摘要
利用曲面重建的方法和理论,采用两种数值方法:一是双三次Bernstein-B啨zier曲面片光滑拼接的算法,二是利用了三次样条插值的数值方法,对体育馆顶部进行了曲面模拟。首先通过VC++的OpenGL工具箱实现了双三次Bernstein-B啨zier曲面片光滑拼接的图形,并运用三次样条插值的数值方法求出曲面方程;然后再利用Matlab相应的命令做出模拟图。数据的误差分析表明了这一方法的可行性和实用性。
The curved shape simulation of the gymnasium＇s roof means of the methods and theory of the surface reconstruction. Two numerical methods are used as follows： smooth concatenation of triangular Bernstein - Bezier surface and cubic splines interpolation. By means of VC ＋ ＋ OpenGL, triangular Bernstein - Bezier surface graph is obtained. The equation of the surface is obtained by cubic splines interpolation. The simulation graph is obtained by means of Matlab. The feasibility and practicability of this method are verified by data error analysis.
