Brigham Young University Professor to Receive 2006 Achievement Award

June 20, 2006

NEW YORK — ACM SIGGRAPH will award its 2006 Computer Graphics Achievement Award to Thomas W. Sederberg for his contributions to free-form deformation (FFD) and the use of algebraic geometry in geometric modeling. The Computer Graphics Achievement award is given each year for outstanding achievement in computer graphics and interactive techniques. Sederberg, a professor in the Computer Science Department at Brigham Young University, and associate dean of BYU's College of Physical and Mathematical Sciences, will receive his award at Siggraph 2006, July 30–August 3, at the Boston Convention and Exhibition Center in Boston, MA.

Sederberg introduced FFD as an effective tool for modeling and animation. FFD became an essential technique in every major geometric model system, animation package, and production company. Other aspects of his work revealed surprising and important insights into the fundamental mathematics of the surfaces used in computer graphics. In papers published in 1984 and 1985, he introduced the idea of piecewise algebraic curves and surfaces, which led him and others to develop elegant techniques for representing surfaces using low-degree patches.

Sederberg has written extensively on a variety of other topics for the ACM SIGGRAPH Computer Graphics Annual Conference Series, such as cartoon animation and a new geometric modeling tool called T-Splines. He received his Ph.D. in mechanical engineering at Purdue University, and B.S. and M.S. degrees in civil engineering from BYU.
