    Visualization research generates beautiful images and impressive interactive systems. Emphasis on evaluating visualizations is growing. Researchers have successfully used alternative evaluation techniques in human-computer interaction (HCI), including focus groups, field studies, and expert reviews. These methods tend to produce qualitative results and require fewer participants than controlled ex... View full abstract»

    GPUs have evolved into powerful and flexible streaming processors with fully programmable floating-point pipelines and tremendous aggregate computational power and memory bandwidth. With these advances, modern GPUs can now perform more functions than the specific graphics computations for which they were designed. This article describes approaches to using GPU processing power to accelerate tradit... View full abstract»

    Tsunami researchers might soon be able to generate near real-time tsunami simulations before the deadly waves reach vulnerable coastal regions. Within hours after the powerful 2004 Sumatra earthquake set in motion the huge tsunami, several experts produced accurate and detailed computer animations showing how the deadly waves spread through the Indian Ocean and beyond. The combination of precomput... View full abstract»

    We discuss the importance of visualization skills in engineering education and propose a dual approach to helping students improve their spatial abilities. The approach is based on computer graphics applications, and uses both Web-based graphics applications and a sketch-based modeling, system. By combining these approaches, we can capture students' attention and foster two important engineering s... View full abstract»

    The key thesis of this work stipulates that current human-computer interfaces for education and rehabilitation can be greatly improved by recognizing the long-term need for a novel communication layer that can serve as an intermediary between users and today's systems of ever increasing complexity. A special education and rehabilitation system employs real-time interactive computer graphics and ph... View full abstract»

    JHAVE fosters the use of algorithm visualization as an effective pedagogical tool for computer science educators, helping students to better understand algorithms. The Java-hosted algorithm visualization environment (JHAVE) is not an AV system itself but rather a support environment for a variety of AV systems (called AV engines by JHAVE). In broad terms, JHAVE gives such an engine a drawing conte... View full abstract»

    Our interactive, 3D stereo display helps guide clinicians during endovascular procedures, such as intraoperative needle insertion and stent placement relative to the target organs. We describe a new method of guiding endovascular procedures using interactive 3D stereo visualizations. We use as an example the transjugular intrahepatic portosystemic shunt (TIPS) procedure. Our goal is to increase th... View full abstract»

    We take a new approach to interactive visualization and feature detection of large scalar, vector, and multifield computational fluid dynamics data sets that is also well suited for meshless CFD methods. Radial basis functions (RBFs) are used to procedurally encode both scattered and irregular gridded scalar data sets. The RBF encoding creates a complete, unified, functional representation of the ...

    The total list of processing required to view a pixel includes antialiasing, offset sampling, color space projection, reconstruction filter compensation, compositing, gamma correction, and quantization and dithering. If we look at all these operations we can see a pattern: Almost all of them throw away information. When we filter out high frequencies, quantize intensities into bins, project a cont...
