Initial Exploration from Virtual Scene Simulation of Multibeam Submarine Topography in the South of the Okinawa Trough

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.
