	Visual3d_ViewManager (const Handle< Aspect_GraphicDevice > &aDevice)
	Creates a 3D visualizer.
void	Activate ()
	Activates all the views of the manager <me>.
void	Deactivate ()
	Deactivates all the views of the manager <me>.
virtual void	Destroy ()
	Deletes and erases the 3D visualiser <me>.
	~Visual3d_ViewManager ()
void	Erase ()
	Erases all of the structures displayed in the visualiser <me>.
void	Redraw () const
	Redraws all the displayed structures.
void	Remove ()
	Deletes and erases the 3D visualiser <me>.
void	Update () const
	Updates screen in function of modifications of the structures. Category: Methods to modify the class definition Warning: Not necessary if the update mode is TOU_ASAP.
Handle_Visual3d_HSetOfView	ActivatedView () const
	Returns the group of views activated in the visualiser <me>.
void	ConvertCoord (const Handle< Aspect_Window > &AWindow, const Graphic3d_Vertex &AVertex, Standard_Integer &AU, Standard_Integer &AV) const
	Applies the view orientation transformation, the view mapping transformation and view clip, the display transformation to the vertex <AVertex>. Returns the pixel coordinates <AU>, <AV>. Warning: Returns <AU> = <AV> = IntegerLast () if the evaluation is impossible. -- Bad Window, Numeric error...
Graphic3d_Vertex	ConvertCoord (const Handle< Aspect_Window > &AWindow, const Standard_Integer AU, const Standard_Integer AV) const
	Applies the inverse of the display transformation, the inverse of the view mapping transformation and view clip, the inverse of the view orientation transformation to the pixel coordinates <AU>, <AV>. Returns the world coordinates <AVertex>. Warning: Returns AVertex (X, Y, Z) with X = Y = Z = RealLast () if the evaluation is impossible. -- Bad Window, Numeric error...

	Applies the inverse of the display transformation, the inverse of the view mapping transformation and view clip, the inverse of the view orientation transformation to the pixel coordinates <AU>, <AV>. Returns the world coordinates <AVertex> and projection ray <AVector>. Warning: Returns AVertex (X, Y, Z) with X = Y = Z = RealLast () and AVector (VX, VY, VZ) with VX = VY = VZ = 0. if the evaluation is impossible. -- Bad Window, Numeric error...

	Returns Standard_True if the view associated to the window <AWindow> exists and is activated. <TheViewId> contains the internal identification of the associated view.
const Handle_Visual3d_Layer &	UnderLayer () const
