Performance Overview

Performance-related research in the Center concerns a set of enabling technologies that are essential to real-time graphics and visualization, ranging from input to rendering to display. We work on innovative tracking methods for handling user head and hand input, leverage UNC's high-speed graphics engines and other techniques from all the sites to render images faster and more effectively, and develop new 3D displays that provide the proper images to each eye of each user.

The importance of high performance in an interactive system is that it can provide transparency to the user. For example, with high quality rendering delivered by fast graphics engines, a scientist is not distracted by aliasing artifacts while interacting with molecules. With accurate tracking, a physician need not compensate for delayed display updates when moving a transducer during an ultrasound examination. And improving displays, increasing frame rates, reducing lag, and accurately registering objects, allow users to spend more time in a virtual environment without simulator sickness.
