    Public Member Functions

     Aspect_CircularGrid (const double aRadiusStep, const int aDivisionNumber, const double XOrigin=0, const double anYOrigin=0, const double aRotationAngle=0)
     creates a new grid. By default this grid is not active.
    void SetRadiusStep (const double aStep)
     defines the x step of the grid.
    void SetDivisionNumber (const int aNumber)
     defines the step of the grid.
    void SetGridValues (const double XOrigin, const double YOrigin, const double RadiusStep, const int DivisionNumber, const double RotationAngle)
    void Compute (const double X, const double Y, double &gridX, double &gridY) const override
     returns the point of the grid the closest to the point X,Y
    double RadiusStep () const
     returns the x step of the grid.
    int DivisionNumber () const
     returns the x step of the grid.
    void SetRadius (const double theRadius)
     Set the circular grid radius (plane-local units). 0.0 (default) means unbounded - the shader draws the grid to the horizon.
    double Radius () const
     Return the bounded radius. 0.0 means unbounded.
    void SetZOffset (const double theOffset)
     Set signed offset along the plane normal for display only; snap math stays on the plane. Use a small negative value to avoid z-fighting with coplanar geometry.
    double ZOffset () const
     Return the display-time Z-offset along the plane normal.
    void SetArcRange (const double theStart, const double theEnd)
     Restrict the grid to an angular wedge, walking counter-clockwise from theStart to theEnd (radians, measured from the rotated plane X axis). Setting both values equal (e.g. both 0.0) returns to full-circle rendering - the sentinel used for unbounded.
    double AngleStart () const
     Return the arc start angle (radians). Meaningful only when IsArc() is true.
    double AngleEnd () const
     Return the arc end angle (radians). Meaningful only when IsArc() is true.
    bool IsArc () const
     Return TRUE when the grid is restricted to an angular wedge.
    void Init () override
    void DumpJson (Standard_OStream &theOStream, int theDepth=-1) const override
     Dumps the content of me into the stream.
    Public Member Functions inherited from Aspect_Grid
    void SetXOrigin (const double anOrigin)
     defines the x Origin of the grid.
    void SetYOrigin (const double anOrigin)

     Change the colors of the grid.
    void Hit (const double X, const double Y, double &gridX, double &gridY) const
     returns the point of the grid the closest to the point X,Y if the grid is active. If the grid is not active returns X,Y.
    void Activate ()
     activates the grid. The Hit method will return gridx and gridx computed according to the steps of the grid.
    void Deactivate ()
     deactivates the grid. The hit method will return gridx and gridx as the enter value X & Y.
    double XOrigin () const
     returns the x Origin of the grid.
    double YOrigin () const
     returns the x Origin of the grid.
    double RotationAngle () const

     Returns the colors of the grid.
    void SetDrawMode (const Aspect_GridDrawMode aDrawMode)
     Change the grid aspect.
    Aspect_GridDrawMode DrawMode () const
     Returns the grid aspect.
    virtual void Display ()=0
     Display the grid at screen.
    virtual void Erase () const =0
     Erase the grid from screen.
    virtual bool IsDisplayed () const =0
     Returns TRUE when the grid is displayed at screen.
    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 ()=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_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.
    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.

    Additional Inherited Members
