摘　　要：为满足国际海事组织(International Maritime Organization, IMO)海员培训、发证和值班标准国际公约(International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, STCW)2010年修正案提出的仿真训练需求,基于虚拟现实技术的三维虚拟船舶训练系统逐渐成为航海模拟器训练的有效扩展和补充。针对三维虚拟船舶开发过程中模型数量巨大和交互模型复用性差的问题,通过采用细节层次(Levels of Detail, LOD)模型构建三维虚拟船舶的几何模型,优化系统的真实感和实时性,实现虚拟船舶的三维场景漫游、碰撞检测和快速导航与瞬移,基于三维空间几何变换建立典型物体的交互模型。结果表明:开发的三维虚拟船舶训练系统真实感强,交互友好,已应用到航海仿真训练中,效果良好。Higher standard for seafarer training is requested by 2010 amendment of STCW(International Convention on Standards of Training, Certification and Watchkeeping for Seafarers) issued by IMO(International Maritime Organization), and 3 D virtual reality technology is being introduced into the marine simulator training. The LOD(Levels of Detail Modelling) is used in construction of the geometric model of 3 D virtual ship for better realistic presentation, real time response and reusability. 3 D scene roaming, collision detection, quick navigation and moving are achieved. The function for building 3 D interactive models through geometry transformation is available. The Design has been used in marine simulator training.
