At points between the spline curves, the geometry is interpolated using spline interpolation functions, thus the body geometry is defined continuously all over the surface. In this paper, a method is shown to generate a spline net based on the offset data given at discrete points. The method is an extension of a grid generation method called the implicit geometrical method. The smoothing, clustering, and orthogonality requirements are imposed, and the spline net is generated to satisfy those requirements with suitable balance. In the first half of the paper, it is shown that the fourth-differencing operator used as the smoothing operator has characteristics quite similar to cubic Ferguson splines. In the second half, a spline net generated on a ship hull form is shown as an example. The generated spline net satisfies not only the imposed requirements, but also the constraint that the net passes through the offset spline points.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
