摘　　要：针对冲绳海槽南部海底地形,首先根据等效声速剖面原理处理原始多波束地形数据,使得多波束条带之间拼接良好;然后以Creator和Creator Terrain Studio为主要工具,生成地形和纹理数据集以构建海底地形场景库;最后在Vega Prime运行环境中进行交互。利用多通道实时渲染和立体投影技术,使用户最终得到对虚拟图像的真实感、立体感和沉浸感。Aiming at the south of the Okinawa Trough, raw multibeam data is processed by equivalent sound velocity profile principle firstly. Then topography terrain dataset and texture dataset are generated to construct submarine topography scene database by Creator and Creator Terrain Studio. Finally the authors establish the submarine topography scene database in the Vega Prime running environment. Using multi-channel real-time rendering and stereo projection technique, it can be felt real, stereoscopic and immersed.
