Brian A. Barsky is a professor at the University of California, Berkeley, working in computer graphics and geometric modeling as well as in optometry and vision science.
Barsky was a visiting professor at Yale-NUS College in Singapore, in the Department of Computer Graphics and Multimedia in the Faculty of Information Technology at the Brno University of Technology in the Czech Republic, in the Machine Vision and Pattern Recognition Laboratory at the Lappeenranta University of Technology in Finland, at the Laboratoire d'Informatique Fondamentale de Lille (LIFL) of l'Université des Sciences et Technologies de Lille (USTL), at the Hong Kong University of Science and Technology in Hong Kong, at the University of Otago in Dunedin, New Zealand, in the Modélisation Géométrique et Infographie Interactive group at l'Institut de Recherche en Informatique de Nantes and l'Ecole Centrale de Nantes, in Nantes, at the University of Toronto, at the School of Computing at the National University of Singapore, at the Laboratoire Image of l'Ecole Nationale Supérieure des Télécommunications in Paris, and he was a visiting researcher with the Computer Aided Design and Manufacturing Group at the Sentralinsitutt for Industriell Forskning (Central Institute for Industrial Research) in Oslo.
Along with You-Dong Liang, he was an author and namesake of the efficient “Liang-Barsky algorithm” for clipping in computer graphics.
Given the measurements of the optical aberrations of a user’s eye, a vision correcting display produces a transformed image that when viewed by this individual will appear in sharp focus.
This research was selected by Scientific American as one of 2014's ten annual "World Changing Ideas.” Barsky developed a novel contact lens design to help restore vision to people with cornea problems.
