Public Member Functions
	ShapeUpgrade_SplitSurfaceContinuity ()
	Empty constructor.

void	SetCriterion (const GeomAbs_Shape Criterion)
	Sets criterion for splitting.

void	SetTolerance (const Standard_Real Tol)
	Sets tolerance.

virtual void	Compute (const Standard_Boolean Segment) override
	Calculates points for correction/splitting of the surface.

Public Member Functions inherited from ShapeUpgrade_SplitSurface
	ShapeUpgrade_SplitSurface ()
	Empty constructor.

void	Init (const Handle< Geom_Surface > &S)
	Initializes with single supporting surface.

void	Init (const Handle< Geom_Surface > &S, const Standard_Real UFirst, const Standard_Real ULast, const Standard_Real VFirst, const Standard_Real VLast, const Standard_Real theArea=0.)
	Initializes with single supporting surface with bounding parameters.

void	SetUSplitValues (const Handle< TColStd_HSequenceOfReal > &UValues)
	Sets U parameters where splitting has to be done.

void	SetVSplitValues (const Handle< TColStd_HSequenceOfReal > &VValues)
	Sets V parameters where splitting has to be done.

virtual void	Build (const Standard_Boolean Segment)
	Performs splitting of the supporting surface. If resulting surface is B-Spline and Segment is True, the result is composed with segments of the surface bounded by the U and V SplitValues (method Geom_BSplineSurface::Segment is used). If Segment is False, the result is composed with Geom_RectangularTrimmedSurface all based on the same complete surface. Fields myNbResultingRow and myNbResultingCol must be set to specify the size of resulting grid of surfaces.

void	Perform (const Standard_Boolean Segment=Standard_True)
	Performs correction/splitting of the surface. First defines splitting values by method Compute(), then calls method Build().

const Handle< TColStd_HSequenceOfReal > &	USplitValues () const
	returns all the U splitting values including the First and Last parameters of the input surface

const Handle< TColStd_HSequenceOfReal > &	VSplitValues () const
	returns all the splitting V values including the First and Last parameters of the input surface

Standard_Boolean	Status (const ShapeExtend_Status status) const
	Returns the status OK - no splitting is needed DONE1 - splitting required and gives more than one patch DONE2 - splitting is required, but gives only single patch (initial) DONE3 - geometric form of the surface or parametrisation is modified.

const Handle< ShapeExtend_CompositeSurface > &	ResSurfaces () const
	Returns obtained surfaces after splitting as CompositeSurface.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.

Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.

virtual void	Delete () const
	Memory deallocator for transient classes.

Detailed Description

Splits a Surface with a continuity criterion. At the present moment C1 criterion is used only. This tool works with tolerance. If C0 surface can be corrected at a knot with given tolerance then the surface is corrected, otherwise it is spltted at that knot.
