飞机座舱段机身曲面造型智能化设计的研究

Study of intelligent design on the fuselage model surface of the cockpit section

应用双三次B样条曲面理论建立了飞机座舱段机身曲面的数学模型 ,并利用C语言编程 ,实现了通过型值点数据反算出控制顶点 ,再经过理论外形计算和三维图形变换 。

This thesis introduces the whole procedure in which the model of a sophisticated surface, the fuselage surface of the cockpit section was completed by applying the theory of the bi-cubic B spine surface.The intelligent design is come true with the help of C language , getting a group of grip point data , and then inverse operating the controlling vertex basing on the grip point , through the 3D graphic transformation , the whole 3D sophisticated surface would be drawn out.
