Detailed Description

Implementation of the intersection between two quadric patches : Plane, Cone, Cylinder or Sphere.

Member Enumeration Documentation

enum IntPatch_ImpImpIntersection::IntStatus

Enumerator
IntStatus_OK	OK. Good intersection result.
IntStatus_InfiniteSectionCurve	Intersection curve is too long (e.g. as in the bug #26894). We cannot provide precise computation of value and derivatives of this curve having used floating-point model determined by IEEE 754 standard. As result, OCCT algorithms cannot work with that curve correctly.
IntStatus_Fail	Algorithm cannot finish correctly.

Flag theIsReqToKeepRLine has been entered only for compatibility with TopOpeBRep package. It shall be deleted after deleting TopOpeBRep.

Member Function Documentation

IntStatus IntPatch_ImpImpIntersection::GetStatus

(

)

const

Returns status.

Standard_Boolean IntPatch_ImpImpIntersection::IsDone

(

)

const

Returns True if the calculus was successful.

Standard_Boolean IntPatch_ImpImpIntersection::IsEmpty

(

)

const

Returns true if the is no intersection.

const Handle< IntPatch_Line >& IntPatch_ImpImpIntersection::Line

(

const Standard_Integer

Index

)

const

Returns the line of range Index. An exception is raised if Index<=0 or Index>NbLine.

Standard_Integer IntPatch_ImpImpIntersection::NbLines

(

)

const

Returns the number of intersection lines.

Standard_Integer IntPatch_ImpImpIntersection::NbPnts

(

)

const

Returns the number of "single" points.

Standard_Boolean IntPatch_ImpImpIntersection::OppositeFaces

(

)

const

Returns True when the TangentFaces returns True and the normal vectors evaluated at a point on the first and the second surface are opposite. The exception DomainError is raised if TangentFaces returns False.

void IntPatch_ImpImpIntersection::Perform	(	const Handle< Adaptor3d_HSurface > &	S1,
		const Handle< Adaptor3d_TopolTool > &	D1,
		const Handle< Adaptor3d_HSurface > &	S2,
		const Handle< Adaptor3d_TopolTool > &	D2,
		const Standard_Real	TolArc,
		const Standard_Real	TolTang,
		const Standard_Boolean	theIsReqToKeepRLine = Standard_False
	)

Flag theIsReqToKeepRLine has been entered only for compatibility with TopOpeBRep package. It shall be deleted after deleting TopOpeBRep. When intersection result returns IntPatch_RLine and another IntPatch_Line (not restriction) we (in case of theIsReqToKeepRLine==TRUE) will always keep both lines even if they are coincided.

const IntPatch_Point& IntPatch_ImpImpIntersection::Point

(

const Standard_Integer

Index

)

const

Returns the point of range Index. An exception is raised if Index<=0 or Index>NbPnt.

Standard_Boolean IntPatch_ImpImpIntersection::TangentFaces

(

)

const

Returns True if the two patches are considered as entirely tangent, i.e every restriction arc of one patch is inside the geometric base of the other patch.
