Bio
Yi-Jen Chiang's main research focus is on developing efficient algorithms for geometric problems in Computer Graphics and Visualization and in Computational Geometry, especially for large datasets. His work is along three major directions toward solving these large-scale problems: out-of-core techniques, simplification and level-of-detail approaches, and compression. He has developed a series of the first out-of-core algorithms for isosurface extraction in scientific visualization that are two orders of magnitude faster than the optimal in-core (main-memory) approach when the dataset is too large to fit in main memory. He also developed the first out-of-core algorithm to support view-dependent simplification and rendering for large polygonal models; this work is the winner of the Best Paper Award of Eurographics 2000. His research is currently supported by several NSF grants, including an NSF CAREER award.
