	This method is called to build presentation of custom elements (they have MeshVS_ET_0D type). IDs is set of numeric identificators of elements for custom building. IDsToExclude is set of IDs to exclude from processing. If some entity has been excluded, it is not processed by other builders. DisplayMode is numeric constant describing display mode (see MeshVS_DisplayModeFlags.hxx).

	Returns priority; as priority bigger, as soon builder will be called.

	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.

	Constructor Parent is pointer to MeshVS_Mesh object Flags is set of display modes corresponding to this builder DS is data source object, from which builder will pick geometry and topological information Id is numeric identificator of builder. You must set it to positive integer, but if you set it to -1, constructor will select the smallest integer, not occupied by other builders Priority is numerical priority constant.
