| Abstract: | 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 ... |
