large-scale terrain是什么意思

用法例句

To create large-scale terrain in vision simulation based on MultiGen, two method can be adopted, one is to use LADBM module to load terrain dynamically in MultiGen Vega, the other is to incorporate many single DEM or DED models into a Large DED model, then convert it into terrain model in OpenFlight format.

基于MultiGen进行视景仿真时,为生成大规模地形,可以采用MultiGenVega中的大地形数据库管理模块LADBM在仿真时将多块连续的小地形动态装载,也可以将多块数字高程模型(DEM)或数字高程数据(DED)合并成一个大的DED地形,再利用MultiGenCreator将其转换成OpenFlight模型。

At present,there is no effective method to determine strong earthquake risk areas by use of geodetic deformation data.

利用大地形变资料进行地震危险区圈定尚无有效办法。

It is introduced the methods and steps for generating the large scale terrain models under the context of virtual battlefield environments.

以虚拟战场环境为背景,针对大地形可视化中的特殊要求,介绍了三维大地形模型的生成方法和步骤,阐述了地理数据格式的转化方法和人文特征的读取方法与显示途径。
