class HLRToShape from HLRBRep
    	---Purpose: A framework for filtering the computation
    	-- results of an HLRBRep_Algo algorithm by extraction.
    	-- From the results calculated by the algorithm on
    	-- a shape, a filter returns the type of edge you
    	-- want to identify. You can choose any of the following types of output:
    	-- -   visible sharp edges
    	-- -   hidden sharp edges
    	-- -   visible smooth edges
    	-- -   hidden smooth edges
    	-- -   visible sewn edges
    	-- -   hidden sewn edges
    	-- -   visible outline edges
    	-- -   hidden outline edges.
    	-- -   visible isoparameters and
    	-- -   hidden isoparameters.
    	-- Sharp edges present a C0 continuity (non G1).
    	-- Smooth edges present a G1 continuity (non G2).
    	-- Sewn edges present a C2 continuity.
    	-- The result is composed of 2D edges in the
    	-- projection plane of the view which the
    	-- algorithm has worked with. These 2D edges
    	-- are not included in the data structure of the visualized shape.
    	-- In order to obtain a complete image, you must
    	-- combine the shapes given by each of the chosen filters.
    	-- The construction of the shape does not call a
    	-- new computation of the algorithm, but only
    	-- reads its internal results.
        -- The methods of this shape are almost identic to those of the HLRBrep_PolyHLRToShape class.
