    • A GPU-Supported Lossless Compression Scheme for Rendering Time-Varying Volume Data 

      Mensmann, Jörg; Ropinski, Timo; Hinrichs, Klaus (The Eurographics Association, 2010)
      Since the size of time-varying volumetric data sets typically exceeds the amount of available GPU and main memory, out-of-core streaming techniques are required to support interactive rendering. To deal with the performance ...

    • Efficient Acquisition and Clustering of Local Histograms for Representing Voxel Neighborhoods 

      Meß, Christian; Ropinski, Timo (The Eurographics Association, 2010)
      In the past years many interactive volume rendering techniques have been proposed, which exploit the neighboring environment of a voxel during rendering. In general on-the-fly acquisition of this environment is infeasible ...

    • Advanced Light Material Interaction for Direct Volume Rendering 

      Lindemann, Florian; Ropinski, Timo (The Eurographics Association, 2010)
      In this paper we present a heuristic approach for simulating advanced light material interactions in the context of interactive volume rendering. In contrast to previous work, we are able to incorporate complex material ...

    • Depth-Enhanced Maximum Intensity Projection 

      Díaz, José; Vázquez, Pere-Pau (The Eurographics Association, 2010)
      The two most common methods for the visualization of volumetric data are Direct Volume Rendering (DVR) and Maximum Intensity Projection (MIP). Direct Volume Rendering is superior to MIP in providing a larger amount of ...

    • Feature-Driven Ambient Occlusion for Direct Volume Rendering 

      Ancel, Alexandre; Dischler, Jean-Michel; Mongenet, Catherine (The Eurographics Association, 2010)
      Ambient occlusion techniques were introduced to improve data comprehension by bringing soft fading shadows. They consist in attenuating light by considering the occlusion resulting from the presence of neighboring structures. ...

    • A Survey of Transfer Functions Suitable for Volume Rendering 

      Arens, Stephan; Domik, Gitta (The Eurographics Association, 2010)
      There are many transfer functions (TF) that emphasize or hide special features of volume data. Their potential to cleverly generate a color and opacity value for direct volume rendering is primarily determined by the used ...

    • Multi-dimensional Reduction and Transfer Function Design using Parallel Coordinates 

      Zhao, Xin; Kaufman, Arie (The Eurographics Association, 2010)
      Multi-dimensional transfer functions are widely used to provide appropriate data classification for direct volume rendering. Nevertheless, the design of a multi-dimensional transfer function is a complicated task. In this ...

    • Fast Volumetric Data Exploration with Importance-Based Accumulated Transparency Modulation 

      Wan, Yong; Hansen, Chuck (The Eurographics Association, 2010)
      Direct volume rendering techniques have been successfully applied to visualizing volumetric datasets across many application domains. Due to the sensitivity of transfer functions and the complexity of fine-tuning transfer ...

    • Concurrent Volume Visualization of Real-Time fMRI 

      Nguyen, Tan Khoa; Eklund, Anders; Ohlsson, Henrik; Hernell, Frida; Ljung, Patric; Forsell, Camilla; Andersson, Mats; Knutsson, Hans; Ynnerman, Anders (The Eurographics Association, 2010)
      We present a novel approach to interactive and concurrent volume visualization of functional Magnetic Resonance Imaging (fMRI). While the patient is in the scanner, data is extracted in real-time using state-of-the-art ...

    • Volumetric Evaluation of Meshless Data From Smoothed Particle Hydrodynamics Simulations 

      Jang, Yun; Fuchs, Raphael; Schindler, Benjamin; Peikert, Ronny (The Eurographics Association, 2010)
      As an alternative to conventional Eulerian methods in the field of computational fluid dynamics (CFD), smoothed particle hydrodynamics (SPH) has been developed. Its mesh-free method is useful in problems, especially, where ...

    • Slimming Brick Cache Strategies for Seismic Horizon Propagation Algorithms 

      Gallon, Jonathan; Guillon, Sébastien; Jobard, Bruno; Barucq, Hélène; Keskes, Noomane (The Eurographics Association, 2010)
      In this paper, we propose a new bricked cache system suitable for a particular surface propagation algorithm : seismic horizon reconstruction. The application domain of this algorithm is the interpretation of seismic volumes ...

    • Real-time Surface Analysis and Tagged Material Cleansing for Virtual Colonoscopy 

      Russ, Christoph; Kubisch, Christoph; Qiu, Feng; Hong, Wei; Ljung, Patric (The Eurographics Association, 2010)
      The most common representation of volumetric models is a regular grid of cubical voxels with one value each, from which a smooth scalar field is reconstructed. However, common real-world situations include cases in which ...

    • Split-Voxel: A Simple Discontinuity-Preserving Voxel Representation for Volume Rendering 

      Agus, Marco; Gobbetti, Enrico; Guitián, José Antonio Iglesias; Marton, Fabio (The Eurographics Association, 2010)
      The most common representation of volumetric models is a regular grid of cubical voxels with one value each, from which a smooth scalar field is reconstructed. However, common real-world situations include cases in which ...

    • Wavelet-based Multiresolution Isosurface Rendering 

      Steinberger, Markus; Grabner, Markus (The Eurographics Association, 2010)
      We present an interactive rendering method for isosurfaces in a voxel grid. The underlying trivariate function is represented as a spline wavelet hierarchy, which allows for adaptive (view-dependent) selection of the desired ...

    • Multi-layer Volume Ray Casting on GPU 

      Li, Wei (The Eurographics Association, 2010)
      We present multi-layer volume ray casting that integrates various volume rendering enhancements into a unified framework, including empty-space skipping, volume clipping, embedding opaque and semi-transparent objects, ...

    • A New Sampling Scheme for Slice Based Volume Rendering 

      Krüger, Jens (The Eurographics Association, 2010)
      In this paper we present a novel approach to generate proxy geometry for slice based volume rendering. The basic idea is derived from the behavior of a ray-caster and is a simple extension of the well known 2D object-aligned ...
