摘要
开发了一个基于谷歌地球的三维景观可视化系统,通过该系统不但可以在谷歌地球上进行景观规划并且可以模拟现有景观以方便用户进行虚拟漫游。本系统根据用户指令自动生成KML(Keyhole Markup Language)文件,而KML文件可以通过谷歌地球来显示。为了减少数据量,景观中的树木采用billboard技术来展示。根据系统测得的数据,树木被自动置于地面之上。通过本系统,基于测量的数据,模拟了一个真实的花园,并且组织用户进行了仿真漫游体验。运行结果和用户体验表明,本系统有良好的应用前景。
A 3D virtual wandering system which can simulate the landscape based on Google Earth was developed.With the system,users can not only realize the designed landscape,but also can wander in the virtual landscape.The system can generate KML(Keyhole Markup Language) file which can be visualized on Google Earth.By using billboard technique,it can express the trees with small data.With the system,it realized models of a real garden and organized some users to test the walk-through simulation.The results and the feedback of the users show that the system has the good performance and the potential of our system.
