城市交通环境视景三维仿真

为解决城市视景仿真还原度差、系统流畅度不佳等问题,提出一种基于Vega Prime与VC++联合仿真的视景仿真框架。使用Multigen Creator与3D MAX联合建模,在VC++环境下利用Vega Prime实现场景动态驱动。并着重研究了模型优化、节点动态驱动、模型封装等视景仿真关键技术。利用上述视景建模关键技术,完成城市交通环境视景仿真系统搭建。应用结果表明：关键技术的应用将视景加载时间缩短为初始加载时间的1/6,平均帧频提升约30%,并提供了丰富逼真的图形画面,良好的用户感受,呈现出高还原度的视景仿真效果。

3D Visual Scene Simulation of Urban Traffic Environment

In order to solve the problem of poor restoration and poor system fluency in urban visual simulation, a visual simulation framework based on co-simulation of Vega Prime and VC++ is proposed. Multigen Creator and 3D MAX are used to model the scene and Vega Prime is used to realize scene dynamic driving in VC++ environment. The key technologies of visual simulation such as model optimization, node dynamic driving and model encapsulation are studied. The construction of the urban traffic environment visual simulation system is completed with the key technologies of vision modeling. The results show that application of key technologies shortens the view loading time to 1/6 of the initial loading time and increases the average frame rate by about 30%. The visual simulation system provides rich and realistic graphic images, good user experience and high-reliability visual simulation effects.
