河道三维可视化技术研究

Study on 3D interactive browsing and roaming system of river channel

为建立包括河道和周围景观在内的整体三维立体模型以及实现河道及其周围景观的三维动态实时浏览和漫游,采用和发展了LOD技术以及其它一系列图形加速的算法,实现了河道及其周围景观的交互式三维浏览和漫游。

For establishing 3D stereo model including river channel and surrounding landscapes and realizing 3D dynamic real-time browsing and wanderings, the LOD technology and series of other fast algorithm for figures are adopted and developed.Finally, the interactive browsing and roaming about river course and its surrounding landscapes are achieved.
