The simulation system of the new marine simulator is established based on the software Videotrace and VRML language. Many kinds of high and new technologies such as 3D modeling, calibration modeling of the cloud server, the interactive design of the virtual scene have been used in the simulation platform of virtual marine simulator. The new simulation system has further development and excellent interaction function. At the same time, research of virtual marine simulator is carried out for the purpose of improving the development of navigation simulator and the training model in the compound seafarers.
