Thomas A. DeFanti

Thomas Albert "Tom" DeFanti (born September 18, 1948) is an American computer graphics researcher and pioneer. His work has ranged from early computer animation, to scientific visualization, virtual reality, and grid computing. He is a distinguished professor of Computer Science at the University of Illinois at Chicago, and a research scientist at the California Institute for Telecommunications and Information Technology (Calit2).

Education and early life Born September 18, 1948, in Queens, New York City, New York and attended Stuyvesant High School. In 1969, DeFanti received a B.A. in Mathematics from Queens College, and in 1970 he received a M.S. in Computer Information Science from Ohio State University. For his dissertation, he created the GRASS programming language, a three-dimensional, real-time animation system usable by computer novices.

Work In 1973, he joined the faculty of the University of Illinois at Chicago (UIC) and with Daniel J. Sandin, he founded the Circle Graphics Habitat, now known as the Electronic Visualization Laboratory (EVL).

At UIC, DeFanti further developed the GRASS language, and later created an improved version, ZGRASS, implemented on the low-cost Datamax UV-1. Later significant work done at EVL includes development of the graphics system for the Bally Technologies home computer, invention of the first data glove, co-editing the 1987 NSF-sponsored report Visualization in Scientific Computing that outlined the emerging discipline of scientific visualization, invention of PHSColograms, and invention of the CAVE Automatic Virtual Environment. DeFanti's current work includes heading the TransLight/StarLight international multi-gigabit networking project and co-directing the OptIPuter optical networking and visualization project.

DeFanti contributed greatly to the growth of the SIGGRAPH organization and conference. He co-organized early film and video presentations (which became the Electronic Theatre) beginning in 1973, started the SIGGRAPH Video Review archive of computer graphics research in 1979, and served as chair of the group from 1981 to 1985.

DeFanti is a Fellow of the Association for Computing Machinery. He has received the 1988 ACM Outstanding Contribution Award, the 2000 SIGGRAPH Outstanding Service Award, and the UIC Inventor of the Year Award.
