摘　　要：基于Direct3D平台的三维虚拟地形控件,是通过GDAL库接口读取GeoTIFF格式的DEM数字高程文件,自动生成地表立体模型并实时渲染,真实和直观地重现地形起伏态势,能流畅地支持各种用户交互浏览操作,还能实现地表贴图的任意更换。该控件是专门面向Direct3D平台的三维虚拟地形显示控件,作为电子沙盘的核心显示接口,可广泛应用于物探工区的踏勘、测绘、GIS、导航、调度等仿真用途。Direct3D platform based on 3D virtual terrain of control is read through GDAL library interface GeoTIFF for- mat DEM file, automatically generated 3D surface model and real-time rendering, real and intuitionistic to reproduce the topography of the situation, to smoothly support a variety of user interactive browsing operations, but also to a- chieve the surface textures of arbitrary replacement. The control is designed specifically for Direct3D platform of 3D terrain display controls, as the core of electronic sand table display interface, can he widely used in geophysical ex- ploration work area reconnaissance and mapping, GIS, navigation, scheduling and other simulation purposes.
