基于Web的交互式三维发布系统

针对Web上三维场景漫游的需要，设计了一种基于Browser/Server结构的跨平台交互式三维发布系统。解决了漫游导航、感兴趣区域浏览、视点平滑移动、地形跟踪以及递进传输等三维浏览的关键技术，并实现了交互式的三维图形浏览器。该浏览器嵌入Web浏览器之中，采用递进传输模式；除提供场景漫游等基本操作外，还可使用二维地图导航和选取感兴趣区域浏览，自由控制光照，以及选择点、线、面等不同的外观表现手段对三维模型进行展示。

Interactive Web3D Publishing System

To provide better walkthroughs of 3D scene over the Internet, an interactive 3D publishing system based on Browser/Server architecture is designed. The system concerns key techniques of 3D walkthroughs, including navigation, ROI inspection, smooth viewpoint transition, terrain following and progressive transmission etc., and presents an interactive 3D browser embed in Web browser, in which users can walk in the scene with the help of 2D navigation map, rotate and scale the models, inspect ROI, control the light, and select the polygon rasterization mode such as point, line and fill to check 3D models.
