class TGLObject: public TGLLogicalShape

 Base-class for direct OpenGL renderers.
 This allows classes to circumvent passing of TBuffer3D and
 use user-provided OpenGL code.
 By convention, if you want class TFoo : public TObject to have direct rendering
 you should also provide TFooGL : public TGLObject and implement
 abstract functions SetModel() and SetBBox().
 TAttBBox can be used to facilitate calculation of bounding-boxes.
 See TPointSet3D and TPointSet3DGL.

Function documentation

Bool_t ShouldDLCache(const TGLRnrCtx& rnrCtx) const
 Decide if display-list should be used for this pass rendering,
 as determined by rnrCtx.
void UpdateBoundingBox()
 Update bounding box from external source.
 We call abstract SetBBox() and propagate the change to all
 attached physicals.
Bool_t SetModelCheckClass(TObject* obj, TClass* cls)
 Checks if obj is of proper class and sets the model.
 Protected helper for subclasses.
 Most sub-classes use exception-throwing SetModelDynCast() instead.
void SetAxisAlignedBBox(Float_t xmin, Float_t xmax, Float_t ymin, Float_t ymax, Float_t zmin, Float_t zmax)
 Set axis-aligned bounding-box.
 Protected helper for subclasses.
void SetAxisAlignedBBox(const Float_t* p)
 Set axis-aligned bounding-box.
 Protected helper for subclasses.
TClass* SearchGLRenderer(TClass* cls)
 Recursively search cls and its base classes for a GL-renderer
TClass* GetGLRenderer(TClass* isa)
 Return direct-rendering GL class for class isa.
 Zero is a valid response.
virtual ~TGLObject()
Bool_t KeepDuringSmartRefresh() const
 Kept from TGLLogicalShape
 virtual ELODAxes SupportedLODAxes() const { return kLODAxesNone; }
 Changed from TGLLogicalShape
{ return kTRUE; }
Bool_t SetModel(TObject* obj, const Option_t* opt = 0)
 TGLObject virtuals
void SetBBox()
 Abstract method from TGLLogicalShape:
 virtual void DirectDraw(TGLRnrCtx & rnrCtx) const = 0;
