【摘要】 叶轮广泛应用于动力机械等领域。采用NURBS曲面能对叶轮型面进行有效描述,而采用OpenGL技术能对NURBS曲面叶轮进行可视化造型。文章首先介绍了NURBS曲面的数学表达方法,概述了通过OpenGL构造三维图形的一般工作流程及方法。利用VC++6.0开发平台,基于OpenGL技术实现了NURBS叶轮曲面的构造和可视化。文中给出了叶轮可视化造型实例。更多还原

【Abstract】 Impellers is widely used in the field of power mechanism. The impeller surface model can be described by NURBS surface while the visualization of the NURBS surface can be realized by OpenGL technology. This paper introduces firstly the mathematic expression of NURBS surface, and summarizes the general workflow to construct 3D graph through OpenGL. The NURBS surface of impellers is constructed and visualized by OpenGL on the VC++ 6.0 platform. A visual modeling example for an impeller is given.更多还原
