	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.

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

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().

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.

	Returns a true value if this is an instance of TypeName.

	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.

Constructor & Destructor Documentation

◆ ShapeUpgrade_SplitSurface()

ShapeUpgrade_SplitSurface::ShapeUpgrade_SplitSurface ( )

Empty constructor.

Member Function Documentation

◆ Build()

virtual void ShapeUpgrade_SplitSurface::Build ( const Standard_Boolean Segment )

virtual

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.

Reimplemented in ShapeUpgrade_ConvertSurfaceToBezierBasis.

◆ Compute()

virtual void ShapeUpgrade_SplitSurface::Compute ( const Standard_Boolean Segment = Standard_True )

virtual

Calculates points for correction/splitting of the surface.

Reimplemented in ShapeUpgrade_ConvertSurfaceToBezierBasis, ShapeUpgrade_SplitSurfaceAngle, ShapeUpgrade_SplitSurfaceArea, and ShapeUpgrade_SplitSurfaceContinuity.

◆ Init() [1/2]

void ShapeUpgrade_SplitSurface::Init ( const Handle< Geom_Surface > & S )

Initializes with single supporting surface.

◆ Init() [2/2]

void ShapeUpgrade_SplitSurface::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.

◆ Perform()

void ShapeUpgrade_SplitSurface::Perform ( const Standard_Boolean Segment = Standard_True )

Performs correction/splitting of the surface. First defines splitting values by method Compute(), then calls method Build().

◆ ResSurfaces()

const Handle< ShapeExtend_CompositeSurface > & ShapeUpgrade_SplitSurface::ResSurfaces ( ) const

Returns obtained surfaces after splitting as CompositeSurface.

◆ SetUSplitValues()

void ShapeUpgrade_SplitSurface::SetUSplitValues ( const Handle< TColStd_HSequenceOfReal > & UValues )

Sets U parameters where splitting has to be done.

◆ SetVSplitValues()

void ShapeUpgrade_SplitSurface::SetVSplitValues ( const Handle< TColStd_HSequenceOfReal > & VValues )

Sets V parameters where splitting has to be done.

◆ Status()

Standard_Boolean ShapeUpgrade_SplitSurface::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.

◆ USplitValues()

const Handle< TColStd_HSequenceOfReal > & ShapeUpgrade_SplitSurface::USplitValues ( ) const

returns all the U splitting values including the First and Last parameters of the input surface

◆ VSplitValues()

const Handle< TColStd_HSequenceOfReal > & ShapeUpgrade_SplitSurface::VSplitValues ( ) const

returns all the splitting V values including the First and Last parameters of the input surface
