    • An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation 

      Simnett, Timothy J. R.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2009)
      Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ...

    • Visual Representation of Multiple Associations in Data using Constrained Graph Layout 

      Xu, Weijia; Sreevalsan-Nair, Jaya (The Eurographics Association, 2009)
      This paper presents a new approach for simultaneously visualizing multiple exclusive associations, defined on the same dataset, using constrained graph layout. We work with two different associations at a time, which can ...

    • Automatically Generating Virtual Humans using Evolutionary Algorithms 

      Albin-Clark, Adrian; Howard, Toby (The Eurographics Association, 2009)
      Abstract Virtual Humans are used in many applications either as an embodiment of a real person (an "avatar"), or under the control of a computer program (an "agent" or "non-player character"). The automatic generation of ...

    • Object Interaction Using Tabulated Spheres Subsets 

      Newball, Andres A. Navarro; Wyvill, Geoff; McCane, Brendan (The Eurographics Association, 2009)
      Tabulated Sphere Subsets (TSSs) provide a fast way to approximate collision tests between objects whose motion is constrained. A TSS is a subset of a set of spheres that approximate the shape of two objects that might ...

    • Distance Based Feature Detection on 3D Point Sets 

      Ramli, Ahmad; Ivrissimtzis, Ioannis (The Eurographics Association, 2009)
      We propose a distance based algorithm for implicit feature detection on 3D point sets. Instead of directly determining whether a point belongs to a feature of the 3D point set or not, we first compute the distance between ...

    • An Adaptive Sampling Approach to Incompressible Particle-Based Fluid 

      Hong, Woosuck; House, Donald H.; Keyser, John (The Eurographics Association, 2009)
      We describe an adaptive particle-based technique for simulating incompressible fluid that uses an octree structure to compute inter-particle interactions and to compute the pressure field. Our method extends the hybrid ...

    • Accelerating Raycasting Utilizing Volume Segmentation of Industrial CT Data 

      Frey, Steffen; Ertl, Thomas (The Eurographics Association, 2009)
      We propose a flexible acceleration technique for raycasting targeted at industrial CT data and the context of material deficiency checking. Utilizing volume segmentation that is typically employed for object analysis, GPU ...

    • Texture Classification using Fractal Geometry for the Diagnosis of Skin Cancers 

      Blackledge, J. M.; Dubovitskiy, D. A. (The Eurographics Association, 2009)
      We present an approach to object detection and recognition in a digital image using a classification method that is based on the application of a set of features that include fractal parameters such as the Lacunarity and ...

    • Interactive Relighting for Stage Use 

      Stephenson, Ian (The Eurographics Association, 2009)
      Re-lighting by combining images taken under known lighting conditions to synthesise new lighting configurations is a simple, but powerful technique capable of producing impressive results. However it has found little ...

    • Multimodal Visualization with Interactive Closeups 

      Ropinski, Timo; Viola, Ivan; Biermann, Martin; Hauser, Helwig; Hinrichs, Klaus (The Eurographics Association, 2009)
      Abstract Closeups are used in illustrations to provide detailed views on regions of interest. They are integrated into the rendering of the whole structure in order to reveal their spatial context. In this paper we present ...

    • A Haptic System for Drilling into Volume Data with Polygonal Tools 

      Liu, Yu; Laycock, Stephen D. (The Eurographics Association, 2009)
      With the developments of volume visualization technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ...

    • Simulation of X-ray Attenuation on the GPU 

      Vidal, Franck; Garnier, Manuel; Freud, Nicolas; Létang, Jean Michel; John, Nigel W. (The Eurographics Association, 2009)
      In this paper, we propose to take advantage of computer graphics hardware to achieve an accelerated simulation of X-ray transmission imaging, and we compare results with a fast and robust software-only implementation. The ...

    • An Improved Precise Multi-contact Haptic Visualization 

      Flasar, Jan; Kovalcík, Vít; Sochor, Jirí (The Eurographics Association, 2009)
      We present an improved multi-contact haptic visualization method based on the Spatialized Normal Cone Hier- archies (SNCH). Though this approach is not entirely new, we have implemented several improvements in order to ...
