Abstract

City models visualisation, buildings, structures and volumetric information, is an important task in Computer Graphics and Urban Planning. The different formats and data sources involved in the visualisation make the development of applications a big challenge. We present a homogeneous web visualisation framework using X3DOM and MEDX3DOM for the visualisation of these urban objects. We present an integration of different declarative data sources, enabling the utilization of advanced visualisation algorithms to render the models. It has been tested with a city model composed of buildings from the Madrid University Campus, some volumetric datasets coming from Air Quality Models and 2D layers wind datasets. Results show that the visualisation of all the urban models can be performed in real time on the Web. An HTML5 web interface is presented to the users, enabling real time modifications of visualisation parameters.
