virtual ~TGLObject ()
virtual Bool_t KeepDuringSmartRefresh () const
virtual Bool_t ShouldDLCache (const TGLRnrCtx &rnrCtx) const
 Decide if display-list should be used for this pass rendering, as determined by rnrCtx.
virtual void UpdateBoundingBox ()
 Update bounding box from external source.
- Public Member Functions inherited from TGLLogicalShape
 TGLLogicalShape ()
 global flag for usage of display-lists in shapes that use vertex arrays
 TGLLogicalShape (const TBuffer3D &buffer)
 Constructor from TBuffer3D.
 TGLLogicalShape (TObject *obj)
 Constructor with external object.
virtual ~TGLLogicalShape ()
 Destroy logical shape.
void AddRef (TGLPhysicalShape *phys) const
 Add reference to given physical shape.
virtual Bool_t AlwaysSecondarySelect () const
const TGLBoundingBoxBoundingBox () const
void DestroyPhysicals ()
 Destroy all physicals attached to this logical.
virtual void DLCacheClear ()
 Clear all entries for all LODs for this drawable from the display list cache but keeping the reserved ids from GL context.
virtual void DLCacheDrop ()
 Drop all entries for all LODs for this drawable from the display list cache, WITHOUT returning the reserved ids to GL context.
virtual void DLCachePurge ()
 Purge all entries for all LODs for this drawable from the display list cache, returning the reserved ids to GL context.
virtual UInt_t DLOffset (Short_t) const
virtual void Draw (TGLRnrCtx &rnrCtx) const
 Draw the GL drawable, using draw flags.
virtual void DrawHighlight (TGLRnrCtx &rnrCtx, const TGLPhysicalShape *pshp, Int_t lvl=-1) const

TObjectID () const
virtual Bool_t IgnoreSizeForOfInterest () const
 Return true if size of this shape should be ignored when determining if the object should be drawn.
void InvokeContextMenu (TContextMenu &menu, UInt_t x, UInt_t y) const
 Invoke popup menu or our bound external TObject (if any), using passed 'menu' object, at location 'x' 'y'.
virtual void ProcessSelection (TGLRnrCtx &rnrCtx, TGLSelectRecord &rec)
 Virtual method called-back after a secondary selection hit is recorded (see TGLViewer::HandleButton(), Ctrl-Button1).
virtual Short_t QuantizeShapeLOD (Short_t shapeLOD, Short_t combiLOD) const
 Logical shapes usually support only discreet LOD values, especially in view of display-list caching.
UInt_t Ref () const
Bool_t SetDLCache (Bool_t cached)
 Modify capture of draws into display list cache kTRUE - capture, kFALSE direct draw.
void StrongRef (Bool_t strong) const
void SubRef (TGLPhysicalShape *phys) const
 Remove reference to given physical shape, potentially deleting this object when hitting zero ref-count (if fRefStrong is true).
virtual ELODAxes SupportedLODAxes () const
virtual Bool_t SupportsSecondarySelect () const
UInt_t UnrefFirstPhysical ()
 Unreferenced first physical in the list, returning its id and making it fit for destruction somewhere else.
void UpdateBoundingBoxesOfPhysicals ()
 Update bounding-boxed of all dependent physicals.
