3D Visualization of Urban Data Based on CityGML with WebGL
Résumé
Due to the advances in computer graphics and improved network speed it is now possible to navigate in
3D virtual world in real time. Until now, technologies employed require to install standalone application or
plugins on navigators. The arrival of HTML 5 brings news solutions to visualize 3D data in a browser with
WebGL. Several globe projects have proven that such technologies can be employed. Unfortunately, demonstrations
are often based on proprietary formats to exchange or to store data. In this work, we propose to
use CityGML: a standard provided by the Open Geospatial Consortium. CityGML files are imported in our
Environment Editor. With several tools that we present in this paper, data are processed and stored. A client
server application is also presented to permit the visualization of geometry and semantic in a navigator
