Public Member Functions inherited from Graphic3d_Structure
	Graphic3d_Structure (const Handle< Graphic3d_StructureManager > &theManager, const Handle< Graphic3d_Structure > &theLinkPrs=Handle< Graphic3d_Structure >())
	Creates a graphic object in the manager theManager. It will appear in all the views of the visualiser. The structure is not displayed when it is created.

virtual	~Graphic3d_Structure ()
	Suppresses the structure <me>. It will be erased at the next screen update.

Graphic3d_DisplayPriority	DisplayPriority () const
	Returns the current display priority for this structure.

void	SetDisplayPriority (const Graphic3d_DisplayPriority thePriority)
	Modifies the order of displaying the structure. Values are between 0 and 10. Structures are drawn according to their display priorities in ascending order. A structure of priority 10 is displayed the last and appears over the others. The default value is 5. Warning: If structure is displayed then the SetDisplayPriority method erases it and displays with the new priority. Raises Graphic3d_PriorityDefinitionError if Priority is greater than 10 or a negative value.

void	SetDisplayPriority (const Standard_Integer thePriority)

void	ResetDisplayPriority ()

void	SetZLayer (const Graphic3d_ZLayerId theLayerId)
	Set Z layer ID for the structure. The Z layer mechanism allows to display structures presented in higher layers in overlay of structures in lower layers by switching off z buffer depth test between layers.

	Returns the coordinates of the boundary box of the structure <me>. If <theToIgnoreInfiniteFlag> is TRUE, the method returns actual graphical boundaries of the Graphic3d_Group components. Otherwise, the method returns boundaries taking into account infinite state of the structure. This approach generally used for application specific fit operation (e.g. fitting the model into screen, not taking into account infinite helper elements). Warning: If the structure <me> is empty then the empty box is returned, If the structure <me> is infinite then the whole box is returned.

Graphic3d_TypeOfStructure	Visual () const
	Returns the visualisation mode for the structure <me>.
