    • Topological Reconstruction of Complex 3D Buildings and Automatic Extraction of Levels of Detail 

      Diakité, Abdoulaye A.; Damiand, Guillaume; Maercke, Dirk Van (The Eurographics Association, 2014)
      This paper describes a new method allowing to retrieve the indoor and outdoor topology of a detailed 3D building model from its geometry and to extract different levels of detail (LoD) from the resulting topological ...
    • Visualizing Street Orientation and Solar Radiation in Relation to Complex Topography 

      Mohajeri, Nahid; Gudmundsson, Agust; Kämpf, Jérôme H.; Scartezzini, Jean Louis (The Eurographics Association, 2014)
      Street networks can be visualized in various ways depending on the purpose. Here we introduce (in the present context) a new technique for visualizing the orientation of street networks in relation to complex topography. ...
    • Hierarchical Radiosity for Procedural Urban Environments 

      Roure, Ferran; Besuievsky, Gonzalo; Patow, Gustavo (The Eurographics Association, 2014)
      In this paper we present a novel solution for the computation of diffuse global illumination in urban environments that takes advantage of the underlying structure of the procedural building models used for generating the ...
    • Ground Temperature Modelling: The Case Study of Rue des Maraîchers in Geneva 

      Upadhyay, Govinda; Kämpf, Jérôme; Scartezzini, Jean Louis (The Eurographics Association, 2014)
      This paper presents a methodology to approximate the urban heat island effect by using a PostgreSQL database and CitySim software, a simulation tool to evaluate urban energy flows. A ground temperature model has been ...
    • Applying Level-of-detail and Perceptive Effects to 3D Urban Semantics Visualization 

      Zhang, Fan; Tourre, Vincent; Moreau, Guillaume (The Eurographics Association, 2014)
      Urban environment consists of various types of data, both geometric ones and non-geometric ones, among which urban semantics are important sources for non-geometric data. The modelling and visualization of urban semantics ...
    • A Configurable LoD for Procedural Urban Models intended for Daylight Simulation 

      Besuievsky, Gonzalo; Barroso, Santiago; Beckers, Benoit; Patow, Gustavo (The Eurographics Association, 2014)
      In many applications, such as in massive urban models visualization or in the study of the impact of urban simulation at different scales, models with different levels of detail are required. In this paper we propose a ...
    • Incremental Plane-based Reconstruction and Exploration of Buildings in old Postcards 

      Younes, Lara; Romaniuk, Barbara; Bittar, Eric (The Eurographics Association, 2014)
      We present an approach for 3D reconstruction of a city model over the time from a collection of old postcards of the city of Reims. The planar structure of the buildings façades constraints the dense reconstruction of the ...
    • Managing Temporal Change of Cities with CityGML 

      Morel, Maxime; Gesquière, Gilles (The Eurographics Association, 2014)
      An increasing number of cities are developing digital models. It becomes thus necessary to take into account changes over time. Interoperability and thus the use of standards is also recommended. In this paper, we propose ...
