    • Adaptive Sampling in Single Pass, GPU-based Raycasting of Multiresolution Volumes 

      Ljung, Patric (The Eurographics Association, 2006)
      This paper presents a novel direct volume rendering technique for adaptive object- and image-space sampling density of multiresolution volumes. The raycasting is implemented entirely on the GPU in a single pass fragment ...

    • GPU-Accelerated D2VR 

      Xu, Fang; Mueller, Klaus (The Eurographics Association, 2006)
      Traditional volume rendering approaches rely on obtaining values of sampled points in volumetric space, typically on a cartesian grid. Often, this cartesian grid is not the original source of the data. For example, in ...

    • An Image-Based Modelling Approach To GPU-based Unstructured Grid Volume Rendering 

      Shareef, Naeem; Lee, Teng-Yok; Shen, Han-Wei; Mueller, Klaus (The Eurographics Association, 2006)
      Unstructured grid volume rendering on the GPU is an ongoing research goal. The main difficulty is how to map the irregular data efficiently to the graphics hardware. Grid cells cannot be directly processed by the pipeline ...

    • Volumetric Density Capture From a Single Image 

      Fuchs, Christian; Chen, Tongbo; Goesele, Michael; Theisel, Holger; Seidel, Hans-Peter (The Eurographics Association, 2006)
      We propose a new approach to capture the volumetric density of scattering media instantaneously with a single image. The volume is probed with a set of laser lines and the scattered intensity is recorded by a conventional ...

    • Discontinuous Displacement Mapping for Volume Graphics 

      Correa, Carlos D.; Silver, Deborah; Chen, Min (The Eurographics Association, 2006)
      Displacement mapping is commonly used for adding surface details to an object. In this paper, we outline a generalized notion of displacement mapping, which allows for unconventional features such as unorthogonal and ...

    • Multi-Dimensional Transfer Function Design Using Sorted Histograms 

      Lundström, Claes; Ljung, Patric; Ynnerman, Anders (The Eurographics Association, 2006)
      Multi-dimensional Transfer Functions (MDTFs) are increasingly used in volume rendering to produce high quality visualizations of complex data sets. A major factor limiting the use of MDTFs is that the available design tools ...

    • GPU Accelerated Image Aligned Splatting 

      Neophytou, Neophytos; Mueller, Klaus (The Eurographics Association, 2005)
      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 ...

    • iSBVR: Isosurface-aided Hardware Acceleration Techniques for Slice-Based Volume Rendering 

      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) ...

    • A Simple and Flexible Volume Rendering Framework for Graphics-Hardware-based Raycasting 

      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 ...

    • GPU-based Object-Order Ray-Casting for Large Datasets 

      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 ...

    • Robust Generation of Signed Distance Fields from Triangle Meshes 

      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 ...
