Public Member Functions | |
| BVH_SweepPlaneBuilder (const int theLeafNodeSize=BVH_Constants_LeafNodeSizeDefault, const int theMaxTreeDepth=BVH_Constants_MaxTreeDepth, const int theNumOfThreads=1) | |
| Creates sweep plane SAH BVH builder. | |
| ~BVH_SweepPlaneBuilder () override=default | |
| Releases resources of sweep plane 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_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. | |
Protected Member Functions | |
| BVH_QueueBuilder< T, N >::BVH_ChildNodes | buildNode (BVH_Set< T, N > *theSet, BVH_Tree< T, N > *theBVH, const int theNode) const override |

| Protected Member Functions inherited from BVH_QueueBuilder< T, N > | |
