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.
