      Feng, Yan; Chen, Yimin (The Eurographics Association, 2006)
      An algorithm for realizing multilayer occlusion in augmented reality (AR) is presented in this paper. We have designed a special scene graph tree comprised of some special nodes, namely EMO nodes. According to the location ...

    • Automatic Stroke Extraction and Stroke Ordering Based on TrueType Font 

      Koo, Sang Ok; Jang, Hyun Gyu; Won, Kwang Hee; Jung, Soon Ki (The Eurographics Association, 2006)
      In this paper, we suggest a method that extracts strokes of Chinese characters and orders them automatically based on glyph data from TrueType Font. TrueType Font contains glyph of characters whose format is a series of ...

    • Collision Detection for Deformable Objects using Octrees 

      Madera, F. A.; Day, A. M.; Laycock, S. D. (The Eurographics Association, 2006)
      We present an algorithm for collision detection between multiple deformable objects translating in a large environment. We use Spatial Partitioning to subdivide the scene and a Bounding Volume Hierarchy to decompose the ...

      Sobottka, Gerrit; Weber, Andreas (The Eurographics Association, 2006)
      We present a framework to study electrical charge phenomena on human hair. We propose a fiber based hair model which bases on the special theory of Cosserat Rods to overcome the well known difficulties one has to deal with ...

    • Curvature-Based Segmentation for Sketch Understanding 

      Zheng, Wentao; Liu, Zhiyu; Sun, Zhengxing (The Eurographics Association, 2006)
      Segmentation is known as an important and fundamental task in sketch understanding, by which free hand drawing is processed into primitive geometric units such as line segments, arcs, etc. Usually, two types of information ...

    • Evolving Body Kinematics for Virtual Characters 

      Gatzoulis, C.; Tang, W.; Stoddart, W. J. (The Eurographics Association, 2006)
      Physically-based character animation systems often require complex knowledge of the underlying equations of motion. Hence, producing physically-realistic animations can be time consuming with these systems. In this paper, ...

    • Expressive and Dynamic Deformation of Animated Computer-Generated Characters 

      Noble, Paul; Tang, Wen (The Eurographics Association, 2006)
      3D computer animated characters often lack the communicative power and the expressiveness of traditional animation, especially when used in non-photorealistic graphical representations. Inspired by a talk by Pixar Animation ...

    • Fast Rendering of Complex Dynamic Scenes 

      Kovalcík, Vit; Sochor, Jiri (The Eurographics Association, 2006)
      We present a novel algorithm capable of rendering complex dynamic scenes at high frame rates. The key part of the algorithm is occlusion culling which is performed by an optimized usage of the hardware occlusion queries. ...

    • Flexible Interaction with Large Point-Based Datasets 

      Rosiuta, A.; Reina, G.; Ertl, T. (The Eurographics Association, 2006)
      We present an application for interacting with large, point-based datasets built with commodity off-the-shelf hardware. Our system works on ordinary workstations with mouse and keyboard interaction as well as on immersive ...

    • GraSSML: Smart Schematic Diagrams, XML and Accessibility 

      Fredj, Z. Ben; Duce, D. A. (The Eurographics Association, 2006)
      This paper describes work in progress at Oxford Brookes University. The project called Graphical Structure Semantic Markup Languages (GraSSML) aims at defining higher-level diagram description languages for the World Wide ...

    • Hand Motion Capture and Tracking in 3D Animation 

      Condell, J.; Moore, G.; Moore, J. (The Eurographics Association, 2006)
      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
