25 Perform(me: in out; L : Lin from gp;
26 Prm : Real from Standard;
27 Tol : Real from Standard;
28 F : Face from TopoDS)
29 ---Purpose: Perform the intersection between the
30 -- segment L(0) ... L(Prm) and the Shape <Sh>.
31 --
32 -- Only the point with the smallest parameter on the
33 -- line is returned.
34 --
35 -- The Tolerance <Tol> is used to determine if the
36 -- first point of the segment is near the face. In
37 -- that case, the parameter of the intersection point
38 -- on the line can be a negative value (greater than -Tol).

43 ---Purpose: True is returned when the intersection have been computed.

56 UParameter(me)
57 ---Purpose: Returns the U parameter of the intersection point
58 -- on the surface.
59 ---C++: inline

63 VParameter(me)
64 ---Purpose: Returns the V parameter of the intersection point
65 -- on the surface.

93
94 State(me)
95 ---Purpose: Returns the state of the point on the face.
96 -- The values can be either TopAbs_IN
97 -- ( the point is in the face)
98 -- or TopAbs_ON
99 -- ( the point is on a boudary of the face).
