Description: “虚拟地景生成系统”是基于Windows2000系统和Visual C++ 6.0平台，利用基本OpenGL函数编程技术开发的三维可视化成果。它通过简单的DEM（数字高程模型）数据，建立格网模型、再根据光照强度、高程值及有关数据建立数学模型，生成晕渲，再将它投影到平面上，达到模拟现实地貌起伏的效果。 本系统采用XP风格界面，清新自然。它具有透射/正射投影切换、漫游、缩放功能。支持分层晕渲、比高设定、平移、旋转、翻滚、视野调节、雾化、纹理贴图(显示/隐藏)等诸多功能，单幅、1MB大小的DEM数据生成速度为秒级，浏览时无停顿。-"to the virtual scene generation system" is based on Windows 2000 and Visual C 6.0 platform, using the basic function of OpenGL programming technology developed by 3D visualization results. Through simple DEM (Digital Elevation Model) data, establish grid model, in accordance with light intensity, elevation data and the value of a mathematical model, generate Hillshading, then it projection plane to achieve realistic simulation of the effect of undulating topography. The system uses XP style interface as well. It has transmission / switching are overhead projectors, roaming, zoom function. Support for layered Hillshading, compete against the creation, translation, rotation, rolling and vision adjustment, atomization, textures (Show / Hide), and many other functions, Single, 1MB s

Description: 一篇文章，利用DWG格式地形图建立城DEM，
利用VBA 语言编程,提取离散高程点及其高程注记,并将高程点与高程注记匹配存储
对等高线进行有效的离散化,提取等高线的高程信息.而后将提取的高程数据在ArcGIS以三维可视化的人机交互的方式剔除粗差,最后生成DEM.-an article, the use of topographical maps DWG format established City DEM using VBA programming language. Elevation extract discrete points and elevation Note, and elevation and elevation point Note matching storage right contour effective discrete, Extracting the elevation contour information. and after extraction of elevation data to the ArcGIS 3D visualization of Human-Computer Interaction way removed gross error, the last generation DEM.

Description: 主要研究和探讨了基于DirectX的真实感地形实时渲染技术。文章在规则格网DEM基础之上,采用基
于LOD的DEM多分辨率动态构网技术和多层纹理贴图方法,生成比较真实的地面景观,同时添加了天空、烟雾等
效果,使显示效果更加真实。生成的三维地形的渲染速度达到了20～30帧,基本上满足了实时显示的要求。转载,只供参考!谢谢!-major research and exploration based on the realistic terrain DirectX real-time rendering technology. Based on the grid DEM basis, LOD based on the DEM Multi-resolution structural dynamic network technology and multi-texture mapping, Generating more about the real landscape, but added the sky, smoke and other effects, effects, more real. Generation of 3D terrain rendering speed reached 20 ~ 30, basically meeting the needs of real-time display requirements. Reproduced for reference! Thank you!
