Considering current development of scene simulation technologies and practical request of ship voyage training emulator, this paper gives an architecture design of distributed and interactive ship voyage training emulator system based on scene simulation technologies,and studies the diftlculty and process of math modeling and three - dimensional modeling. It also researches the key technologies such as application of three - dimensional mouse and data glove, modeling of seabed terrain. This paper dilates the man -machine conversational interface and control of viewpoints, collision detection, visual hand. An implementation based on VR is presented at last, and the usage of ship voyage training emulator indicates its practicability, and the future research area is pointed out.
