摘　　要：在大虚拟场景中,因为对环境的陌生,人们往往会迷失方向,而自主漫游模式与鹰眼导航相结合能解决在场景中无法定位的问题.使用网页脚本语言(Java Script)架起三维虚拟场景与二维平面的桥梁,这样使两者同步运行在超文本置标语言(HTML)页面中,让漫游者了解当前所在大虚拟场景中的位置,使任何人都可以在该场景中畅游无阻.For being unfamiliar with the environment,it＇s likely for people to get lost in a large virtual environment（VE）.Autonomous roaming combined with eagle eye navigation can resolve this problem of positioning in a large scene.By using web scripting language Java Script,the three-dimensional virtual scene and the two-dimensional plane were bridged and running synchronously in HTML page.It allows visitors to aware of their positions in the large virtual scene,thus anyone can roam unimpeded in the scene.
