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.

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.
