    • Advanced, Automatic Stream Surface Seeding and Filtering 

      Edmunds, Matt; Laramee, Robert S.; Chen, Guoning; Zhang, Eugene; Max, Nelson (The Eurographics Association, 2012)
      The placement or seeding of stream surfaces in 3D flow fields faces a number of challenges. These challenges include perception, occlusion, and the appropriate representation of flow characteristics. A variety of streamline ...
    • Analyzing and Visualizing Multivariate Volumetric Scalar Data and Their Uncertainties 

      Ma, Ji; Murphy, D.; O'Mathuna, C.; Hayes, M.; Provan, G. (The Eurographics Association, 2012)
      Data sets from the real world and most scientific simulations are known to be imperfect, often incorporating uncertainty information. Exploration and analysis of such variable data can lead to inaccurate or even incorrect ...
    • 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 ...
    • Computing Curve Skeletons from Medial Surfaces of 3D Shapes 

      Telea, Alexandru; Jalba, Andrei C. (The Eurographics Association, 2012)
      Skeletons are powerful shape descriptors with many applications in shape processing, reconstruction and matching. In this paper we show that in 3D, curve skeletons can be extracted from surface skeletons in the same manner ...
    • Fast Scalable k-NN Computation for Very Large Point Clouds 

      Spina, Sandro; Debattista, Kurt; Bugeja, Keith; Chalmers, Alan (The Eurographics Association, 2012)
      The process of reconstructing virtual representations of large real-world sites is traditionally carried out through the use of laser scanning technology. Recent advances in these technologies led to improvements in precision ...
    • Hardware Accelerated Medical Data Visualisation on the Web 

      Wei, Hui; Clapworthy, Gordon J.; Liu, E.; Zhao, Y.; McFarlane, N. M. B. (The Eurographics Association, 2012)
      This paper proposes a way to develop high-quality real-time web-based medical 3D data visualisation. Isosurface extraction is used as an example to discuss how to use programmable Graphics Processing Units (GPUs) and shaders ...
    • 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 ...
    • 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 ...
    • On the Fractal Behaviour of AA Patterns 

      Ahmed, Abdalla G. M. (The Eurographics Association, 2012)
      ''AA Patterns'' is a recently discovered kind of algorithmic art in the form of pixel patterns; where each pixel in a 2D bitmap is set or unset according to a simple test applied to its coordinates pair. In spite of their ...
    • 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 ...
    • Simplified User Interface for Architectural Reconstruction 

      Wanner, Fabian; Pece, Fabrizio; Kautz, Jan (The Eurographics Association, 2012)
      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 ...
    • Using Quest3D to Develop VES: a Tool for Enhancing Electrical Safety and Design in the Built Environment 

      Barrett, Martin; Blackledge, J. M. (The Eurographics Association, 2012)
