基于CGF的航空装备实验室建模技术研究

分析了国内外CGF的研究现状,提出了基于CGF的航空装备实验室建模技术,重点阐述了战场环境的加载机理、网格信息层和文化特征信息层的创建过程;其中,网格信息层采用bmp格式的光栅图像文件来创建,将光栅文件具体细化成多个部分,再通过编辑mtl文件,为所划分的部分设定属性,再将这些部分连接起来,拼合成网格信息层;在文化特征信息层中对点状文化特征、线状文化特征和面状文化特征进行了研究.点状文化特征在战场环境中通过单个具有矢量信息的点来表示.线状文化特征在战场环境中通过一组有序的矢量点来表示.面状文化特征在战场环境中通过一组有序闭合的矢量点来表示,两个相邻的点之间用线段连接起来就成了折线,然后把首尾连接起来就成了多边形,多边形内部的区域具有同一文化特征.

The Study of Aeronautical Equipment Lab' s Environment Modeling Technique Based on the CGF

The reasearch work of the CGF was analysed,then Aeronautical Equipment Research Lab's environment modeling technique was put forward;battlefield enviroment's loading mechanism,the mesh information layer and the cultural characteristic were mainly stated.The mesh information layer was created form the raster image of the bmp,which is constituted by the fragment and properties were set by editing the mtl documents;the point cultural characteristic,the line and area cultural characteristic were researched in t...
