Development And Application Of Virtual Reality System For Yacht Experience Design

The research for the realization of the yacht design experience,combined with the current development and application of virtual reality technology,put forward and create the yacht virtual reality system,to meet the user experience and preliminary design of virtual yacht expression and immersion program experience requirements.According to the classification and characteristics of virtual reality system,combined with the functional requirements of yacht virtual reality system,this system is divided into yacht roaming experience system and yacht driving manipulation experience system.Through the research of 3DS MAX modeling method,the craft of yacht and scene model was created and the texture of the model was processed with the material editing function of 3DS MAX software.The sky and marine environment model was built through the Unity virtual development software platform,and the visual simulation of yacht wharf and the simulation of yacht design effect were completed.Based on the analysis of ship motion freedom,coordinate system and motion equation,the five degree of freedom motion equation of yacht,yacht rolling and sway,yacht rotation and deceleration are summed up according to the established marine environment.Aiming at yacht virtual control platform,we completed yacht manipulation,virtual instrument and motion simulation,and driving interaction design.Through the roaming experience system,users can browse freely the effect of yacht's interior design and appearance design,and conduct the human-machine interaction guidance design for the roaming process.The system is developed by using the C# programming language in the Unity environment,and the functions of each system are encapsulated into EXCEL text functions,and the function expression is realized through the drive function of the universal engine.On the basis of visual simulation,the yacht roaming experience system and driving experience system are developed based on the world wide web engine,and the test and release of the desktop and immersion system of the yacht virtual reality system are completed in the development platform.
