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

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.
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()
 Kept from TGLLogicalShape
 virtual ELODAxes SupportedLODAxes() const { return kLODAxesNone; }
 Changed from TGLLogicalShape
{ return kTRUE; }
Bool_t SetModel(TObject* obj, Option_t* opt = 0)
 TGLObject virtuals
void SetBBox()
 Abstract method from TGLLogicalShape:
 virtual void DirectDraw(TGLRnrCtx & rnrCtx) const = 0;
