class PolyhedronTool from IntPatch

    ---Purpose: Describe  the signature  of  a  polyedral surface with
    --          only triangular  facets and the necessary informations
    --          to compute the interferences.

uses
        Polyhedron    from IntPatch,
        XYZ           from gp,
    	Pnt           from gp,
    	Box           from Bnd,
	HArray1OfBox  from Bnd

raises  OutOfRange from Standard

is  Bounding       (myclass; thePolyh : Polyhedron from IntPatch)
    	    	    returns Box from Bnd;
    ---Purpose: Give the bounding box of the Polyhedron.
    ---C++: return const &
    ---C++: inline

    ComponentsBounding
       	    	   (myclass; thePolyh : Polyhedron from IntPatch)
    	    	    returns HArray1OfBox from Bnd;
    ---Purpose: Give the array of boxes. The box <n> corresponding 
    --          to the triangle <n>.
    ---C++: return const &
    ---C++: inline



    DeflectionOverEstimation
		   (myclass; thePolyh : Polyhedron from IntPatch)
    	    	    returns Real from Standard;
    ---Purpose: Give the tolerance of the polygon.
    ---C++: inline



-- Structure needings :

    NbTriangles	   (myclass; thePolyh : Polyhedron from IntPatch) 
    	    	    returns Integer from Standard;
    ---Purpose: Give the number of triangles in this polyedral surface.
    ---C++: inline


    Triangle	   (myclass; thePolyh : Polyhedron from IntPatch;
		    Index     : in Integer from Standard;
		    P1,P2,P3  : out Integer from Standard)
		    raises OutOfRange from Standard;
    ---Purpose: Give the indices  of  the 3 points of  the triangle of
    --          address Index in the Polyhedron.
    ---C++: inline


    Point	   (myclass; thePolyh : Polyhedron from IntPatch;
		    Index : in Integer)
		    returns Pnt from gp
		    raises OutOfRange from Standard;
    ---Purpose: Give the point of index i in the polyedral surface.
    ---C++: return const &
    ---C++: inline


    TriConnex	   (myclass; thePolyh : Polyhedron from IntPatch;
		    Triang	 : in Integer;
		    Pivot,Pedge	 : in Integer;
		    TriCon	 : out Integer;
		    OtherP	 : out Integer)
		    returns Integer
		    raises OutOfRange from Standard;
    ---Purpose: Gives the  addresse Tricon of   the triangle connexe to
    --          the triangle of address Triang by the edge Pivot Pedge
    --          and the third point of this  connexe triangle. When we
    --          are on  a free edge TriCon==0  but the function return
    --          the value of  the triangle in the  other side of Pivot
    --          on the free edge.  Used to turn around a vertex.
