package Intf 

	---Purpose: Interference computation  between polygons, lines  and
	--          polyhedra with only  triangular  facets. These objects
	--          are polygonal  representations of complex   curves and
	--          triangulated representations of complex surfaces.

--  Enumeration :

    enumeration PIType is EXTERNAL, FACE, EDGE, VERTEX;
    ---Purpose: Describes the different intersection  point types for this
    --          application.


--  Classes input data :

    deferred class Polygon2d;

    imported Array1OfLin;
    ---Purpose: Describes  a set of Straight Lines  to  intersect with the
    --          Polyhedron.



--	Classes output data :

    class SectionPoint;

    imported SeqOfSectionPoint;


    class SectionLine;

    imported SeqOfSectionLine;


    class TangentZone;

    imported SeqOfTangentZone;


    deferred class Interference;

-- Algorithms :

    class Tool;


    class InterferencePolygon2d;
    ---Purpose: Computes   the  interference between   two polygons in  2d.
    --          Result : points of intersections and zones of tangence.

    generic class InterferencePolygonPolyhedron;
    ---Purpose: Computes the interference  between a polygon or  a straight
    --          line and a polyhedron.   Points of intersection  and zones
    --          of tangence.
