摘要: 当回转曲面上测地线两端点边界条件一定时,根据Clairant 定理设计一种形、数、 计算机结合的方法求解测地线。避开传统的用偏微分方程组求解的抽象性和复杂性,基于作 图过程建立对应数学模型,最终由计算机绘制测地线。该方法适合于回转曲面,具有形象直 观、精度可控、稳定可靠的优点。

Abstract: When the boundary conditions of the two ends of the geodesic lines on the revolving surface are given, according to the Clairant theorem, a kind of shape, number and computer combination method is designed. To avoid the abstraction and complexity of the traditional solution of partial differential equations, the corresponding mathematical model based on the mapping process is established, and finally the geodesic line is drawn. The proposed method is suitable for the revolving surface, which possesses the advantages of visual image, controllable precision, stable and reliable.
Key words: revolving surface, geodesic line, Clairant theorem, algorithm design
