Detailed Description

This class can detect vertices in a face that can
be considered useless and then perform the fuse of
the edges and remove the useless vertices. By
useles vertices, we mean :

• vertices that have exactly two connex edges
  
• the edges connex to the vertex must have
  exactly the same 2 connex faces .
  
• The edges connex to the vertex must have the
  same geometric support.
  

Constructor & Destructor Documentation

BRepLib_FuseEdges::BRepLib_FuseEdges	(	const TopoDS_Shape &	theShape,
		const Standard_Boolean	PerformNow = Standard_False
	)

Initialise members and build construction of map
of ancestors.

Member Function Documentation

void BRepLib_FuseEdges::AvoidEdges

(

const TopTools_IndexedMapOfShape &

theMapEdg

)

set edges to avoid being fused

void BRepLib_FuseEdges::Edges

(

TopTools_DataMapOfIntegerListOfShape &

theMapLstEdg

)

returns all the list of edges to be fused
each list of the map represent a set of connex edges
that can be fused.

void BRepLib_FuseEdges::Faces

(

TopTools_DataMapOfShapeShape &

theMapFac

)

returns the map of modified faces.

const Standard_Integer BRepLib_FuseEdges::NbVertices

(

)

returns the number of vertices candidate to be removed

void BRepLib_FuseEdges::Perform

(

)

Using map of list of connex edges, fuse each list to
one edge and then update myShape

void BRepLib_FuseEdges::ResultEdges

(

TopTools_DataMapOfIntegerShape &

theMapEdg

)

 returns all the fused edges. each integer entry in <br>
      the   map  corresponds  to  the  integer   in the <br>
      DataMapOfIntegerListOfShape  we    get in  method <br>
     Edges.   That is to say, to  the list  of edges in <br>
     theMapLstEdg(i) corresponds the resulting edge theMapEdge(i) <br>

void BRepLib_FuseEdges::SetConcatBSpl

(

const Standard_Boolean

theConcatBSpl = Standard_True

)

set mode to enable concatenation G1 BSpline edges in one <br>

End Modified by IFV 19.04.07

TopoDS_Shape& BRepLib_FuseEdges::Shape

(

)

returns myShape modified with the list of internal
edges removed from it.
