      In this paper, we propose an efficient solution that addresses the performance problems of current single-pass GPU raycasting algorithms. Our paper provides more control over the rendering process by introducing tighter ...
    • Accuracy Evaluation of Different Centerline Approximations of Blood Vessels 

      Cruz, A. La (The Eurographics Association, 2004)
      Accurate determination of the vessel axis is a prerequisite for automated visualization and quantification of artery diseases. This paper presents an evaluation of different methods for approximating the centerline of the ...
    • Acquisition and Display of Real-Time Atmospheric Data on Terrain 

      Jiang, Tian-yue; Ribarsky, William; Wasilewski, Tony; Faust, Nickolas; Hannigan, Brendan; Parry, Mitchell (The Eurographics Association, 2001)
      This paper investigates the integrated acquisition, organization, and display of data from disparate sources, including the display of data acquired in real-time. In this case real-time acquisition and display refers to ...
    • Adaptive Recommendations for Enhanced Non-linear Exploration of Annotated 3D Objects 

      Rodriguez, Marcos Balsa; Agus, Marco; Marton, Fabio; Gobbetti, Enrico (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We introduce a novel approach for letting casual viewers explore detailed 3D models integrated with structured spatially associated descriptive information organized in a graph. Each node associates a subset of the 3D ...
    • Adaptive Smooth Scattered-data Approximation for Large-scale Terrain Visualization 

      Bertram, Martin; Tricoche, Xavier; Hagen, Hans (The Eurographics Association, 2003)
      We present a fast method that adaptively approximates large-scale functional scattered data sets with hierarchical B-splines. The scheme is memory efficient, easy to implement and produces smooth surfaces. It combines ...
    • Adaptive Volume Construction from Ultrasound Images of a Human Heart 

      Reis, Gerd; Bertram, Martin; Lengen, Rolf H. van; Hagen, Hans (The Eurographics Association, 2004)
      We present a volume modelling approach based on sequences of two-dimensional ultrasound images. Though generally applicable to arbitrary freehand ultrasound, our method is designed for the reconstruction of timevarying ...
    • Adaptive Volume Rendering using Fuzzy Logic Control 

      Li, Xinyue; Shen, Han-Wei (The Eurographics Association, 2001)
      This paper presents an automatic error tolerance specification system to control the performance of hierarchical volume rendering. Rather than requiring the user to provide an explicit error tolerance numerically, we let ...
