Study a variety of ship motion states, in order to provide a platform for the effective verification of the controller function. The scene simulation systems were developed by using ship motion visualization, and commonly used models and driving technologies used in developing scene simulation systems were studied. An overall design and process of the scene simulation system of ship motion were proposed, A realistic 3D model of ship was built based on the modeling software Creator. The movable models of main/flap rudder, main/flap fin and propeller were estab- lished using the DOF node technology. The key technologies of scene simulation system were resolved, such as viewpoint switching, multi-channel showing, simulation data loading. The scene simulation system was implemented through the combination of the Vega API programming technology and the language environment of VC ＋ ＋. Finally, three-dimensional simulation results demonstrate the good interactive and fidelity of the system. A reliable means has been provided for studying characteristics of ship motions.
