    • Parallel Construction of k-Nearest Neighbor Graphs for Point Clouds 

      Connor, M.; Kumar, P. (The Eurographics Association, 2008)
      We present a parallel algorithm for k-nearest neighbor graph construction that uses Morton ordering. Experiments show that our approach has the following advantages over existing methods: (1) Faster construction of k-nearest ...
    • Pre-Integrated Volume Rendering for Multi-Dimensional Transfer Functions 

      Kraus, M. (The Eurographics Association, 2008)
      This work presents an efficient extension of pre-integrated volume rendering for multi-dimensional transfer functions. Since even two-dimensional transfer functions can result in strong rendering artifacts that cannot be ...
    • Pseudorandom Noise for Real-Time Volumetric Rendering of Fire in a Production System 

      Vanzine, Y.; Vrajitoru, D. (The Eurographics Association, 2008)
      This paper presents an effort at developing a robust, interactive framework for rendering 3D fire in real-time in a production environment. Many techniques of rendering fire in non real-time exist and are constantly employed ...
    • Smooth Mixed-Resolution GPU Volume Rendering 

      Beyer, Johanna; Hadwiger, Markus; Möller, Torsten; Fritz, Laura (The Eurographics Association, 2008)
      We propose a mixed-resolution volume ray-casting approach that enables more flexibility in the choice of downsampling positions and filter kernels, allows freely mixing volume bricks of different resolutions during rendering, ...
    • Stereo Pseudo 3D Rendering for Web-based Display of Scientific Volumetric Data 

      Eng, Daniel Chern-Yeow; Choe, Yoonsuck (The Eurographics Association, 2008)
      Advancement in high-throughput microscopy technology such as the Knife-Edge Scanning Microscopy (KESM) is enabling the production of massive amounts of high-resolution volumetric data of biological microstructures. To fully ...
    • Stroke-Based Transfer Function Design 

      Ropinski, T.; Praßni, J.; Steinicke, F.; Hinrichs, K. (The Eurographics Association, 2008)
      In this paper we propose a user interface for the design of 1D transfer functions. The user can select a feature of interest by drawing one or more strokes directly onto the volume rendering near its silhouette. Based on ...
    • A Survey of Methods for Moving Least Squares Surfaces 

      Cheng, Z.-Q.; Wang, Y.-Z.; Li, B.; Xu, K.; Dang, G.; Jin, S.-Y. (The Eurographics Association, 2008)
      Moving least squares (MLS) surfaces representation directly defines smooth surfaces from point cloud data, on which the differential geometric properties of point set can be conveniently estimated. Nowadays, the MLS surfaces ...
