class HLRPolyShape from StdPrs

inherits Root from Prs3d
    	---Purpose: Instantiates Prs3d_PolyHLRShape to define a
    	-- display of a shape where hidden and visible lines are
    	-- identified with respect to a given projection.
    	-- StdPrs_HLRPolyShape works with a polyhedral
    	-- simplification of the shape whereas
    	-- StdPrs_HLRShape takes the shape itself into
    	-- account. When you use StdPrs_HLRShape, you
    	-- obtain an exact result, whereas, when you use
    	-- StdPrs_HLRPolyShape, you reduce computation
    	-- time but obtain polygonal segments.
uses

    Drawer       from Prs3d,

is
    Add(myclass; aPresentation: Presentation from Prs3d;
    	    	 aShape       : Shape        from TopoDS;
                 aDrawer      : Drawer       from Prs3d;
		 aProjector   : Projector    from Prs3d);
    	---Purpose: Defines the hidden line removal display of the
    	-- topology aShape in the projection defined by
    	-- aProjector. The shape and the projection are added
    	-- to the display aPresentation, and the attributes of the
    	-- elements present in the aPresentation are defined by
    	-- the attribute manager aDrawer.
