    • Efficient Ambient and Emissive Tissue Illumination using Local Occlusion in Multiresolution Volume Rendering 

      Hernell, Frida; Ljung, Patric; Ynnerman, Anders (The Eurographics Association, 2007)
      This paper introduces a novel technique to compute illumination for Direct Volume Rendering. By adding shadow effects to volume rendered images, the perception of shapes and tissue properties can be significantly improved ...

    • Feature Enhancement using Locally Adaptive Volume Rendering 

      Marchesin, Stephane; Dischler, Jean-Michel; Mongenet, Catherine (The Eurographics Association, 2007)
      Classical direct volume rendering techniques accumulate color and opacity contributions using the standard volume rendering equation approximated by alpha blending. However, such standard rendering techniques, often also ...

    • (No) More Marching Cubes 

      Carr, Hamish (The Eurographics Association, 2007)
      Isosurfaces, one of the most fundamental volumetric visualization tools, are commonly rendered using the wellknown Marching Cubes cases that approximate contours of trilinearly-interpolated scalar fields. While a complete ...

    • Palette-Style Volume Visualization 

      Wu, Yingcai; Xu, Anbang; Chan, Ming-Yuen; Qu, Huamin; Guo, Ping (The Eurographics Association, 2007)
      In this paper we propose a palette-style volume visualization interface which aims at providing users with an intuitive volume exploration tool. Our system is inspired by the widely used wheel-style color palette. The ...

    • Quality Enhancement of Direct Volume Rendered Images 

      Chan, Ming-Yuen; Wu, Yingcai; Qu, Huamin (The Eurographics Association, 2007)
      In this paper, we propose a new method for enhancing the quality of direct volume rendered images. Unlike the typical image enhancement techniques which perform transformations in the image domain, we take the volume data ...

    • Simultaneous GPU-Assisted Raycasting of Unstructured Point Sets and Volumetric Grid Data 

      Kaehler, Ralf; Abel, Tom; Hege, Hans-Christian (The Eurographics Association, 2007)
      In the recent years the advent of powerful graphics hardware with programmable pixel shaders enabled interactive raycasting implementations on low-cost commodity desktop computers. Unlike slice-based volume rendering ...

    • Surface Reconstruction from Noisy Point Clouds using Coulomb Potentials 

      Jalba, A.C.; Roerdink, J.B. T.M. (The Eurographics Association, 2007)
      We show that surface reconstruction from point clouds without orientation information can be formulated as a convection problem in a force field based on Coulomb potentials. To efficiently evaluate Coulomb potentials on ...

    • Variational Volumetric Surface Reconstruction from Unorganized Points 

      Jakobsen, Bjarke; Bærentzen, J. Andreas; Christensen, Niels Jørgen (The Eurographics Association, 2007)
      Reconstruction of smooth surfaces from point sets is an important problem in many applications since this sort of data often appear in real-life scenarios. This paper presents method for solving this this problem at ...

    • Volume Deformation via Scattered Data Interpolation 

      Correa, Carlos D.; Silver, Deborah; Chen, Min (The Eurographics Association, 2007)
      With the advent of contemporary GPUs, it has been possible to perform volume deformation at interactive rates. In particular, it has been shown that deformation can be important for the purposes of illustration. In such ...
