To demonstrate the power of the surface capabilities of Fairway the design process of a frigate-like hull form will be discussed.
- In the first figure a set of 11 curves is shown. These curves have been drawn interactively on screen, with the aid of the NURBS curve control points. Because each curve has its own parametrization, the number of control points per curve can vary. So for each curve we have used a minimum number of control points (neccesary to obtain the desired curve shape), which makes additonal curve fairing obsolete.
- Subsequently surface patches were generated, which derive their curved shape from the shape of the curves in the vicinity. In order to check the shape of the generated cross sections, the additional sections were projected upon these patches, as shown in the body plan of the second figure.
- Finally, waterlines and buttocks have been generated by Fairway, resulting in the complete hull design of the third figure. The last figure shows a rendered view of the complete surface. On a Pentium 300 MHz the creation of all the additional curves took 25 seconds.
