一种运用OpenGL快速构建三维模拟地形的方法

A Quick Method for Building Three-Dimensional Simulative Terrain Based on OpenGL

该文针对现代局部战争中出现的新情况给防空兵作战仿真带来的影响,研究了一种运用OpenGL三维图形库技术,通过分析几种常见地形的主要特征,从中提取用于作战仿真的重要参数,快速的构建三维模拟地形的新方法。它克服了通常作战仿真中采用遥感影像式数字高程模拟方法,数据结构复杂,图形生成速度慢等不足。同时它也能够帮助指战员在短时间内认知不同的战场环境,为他们运筹帷幄提供保障。通过对防空兵分队作战地形中山地模型的构建,验证了该方法的有效性和实用性。

This article is based on the new circumstances appeared in the modern local war that have influence on air defence operation simulation, studies a new method to quickly build three - dimensional simulative terrain by using OpenGL. Some important parameters used in operation simulation are picked up by analyzing primary characteristic of common terrain. The method surmounts some shortcomings of using Remote Sensing Image Digital Elevation Model, such as the complicated data structure, the slower image formative speed and so on. In addition, it also can help commander to cognize different battlefield environments in short time, and provides the guarantee for they devise strategies within a command tent. Using the method to build upland of air defence forces＇ operation terrain proves the effectiveness and practicality.
