class PolyHLRToShape 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.
