Detailed Description

Adjusts curve to have start and end points at the given points (currently works on lines and B-Splines only)

Member Function Documentation

◆ AdjustCurve()

Standard_Boolean ShapeConstruct_Curve::AdjustCurve	(	const Handle< Geom_Curve > &	C3D,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const Standard_Boolean	take1 = `Standard_True`,
		const Standard_Boolean	take2 = `Standard_True`
	)		const

Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines, returns True in this case, else returns False. For line considers both bounding points, for B-Splines only specified.

Warning : Does not check if curve should be reversed

◆ AdjustCurve2d()

Standard_Boolean ShapeConstruct_Curve::AdjustCurve2d	(	const Handle< Geom2d_Curve > &	C2D,
		const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2,
		const Standard_Boolean	take1 = `Standard_True`,
		const Standard_Boolean	take2 = `Standard_True`
	)		const

Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines, returns True in this case, else returns False.

For line considers both bounding points, for B-Splines only specified.

Warning : Does not check if curve should be reversed

◆ AdjustCurveSegment()

Standard_Boolean ShapeConstruct_Curve::AdjustCurveSegment	(	const Handle< Geom_Curve > &	C3D,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const Standard_Real	U1,
		const Standard_Real	U2
	)		const

Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines.

For lines works as previous method, B-Splines are segmented at the given values and then are adjusted to the points.

◆ ConvertToBSpline() [1/2]

Handle< Geom_BSplineCurve > ShapeConstruct_Curve::ConvertToBSpline	(	const Handle< Geom_Curve > &	C,
		const Standard_Real	first,
		const Standard_Real	last,
		const Standard_Real	prec
	)		const

Converts a curve of any type (only part from first to last) to bspline. The method of conversion depends on the type of original curve: BSpline -> C.Segment(first,last) Bezier and Line -> GeomConvert::CurveToBSplineCurve(C).Segment(first,last) Conic and Other -> Approx_Curve3d(C[first,last],prec,C1,9,1000)

◆ ConvertToBSpline() [2/2]

Handle< Geom2d_BSplineCurve > ShapeConstruct_Curve::ConvertToBSpline	(	const Handle< Geom2d_Curve > &	C,
		const Standard_Real	first,
		const Standard_Real	last,
		const Standard_Real	prec
	)		const

Converts a curve of any type (only part from first to last) to bspline. The method of conversion depends on the type of original curve: BSpline -> C.Segment(first,last) Bezier and Line -> GeomConvert::CurveToBSplineCurve(C).Segment(first,last) Conic and Other -> Approx_Curve2d(C[first,last],prec,C1,9,1000)
