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 double Tol) |
| Sets tolerance. | |
| void | Compute (const bool Segment) override |
| Calculates points for correction/splitting of the surface. | |
 Public Member Functions inherited from ShapeUpgrade_SplitSurface | |
| ShapeUpgrade_SplitSurface () | |
| Empty constructor. | |
| void | Init (const occ::handle< Geom_Surface > &S) |
| Initializes with single supporting surface. | |
| void | Init (const occ::handle< Geom_Surface > &S, const double UFirst, const double ULast, const double VFirst, const double VLast, const double theArea=0.) |
| Initializes with single supporting surface with bounding parameters. | |
| void | SetUSplitValues (const occ::handle< NCollection_HSequence< double > > &UValues) |
| Sets U parameters where splitting has to be done. | |
| void | SetVSplitValues (const occ::handle< NCollection_HSequence< double > > &VValues) |
| Sets V parameters where splitting has to be done. | |
| virtual void | Build (const bool 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 bool Segment=true) |
| Performs correction/splitting of the surface. First defines splitting values by method Compute(), then calls method Build(). | |
| const occ::handle< NCollection_HSequence< double > > & | USplitValues () const |
| returns all the U splitting values including the First and Last parameters of the input surface | |
| const occ::handle< NCollection_HSequence< double > > & | VSplitValues () const |
| returns all the splitting V values including the First and Last parameters of the input surface | |
| bool | 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 occ::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_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | 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. | |
| bool | IsKind (const char *const 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. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
