Construction and Application of Virtual Roaming System Based on Virtools

This paper introduced a virtual roaming system which can be effectively used in studying ocean scenes based on 3ds max modeling tools and virtools development software. Establishing this system needs the following steps: building geometric model, making texture mapping, light treatment, importing model and designing interactive function. Taking jack-up offshore platform as an example, the system has three roaming modes including manual roaming with character, manual roaming without character and automatic roaming. Users can roam in this platform freely. The collision detection technology and the immersive technology were integrated into the system to improve the reality of it. The system also has a good visual effect and interactive function.
