IntPatch_Line Class Reference

Definition of an intersection line between two surfaces. A line may be either geometric : line, circle, ellipse, parabola, hyperbola, as defined in the class GLine, or analytic, as defined in the class ALine, or defined by a set of points (coming from a walking algorithm) as defined in the class WLine.

Member Function Documentation

IntPatch_IType IntPatch_Line::ArcType

(

)

const

Returns the type of geometry 3d (Line, Circle, Parabola, Hyperbola, Ellipse, Analytic, Walking, Restriction)

Standard_Boolean IntPatch_Line::IsTangent

(

)

const

Returns TRUE if the intersection is a line of tangency between the 2 patches.

Standard_Boolean IntPatch_Line::IsUIsoOnS1

(

)

const

Returns TRUE if the intersection is a U isoparametric curve on the first patch.

Standard_Boolean IntPatch_Line::IsUIsoOnS2

(

)

const

Returns TRUE if the intersection is a U isoparametric curve on the second patch.

Standard_Boolean IntPatch_Line::IsVIsoOnS1

(

)

const

Returns TRUE if the intersection is a V isoparametric curve on the first patch.

Standard_Boolean IntPatch_Line::IsVIsoOnS2

(

)

const

Returns TRUE if the intersection is a V isoparametric curve on the second patch.

void IntPatch_Line::SetValue	(	const Standard_Boolean	Uiso1,
		const Standard_Boolean	Viso1,
		const Standard_Boolean	Uiso2,
		const Standard_Boolean	Viso2
	)

To set the values returned by IsUIsoS1,.... The default values are False.

IntSurf_Situation IntPatch_Line::SituationS1

(

)

const

Returns the situation (INSIDE/OUTSIDE/UNKNOWN) of the first patch compared to the second one, when TransitionOnS1 or TransitionOnS2 returns TOUCH. Otherwise, an exception is raised.

IntSurf_Situation IntPatch_Line::SituationS2

(

)

const

Returns the situation (INSIDE/OUTSIDE/UNKNOWN) of the second patch compared to the first one, when TransitionOnS1 or TransitionOnS2 returns TOUCH. Otherwise, an exception is raised.

IntSurf_TypeTrans IntPatch_Line::TransitionOnS1

(

)

const

Returns the type of the transition of the line for the first surface. The transition is "constant" along the line. The transition is IN if the line is oriented in such a way that the system of vector (N1,N2,T) is right-handed, where N1 is the normal to the first surface at a point P, N2 is the normal to the second surface at a point P, T is the tangent to the intersection line at P. If the system of vector is left-handed, the transition is OUT. When N1 and N2 are colinear all along the intersection line, the transition will be.

• TOUCH, if it is possible to use the 2nd derivatives to determine the position of one surafce compared to the other (see Situation)
• UNDECIDED otherwise.

If one of the transition is TOUCH or UNDECIDED, the other one has got the same value.

IntSurf_TypeTrans IntPatch_Line::TransitionOnS2

(

)

const

Returns the type of the transition of the line for the second surface. The transition is "constant" along the line.
