基于Terra Vista的真实大地景模拟仿真

Simulation of Real-Large Land Scene Based on Terra Vista

真实大地景模拟在许多虚拟仿真系统中起重要作用。针对大地景的逼真度和刷新率相互制约的问题,介绍了一种基于Terra Vista的虚拟仿真大地景设计和实现方法。阐述了虚拟仿真中地形数据、纹理数据、模型数据的选择和制作流程,详细说明了陆海视景仿真的实现方法。实例验证了基于Terra Vista的真实大地景仿真设计方法的有效性。

Real-Large land Scene visualization plays an important role in a lot of virtual simulation systems. To solve mutual restrictive problem between the fidelity and fluentness of large land scene, this paper introduces a real-large land scene design scheme based on Terra Vista for virtual simulation. In the paper, the selection and production flow of terrain data, texture data and model data are expatiated. The implement of methods are explicated for round earth marine visualization. Examples verify that the design method of real-large land scene simulation based on Terra Vista is effective.
