    End-to-End Data Reduction and Hardware Accelerated Rendering Techniques for Visualizing Time-Varying Non-uniform Grid Volume Data 

    Akiba, Hiroshi; Ma, Kwan-Liu; Clyne, John (The Eurographics Association, 2005)
    We present a systematic approach for direct volume rendering terascale-sized data that are time-varying, and possibly non-uniformly sampled, using only a single commodity graphics PC. Our method employs a data reduction ...

    A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data 

    Tzeng, Fan-Yin; Ma, Kwan-Liu (The Eurographics Association, 2004)
    In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ...

    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 ...

    The Design and Evaluation of a Pipelined Image Compositing Device for Massively Parallel Volume Rendering 

    Ogata1, Masato; Muraki, Shigeru; Liu, Xuezhen; Ma, Kwan-Liu (The Eurographics Association, 2003)
    An experimental study of software image compositing that we have carried out on a 512-node PC cluster shows the necessity of hardware compositing support to make possible real-time volume visualization scalable with large ...

    Automatic Feature Modeling Techniques for Volume Segmentation Applications 

    Huang, Runzhen; Yu, Hongfeng; Ma, Kwan-Liu; Staadt, Oliver (The Eurographics Association, 2007)
    In many volume segmentation and visualization tasks, the ability to correctly identify the boundary surface of each volumetric feature of interest in the data is desirable. This surface can be used in subsequent quantitative ...

    Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery 

    Wang, Yue; Teoh, Soon Tee; Ma, Kwan-Liu (The Eurographics Association, 2006)
    User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ...

    Natural Visualizations 

    Haroz, Steve; Ma, Kwan-Liu (The Eurographics Association, 2006)
    This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ...

    High-Quality Lighting and Efficient Pre-Integration for Volume Rendering 

    Lum, Eric B.; Wilson, Brett; Ma, Kwan-Liu (The Eurographics Association, 2004)
    Pre-integrated volume rendering is an effective technique for generating high-quality visualizations. The precomputed lookup tables used by this method are slow to compute and can not include truly pre-integrated lighting ...

    High-Quality Rendering of Compressed Volume Data Formats 

    Fout, Nathaniel; Akiba, Hiroshi; Ma, Kwan-Liu; Lefohn, Aaron E.; Kniss, Joe (The Eurographics Association, 2005)
    Rendering directly from packed or compressed volume data formats using graphics hardware has advantages in terms of memory consumption and bandwidth, but results in lower-quality images due to the prohibitive cost of ...

    A Study of Transfer Function Generation for Time-Varying Volume Data 

    Jankun-Kelly, T.J.; Ma, Kwan-Liu (The Eurographics Association, 2001)
    The proper usage and creation of transfer functions for time-varying data sets is an often ignored problem in volume visualization. Although methods and guidelines exist for time-invariant data, little formal study for the ...
