    Public Member Functions

     BVH_SpatialMedianBuilder (const int theLeafNodeSize=BVH_Constants_LeafNodeSizeDefault, const int theMaxTreeDepth=BVH_Constants_MaxTreeDepth, const bool theToUseMainAxis=false)
     Creates spatial median split builder.
     ~BVH_SpatialMedianBuilder () override=default
     Releases resources of spatial median split builder.
    Public Member Functions inherited from BVH_BinnedBuilder< T, N, 2 >
     BVH_BinnedBuilder (const int theLeafNodeSize=BVH_Constants_LeafNodeSizeDefault, const int theMaxTreeDepth=BVH_Constants_MaxTreeDepth, const bool theDoMainSplits=false, const int theNumOfThreads=1)
     Creates binned SAH BVH builder.
     ~BVH_BinnedBuilder () override=default
     Releases resources of binned SAH BVH builder.
    Public Member Functions inherited from BVH_QueueBuilder< T, N >
     BVH_QueueBuilder (const int theLeafNodeSize, const int theMaxTreeDepth, const int theNumOfThreads=1)
     Creates new BVH queue based builder.
     ~BVH_QueueBuilder () override=default
     Releases resources of BVH queue based builder.
    void Build (BVH_Set< T, N > *theSet, BVH_Tree< T, N > *theBVH, const BVH_Box< T, N > &theBox) const override
     Builds BVH using specific algorithm.
    Public Member Functions inherited from BVH_BuilderTransient
    int MaxTreeDepth () const
     Returns the maximum depth of constructed BVH.
    int LeafNodeSize () const
     Returns the maximum number of sub-elements in the leaf.
    bool IsParallel () const
     Returns parallel flag.
    void SetParallel (const bool isParallel)
     Set parallel flag controlling possibility of parallel execution.
    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.
