+
+A framework for filtering the computation results of an HLRBRep_PolyAlgo
+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.
