Detailed Description

Face edge.

A face edge is a curve of surfaces intersection MbSurfaceIntersectionCurve with direction. In contrast to an edge MbEdge an edge MbCurveEdge describes not just a curve, but a smooth piece of connection between two faces or a smooth piece of face boundary.
A face edge is used to describe a piece of connection between two faces or a piece of face boundary.
If an edge describes a piece of connection between two faces then the both pointers to faces are not null.
An edge describing a piece of connection of a cyclic closed faces with itself is called seam.
In the last case pointers to the left face and to the right face are the same.
If an edge describes a piece of face boundary then the pointer to the left face or the pointer to the right face equals null.
An edge describing a contracted to a point piece of face boundary is called a pole edge.
If an edge describes a piece of face boundary then a curve of surfaces intersection is boundary too, i.e. it consists of two equal curves on surface.
An edge starts and ends in vertices MbVertex. If a curve of an edge is cyclic closed, then an edge starts and ends at the same vertex.

CuttingEdge() [1/3]

MbCurveEdge* MbCurveEdge::CuttingEdge	(	double	t,
		bool	beginSafe,
		const MbSurface *	surface
	)

Split an edge by the parameter of its curve.

If beginSafe == true then the edge saves its starting piece, the spit edge will save its start vertex and will end at the vertex breakVertex, the new edge newEdge will start at the vertex breakVertex and will end at the ex-end vertex of the spit edge If beginSafe == false then the edge saves its ending piece, the spit edge will save its end vertex and will start at the vertex breakVertex, the new edge newEdge will start at the start vertex of the spit edge and will end at the vertex breakVertex.
The parameter 'surface' plays a role only for tolerant edge. The new edge will be embedded in the loops of adjacent faces.

Parameters

[in]	t	- Parameter of intersection curve of edge to split,
[in]	beginSafe	- The edge will keep a beginning piece (true) or the edge will keep an end piece (false)
