飞行仿真系统中基于CTS的地景设计

DESIGNING CTS-BASED LAND SCENE IN VIRTUAL FLIGHT SIMULATION SYSTEM

针对大地景的逼真度与流畅度相互制约的问题,介绍了一种基于CTS的飞行虚拟仿真大地景设计方案。详细说明了飞行虚拟仿真中地形数据、纹理数据、模型数据的选择和制作,根据仿真实例讨论了CTS中虚拟纹理的分层技术、地形的切片技术和LOD节点技术。实例验证了基于CTS的大地景仿真设计方法的有效性。

To solve mutual restrictive problem between the fidelity and fluentness of large land scene,this paper introduces a large land scene design scheme based on CTS for virtual flight simulation. In the paper the selection and production of terrain data,texture data and model data in virtual flight simulation are expatiated. According to simulation instances,the virtual texture layered technology,terrain slicing technology and LOD node technology in CTS are discussed as well. Examples verify that the CTS-based design method of large land scene simulation is effective.
