  • 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 ...

  • 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 ...

  • 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 ...

  • Visualizing a Spherical Geological Discrete Element Model of Fault Evolution 

    Longshaw, Stephen M.; Turner, Martin J.; Finch, Emma (The Eurographics Association, 2012)
    Discrete Element Modelling (DEM) is a numerical technique that uses a system of interacting discrete bodies to simulate the movement of material being exposed to external forces. This technique is often used to simulate ...

  • 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 ...

  • 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 ...

  • 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 ...

  • ViewFusion: Correlating Structure and Activity Views for Execution Traces 

    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 ...

  • 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 ...

  • 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 ...

  • 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)
    This paper presents a novel desktop virtual reality model titled Virtual Electrical Services (VES), developed to en-hance electrical safety and design in the built environment. The model developed using Quest3D has the ...

  • 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 ...
