    • NightLighting: a Nocturnal Urban Illumination Approach 

      Muñoz-Pandiella, Imanol; Andújar, Carlos; Patow, Gustavo (The Eurographics Association, 2013)
      Real time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ...

    • 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 ...

    • A General Strategy for Semantic Levels of Detail Visualization in Urban Environment 

      Zhang, Fan; Tourre, Vincent; Moreau, Guillaume (The Eurographics Association, 2013)
      Applications based on urban environments are applied frequently in daily life which increases the needs for a high quality visualization result. It combines the urban environment and the special application-related topic ...

    • Inverse-Procedural Methods for Urban Models 

      Musialski, Przemyslaw; Wimmer, Michael (The Eurographics Association, 2013)
      Procedural modeling is an elegant and fast way to generate huge complex and realistically looking urban sites. Due to its generative nature it can also be referred to as forward-procedural modeling. Its major drawback is ...

    • 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 ...

    • Understanding City Dynamics through Spatio-temporal Visualization 

      Dias, Luís; Silva, Nelson; Cardoso, Tiago; Fonseca, Manuel J. (The Eurographics Association, 2013)
      Every time we visit a new city there is a huge effort made in understanding its dynamic, i.e. what are the relevant locations within that city in each time period, for there are large amounts of data to sift through. ...

    • Toward Automated Façades Generation from Oblique Aerial Images 

      Vahl, Matthias; Lukas, Uwe von (The Eurographics Association, 2013)
      In this paper we introduce an approach for automatic recognition and description of building façades from oblique aerial images. This approach does not use street-side images, like Google StreetView, but aerial images to ...

    • Online Reconstruction of Textured Triangle Meshes from Aerial Images 

      Vierjahn, Tom; Roters, Jan; Moser, Manuel; Hinrichs, Klaus; Mostafawy, Sina (The Eurographics Association, 2013)
      In this paper we present and evaluate a new online reconstruction algorithm to create a textured triangle mesh from a set of aerial images via an unorganized point cloud. Both the point cloud and the mesh are iteratively ...

    • Indoor Scene Reconstruction using Primitive-driven Space Partitioning and Graph-cut 

      Oesau, Sven; Lafarge, Florent; Alliez, Pierre (The Eurographics Association, 2013)
      We present a method for automatic reconstruction of permanent structures of indoor scenes, such as walls, floors and ceilings, from raw point clouds acquired by laser scanners. Our approach employs graph-cut to solve an ...

    • Taking Advantage of Low Radiative Coupling in 3D Urban Models 

      Beckers, Benoit (The Eurographics Association, 2013)
      We examine different techniques able to enhance the efficiency of urban simulations. Condensation techniques like superelements - well known in the finite element community - are good candidates to improve the heat transfers ...

    • Dual-Domain Visual Exploration of Urban Solar Potential 

      Seipel, Stefan; Lingfors, David; Widén, Joakim (The Eurographics Association, 2013)
      Traditional methods for estimating the solar energy potential in buildings determine energy yields on an annual base and make use of highly aggregated geo-spatial data. This work proposes a method for detailed assessment ...

    • Interactive Techniques for Populating Large Virtual Cities 

      Jordao, Kevin; Pettré, Julien; Cani, Marie-Paule (The Eurographics Association, 2013)
      For many applications, exploring empty virtual cities is not sufficient: streets and squares need to be populated by crowds of virtual humans. This position paper addresses the problem of generating such crowds when the ...
