	BRepMesh_FastDiscret (const Standard_Real defle, const Standard_Real angle, const Bnd_Box &B, const Standard_Boolean withShare=Standard_True, const Standard_Boolean inshape=Standard_False, const Standard_Boolean relative=Standard_False, const Standard_Boolean shapetrigu=Standard_False)
	BRepMesh_FastDiscret (const Standard_Real defle, const TopoDS_Shape &shape, const Bnd_Box &B, const Standard_Real angle, const Standard_Boolean withShare=Standard_True, const Standard_Boolean inshape=Standard_False, const Standard_Boolean relative=Standard_False, const Standard_Boolean shapetrigu=Standard_False)
	if the boolean <relative> is True, the deflection used for the polygonalisation of each edge will be <defle> * Size of Edge. the deflection used for the faces will be the maximum deflection of their edges. if <shapetrigu> is True, the triangulation, if exists with a correct deflection, can be used to re-triangulate the shape. if <inshape> is True, the calculated triangulation will be stored in the shape.
void	Perform (const TopoDS_Shape &shape)
	Build triangulation on the whole shape
void	Add (const TopoDS_Face &face)
	Record a face for further processing.
void	Process (const TopoDS_Face &face) const
	Triangulate a face previously recorded for processing by call to Add(). Can be executed in parallel threads.
void	operator() (const TopoDS_Face &face) const
Standard_Boolean &	InternalVerticesMode ()
	Returns mode defining if internal vertices on faces are taken into consideration or not. If this mode is equal to true that internal vertices on faces are considered during triangulation. Default value is equal to false (old behaviour).
BRepMesh_Status	CurrentFaceStatus () const
Standard_Integer	NbTriangles () const
	Gives the number of built triangles.
const BRepMesh_Triangle &	Triangle (const Standard_Integer Index) const
	Gives the triangle of <Index>.
Standard_Integer	NbEdges () const
	Gives the number of built Edges
const BRepMesh_Edge &	Edge (const Standard_Integer Index) const
	Gives the edge of index <Index>.
Standard_Integer	NbVertices () const
	Gives the number of built Vertices.
const BRepMesh_Vertex &	Vertex (const Standard_Integer Index) const
	Gives the vertex of <Index>.
const gp_Pnt &	Pnt (const Standard_Integer Index) const
	Gives the location3d of the vertex of <Index>.
void	VerticesOfDomain (MeshDS_MapOfInteger &Indices) const
	Gives the list of indices of the vertices
void	EdgesOfDomain (MeshDS_MapOfInteger &Indices) const
	Gives the list of indices of the edges
void	TrianglesOfDomain (MeshDS_MapOfInteger &Indices) const
	Gives the list of indices of the triangles
Standard_Integer	NbPoint3d () const
	Gives the number of different location in 3d space. It is different of the number of vertices if there is more than one surface. Even for one surface, the number can be different if an edge is shared.
const gp_Pnt &	Point3d (const Standard_Integer Index) const
	Gives the 3d space location of the vertex <Index>.
Standard_Real	GetDeflection () const
	returns the deflection value.
Standard_Real	GetAngle () const
	returns the deflection value.
Standard_Boolean	WithShare () const
Standard_Boolean	InShape () const
Standard_Boolean	ShapeTrigu () const
Standard_Boolean	GetFaceAttribute (const TopoDS_Face &face, Handle< BRepMesh_FaceAttribute > &fattrib) const
	returns the face deflection value.
void	RemoveFaceAttribute (const TopoDS_Face &face)
	remove face attribute as useless to free locate memory
const TopTools_DataMapOfShapeReal &	GetMapOfDefEdge () const
