利用Direct3D的地形三维快速重建方法

The Quick 3D Rebuliding Technology of Viewport Terrain Data Based on Direct3D

在视口数据检索之后,视口重建效率成为了影响地形数据三维重建和显示速度的主要因素,视口重建与可利用的开发平台资源密切相关。在剖析Direct3D硬件访问方式的基础上,提出了一套完整的DEM快速重建方法。实验结果表明在相同的条件下,基于Direct3D的视口重建具有明显的速度优势。

The efficiency of viewport 3D rebuliding become the most important factor to affect the terrian 3D rebuliding and display rate.Viewport 3D rebuliding is affinitive to the resource of available exploitation environment.This paper puts forward a whole set of technology for fast 3D rebulid DEM data in viewport.The result of experimentation presents that the technology of viewport rebuliding based on Direct3D has an advantage in speed either in same software or in hardware conditions.
