buildC3dOnIsoLine()

bool Approx_CurveOnSurface::buildC3dOnIsoLine ( const occ::handle< Adaptor2d_Curve2d > & theC2D, const bool theIsU, const double theParam, const bool theIsForward )

protected

Builds 3D curve for a isoline. This method takes corresponding isoline from the input surface.

Parameters

theC2D	Trimmed curve to be approximated.
theIsU	Flag indicating that line is u const.
theParam	Line parameter.
theIsForward	Flag indicating forward parameterization on a isoline.

Returns

true when 3d curve is built and false otherwise.

Checks whether the 2d curve is a isoline. It can be represented by b-spline, bezier, or geometric line. This line should have natural parameterization.

Parameters

theC2D	Trimmed curve to be checked.
theIsU	Flag indicating that line is u const.
theParam	Line parameter.
theIsForward	Flag indicating forward parameterization on a isoline.

Returns

		const int	theMaxDegree,
		const GeomAbs_Shape	theContinuity,
		const bool	theOnly3d = false,
		const bool	theOnly2d = false )

Constructs the 3d curve. Input parameters are ignored when the input curve is U-isoline or V-isoline.

Parameters

theMaxSegments	Maximal number of segments in the resulting spline.
theMaxDegree	Maximal degree of the result.
