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.

bool MbCurveEdge::ChangeCarrierBorne ( const MbSurface item,

◆ IsConvex()

ThreeStates MbCurveEdge::IsConvex ( double  angleEps = EXTENT_EPSILON,
const MbRect1D tRange = NULL 
) const

Is an edge convex?

Is an edge convex by its middle parameter (or middle parameter of input range)? The calculation is correct for edges which do not change a convexity. Returns ts_neutral for smooth edges.

◆ CopyReadyMutable()

bool MbCurveEdge::CopyReadyMutable ( const MbCurveEdge e)

Copy from the copy ready estimates which were not calculated in the original.

Warning
Attention: a check of identity between a copy and an original is not performed for the time saving!

◆ GetMoveVector()

bool MbCurveEdge::GetMoveVector ( const MbSurface surf,
bool  faceSene,
bool  orient,
MbVector to 
) const

Calculate two-dimensional vector of two-dimensional curve shift.

Calculate two-dimensional vector of two-dimensional curve shift.

◆ IsCurveOneOnFacePlus()

int MbCurveEdge::IsCurveOneOnFacePlus ( ) const

Where surfaces (faces) intersection curves lie:
curveOne on facePlus, curveTwo on faceMinus => +1
curveOne on faceMinus, curveTwo on facePlus => -1
otherwise => 0

◆ CuttingEdge() [1/2]

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)
[in]surface- For tolerant curve it is required to specify a surface which contain a curve a parameter belongs to.
Returns
Returns a cut edge.

◆ TruncateEdge()

bool MbCurveEdge::TruncateEdge ( double &  t,
bool  beginCutting,
const MbSurface surface 
)

Truncate an edge by the parameter of its curve.

If beginCutting == true - then the starting part of an edge is cut. If beginCutting == false - then the ending part of an edge is cut.

Parameters
[in]t- Parameter of intersection curve of edge to truncate.
[in]beginCutting- The edge will keep a beginning piece (false) or the edge will keep an end piece (true).
[in]surface- For tolerant curve it is required to specify a surface which contain a curve a parameter belongs to.
Returns
Returns true if the edge was truncated, otherwise returns false.

◆ CuttingEdge() [2/2]

bool MbCurveEdge::CuttingEdge ( SArray< double > &  params,
bool  beginSafe,
double  eps,
const MbSurface surface,
RPArray< MbCurveEdge > &  edges 
)

Split the edge by the curve parameters into several pieces.

. If beginSafe == true then the edge saves its starting piece, If beginSafe == false then the edge saves its ending piece. According to the parameter 'eps' drop out value in the container 'params', coinciding with each other and with the initial and final parameters of the intersection curve. The parameter 'surface' plays a role only for tolerant edge. The container 'edges' contains cut parts. The cut parts will be embedded in the loops of adjacent faces.

Parameters
[in]params- Parameters 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)
[in]eps- Precision matching options of parameters to split,
[in]surface- For tolerant curve it is required to specify a surface of face which contain a curve parameters belongs to.
[out]edges- The container of cut parts.
Returns
Returns true, if the edge was cut.

◆ ConvexoConcaveCutting()

bool MbCurveEdge::ConvexoConcaveCutting ( RPArray< MbCurveEdge > &  edges)

Split the edge by points where the convexity changes.

Split the edge by points where the convexity changes. The container 'edges' contains cut parts of edge. The cut parts will be embedded in the loops of adjacent faces.

Parameters

Returns
Returns true, if the edge was cut.

◆ ProlongEdge()

Prolong an edge.

Continue the intersection curve of edge by the parameter t, lying outside of the curve.

Parameters

bool  begin1,
bool  begin2,
VERSION  version,
bool  addParentNamesAttributes 
)

Merging of two connected edges.

Merging of two connected edges:
Before the call AddRef should be done on the edges, since one of the edges may be deleted, and after the call and using the edges Release should be done on them.

Parameters
