## Research

Along with You-Dong Liang, he was an author and namesake of the “Liang-Barsky algorithm” for clipping in computer graphics.
Barsky created the Beta-spline curve and surface representation which introduced the concept of geometric continuity for smoothness and G$^n$ notation to the fields of computer-aided geometric design and geometric modeling.
He introduced vision-realistic rendering to simulate human vision based on ocular measurements of an individual. Using these measurements, synthetics images are generated. This process modifies input images to simulate the appearance of the scene for the individual.
That work led to an investigation with Fu-Chung Huang of how to display images to compensate for the specific optical aberrations of the viewer, resulting in vision-correcting displays. 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 could impact computer monitors, laptops, tablets, and mobile phones. Vision correction could be provided in some cases where eyeglasses are ineffective. This research was selected by Scientific American as one of 2014's ten annual "World Changing Ideas.”
Barsky developed a contact lens design to help restore vision to people with cornea problems.
