    Splatting is a popular technique for volume rendering, where voxels are represented by Gaussian kernels, whose pre-integrated footprints are accumulated to form the image. Splatting has been mainly used to render pre-shaded ...
  • Xue, Daqing; Zhang, Caixia; Crawfis, Roger (The Eurographics Association, 2005)
    In this paper, we examine the performance of the early z-culling feature on current high-end commodity graphics cards and present an isosurface-aided hardware acceleration algorithm for slice-based volume rendering (iSBVR) ...
  • Hong, Wei; Qiu, Feng; Kaufman, Arie (The Eurographics Association, 2005)
    We propose a GPU-based object-order ray-casting algorithm for the rendering of large volumetric datasets, such as the Visible Human CT datasets. A volumetric dataset is decomposed into small sub-volumes, which are then ...
  • Stegmaier, Simon; Strengert, Magnus; Klein, Thomas; Ertl, Thomas (The Eurographics Association, 2005)
    In this work we present a flexible framework for GPU-based volume rendering. The framework is based on a single pass volume raycasting approach and is easily extensible in terms of new shader functionality. We demonstrate ...
  • Bærentzen, J. Andreas (The Eurographics Association, 2005)
    A new method for robust generation of distance fields from triangle meshes is presented. Graphics hardware is used to accelerate a technique for generating layered depth images. From multiple layered depth images, a binary ...
  • Uesu, Dirce; Bavoil, Louis; Fleishman, Shachar; Shepherd, Jason; Silva, Cláudio T. (The Eurographics Association, 2005)
    Tetrahedral meshes are widely used in scientific computing for representing three-dimensional scalar, vector, and tensor fields. The size and complexity of some of these meshes can limit the performance of many visualization ...
  • Yang, Chuan-Kai; Chiueh, Tzi-Cker (The Eurographics Association, 2005)
    Very large irregular-grid volume data sets are typically represented as tetrahedral mesh and require substantial disk I/O and rendering computation. One effective way to reduce this demanding resource requirement is ...
  • Takeshima, Yuriko; Takahashi, Shigeo; Fujishiro, Issei; Nielson, Gregory M. (The Eurographics Association, 2005)
    Recent development in the design of multi-dimensional transfer functions allows us to automatically generate comprehensible visualization images of given volumes by taking into account local features such as differentials ...
  • Miller, Chris M.; Jones, Mark W. (The Eurographics Association, 2005)
    Texture mapping is an extremely powerful and flexible tool for adding complex surface detail to an object. This paper introduces a method of surface texturing and hypertexturing complex volumetric objects in real-time. We ...
  • Novotný, Pavol; Srámek, Milos (The Eurographics Association, 2005)
    We present a new approach for voxelization of implicit solids which contain sharp details. If such objects are processed by common techniques, voxelization artifacts may appear, resulting, among others, in jaggy edges in ...
  • Chen, Min (The Eurographics Association, 2005)
    This paper describes an extension to the technical framework of Constructive Volume Geometry (CVG) in order to accommodate point clouds in volume scene graphs. It introduces the notion of point-based volume object (PBVO) ...
  • Zhang, Caixia; Xue, Daqing; Crawfis, Roger; Wenger, Rephael (The Eurographics Association, 2005)
    In this paper, we study the interval segmentation and direct rendering of time-varying volumetric data to provide a more effective and interactive volume rendering of time-varying structured and unstructured grids. Our ...
  • Li, Shengying; Mueller, Klaus (The Eurographics Association, 2005)
    We present an efficient framework for the high-quality rendering of discretely sampled surface-based objects with refractive effects. This requires an accurate estimation of the refraction coefficients, paired with efficient ...
  • Sharp, Richard; Machiraju, Raghu (The Eurographics Association, 2005)
    In recent years there has been considerable interest in modeling realistic subsurface light scattering in materials such as marble, human skin, or clouds. Many of these models provide a solution for the transport equation ...
  • Ghosh, Abhijeet; Trentacoste, Matthew; Heidrich, Wolfgang (The Eurographics Association, 2005)
    Dynamic range restrictions of conventional displays limit the amount of detail that can be represented in volume rendering applications. However, high dynamic range displays with contrast ratios larger than 50;000 : 1 have ...
  • Ahrenberg, Lukas; Ihrke, Ivo; Magnor, Marcus (The Eurographics Association, 2005)
    Lately, new methods for the acquisition of time-varying, volumetric data for photo-realistic rendering of semitransparent, volumetric phenomena like fire and smoke have been developed. This paper presents a wavelet-coding ...
  • Ryan, John; O Sullivan, Carol; Bell, Christopher; Mulvihill, Niall (The Eurographics Association, 2005)
    We have developed a software system that takes standard electrocardiogram (ECG) input and interprets this input along with user-defined and automatically defined markers to diagnose myocardial infarctions (MI). These ...
  • Bartz, Dirk; Lakare, Sarang (The Eurographics Association, 2005)
    The coronary arteries are essential for the proper function of the human heart. However, they are generally difficult to segment in volume datasets separately from the other blood-filled cavities of the heart. The major ...
  • Wang, Aaron S.; Narayan, Girish; Kao, David; Liang, David (The Eurographics Association, 2005)
    The enthusiasm for novel, minimally invasive, catheter based intracardiac procedures has highlighted the need to provide accurate, real-time, anatomically based image guidance to decrease complications, improve precision, ...
  • Akiba, Hiroshi; Ma, Kwan-Liu; Clyne, John (The Eurographics Association, 2005)
    We present a systematic approach for direct volume rendering terascale-sized data that are time-varying, and possibly non-uniformly sampled, using only a single commodity graphics PC. Our method employs a data reduction ...
