The progressive iteration approximation property (PIA) permits applying tools of CAGD to the interpolation of curves and surfaces. Convergence rates of PIA for bases of different spaces are analyzed and compared, including tables of rate of convergence and figures. In the rational case, the importance of an adequate choice of the weights and of an adequate evaluation algorithm is shown. Finally, a new approach to the PIA is introduced.
