generic class IntConicCurveGen from IntCurve (
             TheImpTool     as any; -- as ImpTool from IntImpParGen

inherits Intersection from IntRes2d
		       

	---Purpose: Generic algorithm to intersect a conic from gp and
	--          a parametric  curve.  This class  uses   the class
	--          IConicTool    from  IntCurve,    and  Domain  from
	--          IntCurve.  The  template class for  the PCurveTool
	--          is  given in  the package IntImpParGen  (ParTool).
	--          The  methods  used  to   know  the result  of  the
	--          intersection  are  inherited  from   the     class
	--          Intersection from IntRes2d.
	-- 
	--          This algorithm is called from the IntCurveCurveGen 
	--          class.
