DESCRIPTION
       This  group node is similar to the SoSeparator node in that it saves state before traversing its children
       and restores it afterwards. However, it saves only the current transformation; all other state is left as
       is.   This  node can be useful for positioning a camera, since the transformations to the camera will not
       affect the rest of the scene, even through the camera will view the scene. Similarly, this  node  can  be
       used to isolate transformations to light sources or other objects.


METHODS
                         SoTransformSeparator()
          Creates a transform separator node with default settings.

                         SoTransformSeparator(int nChildren)
          Constructor that takes approximate number of children.

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


ACTION BEHAVIOR
       SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoGetMatrixAction, SoRayPickAction
          Saves   the   current  transformation  state,  traverses  all  children,  and  restores  the  previous
          transformation state.


FILE FORMAT/DEFAULTS
       TransformSeparator {
       }
