Abstract
By combining two previously unrelated techniques - semantic markup in a scene-graph and generative modeling - a new framework retains semantic information until late in the rendering pipeline. This is a crucial prerequisite for achieving enhanced visualization effects and interactive behavior that doesn't compromise interactive frame rates. The proposed system creates interactive 3D visualizations from 2D geospatial databases in the domain of utility companies' underground infrastructure, creating urban models based on the companies' real-world data. The system encodes the 3D models in a scene-graph that mixes visual models with semantic markup that interactively filters and styles the models. The actual graphics primitives are generated on the fly by scripts that are attached to the scene-graph nodes.
