      Jainek, Werner M.; Born, Silvia; Bartz, Dirk; Straßer, Wolfgang; Fischer, Jan (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Common practice in brain research and brain surgery involves the multi-modal acquisition of brain anatomy and brain activation data. These highly complex three-dimensional data have to be displayed simultaneously in order ...
    • Illustrative Parallel Coordinates 

      McDonnell, Kevin T.; Mueller, Klaus (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Illustrative parallel coordinates (IPC) is a suite of artistic rendering techniques for augmenting and improving parallel coordinate (PC) visualizations. IPC techniques can be used to convey a large amount of information ...
    • Image-based Aging Using Evolutionary Computing 

      Hubball, Daniel; Chen, Min; Grant, Phil W. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Aging has considerable visual effects on the human face and is difficult to simulate using a universally-applicable global model. In this paper, we focus on the hypothesis that the patterns of age progression (and regression) ...

      The appearance manifold [WTL*06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in ...
    • Image-based Shaving 

      Nguyen, Minh Hoai; Lalonde, Jean-Francois; Efros, Alexei A.; De la Torre, Fernando (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many categories of objects, such as human faces, can be naturally viewed as a composition of several different layers. For example, a bearded face with glasses can be decomposed into three layers: a layer for glasses, a ...
    • Image-Based Surface Compression 

      Ochotta, Tilo; Saupe, Dietmar (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a generic framework for compression of densely sampled three-dimensional (3D) surfaces in order to satisfy the increasing demand for storing large amounts of 3D content. We decompose a given surface into patches ...
    • Improving Multipath Radiosity with Bundles of Parallel Lines 

      Martinez, Roel; Sbert, Mateu; Szirmay-Kalos, Laszlo (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Monte Carlo approaches use random lines to distribute the light power in the scene but the cost of creating a set of random single lines is very costly. In this paper, we present several software and hardware techniques ...
    • Interaction-Dependent Semantics for Illustrative Volume Rendering 

      Rautek, Peter; Bruckner, Stefan; Gröller, M. Eduard (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      In traditional illustration the choice of appropriate styles and rendering techniques is guided by the intention of the artist. For illustrative volume visualizations it is difficult to specify the mapping between the 3D ...
    • Interactive Exploratory Visualization of 2D Vector Fields 

      Isenberg, Tobias; Everts, Maarten H.; Grubert, Jens; Carpendale, Sheelagh (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      In this paper we present several techniques to interactively explore representations of 2D vector fields. Through a set of simple hand postures used on large, touch-sensitive displays, our approach allows individuals to ...
    • Interactive Global Illumination for Deformable Geometry in CUDA 

      Schmitz, Arne; Tavenrath, Markus; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive global illumination for fully deformable scenes with dynamic relighting is currently a very elusive goal in the area of realistic rendering. In this work we propose a system that is based on explicit visibility ...
    • Interactive Glossy Reflections using GPU-based Ray Tracing with Adaptive LOD 

      Yu, Xuan; Wang, Rui; Yu, Jingyi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an interactive GPU-based algorithm for accurately rendering high-quality, dynamic glossy reflection effects from both HDR environment maps and local scene objects. Our method uses hardware rasterization to produce ...
    • Interactive Visualization for Memory Reference Traces 

      Choudhury, A. N. M. Imroz; Potter, Kristin C.; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present the Memory Trace Visualizer (MTV), a tool that provides interactive visualization and analysis of the sequence of memory operations performed by a program as it runs. As improvements in processor performance ...
