| 摘 要： | 本文叙述了多细节层次(LODs)相关应用,对基于LODs技术的不同数据库表达方式进行了详细阐述,分析了LODs中不同细节层次平滑切换缓冲技术的应用原理。首先对大庄矿虚拟中使用LODs技术,较好地解决了原模型浏览时视觉不连续和画面跳变的问题。接着用VRML编程实现网上发布模型的LODs,解决了在IE等浏览器中模型漫游时不连续的问题。

| Abstract: | This article firstly introduces the applications of LODs.Then particularly expatiates on the categoriesof LODs-based database expression and the theory of morphing between the levels of LODs that can make themodels switch smoothly.In the application aspect,the LODs technique was firstly employed to several models ofDazhuang Coal Mine,which preferably resolved the problems of visual discontinuity and image leap when ex-ploring the original models.Secondly,the VRML was employed to the LODs of network release models,whichpreferably resolved the problem of discontinuity of models when exploring in IE explorer. |
