    • Hybrid Forward Resampling and Volume Rendering 

      Yuan, Xiaoru; Nguyen, Minh X.; Xu, Hui; Chen, Baoquan (The Eurographics Association, 2003)
      The transforming and rendering of discrete objects, such as traditional images (with or without depths) and volumes, can be considered as resampling problem - objects are reconstructed, transformed, filtered, and finally ...

    • Integrating Pre-Integration Into The Shear-Warp Algorithm 

      Schulze, J.P.; Kraus, M.; Lang, U.; Ertl, T. (The Eurographics Association, 2003)
      The shear-warp volume rendering algorithm is one of the fastest algorithms for volume rendering, but it achieves this rendering speed only by sacrificing interpolation between the slices of the volume data. Unfortunately, ...

    • An Interactive Volume Visualization System for Transient Flow Analysis 

      Rosa, Gabriel G.; Lum, Eric B.; Ma, Kwan-Liu; Ono, Kenji (The Eurographics Association, 2003)
      This paper describes the design and performance of an interactive visualization system developed specifically for improved understanding of time-varying volume data from thermal flow simulations for vehicle cabin and ...

    • Multiresolution Volume Simplification and Polygonization 

      Zhang, Nan; Kaufman, Arie (The Eurographics Association, 2003)
      We propose a multiresolution volume simplification and polygonization algorithm. Traditionally, voxel-based algorithms lack the adaptive resolution support and consequently simplified volumes quickly lose sharp features ...

    • OpenVL - The Open Volume Library 

      Lakare, Sarang; Kaufman, Arie (The Eurographics Association, 2003)
      OpenVL is a modular, extensible, and high performance library for handling volumetric datasets. It provides a standard, uniform, and easy to use API for accessing volumetric data. It allows the volumetric data to be laid ...

    • Out-of-Core Encoding Of Large Tetrahedral Meshes 

      Ueng, Shyh-Kuang (The Eurographics Association, 2003)
      In this paper, an out-of-core data compression method is presented to encode large Finite Element Analysis (FEA) meshes. The method is comprised with two stages. At the first stage, the input FEA mesh is divided into blocks, ...

    • Rapid Emission Tomography Reconstruction 

      Chidlow, Ken; Möller, Torsten (The Eurographics Association, 2003)
      We present new implementations of the Maximum Likelihood Expectation Maximization (EM) algorithm and the related Ordered Subset EM (OSEM) algorithm. Our implementation is based on modern graphics hardware and achieves ...

    • Real-Time Volume Manipulation 

      Singh, V.; Silver, D.; Cornea, N. (The Eurographics Association, 2003)
      In this paper, we describe a set of algorithms and an implementation (called VolEdit), for interactively manipulating 3D volumetric objects (datasets). The system utilizes skeletons, which allows users/animators to ...

    • Remote View-dependent Isosurface Visualization 

      Liu, Zhiyan; Li, Kai (The Eurographics Association, 2003)
      This paper presents a simple and effective protocol for remote isosurface visualization. The protocol breaks up the isosurface visualization pipeline at the 3D primitive stage for the server to send primitives to the client. ...

    • Spatial Transfer Functions - A Unified Approach to Specifying Deformation in Volume Modeling and Animation 

      Chen, M.; Silvery, D.; Winter, A. S.; Singhy, V.; Cornea, N. (The Eurographics Association, 2003)
      In this paper, we introduce the concept of spatial transfer functions as a unified approach to volume modeling and animation. A spatial transfer function is a function that defines the geometrical transformation of a scalar ...

    • Volume CAD 

      Kase, K.; Teshima, Y.; Usami, S.; Ohmori, H.; Teodosiu, C.; Makinouchi, A. (The Eurographics Association, 2003)
      With the transition of the most fundamental data in manufacturing from drawings to three-dimensional (3D) CAD (Computer Aided Design) data, we are now able to fabricate products with beautiful curved surfaces, for example, ...

    • A Volume Rendering Approach for Sea Surfaces Taking into Account Second Order Scattering Using Scattering Maps 

      Iwasaki, Kei; Dobashi, Yoshinori; Nishita, Tomoyuki (The Eurographics Association, 2003)
      We present a fast volume rendering technique for sea surfaces taking into account second order scattering using graphics hardware. To generate realistic images of the sea surfaces, accurate simulation of light transport ...

    • Volumetric Ablation Rendering 

      Varadhan, Hari; Mueller, Klaus (The Eurographics Association, 2003)
      In this paper, we propose a physically-based method for simulating the process of ablation on volumetric models. We demonstrate the visual effect of ablative processes, such as a beam of heat emitted from a blow torch or ...
