class DeflectionCurve from VrmlConverter 

    	---Purpose: DeflectionCurve    -  computes the presentation of
    	--          objects to be seen as  curves,   converts this  one into
    	--          VRML    objects    and    writes (adds)  into
    	--          anOStream.     All  requested properties  of   the
    	--          representation  are specify in  aDrawer.   
	--          This  kind of the presentation
    	--          is converted into IndexedLineSet ( VRML ).
        --          The computation will be made according to a maximal
        --          chordial deviation.

    ---Purpose: adds to the OStream the drawing of the curve aCurve with

    --          by the drawer aDrawer.
