摘要
为了生成光滑表面的虚拟模型,提出了一种基于IGES标准的NURBS虚拟仿真模型生成方法。文中详细讨论了该方法的实现过程,通过分析IGES标准,从中总结出NURBS实体模型的层次结构;设计了符合该标准的数据结构,给出了正确绘制NURBS虚拟模型的方法,最后使用实例验证提出的方法是切实可行的。
The virtual model is basic to construct the virtual reality environment. To create the virtual model of the slippery surface, the approach to the creation of NURBS virtual model is put forward based on IGES. The process of this approach is given in detail, in which the framework is summarized about the curve and surface model through analyzing IGES. The data structure accorded with IGES is designed. And the method to show rightly NURBS virtual model is presented as well. Finally, example verification validates that this approach is feasible.
