Research in this area explores data visualization, non-photorealistic renderings, and perception in virtual environments. It draws from and contributes to work in algorithms, human perception, art, animation, computer vision, and image processing. Specific research thrusts in the department include information visualization, visualization of 2-D and 3-D flow data, multivariate visualization, non-photorealistic rendering, volume visualization, point based modeling and rendering, physically and perceptually-based image synthesis, color appearance design and reproduction, and the investigation of perceptual issues in virtual environments.
