Static Public Member Functions
static void	Precision (const Standard_Real P)
	Sets the default precision. The current Precision is returned.
static Standard_Real	Precision ()
	Returns the default precision.
static void	Plane (const Handle< Geom_Plane > &P)
	Sets the current plane to P.
static const Handle_Geom_Plane &	Plane ()
	Returns the current plane.
static Standard_Boolean	CheckSameRange (const TopoDS_Edge &E, const Standard_Real Confusion=1.0e-12)
	checks if the Edge is same range IGNORING the same range flag of the edge Confusion argument is to compare real numbers idenpendently of any model space tolerance
static void	SameRange (const TopoDS_Edge &E, const Standard_Real Tolerance=1.0e-5)
	will make all the curve representation have the same range domain for the parameters. This will IGNORE the same range flag value to proceed. If there is a 3D curve there it will the range of that curve. If not the first curve representation encountered in the list will give its range to the all the other curves.
static Standard_Boolean	BuildCurve3d (const TopoDS_Edge &E, const Standard_Real Tolerance=1.0e-5, const GeomAbs_Shape Continuity=GeomAbs_C1, const Standard_Integer MaxDegree=14, const Standard_Integer MaxSegment=0)
	Computes the 3d curve for the edge <E> if it does not exist. Returns True if the curve was computed or existed. Returns False if there is no planar pcurve. <MaxSegment> >= 30 in approximation
static Standard_Boolean	BuildCurves3d (const TopoDS_Shape &S, const Standard_Real Tolerance, const GeomAbs_Shape Continuity=GeomAbs_C1, const Standard_Integer MaxDegree=14, const Standard_Integer MaxSegment=0)
	Computes the 3d curves for all the edges of <S> return False if one of the computation failed. <MaxSegment> >= 30 in approximation
static Standard_Boolean	BuildCurves3d (const TopoDS_Shape &S)
	Computes the 3d curves for all the edges of <S> return False if one of the computation failed.
static Standard_Boolean	UpdateEdgeTol (const TopoDS_Edge &E, const Standard_Real MinToleranceRequest, const Standard_Real MaxToleranceToCheck)
static Standard_Boolean	UpdateEdgeTolerance (const TopoDS_Shape &S, const Standard_Real MinToleranceRequest, const Standard_Real MaxToleranceToCheck)
static void	SameParameter (const TopoDS_Edge &E, const Standard_Real Tolerance=1.0e-5)
	Computes new 2d curve(s) for the edge <E> to have the same parameter as the 3d curve. The algorithm is not done if the flag SameParameter was True on the Edge.
static void	SameParameter (const TopoDS_Shape &S, const Standard_Real Tolerance=1.0e-5, const Standard_Boolean forced=Standard_False)
	Computes new 2d curve(s) for all the edges of <S> to have the same parameter as the 3d curve. The algorithm is not done if the flag SameParameter was True on an Edge.
static void	UpdateTolerances (const TopoDS_Shape &S, const Standard_Boolean verifyFaceTolerance=Standard_False)
	Replaces tolerance of FACE EDGE VERTEX by the tolerance Max of their connected handling shapes. It is not necessary to use this call after SameParameter. (called in)
static Standard_Boolean	OrientClosedSolid (TopoDS_Solid &solid)
static void	EncodeRegularity (const TopoDS_Shape &S, const Standard_Real TolAng=1.0e-10)
	Encodes the Regularity of edges on a Shape. Warning: <TolAng> is an angular tolerance, expressed in Rad. Warning: If the edges's regularity are coded before, nothing is done.
static void	EncodeRegularity (TopoDS_Edge &S, const TopoDS_Face &F1, const TopoDS_Face &F2, const Standard_Real TolAng=1.0e-10)
	Encodes the Regularity beetween <F1> and <F2> by <E> Warning: <TolAng> is an angular tolerance, expressed in Rad. Warning: If the edge's regularity is coded before, nothing is done.
static void	SortFaces (const TopoDS_Shape &S, TopTools_ListOfShape &LF)
	Sorts in LF the Faces of S on the complexity of their surfaces (Plane,Cylinder,Cone,Sphere,Torus,other)
static void	ReverseSortFaces (const TopoDS_Shape &S, TopTools_ListOfShape &LF)
	Sorts in LF the Faces of S on the reverse complexity of their surfaces (other,Torus,Sphere,Cone,Cylinder,Plane)
