DESCRIPTION

       This group node traverses its children, in order,  several  times,  applying  a  different
       matrix  each time. The matrices are stored in the multiple-value matrix field. Each matrix
       is concatenated to the  current  transformation  matrix,  and  all  of  the  children  are
       traversed.  This  allows  the  user  to  put multiple copies of the same data in different
       locations easily and efficiently.

       Traversing the Nth child sets the current switch value to N, for use with inherited switch
       values (see SoSwitch).

FIELDS

     SoMFMatrix          matrix
          Set of matrices to apply to children.

METHODS

                         SoMultipleCopy()
          Creates a multiple copy node with default settings.

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

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
          Traverses  all  children  for  each matrix, saving and restoring state before and after
          each traversal.

     SoSearchAction
          Traverses all children once, setting the inherited switch value to SO_SWITCH_ALL first.
