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.
