Abstract:
The process of rendering and interacting with large scenes in web systems is still an open problem in 3D urban environments. In this paper we propose a prototype to visualize a city model in a client-server architecture using open-source technologies like WebGL and X3DOM. Moreover, free navigation around the scene is allowed and users are able to obtain additional information when interacting with buildings and street furniture. To achieve this objective, aMySQL geodatabase has been designed to store both geometric and non-geometric urban information. Therefore, the extra data about the urban elements is obtained through queries in the database. The communication process between MySQL and the X3D model is performed by Ajax.
