We are working to create visualization systems that serve as precision measurement instruments, supporting interactive probing of “samples” to derive quantitative data to enable scientific discovery. We use virtual samples, built from data obtained from either physical measurement or computational simulation.

Our ability to extend measurement science to the virtual world is enabled by advances in the speed and capability of graphics processing units (GPUs). In particular, visualization techniques that employ shaders have the potential to play a central role in measurement and analysis tools within a visualization system because these programs can perform substantial numeric processing within the visualization pipeline where they have direct access to the geometric data describing the objects of study.

Additionally, this allows access to the information needed to determine uncertainties, a prerequisite for precision measurement. This research opportunity focuses all aspects of quantitative visualization, i.e., measurement and analysis applied to visualization objects directly in real-time.
