class TAxis3D: public TNamed

   The 3D axis painter class


  This class provide up to 3 axice to any 3D ROOT plot and
  "ZOOM" service.
  ExecuteEvent() method does provide zooming and moving a projection
  3D object within TPad client area. With Zoom mode on the user can access
  TAxis3D context menu and set /change the attributes of axice all together
  or separately.

  To add the 3D rulers to any 3D view one has to create
  an instance of this class and Draw it.

   TAxis3D rulers;
   rulers.Draw();

  One can use a static method to create ruler and attach it to the current gPad

   TAxis3D::ToggleRulers(); // Brings the 3D axice up
   TAxis3D::ToggleRulers(); // next calls remove the rulers from the TPad etc

   To activate Zoomer one may call

   TAxis3D::ToggleZoom();

  each time one needs move or zoom the image. Then the user can:
    -  move:
 

    -  zoom:
 

  its 3D view with <left-mouse button> press / move.
  The "Zoom" deactivates itself just the user release the <left-mouse button>

  To change attributes of the rulers attached to the current Pad, one may
  query its pointer first:

  TAxis3D *axis = TAxis3D::GetPadAxis(); // Ask axis pointer
  if (axis) {
    TAxis3D::ToggleRulers()     // To pop axice down
    axis->SetLabelColor(kBlue); // Paint the axice labels with blue color
    axis->SetAxisColor(kRed);   // Paint the axice itself with blue color
    TAxis3D::ToggleRulers()     // To pop axice up
  }

 The attributes of the created axice are affected by the current style
 (see TStyle class ) and Set... methods of this class

  For example:

   gStyle->SetAxisColor(kYellow,"X");
   gStyle->SetAxisColor(kYellow,"Y");
   gStyle->SetAxisColor(kYellow,"Z");

   gStyle->SetLabelColor(kYellow,"X");
   gStyle->SetLabelColor(kYellow,"Y");
   gStyle->SetLabelColor(kYellow,"Z");

   TAxis3D::ToggleRulers();
   TAxis3D::ToggleRulers();

  will draw all axice and labels with yellow color.
