Detailed Description

Branch is a set of MA edges enclosed between branch points and/or MA ends.

It's main feature is to return two BoundaryPoint's per a point on it. Points on a Branch are defined by [0,1] parameter

bool SMESH_MAT2d::Branch::getBoundaryPoints	(	double	param,
		BoundaryPoint &	bp1,
		BoundaryPoint &	bp2
	)		const

Returns points on two EDGEs, equidistant from a given point of this Branch.

Parameters

[in]	param	- [0;1] normalized param on the Branch
[out]	bp1	- BoundaryPoint on EDGE with a lower index
[out]	bp2	- BoundaryPoint on EDGE with a higher index

Returns: bool - true if the BoundaryPoint's found

Parameters

[in]	iMAEdge	- index of a MA edge within this Branch
[in]	maEdgeParam	- [0;1] normalized param on the iMAEdge
[out]	bp1	- BoundaryPoint on EDGE with a lower index
[out]	bp2	- BoundaryPoint on EDGE with a higher index

	)		const

Return indices of opposite parts of EDGEs equidistant from this branch.

Parameters

[out]	edgeIDs1	- EDGE index opposite to the edgeIDs2[i]-th EDGE
[out]	edgeIDs2	- EDGE index opposite to the edgeIDs1[i]-th EDGE
[out]	divPoints	- BranchPoint's located between two successive unique pairs of EDGE indices. A divPoints[i] can separate e.g. two following pairs of EDGE indices < 0, 2 > and < 0, 1 >. Number of divPoints is one less than number of edgeIDs
