    • 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 ...

    • A Data Model for Simulation Models Relying on Spatio-temporal Urban Data 

      Langlois, Jean-Gil; Tourre, Vincent; Servières, Myriam; Gervais, B.; Gesquière, Gilles (The Eurographics Association, 2016)
      To understand the complexity of modern cities and anticipate their expansion, experts from various fields conceive simulation models that can be very different. Those simulation models work with a variety of data with their ...

    • Dynamizers - Modeling and Implementing Dynamic Properties for Semantic 3D City Models 

      Chaturvedi, Kanishk; Kolbe, Thomas H. (The Eurographics Association, 2015)
      Today, more and more cities worldwide are realizing the importance of semantic 3D city models. Various application areas of 3D city models such as simulations require the usage of highly dynamic and time-varying attributes, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Visibility Analysis in a Point Cloud Based on the Medial Axis Transform 

      Peters, Ravi; Ledoux, Hugo; Biljecki, Filip (The Eurographics Association, 2015)
      Visibility analysis is an important application of 3D GIS data. Current approaches require 3D city models that are often derived from detailed aerial point clouds. We present an approach to visibility analysis that does ...
