    • Accelerated Deterministic Simulation of X-ray Attenuation Using Graphics Hardware 

      Vidal, Franck; Garnier, M.; Freud, N.; Létang, J.M.; John, N.W. (The Eurographics Association, 2010)
      In this paper, we propose a deterministic simulation of X-ray transmission imaging on graphics hardware. Only the directly transmitted photons are simulated, using the Beer-Lambert law. Our previous attempt to simulate ...

    • Automated Astrophysical Modeling with Shape 

      Wenger, S.; Steffen, W.; Koning, N.; Morisset, C.; Magnor, M. (The Eurographics Association, 2010)
      Three-dimensional models of complex astrophysical objects like galaxies or planetary nebulae have numerous applications in science, education and entertainment. The large distance of these objects, however, makes it difficult ...

    • CAVER Viewer - the explorer of behaviour of tunnels in proteins 

      Kozlíková, Barbora; Sochor, Jirí (The Eurographics Association, 2010)
      Protein exploration in order to discover new medication has been the principal aim of biochemists. In combination with informatics the solution of this task can be faster, more accurate and also more intuitive and ...

    • A curvature based lightning model for quasi-global diffuse illumination 

      Seipel, S.; Liu, F.; Ericsson, M. (The Eurographics Association, 2010)
      In this paper we present extensions to local illumination models that take into account light transport and shadowmasking effects in the neighborhood of the surface point under evaluation. Central to our approach is the ...

    • Efficient Free Path Sampling in Inhomogeneous Media 

      Szirmay-Kalos, László; Tóth, Balázs; Magdics, Milán; Csébfalvi, Balázs (The Eurographics Association, 2010)
      This paper presents an efficient algorithm to sample free path in inhomogeneous participating media. The method is based on the concept of mixing virtual particles to the medium, that complete the extinction coefficient ...

    • Face Fitting using a Genetic Algorithm. 

      Hunter, D.W.; Tiddeman, B. P.; Perrett, D. I. (The Eurographics Association, 2010)
      The ability to estimate the three-dimensional structure of a human face from a single image has many useful applications, including but not limited to the fields of face recognition, modelling and actors head replacement. ...

    • A Framework for Simulation-Event Triggered Animations 

      Hauck, R.; Künzler, U. (The Eurographics Association, 2010)
      We present a generic framework which uses a CAVE virtual environment for the optimization of surgical workflows and operation room medical equipment arrangements. The framework combines an event-driven simulation with 3D ...

    • GPU Destruction: Real-Time Procedural Demolition of Virtual Environments 

      Morris, Derek John; Anderson, Eike Falk (The Eurographics Association, 2010)
      We introduce a method for the real-time simulation of destructible materials for use within videogame environ- ments. Our system combines a number of existing techniques in a Graphics Processing Unit (GPU) based imple- ...

    • A Method for Fast Initialization of Markerless Object Tracking 

      Maiero, Jens; Hinkenjann, Andre (The Eurographics Association, 2010)
      In Mixed Reality (MR) Environments, the user s view is augmented with virtual, artificial objects. To visualize virtual objects, the position and orientation of the user s view or the camera is needed. Tracking of the user ...

    • Procedural Approach for RealisticWoven Fabric Rendering 

      Kim, Sung-Soo; Kang, Young-Min; Namy, Seung-Woo (The Eurographics Association, 2010)
      We present a new procedural method for photorealistic rendering of woven fabric material. The goal of our research is to provide a new procedural method that renders photorealistic woven fabric without any measured data. ...

    • Procedural Generation of Urban Environments through Space and Time 

      Noghani, Jeremy; Liarokapis, Fotis; Anderson, Eike Falk (The Eurographics Association, 2010)
      Although various methods of procedurally generating cities have been proposed in recent years, the problem remains that a user desiring a city from a particular time period or country would have to make time-consuming ...

    • Real-Time Smoke Rendering and Light Interaction 

      Bass, Christopher J.; Anderson, Eike Falk (The Eurographics Association, 2010)
      In computer graphics, smoke can be represented by using particle systems. Adding shadows to particle systems can go a long way to improve visuals and realism. Our work is concerned with external shadows cast onto a particle ...

    • Towards Multi-Touch Map Interaction on Tabletops: State of the Art and Design Recommendations 

      Klompmaker, F.; Ajaj, R. (The Eurographics Association, 2010)
      Since smartphones like the IPhone and larger setups like Microsoft s Surface appeared on the market, the use of multi-touch interaction techniques is wide spread. Multi-touch allows intuitive, easy and fast interaction in ...

    • Undoing Subpixel Rendering for Better Screenshots 

      Loviscach, J. (The Eurographics Association, 2010)
      Subpixel rendering employs the spatial layout of the red, green, and blue slices of a single square pixel on a screen to enhance the horizontal resolution. This method has become the de-facto standard for displaying text. ...
