      Schnabel, Ruwen; Degener, Patrick; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We consider the problem of reconstruction from incomplete point-clouds. To find a closed mesh the reconstruction is guided by a set of primitive shapes which has been detected on the input point-cloud (e.g. planes, cylinders ...
    • Feature Preserving Point Set Surfaces based on Non-Linear Kernel Regression 

      Oeztireli, A. C.; Guennebaud, G.; Gross, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Moving least squares (MLS) is a very attractive tool to design effective meshless surface representations. However, as long as approximations are performed in a least square sense, the resulting definitions remain sensitive ...

      We present a simulation system that can simulate a three-dimensional urban model over time. The main novelty of our approach is that we do not rely on land-use simulation on a regular grid, but instead build a complete and ...
    • Structure-Preserving Reshape for Textured Architectural Scenes 

      Cabral, Marcio; Lefebvre, Sylvain; Dachsbacher, Carsten; Drettakis, George (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Modeling large architectural environments is a difficult task due to the intricate nature of these models and the complex dependencies between the structures represented. Moreover, textures are an essential part of ...

      Peytavie, A.; Galin, E.; Grosjean, J.; Merillou, S. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric ...
    • Range Scan Registration Using Reduced Deformable Models 

      Chang, W.; Zwicker, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning model ...
    • Genuinity Signatures: Designing Signatures for Verifying 3D Object Genuinity 

      Aliaga, Daniel G.; Atallah, Mikhail J. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      3D computer graphics models and digitally-controlled manufacturing have come together to enable the design, visualization, simulation, and automated creation of complex 3D objects. In our work, we propose and implement a ...
    • Linear Time Super-Helices 

      Bertails, Florence (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Thin elastic rods such as cables, phone coils, tree branches, or hair, are common objects in the real world but computing their dynamics accurately remains challenging. The recent Super-Helix model, based on the discrete ...
    • Wrinkling Captured Garments Using Space-Time Data-Driven Deformation 

      Popa, T.; Zhou, Q.; Bradley, D.; Kraevoy, V.; Fu, H.; Sheffer, A.; Heidrich, W. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The presence of characteristic fine folds is important for modeling realistic looking virtual garments. While recent garment capture techniques are quite successful at capturing the low-frequency garment shape and motion ...
    • Shape Decomposition using Modal Analysis 

      Huang, Qi-Xing; Wicke, Martin; Adams, Bart; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We introduce a novel algorithm that decomposes a deformable shape into meaningful parts requiring only a single input pose. Using modal analysis, we are able to identify parts of the shape that tend to move rigidly. We ...
    • A Part-aware Surface Metric for Shape Analysis 

      Liu, Rong; Zhang, Hao; Shamir, Ariel; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The notion of parts in a shape plays an important role in many geometry problems, including segmentation, correspondence, recognition, editing, and animation. As the fundamental geometric representation of 3D objects in ...
    • Out-of-core Data Management for Path Tracing on Hybrid Resources 

      Budge, Brian; Bernardin, Tony; Stuart, Jeff A.; Sengupta, Shubhabrata; Joy, Kenneth I.; Owens, John D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a software system that enables path-traced rendering of complex scenes. The system consists of two primary components: an application layer that implements the basic rendering algorithm, and an out-of-core ...
    • Fast BVH Construction on GPUs 

      Lauterbach, C.; Garland, M.; Sengupta, S.; Luebke, D.; Manocha, D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
