Title:
- A screen-space approach to rendering polylines on terrain

Abstract:
A fundamental task in virtual globe and GIS applications is to render polyline vector data representing elements such as political borders, road networks, and rivers. Rendering polylines such that they precisely drape over terrain is challenging. We present an approach that extrudes the original polyline, forming a wall, and intersects the wall with the terrain in screen-space to find the desired polyline.
