const Handle_V3d_View &	View () const
	Returns the 3D view used at the time of construction.
virtual void	Directions (gp_Vec2d &D1, gp_Vec2d &D2, gp_Vec2d &D3) const
virtual void	Scaled (const Standard_Boolean On=Standard_False)
	to compute with the given scale and translation.
virtual Standard_Boolean	Perspective () const
	Returns True if there is a perspective transformation.
virtual const gp_GTrsf &	Transformation () const
	Returns the active transformation.
virtual const gp_GTrsf &	InvertedTransformation () const
	Returns the active inverted transformation.
virtual const gp_Trsf &	FullTransformation () const
	Returns the original transformation.

	Returns the focal length.
virtual void	Transform (gp_Vec &D) const
virtual void	Transform (gp_Pnt &Pnt) const
virtual void	Project (const gp_Pnt &P, gp_Pnt2d &Pout) const

virtual gp_Lin	Shoot (const Standard_Real X, const Standard_Real Y) const
	return a line going through the eye towards the 2d point <X,Y>.
Standard_Real	DepthMin () const
	Returns the minimum depth value (if clipping plane defined). Should be used when call ::Shoot() to compute eyeline.
Standard_Real	DepthMax () const
	Returns the maximum depth value (if clipping plane defined). Should be used when call ::Shoot() to compute eyeline.
void	DepthMinMax (const Standard_Real theDepthMin, const Standard_Real theDepthMax)
	Setup the min/max depth values (doesn't affect projection functionality itself). Should be used when call ::Shoot() to compute eyeline.
