withShare : Boolean from Standard=Standard_True;

relative : Boolean from Standard=Standard_False;

---Purpose: if the boolean <relative> is True, the
-- deflection used for the polygonalisation of
-- each edge will be <defle> * Size of Edge.
-- the deflection used for the faces will be the maximum
-- deflection of their edges.
--
-- if <shapetrigu> is True, the triangulation, if exists
-- with a correct deflection, can be used to re-triangulate
-- the shape.
--
-- if <inshape> is True, the calculated
-- triangulation will be stored in the shape.
