Real-time Screen-space Geometry Draping for Digital Terrain Models

Trapp, Matthias; Döllner, Jürgen in 23rd International Conference Information Visualisation (IV 2019) 2019 .

A fundamental task in 3D geovisualization and GIS applications is the visualization of vector data that can represent features such as transportation networks or land use coverage. Mapping or draping vector data represented by geometric primitives (e.g., polylines or polygons) to 3D digital elevation or terrain models is a challenging task. We present an interactive GPU-based approach that performs geometry-based draping of vector data on per-frame basis using an image-based representation of a 3D digital elevation or terrain model only.
