    • Scanline Edge-flag Algorithm for Antialiasing 

      Kallio, Kiia (The Eurographics Association, 2007)
      In this paper, a novel algorithm for rendering antialiased 2D polygons is presented. Although such algorithms do exist, they are inefficient when comparing to non-antialiased alternatives. This has lead to a situation where ...

    • Seamless Mesh Stitching Using Curve Approximation 

      Gobeawan, Like; Xu, Shuhong; Turner, Stephen John (The Eurographics Association, 2007)
      Stitching two mesh partitions at their boundaries poses some challenges, especially when a visually seamless result is desired. In general, direct stitching of mismatching mesh boundaries does not readily produce a seamless ...

    • Simulating Film Grain using the Noise-Power Spectrum 

      Stephenson, Ian; Saunders, Arthur (The Eurographics Association, 2007)
      Film grain is an essential part of real images. The artifacts it introduces add character to images, which can otherwise appear too perfect. This paper considers the synthesis of film grain based upon its noise-power ...

    • Speeding Up Isosurfacing: The Matryoshka Algorithm 

      Lopes, Sergio; Lopes, Adriano; Santos, M. Prospero dos (The Eurographics Association, 2007)
      We propose a hybrid algorithm for isosurface visualization that embraces both polygon rendering and direct surface rendering concepts. It uses raytracing to achieve high image quality but avoids the associated empty ray ...

    • Stability Analysis of Filtered Mass-Spring Systems 

      Ahmad, Alexandre; Adly, Samir; Terraz, Olivier; Ghazanfarpour, Djamchid (The Eurographics Association, 2007)
      Mass-spring systems simulations rely on the numerical integration method used for solving the resulting ordinary differential equations. Implicit schemes, which solve such equations, are unconditionally stable and are thus ...

    • A Statistically-Assisted Sketch-Based Interface for Creating Arbitrary 3-dimensional Faces 

      Gunnarsson, Orn; Maddock, Steve (The Eurographics Association, 2007)
      Creating faces is important in a number of application areas. Faces can be constructed using commercial modelling tools, existing faces can be transferred to a digital form using equipment such as laser scanners, and law ...

    • Steering Chemistry in the Right Direction! 

      Davies, R. A. (The Eurographics Association, 2007)
      The development of novel molecular visualization and computational steering applications is described in this paper. Improvements to the Molecular Visualizer application, jointly developed between the schools of Chemistry ...

    • Streaming and Data Enrichment 

      McDerby, Mary J.; Hewitt, William T.; Turner, Martin J. (The Eurographics Association, 2007)
      Data is being created at a continuously increasing rate. Scientists are drowning in their data . So much so they cannot visualize the data to see the big picture. This work-in-progress paper describes a data capture and ...

    • Towards Individualized Ageing Functions for Human Face Images 

      Hunter, David W.; Tiddeman, Bernard P. (The Eurographics Association, 2007)
      We present an overview of work in progress to create ageing functions for the transformation of human face images. Our aims are twofold; Firstly, by extension to three dimensions, the problems of pose and lighting associated ...

    • Using 3D Visualisation in the Repair of Intra-articular Fractures 

      Wilson, A. F.; Musgrove, P. B.; Buckley, K. A.; Pearce, G.; Geoghegan, J. (The Eurographics Association, 2007)
      The overall aim of this work in progress is to use visualisation to provide a tool for pre-operative planning of surgery on complex fractures, in particular for intra-articular fractures. Currently, a patient suffering ...

    • Viewing 0.3Tb Heart Simulation Data At Your Desk 

      Grimstead, I. J.; Kharche, S.; Zhang, H.; Avis, N. J.; Walker, D. W. (The Eurographics Association, 2007)
      Atrial fibrillation (AF) affects a large section of the aged population, accounting for nearly 1% of total National Health Service (NHS) expenditure. Modelling of this condition to promote further understanding is hence ...

    • Visualization Notations, Models and Taxonomies 

      Brodlie, Ken; Noor, Nurul Mohd (The Eurographics Association, 2007)
      Visualization taxonomies are an important means of imposing some structure on a rather diverse field. We review some earlier work in this area, particularly work based on the use of a notation to label classes of visualization ...
