    • Interactive Character Animation using Simulated Physics 

      Geijtenbeek, Thomas; Pronost, Nicolas; Egges, Arjan; Overmars, Mark H. (The Eurographics Association, 2011)
      Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as rigid objects, fluids, cloths and rag-doll ...

    • Using Procedural Modelling as a Framework for Representing Style: An Example from Regency Architecture 

      Calogero, Erica; Tyson, Nick; Arnold, David; Morris, David (The Eurographics Association, 2011)
      This paper reports the use of shape grammars, as made available in CityEngine, to deconstruct six examples of Regency facades and uses them to form a reconstruction of Brunswick Square, in Brighton & Hove, UK. The aim of ...

    • Accelerated 5D Ray Tree construction on the GPU 

      Kammaje, Ravi P.; Mora, Benjamin (The Eurographics Association, 2011)
      Ray tracing random rays has been a challenge. Due to their reduced coherence, the normal methods of acceleration like packet tracing that make use of coherence of the rays do not work well. These random rays are encountered ...

    • Discovery of Intrinsic Primitives on Triangle Meshes 

      Solomon, Justin; Ben-Chen, Mirela; Butscher, Adrian; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The discovery of meaningful parts of a shape is required for many geometry processing applications, such as parameterization, shape correspondence, and animation. It is natural to consider primitives such as spheres, ...

    • GPU Based On-the-fly Light Emission-absorption Approximation for Direct Multi-volume Rendering 

      Khlebnikov, Rostislav; Kainz, Bernhard; Roth, Bernhard; Muehl, Judith; Schmalstieg, Dieter (The Eurographics Association, 2011)
      We present a novel on-the-fly scatter approximation scheme that can be applied concurrently to multiple volumetric datasets. We use a simplified version of the emission-absorption model, including single scattering and ...

    • SQuad: Compact Representation for Triangle Meshes 

      Gurung, Topraj; Laney, Daniel; Lindstrom, Peter; Rossignac, Jarek (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The SQuad data structure represents the connectivity of a triangle mesh by its "S table" of about 2 rpt (integer references per triangle). Yet it allows for a simple implementation of expected constant-time, random-access ...

    • The Worst View for Virtual Museum Presentation 

      Varhanikova, I.; Ferko, A. (The Eurographics Association, 2011)
      We discuss the possibility of the worst view utilization in virtual environment (especially virtual museum). Our approach uses one of the possible method of finding the best view on virtual 3D objects. We use the junky ...

    • Computational Plenoptic Imaging 

      Wetzstein, Gordon; Ihrke, Ivo; Lanman, Douglas; Heidrich, Wolfgang (The Eurographics Association, 2011)
      The plenoptic function is a ray-based model for light that includes the color spectrum as well as spatial, temporal, and directional variation. Although digital light sensors have greatly evolved in the last years, one ...

    • Combinatorial Bidirectional Path-Tracing for Efficient Hybrid CPU/GPU Rendering 

      Pajot, Anthony; Barthe, Loïc; Paulin, Mathias; Poulin, Pierre (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents a reformulation of bidirectional path-tracing that adequately divides the algorithm into processes efficiently executed in parallel on both the CPU and the GPU. We thus benefit from high-level optimization ...

    • Interactive Modeling of City Layouts using Layers of Procedural Content 

      Lipp, Markus; Scherzer, Daniel; Wonka, Peter; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we present new solutions for the interactive modeling of city layouts that combine the power of procedural modeling with the flexibility of manual modeling. Procedural modeling enables us to quickly generate ...

    • Alpha Compression with Variable Data Formats 

      Jiang, Yifei; Gui, Mindan; Chen, Shuai; Hu, Weiwu (The Eurographics Association, 2011)
      Based on the insight into the essential differences between transparency and color, we present a novel alpha compression scheme, called EAC (Enhanced Alpha Compression), as an improvement to that of DXT5. EAC defines new ...

    • Architectural Styles Dependent Shape Grammar Representation of Facades 

      Duskova, E.; Zara, J. (The Eurographics Association, 2011)
      In this poster, we present an idea to utilize formal rules and descriptions for architectural styles from various time periods. We focus on facades of historical buildings with identical purpose located in a specific ...

    • Freehand HDR Imaging of Moving Scenes with Simultaneous Resolution Enhancement 

      Zimmer, Henning; Bruhn, Andrés; Weickert, Joachim (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Despite their high popularity, common high dynamic range (HDR) methods are still limited in their practical applicability: They assume that the input images are perfectly aligned, which is often violated in practise. Our ...
