摘要： 为了在网络环境下使地上下无缝集成模型具有更加逼真的显示效果,分别采用主动式和被动式两种方法实现三维模型的立体显示.地上下集成模型以CD-TIN为纽带,将地上建筑物、地表与地下空间实体进行无缝集成.根据立体图像对的生成原理实现三维模型的立体显示,并使用ActiveX控件实现三维模型的网络化表达,从而构建了一个网络环境下的地上下无缝集成模型立体显示系统.观察者通过佩戴立体眼镜即可观察三维立体模型.实验结果表明,采用立体显示方法能增强模型的显示效果,使观察者产生较强的沉浸感,有利于对三维地学模型的观察和分析.

Abstract: In order to have a more realistic display of the seamless integrated model of city surface and subsurface under Internet environment, 3D models were stereoscopically displayed by both active and passive methods. With the CD-TIN as a link, city surface and subsurface integrated model seamlessly integrated the buildings, the ground and the spatial entities underground together. Stereo display of the 3D models was realized according to the principle of stereo vision. Using ActiveX control, 3D models were displayed on web pages. Watchers with stereo glasses can thus view 3D models. The results showed that the stereo viewing can enhance the display effect of the model and induce a strong sense of immersion. It is favorable to the observation and analysis of the spatial geological model.
