The Institute for Data Analysis and Visualization (IDAV) consists of six faculty members and approximately 30 researchers and graduate students all working on interdisciplinary problems in visualization, geometric modeling, computer graphics, computational geometry, graphics architecture, and immersive technologies. We are key partners in SDAV, a DoE SciDAC III Scalable Data Analysis an Visualization Center, and in the IRTG, an International Research Training Group based at the Technical University of Kaiserslautern in Germany. We are an internationally recognized leader in the fields of visualization and computer graphics, addressing problems that range from the multiresolution display of very large-scale data, to the discovery of new visual analysis algorithms, to the design of methods to accelerate the use of graphics hardware.

Bicubic Subdivision Surface Wavelets
Martin Bertram, Mark A. Duchaineau, Bernd Hamann, Ken Joy

In this project, we have constructed a new wavelet transform based on uniform bicubic B-spline subdivision. Our approach is the first to use a simple lifting-style filtering operation with bicubic precision. Compared to the previous smooth subdivision-surface wavelets constructions, our approach requires only fast and local lifting-style filtering operations rather than global sparse ... [more]
