### Data Members

        private:

          TVirtualPad& fPad       the pad we paint into.
                Bool_t fBuilding  is scene being built?

## Class Description

     TViewer3DPad

     Provides 3D viewer interface (TVirtualViewer3D) support on a pad.
     Will be merged with TView / TView3D eventually.

Bool_t PreferLocalFrame() const

     Indicates if we prefer positions in local frame. Always false - pad
     drawing is always done in master frame.

void BeginScene()

     Open a scene on the viewer

void EndScene()

     Close the scene on the viewer

Int_t AddObject(const TBuffer3D & buffer, Bool_t * addChildren)

     Add an 3D object described by the buffer to the viewer. Returns flags
     to indicate:
     i) if extra sections of the buffer need completing.
     ii) if child objects of the buffer object should be added (always true)

Int_t AddObject(UInt_t /*placedID*/, const TBuffer3D & buffer, Bool_t * addChildren)

     We don't support placed ID shapes - ID is discarded

Bool_t OpenComposite(const TBuffer3D & /*buffer*/, Bool_t * /*addChildren*/)

     Composite shapes not supported on this viewer currently - ignore.
     Will result in a set of individual component shapes

void CloseComposite()

void AddCompositeOp(UInt_t /*operation*/)

                   Bool_t BuildingScene() const
                  TClass* Class()
                  TClass* IsA() const
                     void ShowMembers(TMemberInspector& insp, char* parent)
                     void Streamer(TBuffer& b)
                     void StreamerNVirtual(TBuffer& b)
