            <function>gluGetNurbsProperty</function> retrieves properties stored in a NURBS object. These
            properties affect the way that NURBS curves and surfaces
            are rendered. See the 
            <citerefentry><refentrytitle>gluNurbsProperty</refentrytitle></citerefentry> reference page for information about what the 
            properties are and what they do.
