ShapeUpgrade_SplitSurfaceContinuity Class Reference

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. More...

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.
 
- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (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_TransientThis () 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.
