    • Visibility of Building Exposed Surfaces for the Potential Application of Solar Panels: A Photometric Model 

      Florio, Pietro; Roecker, C.; Probst, M. C. Munari; Scartezzini, Jean-Louis (The Eurographics Association, 2016)
      Urban areas are facing a growing deployment of solar technologies on the built exposed surfaces such as roofs and façades. This transformation often occurs without consideration of the needed architectural quality, which ...
    • Optimizing Window Shape for Daylighting: An Urban Context Approach 

      Fernández, Eduardo; Aguerre, José Pedro; Beckers, Benoit; Besuievsky, Gonzalo (The Eurographics Association, 2016)
      Configuring the optimal shape and position of a building opening, such as windows or skylights, is a crucial task for daylight availability. Computing daylighting requires the use of climate-based data, which involves large ...
    • 3D Model for Solar Energy Potential on Buildings from Urban LiDAR Data 

      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. ...
    • Interactive Low-Cost Wind Simulation For Cities 

      Rando, Eduard; Muñoz, Imanol; Patow, Gustavo (The Eurographics Association, 2016)
      Wind is an ubiquitous phenomenon on earth, and its behavior is well studied in many fields. However, its study inside a urban landscape remains an elusive target for large areas given the high complexity of the interactions ...
    • Point Clouds as an Efficient Multiscale Layered Spatial Representation 

      Poux, Florent; Neuville, Romain; Hallot, Pierre; Billen, Roland (The Eurographics Association, 2016)
      3D point clouds describe urban shape at different scales, precisions and resolutions depending on the underlying sensors and acquisition methodology. These factors influence the quality of the data, as well as its ...
    • Procedural Generation of Traffic Signs 

      Taal, Fieke C.; Bidarra, Rafael (The Eurographics Association, 2016)
      Procedurally-generated virtual urban worlds typically miss plausible signaling objects on the road network, unless they were manually inserted. We present a solution to the problem of procedurally populating a given urban ...
    • 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 ...
    • Realistic Urban Road Network Modelling From GIS Data 

      Nguyen, Hoang Ha; Desbenoit, Brett; Daniel, Marc (The Eurographics Association, 2016)
      Starting from GIS data, which are sampled and often inaccurate, this paper presents a method to reconstruct urban road surfaces respecting important geometric constraints selected from civil engineering. We propose a ...
