基于NT的海战场三维地形的生成与实时显示

海战场环境仿真是海军作战模拟的重要内容，逼真的战场环境实时仿真是作战模拟的基础，它为保障、分析、作战评估等试验提供了仿真平台。针对海战场仿真中大规模三维地形的生成与实时显示问题，提出了一种基于VEGA和NT平台的解决方案，讨论了DEM数据的组织及分割、数据格式的转换以生成OpenFlight格式的地形数据，介绍如何把地形数据加入VEGA场景中重新拼接，设置视点参数，最后转换为Fret格式实现实时显示。

Building and Real-time Display of 3D Terrain in Battlefield Based on NT Platform

The Simulation of naval battlefield environment is very importment in fighting simulation system . The vivid and real - time simulation of naval battlefield environment is the base of fighting simulation system, which offers a very nice simulation platform for fighting evaluation. In order to solve the problem of building and real - time display of large scale terrain in battlefield environment, this paper proposes a solution based on Vega. It discusses the organization and division of DEM , convertion of DEM data format to DED and DED to OpenFlight, then introduces how to load the terrain data in Vega scene and rebuild them, configure the parameter of view - point, convert to fast file format and finally display real - time.
