      This extended abstract details previous methods for motion tracking and capture in 3D animation and in particular that of hand motion tracking and capture. Our research aims to enable gesture capture with interpretation ...
    • HyperStreamball Visualization for Symmetric Second Order Tensor Fields 

      Liu, J.; Turner, M.; Hewitt, W. T.; Perrin, J. S. (The Eurographics Association, 2006)
      This paper proposes a new 3D tensor glyph called a hyperstreamball that extends streamball visualization used within fluid flow fields to applications within second order tensor fields. The hyperstreamball is a hybrid of ...
    • An Interactive Multiscale Framework for Enhancement and Visualization of 2D and 3D Image Data 

      Graham, Andrew D.; Turner, Martin J.; Hewitt, Terry (The Eurographics Association, 2006)
      We present an interactive, multiscale framework for enhancement and de-noising of images and volumes for the purposes of medical image visualization. Among the visualization issues addressed are noise suppression and ...
    • A Mixed Reality Anatomy Teaching Tool 

      Thomas, Rhys G.; John, Nigel W.; Lim, Ik Soo (The Eurographics Association, 2006)
      In this paper we present an inexpensive Mixed Reality software tool for training medical students in anatomy. The software integrates the ARToolkit and Visualization Toolkit (VTK) to create a novel interactive environment ...
    • Out of core Polyhedral Union and its Application to Interactive Shadow Rendering 

      Fedorkiw, J.; Smith, C.; Ghali, S. (The Eurographics Association, 2006)
      Four methods for storing a set of points using a computer are currently known: Boundary representations, Constructive Solid Geometry, Binary Space Partitioning trees, and Nef polyhedra. We describe a time and spaceefficient ...
    • Perceived Rendering Thresholds for High-Fidelity Graphics on Small Screen Devices 

      Aranha, M.; Debattista, K.; Chalmers, A.; Hill, S. (The Eurographics Association, 2006)
      Small screen devices, also known as small-form-factor (SFF) devices including mobile phones and ultra mobile PCs are increasingly ubiquitous. Their uses includes gaming, navigation and interactive visualisation. SFF devices ...
    • Perception-based Lighting Design 

      Ha, Hai Nam; Olivier, Patrick (The Eurographics Association, 2006)
      Perception-based lighting design approaches model image quality using a cognitively grounded objective function which is in turn optimised through manipulation of the lighting parameters of a scene. We present, and ...
    • Physically Based Simulation and Visualization of Fire in Real-Time using the GPU 

      Rødal, Samuel; Storli, Geir; Gundersen, Odd Erik (The Eurographics Association, 2006)
      In this paper we present a physically based framework for real-time simulation and visualization of fire using the GPU. The physics of fire is modeled through a combination of a fluid solver and a combustion process causing ...
    • Polynomial Approximation of Blinn-Phong Model 

      Öztürk, Aydin; Bilgili, Ahmet; Kurt, Murat (The Eurographics Association, 2006)
      The Phong model has been one of the oldest and the most popular reflection models in Computer Graphics. It can be used to model specular highlights of various materials. In this paper, we consider a polynomial model and ...
