime global field, the translation value  is  animated
       over  time  between two fixed translations, achieving a shuttling effect. The period of the motion can be
       adjusted by changing the speed field. The current translation at any time is available in the translation
       field, inherited from SoTranslation

FIELDS

     SoSFVec3f           translation0
     SoSFVec3f           translation1
          These define the two fixed translations that are interpolated to create the shuttling motion.

     SoSFFloat           speed
          Defines the speed of the shuttle, in cycles per second.

     SoSFBool            on
          Allows applications to enable or disable the motion easily.

METHODS

                         SoShuttle()
          Creates a shuttle node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
          Concatenates interpolated translation value with the current transformation matrix.

     SoGetMatrixAction
          Returns transformation matrix specified by the interpolated translation.
