Manuel Menezes de Oliveira Neto (Assistant Professor). He received a BS in Computer Science, an MS in Computer Science from the Federal University of Rio Grande do Sul (UFRGS), Brazil, in 1992, and a Ph.D. in Computer Science from the University of North Carolina at Chapel Hill in 2000. Before joining the Faculty of the Computer Science Department at UFRGS, Dr. Oliveira worked for two years as an Assistant Professor of Computer Science at the State University of New York at Stony Brook. His research interests are in computer graphics, computer vision and image processing, with emphasis on image-based modeling and rendering, interactive 3-D graphics and virtual environments. His research focuses on ways to combine the photo-realistic promise of image-based modeling and rendering techniques with the advantages of polygonal rendering. For this, he has created algorithms that allow texture mapping to support the representation of 3-D surface detail and view motion parallax. He is currently exploring ways to model and render realistic virtual environments from data scanned from real environments.
