摘要
定义了移动电子地图中伪3D可视化概念,提出伪3D可视化模型,并设计了快速的三维投影变换算法。进行了移动电子地图的伪3D可视化实验设计,并给出了可视化性能测试结果。
Firstly,this paper defines the concept of pseudo 3D visualizations in mobile maps. Secondly,the paper proposes a pseudo visualization model and designs a rapid 3D projection transformation algorithm. Thirdly, in order to show a realistic 3D scene with 2D data, a kind of method of pseudo 3D pre processing is proposed and a necessary enhanced 3D technology is adopted. Finally, pseudo 3D visualization from 2D vector data was implemented for mobile maps. Live pseudo 3D maps are produced and shown on mobile devices at real time. The experimental results are given in the paper.
