中文摘要：

OpenGL图形库具有良好的3D图形生成功能，而科学计算可视化对于有限元分析软件是必不可少的部分。介绍了利用OpenGL图形库开发有限元模拟结果可视化系统的诸如消隐、局部图形放大、应力图的颜色平滑等关键技术，用此法开发了空心曲轴设计系统中的可视化后处理系统，提高了系统的可用性和计算结果的可读性。

英文摘要：

OpenGL graphic database has an ideal function of generating 3D graphics, and scientific computation visualization is absolutely necessary for finite element analysis software. This paper presents the key technologies, such as blanking, magnification of part graphic, smoothness of stress graphic, etc. of infinite element simulation result visualization system developed with OpenGL graphic database, and these methods are used to develop visualization post processing system in hollow crankshaft CAD system, improving the system usability and readability of computation result.
