摘要
针对三维虚拟城市系统在高逼真度、强交互性和高精度等方面的不足,提出基于Unity3D平台的三维虚拟城市的实现方法。首先通过三维地形的数据采集和坐标数据统一,实现三维模型的建立和导入,纹理数据的建立和导入。在此基础上结合三维引擎Unity3D平台,实现三维模型数据与二维空间数据整合、三维虚拟漫游、三维物理效应仿真等。该系统采用了真实的数据进行实验,证明了采用该三维虚拟技术很好地满足三维虚拟城市系统的各项指标,并且实现效率高。
In order to improve the 3D virtual city system deficiency of high fidelity, strong interaction and high precision etc, proposed the realization method of 3D virtual city based on the Unity3D platform. First, the three-dimensional terrain data should be collected and established, besides, built and imported the three-dimensional model. On this basis, combined with the Unity3D platform of 3D engine, realize integration of the 3D model data and 2D spatial data, the 3D virtual wandering and the effect of three-dimensional physical simulation etc. Finally ,the system used real data to test,proved that the 3D virtual technology achieves each indicator of 3D virtual city system well,and has completion of high efficiency.
