Member Function Documentation

◆ AdjustCurve()

bool ShapeConstruct_Curve::AdjustCurve	(	const occ::handle< Geom_Curve > &	C3D,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const bool	take1 = true,
		const bool	take2 = 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()

bool ShapeConstruct_Curve::AdjustCurve2d	(	const occ::handle< Geom2d_Curve > &	C2D,
		const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2,
		const bool	take1 = true,
		const bool	take2 = 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()

bool ShapeConstruct_Curve::AdjustCurveSegment	(	const occ::handle< Geom_Curve > &	C3D,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const double	U1,
		const double	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]

occ::handle< Geom2d_BSplineCurve > ShapeConstruct_Curve::ConvertToBSpline	(	const occ::handle< Geom2d_Curve > &	C,
		const double	first,
		const double	last,
		const double	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)

◆ ConvertToBSpline() [2/2]

occ::handle< Geom_BSplineCurve > ShapeConstruct_Curve::ConvertToBSpline	(	const occ::handle< Geom_Curve > &	C,
		const double	first,
		const double	last,
		const double	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)

◆ FixKnots() [1/2]

static bool ShapeConstruct_Curve::FixKnots ( NCollection_Array1< double > & knots )

static

Fix bspline knots to ensure that there is enough gap between neighbouring values Returns True if something fixed (by shifting knot)

◆ FixKnots() [2/2]

static bool ShapeConstruct_Curve::FixKnots ( occ::handle< NCollection_HArray1< double > > & knots )
