为在土木建筑工程中应用NURBS造型方法实现真实感虚拟表现和仿真，在OpenGL图形处理平台上自主开发了专业造型工具，成功地实现了基于NURBS方法的翼角自由曲面的复杂造型功能。这是NURBS方法在建筑工程领域中应用的成功尝试。所用的NURBS造型方法和模型具有可复用性，可以推广应用于其他复杂自由曲面造型的实现，说明NURBS方法在该领域具有很好的应用发展前景。 In order to achieve realistic virtual performance and simulation using NURBS modeling method in civil engineering, a professional modeling tool was independently developed on the OpenGL graphics processing platform, and the complex modeling function of the wing-angle freeform surface based on the NURBS method was successfully implemented. This is a successful attempt to apply the NURBS method in the field of construction engineering. The NURBS modelling methods and models used are reusable, which can be applied to the realization of other complex freeform surfaces. It shows that the NURBS method has a good application development prospect in this field.
