class SectionPoint from Intf
---Purpose: Describes an intersection point between polygons and
-- polyedra.

is
-- User Interface :
Pnt (me)
returns Pnt from gp is static;
---Purpose: Returns the location of the SectionPoint.
---C++: return const &
ParamOnFirst (me)
returns Real from Standard is static;
---Purpose: Returns the cumulated Parameter of the SectionPoint on the
-- first element.
--
---C++: inline
ParamOnSecond (me)
returns Real from Standard is static;
---Purpose: Returns the cumulated Parameter of the section point on the
-- second element.
--
---C++: inline
TypeOnFirst (me)
returns PIType is static;
---Purpose: Returns the type of the section point on the first element.
--
---C++: inline
TypeOnSecond (me)
returns PIType is static;
---Purpose: Returns the type of the section point on the second
-- element.

Add1 : out Integer;
Add2 : out Integer;
Param : out Real) is static;
InfoFirst (me;
Dim : out PIType;
Addr : out Integer;
Param : out Real) is static;
---Purpose: Gives the datas about the first argument of the
-- Interference.

Add1 : out Integer;
Add2 : out Integer;
Param : out Real) is static;
InfoSecond (me;
Dim : out PIType;
Addr : out Integer;
Param : out Real) is static;
---Purpose: Gives the datas about the second argument of the
-- Interference.
Incidence (me)
returns Real is static;
---Purpose: Gives the incidence at this section point. The incidence
-- between the two triangles is given by the cosine. The best
-- incidence is 0. (PI/2). The worst is 1. (null angle).
IsEqual (me;
Other : in SectionPoint from Intf) -- in like me);
returns Boolean is static;
---Purpose: Returns True if the two SectionPoint have the same logical
-- informations.
--
---C++: alias operator==
---C++: inline
IsOnSameEdge (me;
Other : in SectionPoint from Intf) -- in like me);
returns Boolean is static;
---Purpose: Returns True if the two SectionPoints are on the same edge
-- of the first or the second element.
-- Constructor :

AddrO2 : in Integer;
ParamO : in Real;
DimeT : in PIType;
AddrT1 : in Integer;
AddrT2 : in Integer;
ParamT : in Real;
Incid : in Real)
returns SectionPoint;
---Purpose: Builds a SectionPoint with the respective dimensions
-- (vertex edge or face) of the concerned arguments and their
-- addresses in the Topological structure.

---Purpose: Builds a SectionPoint 2d with the respective dimensions
-- (vertex or edge) of the concerned arguments and their
-- addresses in the Topological structure.
Merge (me : in out;
Other : in out SectionPoint from Intf)
-- in out like me
