大比例尺矢量地图的交互式渲染是高质量地理可视化软件系统的一个关键挑战。在本文中，我们提出了一种在详细的高度场地形上可视化大规模矢量图的新方法。我们的方法使用延迟线着色方法直接在地形可视化的屏幕空间着色阶段渲染大规模矢量图。事实上，不涉及传统的几何多边形渲染，使得我们的算法优于地理信息系统的传统矢量图渲染算法。我们灵活的集群延迟线渲染方法允许用户交互式地定制和应用高级矢量样式方法，以及集成到矢量地图细节级别系统中。
Interactive rendering of large scale vector maps is a key challenge for high-quality geographic visualization software systems. In this paper we present a novel approach for the visualization of large scale vector maps over detailed height-field terrains. Our method uses a deferred line shading approach to render large scale vector maps directly in a screen-space shading stage over a terrain visualization. The fact that there is no traditional geometric polygonal rendering involved allows our algorithm to outperform conventional vector map rendering algorithms for geographic information systems. Our flexible clustered deferred line rendering approach allows a user to interactively customize and apply advanced vector styling methods, as well as the integration into a vector map level-of-detail system.
