Implement of distributed underwater virtual experimental environment platform for BOTMA

In terms of the implement problems of underwater BOTMA experimental platform,firstly,the experimental platform structure based on HLA is constructed.Secondly,the 3D environment is created by building the models of scene and entities.Thirdly,the implement of visual scene key techniques,such as entity display,multi-channel browse,virtual SE generation and intersection,are expounded.Finally,by introduction of system function and analysis of real-time capability,the conclusion is drawn that the platform can meet the need of various BOTMA simulations under 3D virtual condition.
