      Bill, Andreas; Mohajeri, Nahid; Scartezzini, Jean-Louis (The Eurographics Association, 2016)
      One of the most promising sustainable energies that can be considered in urban environments is solar energy. A 3D model for solar energy potential on building envelopes based on urban LiDAR data was developed in this study. ...

    • 5D Multi-Purpose Land Information System 

      Ioannidis, Charalabos; Verykokou, Styliani; Soile, Sofia; Potsiou, Chryssy (The Eurographics Association, 2015)
      The complexity of modern urban environments has led to the introduction of 3D Land Information Systems (LISs), which tend to replace traditional 2D LIS architectures for the purposes of urban planning and regeneration, ...

    • 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 ...

    • Automated Production of Interactive 3D Temporal Geovisualizations so as to Enhance Flood Risk Awareness 

      Jacquinod, Florence; Pedrinis, Frédéric; Edert, Jérémy; Gesquière, Gilles (The Eurographics Association, 2016)
      The FLOOD AR project originates from an explicitly expressed need for digital 3D temporal georeferenced models that can be largely diffused among riverside residents through computers and mobile devices, in order to support ...

    • An Automatic Comparison Approach to Detect Errors on 3D City Models 

      Gorszczyk, Benjamin; Damiand, Guillaume; Servigne, Sylvie; Diakité, Abdoulaye; Gesquière, Gilles (The Eurographics Association, 2016)
      3D building models are needed in several professional domains. To provide better results, these models must be errors-free and that is why it is required to have a way to detect and to correct errors. These errors can be ...

    • Automatic Semantic-preserving Conversion Between OBJ and CityGML 

      Biljecki, Filip; Arroyo Ohori, Ken (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. ...

    • Challenges and Ideas in Procedural Modeling of Interiors 

      Ilcik, Martin; Wimmer, Michael (The Eurographics Association, 2013)
      While the creation of convincing cityscapes from the outside is already possible, there is a lack of robust and efficient techniques for modeling the interior of buildings. In particular, we focus on challenges for the ...

    • Challenges in Procedural Modeling of Buildings 

      Patow, Gustavo; Besuievsky, Gonzalo (The Eurographics Association, 2013)
      The use of procedural modeling for building generation has risen dramatically over the last years, being an elegant and fast way to generate huge, complex and realistically looking urban sites. However, due to its generative ...

    • City Reconstruction and Visualization from Public Data Sources 

      Menzel, J. Robert; Middelberg, Sven; Trettner, Philip; Jonas, Bastian; Kobbelt, Leif (The Eurographics Association, 2016)
      We present a city reconstruction and visualization framework that integrates geometric models reconstructed with a range of different techniques. The framework generates the vast majority of buildings procedurally, which ...

    • Combining Geometry, Topology and Semantics for Generic Building Description and Simulations 

      Horna, Sébastien; Damiand, Guillaume; Diakité, Abdoulaye; Meneveaux, Daniel (The Eurographics Association, 2015)
      2D and 3D virtual architectural models are the common ground of many studies, including environmental protection, energy saving, or human well-being. Building or urban environment simulations concern for instance heat ...

    • Commercial Evolution Simulation 

      Soriano, Carlos; Patow, Gustavo (The Eurographics Association, 2015)
      Simulating the evolution of urban landscapes is a challenging objective with a large impact not only for Computer Graphics (for its applications in the filming and gaming industries), but also for urban planning, economical ...

    • Conceptualizing, Managing and Developing: A Web Based 3D City Information Model for Urban Energy Demand Simulation 

      Padsala, Rushikesh; Coors, Volker (The Eurographics Association, 2015)
