摘 要
汽车工业的迅猛发展，给汽车的设计提出 了新的要求，汽车消费趋于大众化，根据人们不同的用途和审美选择也要求车型要多种多样，本人针对这1趋势，基于计算机图形学的原理，利用数值计算方法的曲线拟合来尝试轿车外形的设计。
本人根据这些原理设计了1种用于设计轿车外形的程序和方法，此方法在理论上可以设计出无穷多种形状，因而可以为用户提供充分的选择余地。在计算机上实现了轿车外形设计的多样化，并且读者可以自行设计。

Abstract
The automobile industry swift and violent development, proposed for the automobile design the new request, the automobile expends tends to the popularity, also requests the vehicle type according to the people different use and the esthetic choice to have many and varied, myself in view of this tendency, based on the computer graphics principle, design.
Myself which attempted the passenger vehicle contour using the value computational method curve fitting according to these principles to design one kind to use in to design the passenger vehicle contour the procedure and the method. This method in theoretically may design the infinite many kinds of shapes, thus may provide the full choice leeway for the user. Realized the vehicle type on the computer to spanersity, and the reader was allowed independently to design.
Key word: Value computation; computer graphics, C# Programming
前 言
曲线拟合在工程领域，如在汽车车身设计、飞机表面设计以及船壳设计中有着极为广泛的应用。在我们的专业课程《数值计算方法》和《计算机图形》中介绍了插值和曲线拟合，由于我对机械设计和轿车都很有兴趣，所以我的设计课题选择了《基于数值计算的轿车图形设计》，采用数值方法，运用C语言设计程序，来实现1个简单的轿车外壳设计，程序设计的目标是能够利用拟合算法拟合出轿车的外壳曲线，并提供视图界面，能够让读者看到整体的图形，体会图形的外观，然后根据自己的审美观点来取舍或更改图形的形状，直到得到自己满意的图形曲线。
