摘要
构建LNG船舶数字化三维模型,开发船舶6自由度运动数学模型,模拟各种海况条件下的船舶运动规律;运用海浪建模技术、柔性物体模拟技术实现高逼真度的航行场景模拟;利用LOD技术、遮挡剔除等场景优化方法提高动态场景的绘制效率。仿真结果表明,系统模拟较准确,场景沉浸感较好。
A digital 3D model of LNG ship was built,and a 6-DOF mathematical model of ship movement was developed to simulate ship movement laws under various sea conditions.The wave modeling technology and flexible object simulation technology were used to achieve high fidelity navigation scene simulation.The LOD technology,occlusion elimination and other scene optimization methods were adopted to improve the efficiency of dynamic scene rendering.The simulation results showed that the system has high operation efficiency,high simulation degree of ocean scene and good immersion.
