| Abstract | B-spline curves and surfaces and their suitability for ship hull surface definition are discussed. A comparison with other curve and surface definition methods, e.g., cubic splines, Bézier curves, parabolic blending is given. Their use both for ab initio curve and surface generation and for fitting existing offset data is discussed. Comparisons of the data storage requirements are made. The utilization of these concepts in an interactive design program implemented on an Evans and Sutherland Picture System supported by a PDP 11/45 and a Xynetics Model 1200 flat plotter are discussed. Initial efforts in generating numerical control tapes from the resulting data base and the manufacture of towing tank models are discussed. A demonstration of this program and the model manufacturing technique will be given. |
