    • Pixel-Level Algorithms for Drawing Curves 

      Liu, Yong Kui; Wang, Peng Jie; Zhao, Dan Dan; Spelic, Denis; Mongus, Domen; Zalik, Borut (The Eurographics Association, 2011)
      This paper introduces new pixel level algorithms for parametric curves. The optimal value of the steps is first derived when rastrerizing parametric curves. A double-step algorithm using only integer arithmetic is presented ...

    • Remodelling of Botanical Trees for Real-Time Simulation 

      Reynolds, Daniel T.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2011)
      This paper proposes a technique to use virtual trees created with an industry recognised modelling tool. Initially the skeletal structure is extracted and processed to generate a continuous mesh suitable for high quality, ...

    • Simple and Efficient Normal Encoding with Error Bounds 

      Schinko, Christoph; Ullrich, Torsten; Fellner, Dieter W. (The Eurographics Association, 2011)
      Normal maps and bump maps are commonly used techniques to make 3D scenes more realistic. Consequently, the efficient storage of normal vectors is an important task in computer graphics. This work presents a fast, lossy ...

    • Terrain Models for Mass Movement Erosion 

      Hudák, Matej; Durikovic, R. (The Eurographics Association, 2011)
      In this paper we present a particle-based method for large scale long time progressive simulation of terrain erosion containing wet granular particles. The wetting process and the propagation through granular material is ...

    • Visual Saliency for Smell Impulses and Application to Selective Rendering 

      Harvey, Carlo; Bashford-Rogers, Thomas E. W.; Debattista, Kurt; Chalmers, Alan (The Eurographics Association, 2011)
      A major challenge in generating high-fidelity virtual environments is to be able to provide interactive rates of realism. However this is very computationally demanding and only recently visual perception has been used in ...

    • Visualisation of Blockplay in Early Childhood 

      Albin-Clark, Adrian; Howard, T. L. J.; Anderson, B. (The Eurographics Association, 2011)
      Observation of young children is common in educational settings. For trainee practitioners however, access to children is infrequent, and even then, only small amounts of observable activity can be captured. We have developed ...
