Automatic Semantic-preserving Conversion Between OBJ and CityGML
(The Eurographics Association, 2015)
We investigate the automatic conversion between two substantially different formats used in 3D city models: the ubiquitous but semantically poor Wavefront OBJ and the semantically rich but less used OGC standard CityGML. ...
Conceptualizing, Managing and Developing: A Web Based 3D City Information Model for Urban Energy Demand Simulation
(The Eurographics Association, 2015)
In this paper we describe a concept to manage and develop a web based virtual 3D scene, based on CityGML LoD 2 models, DTM tiles, ortho-photos and energy simulation results of specific heating demand and photovoltaic ...
