According to the demand for parametric simulation of ship motion the method establishing data interface using VB6.0 through EonX control in the environment of EON was proposed. This method can implement the communication between internal object in VR system and external data, so the goal of accurate control and parametric simulation of ship motion can be achieved. The concrete methods can be listed as follows. First, the communication between the external data and the ship model in virtual reality system was implemented through the EonX control and Textbox control in VB. Second, the communication between the access database and the...
