	Builds presentation of certain type of data. Prs is presentation object which this method constructs. IDs is set of numeric identificators forming object appearance. IDsToExclude is set of IDs to exclude from processing. If some entity has been excluded, it is not processed by other builders. IsElement indicates, IDs is identificators of nodes or elements. DisplayMode is numeric constant describing display mode (see MeshVS_DisplayModeFlags.hxx)

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.
