Scientific Visualization: Bridging the Complexity Threshold
Chris Johnson, University of Utah

If we researchers in scientific visualization want our work to be useful in "real world" applications, we must effectively handle the complexity of such systems. In the beginning, computer hardware and algorithms were vastly overwhelmed by such complexity. Over the years, as hardware became faster and algorithms more sophisticated, visualization researchers have created numerous (sometimes even useful) techniques for analyzing data.

For real world applications, one must cross what I think of as a "complexity threshold" in order to have a significant impact within the application domain. Recently, challenged by other researchers facing real-world problems (neurosurgeons requiring assistance with surgical planning, for example), I have had the experience of crossing that threshold for real world applications. This experience only reinforces my belief that visualization will become ever more integral to the scientific discovery and analysis process as we bridge application's complexity thresholds.

In this talk, I will review the state-of-the-art in visualization techniques, discuss their use, both current and potential, in real world applications, and present an outline for a future visualization research agenda.
