Member Function Documentation

bool SMESH_MAT2d::Boundary::getBranchPoint	(	const std::size_t	iEdge,
		double	u,
		BranchPoint &	p
	)		const

Returns a BranchPoint corresponding to a given point on a geom EDGE.

Parameters

[in]	iEdge	- index of geom EDGE within a vector passed at MA construction
[in]	u	- parameter of the point on EDGE curve
[out]	p	- the found BranchPoint

Returns

bool - is OK

bool SMESH_MAT2d::Boundary::getBranchPoint	(	const BoundaryPoint &	bp,
		BranchPoint &	p
	)		const

Returns a BranchPoint corresponding to a given BoundaryPoint on a geom EDGE.

Parameters

[in]	bp	- the BoundaryPoint
[out]	p	- the found BranchPoint

Returns

bool - is OK

bool SMESH_MAT2d::Boundary::getPoint	(	std::size_t	iEdge,
		std::size_t	iSeg,
		double	u,
		BoundaryPoint &	bp
	)		const

Returns a boundary point on a given EDGE.

Parameters
