Problems solved by technology

[0003] In the field of ship engineering, the hydrodynamic performance of a ship usually requires a ship model test. In the prior art, it is necessary to establish a ship model that is geometrically similar to the designed ship for various tests such as resistance performance and seakeeping performance. The cost is high and it cannot be obtained. valid test results
[0004] For this reason, the industry has begun to use virtual test platforms to simulate ships to simulate ship performance through programs. However, these simulations cannot be experienced by real people. How to provide a system that facilitates real people to experience and simulate real ship navigation has become a technical problem that needs to be solved at present.
