三维旅游场景可视化研究

Visualization of Three-dimensional Scene

首先建立DEM模型、地物模型、建筑物模型等要素,然后将各要素叠加建立三维旅游场景,再对该场景模型进行缓冲分析、场景自动旋转、沿路线旅游、录制视频等操作,从而达到虚拟旅游的效果。系统运行结果表明该场景效果逼真,运行速度较快,基本可以满足游客需求。

Visualization of three-dimensional scenes was studied. Different models, such as digital elevation, terrain, and building were established firstly, and they were then combined to build up three dimensional scenes. The resultant scene models were subjected to a series of operations, such as buffer analysis, scene autorotation, touring along the route, and video recording, to obtain the effect of virtual tourism. The results indicated that the virtual scene could make tourists feel realistic with suitable speed and meet the demands of tourists basically.
