Unformatted text preview: ror. Figure 3: Representation of a paraboloid used to generate the dataset Moreover, each dataset was randomly oriented into the coordinate system. The datasets 6 of the truncated cone and the dataset 5 of the paraboloid are reported in Appendix. Figures 4 and 5, that was taken from Mathematica®, show the representation of the two step of the optimization process. The obtained results are higher than the value of the form tolerance in all cases, since the adopted approach is based on least squares principle, even if they are enough close to the form tolerance.
