摘要
本文以组成船体型线单元曲线的不同特点,建立了相应的描述函数,并经加权合成后,成为生成船体横剖线的参数调和方程。同时利用B样条函数的连接和局部修改功能,把型线生成,图像显示,人机交互,曲线修改和光顺性判别互为一体,形成了独特的方法,具有良好的控制和人机交互设计型线的功效。
Based on the different characteristics of elementary curves generating the ship form, the author presents in this paper the establishment of relevant portrait function. After composing by weighting, the parameter harmonic function of ship cross-sectional curve is then established. By making use of the function of connection and local modification of B spline, the generation of lines, graphic display, man-machive interface, curve modification and discriminant for fairness are bound together and formed into a unigue method, which has a good function of control and designing lines with manmachine interaction.
