    • Perception of Clones in Forest Rendering 

      Purvis, Alan; Sundstedt, Veronica (The Eurographics Association, 2010)
      The application of instanced clones represents a powerful technique for reducing the time and space requirements of the storage and visualization of large populations of similar objects. This paper presents the results of ...
    • Approximating Poisson Disk Distributions by Means of a Stochastic Dither Array 

      Alford, Jennifer R.; Sheppard, David G. (The Eurographics Association, 2010)
      Achieving blue noise point set distributions has been a common goal of two largely separate research communities: computer graphics and digital halftoning. Computer graphics research has focused largely on geometric solutions ...
    • Real-Time Traffic Simulation Using Cellular Automata 

      Applegate, Christopher S.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2010)
      In this paper, we present a method to simulate large-scale traffic networks, at real-time frame-rates. Our novel contributions include a method to automatically generate a road graph from real-life data, and our extension ...
    • Using Processing to Develop iCove: a Tool for Interactive Coastal Oceanographic Visualization 

      George, Richard L. S. F.; Roberts, Jonathan C.; Davies, Alan G. (The Eurographics Association, 2010)
      We have been developing iCove: the interactive coastal oceanographic visualization environment. The challenge for the ocean scientists is that their models are complex and the datasets that are generated are huge. Furthermore, ...
    • Multiresolution Modeling Using Fractal Image Compression Techniques 

      Belmonte, Óscar; Sancho, Sergio; Ribelles, José (The Eurographics Association, 2010)
      This work presents a new approach to the multiresolution modeling of polygonal meshes. This approach is based on the theoretically well-established fractal image compression techniques. A polygonal mesh is represented as ...
    • Computer Modelling of Theatrical Sets 

      Stephenson, Ian; Pride, Rebecca (The Eurographics Association, 2010)
      Here we discuss the design and implementation of a modelling tool specifically targeted for use by designers of theatrical sets. By applying domain specific knowledge and contraints to the design of the software, we ...
    • Agent-based Large Scale Simulation of Pedestrians With Adaptive Realistic Navigation Vector Fields 

      Karmakham, Twin; Richmond, Paul; Romano, Daniela M. (The Eurographics Association, 2010)
      A large scale pedestrian simulation method, implemented with an agent based modelling paradigm, is presented within this paper. It allows rapid prototyping and real-time modifications, suitable for quick generation and ...
    • An Improved Discrete Level of Detail Model Through an Incremental Representation 

      Ribelles, Jose; López, Angeles; Belmonte, Oscar (The Eurographics Association, 2010)
      Real-time applications such as computer and video games, virtual reality and scientific simulation require rendering of complex models for realism. Graphics rendering engines include multiresolution modelling techniques ...
    • A Thin-plate CAD Mesh Model Splitting Approach Based on Fitting Primitives 

      Geng, Chun; Suzuki, Hiromasa; Yan, Dong-Ming; Michikawa, Takasi; Sato, Yuichi; Hashima, Masayoshi; Ohta, Eiji (The Eurographics Association, 2010)
      Extracting structural information from mesh models is crucial for Simulation Driven Design (SDD) in industrial applications. Focusing on thin-plate CAD mesh models (the most commonly used parts in electronic products such ...
    • Surfel Based Geometry Reconstruction 

      Andersen, Vedrana; Aanæs, Henrik; Bærentzen, Jacob Andreas (The Eurographics Association, 2010)
      We propose a method for retrieving a piecewise smooth surface from noisy data. In data acquired by a scanning process sampled points are almost never on the discontinuities making reconstruction of surfaces with sharp ...
    • Rendering Large Point Datasets with GPU Shaders 

      Aguirre, Hugo; Gutierrez, Diego; Perrin, James S. (The Eurographics Association, 2010)
      This paper demonstrates how programmable GPUs are a powerful tool to display large point datasets at an interactive frame rate. Point datasets are commonly used to analyse and solve complex problems, but rendering them is ...
    • Efficient Image Blur in Web-Based Applications 

      Kraus, Martin (The Eurographics Association, 2010)
      Scripting languages require the use of high-level library functions to implement efficient image processing; thus, real-time image blur in web-based applications is a challenging task unless specific library functions are ...
    • ID-Based Rendering of Silhouettes on GPU 

      Diktas, Engin Deniz; Sahiner, Ali Vahit (The Eurographics Association, 2010)
      When rendering object-silhouettes preprocessing is generally done primarily on the CPU. To this end primitive normals must be made consistent and the silhouette-edges need to be extracted every time the view-point is ...
    • Anisotropic Kuwahara Filtering with Polynomial Weighting Functions 

      Kyprianidis, Jan Eric; Semmo, Amir; Kang, Henry; Döllner, Jürgen (The Eurographics Association, 2010)
      In this work we present new weighting functions for the anisotropic Kuwahara filter. The anisotropic Kuwahara filter is an edge-preserving filter that is especially useful for creating stylized abstractions from images or ...
    • Screen Space Re-Rendering for the Simulation of Concert Lighting 

      Stephenson, Ian; Scanlan, Liam (The Eurographics Association, 2010)
      The visualisation of modern concert lighting requires complex illumination models to be calculated at interactive frame rates. Each light may have 20 or more parameters which are all changing in real time. Here we present ...
