class TVolumeView: public TObjectSet, public TAtt3D

             ,fListOfAttributes(0)

 This ctor creates a TVolumeView structure from the "marked" nodes
 of the "viewNode" input structure
 It re-calculates all positions according of the new topology
 All new TVolume became UNMARKED though

             ,fListOfAttributes(0)

 This ctor creates a TVolumeView structure containing:

   - viewNode on the top
   - skip ALL node from the original viewNode untill topNode found
   - include all "marked" node below "topNode" if any
     topNode is always included

 It re-calculates all positions according of the new topology

             ,fListOfAttributes(0)

 This ctor creates a TVolumeView structure containing:

   - viewNode on the top
   - skip ALL node from the original viewNode untill topNodeName found
   - include all "marked" node below "topNodename" if any
     topNodeName is always included

 It re-calculates all positions according of the new topology

             ,fListOfAttributes(0)

 This ctor creates a TVolumeView structure containing:

   - viewNode on the top
   - skip ALL node from the original viewNode untill topNodeName found
   - include all "marked" node below "topNodename" if any
     topNodeName is always included

 It re-calculates all positions according of the new topology

 Creates TVolumeView (view) with a topology similar with TVolume *pattern

  Parameters:

  pattern        - the pattern dataset
  iopt = kStruct - clone only my structural links
         kAll    - clone all links
         kRefs   - clone only refs
         kMarked - clone marked (not implemented yet) only

   All new-created sets become the structural ones anyway.

-*-*-*Compute distance from point px,py to a TVolumeView
*-*                  ===========================================
*-*  Compute the closest distance of approach from point px,py to the position of
*-*  this node.
*-*  The distance is computed in pixels units.
-
*-*  It is restricted by 2 levels of TVolumes
-

-*-*-*-*-*-*-*-*Draw Referenced node with current parameters
*-*                   =============================================

 Calculate the position of the vertrex of the outlined cube in repect
 of the given TVolumeView object

  GetRange

  Calculates the size of 3 box the node occupies.
  Return:
    two floating point arrays with the bound of box
     surroundind all shapes of this TModeView

 calculate  transformation  master = (M-local->master )*local + (T-local->master )
  where
     M-local->master - rotation matrix 3 x 3 from the master node to the local node
     T-local->master - trasport vector 3 from the master node to the local node

 returns a "master" pointer if transformation has been found
        otherwise 0;

 calculate  transformation  master = (M-local->master )*local + (T-local->master )
  where
     M-local->master - rotation matrix 3 x 3 from the master node to the local node

-*-*-*-*-*-*-*-*Paint Referenced node with current parameters
*-*                   ==============================================
-
*-*  vis = 1  (default) shape is drawn
*-*  vis = 0  shape is not drawn but its sons may be not drawn
*-*  vis = -1 shape is not drawn. Its sons are not drawn
*-*  vis = -2 shape is drawn. Its sons are not drawn
-

 It draw the TVolumeView layers from the iFirst one (form the zero) till
 iLast one reached.
