摘　　要：NURBS(Non-UniformRationalB-Splines)方法因其表示法的、形状控制灵活性,在曲面造型和曲面重构中具有重要作用。目前,还没有在C#中开发OpenGL(OpenGraphicsLibrary)的标准和规范的方法。研究了在C#中利用平台调结合OpenGL进行NURBS曲面快速建模的方法,获得了满意的结果,并给出了实例。NURBS is used in surface modeling and surface reconstruction widely due to its uniformity of representation and flexibility of shape control. There are not standards and uniform methods to develop OpenGL in C# yet. An approach of surface modeling in C# was proposed. NURBS surfaces were constructed rapidly using P/Invoke along with OpenGL. An example was also given. The result indicates that this approach has high efficiency in rapid modeling of NURBS surfaces and is convenient in modifying the local shape of surfaces.
