      Trümper, Jonas; Telea, Alexandru; Döllner, Jürgen (The Eurographics Association, 2012)
      Visualization of data on structure and related temporal activity supports the analysis of correlations between the two types of data. This is typically done by linked views. This has shortcomings with respect to efficient ...

    • Large Scale Pedestrian Multi-Simulation for a Decision Support Tool 

      Karmakharm, Twin; Richmond, Paul (The Eurographics Association, 2012)
      Ability to simulate pedestrian behaviour on a large scale is essential in identifying potential dangers in public spaces during an evacuation. Multiple designs must be tested with varying parameters and run multiple times ...

      We present a user-driven reconstruction system for the creation of 3D models of buildings from photographs. The structural properties of buildings, such as parallel and repeated elements, are used to allow the user to ...

    • Path Tracing on Massively Parallel Neuromorphic Hardware 

      Richmond, Paul; Allerton, David J. (The Eurographics Association, 2012)
      Ray tracing on parallel hardware has recently benefit from significant advances in the graphics hardware and associated software tools. Despite this, the SIMD nature of graphics card architectures is only able to perform ...

    • Physical and Perceptual Limitations of a Projector-based High Dynamic Range Display 

      Wanat, Robert; Petit, Josselin; Mantiuk, Rafal (The Eurographics Association, 2012)
      High dynamic range (HDR) displays capable of reproducing scenes of high luminance (exceeding 2,000 cd/m2) and contrast (more than 10,000:1) are a useful tool for research on visual performance, image quality or colour ...

    • Light Clustering for Dynamic Image Based Lighting 

      Staton, Sam; Debattista, Kurt; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2012)
      High Dynamic Range (HDR) imagery has made it possible to relight virtual objects accurately with the captured lighting. This technique, called Image Based Lighting (IBL), is a commonly used to render scenes using real-world ...

    • Backwards Compatible JPEG Stereoscopic High Dynamic Range Imaging 

      Selmanovic, Elmedin; Debattista, Kurt; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2012)
      In this paper we introduce Stereoscopic High Dynamic Range (SHDR) Imagery which is a novel tecnique that combines high dynamic range imaging and stereoscopy. Stereoscopic imaging captures two images representing the views ...

    • Enabling Visualization of Massive Datasets Through MPP Database Architecture 

      Al-Naser, Aqeel; Rasheed, Masroor; Brooke, John; Irving, Duncan (The Eurographics Association, 2011)
      We are developing a novel visualization architecture which is specifically designed to render very large (terabyte scale) datasets. Our method differs from the classic visualization pipeline of Harber and McNabb. In ...

    • Compositing Shaders in X3D 

      Kamburelis, Michalis (The Eurographics Association, 2011)
      We present a new approach for implementing effects using the GPU shading languages. Our effects seamlessly cooperate with each other and with the shaders used internally by the 3D application. Thus the effects are reusable, ...

    • Evaluation of a Reconfigurable Tangible Device for Collaborative Manipulation of Objects in Virtual Reality 

      Aguerreche, Laurent; Duval, Thierry; Lécuyer, Anatole (The Eurographics Association, 2011)
      In this paper we introduce an evaluation of a Reconfigurable Tangible Device (RTD) for collaborative manipulation of objects in virtual environments. The considered RTD, called RTD-3, has a triangular shape that naturally ...

    • A Desktop Multi-Touch Interface for Posing Characters 

      Stephenson, Ian (The Eurographics Association, 2011)
      Multi-touch, direct manipulation interfaces have become common in mobile media applications, but their use on the desktop is limited. In this paper we propose that multi touch direct manipulation is well suited to the ...
