| Abstract: | This paper introduces a method of stencil volume of rendering linear vector data in OsgEarth, based on OSG and terrain which construted by DEM, Martin Schneider＇s method of vector data rendering idea; it has advantages such as real-time, efficiency and accuracy. Then author generalizes the structure below the visual of scene. Lastly, it was demonstrated being practicable, but still has some is its orginal hierarchical defects. |
