# Jim Blinn

James F. Blinn (born 1949) is an American computer scientist who first became widely known for his work as a computer graphics expert at NASA's Jet Propulsion Laboratory (JPL), particularly his work on the pre-encounter animations for the Voyager project, his work on the 1980 Carl Sagan documentary series Cosmos, and the research of the Blinn–Phong shading model.
In 2000, Blinn was elected a member of the National Academy of Engineering for contributions to the technology of educational use of computer graphics and for expository articles.
He is credited with formulating Blinn's Law, which asserts that rendering time tends to remain constant, even as computers get faster. Animators prefer to improve quality, rendering more complex scenes with more sophisticated algorithms, rather than using less time to do the same work as before.

## Biography

In 1970, he received his bachelor's degree in physics and communications science, and later a master's degree in engineering from the University of Michigan. In 1978 he received a Ph.D. in computer science from the College of Engineering at the University of Utah.
Blinn devised new methods to represent how objects and light interact in a three-dimensional virtual world, like environment mapping and bump mapping. He is well known for creating animation for three television series: Carl Sagan's Cosmos: A Personal Voyage; Project MATHEMATICS!; and the pioneering instructional graphics in The Mechanical Universe. His simulations of the Voyager spacecraft visiting Jupiter and Saturn have been seen widely.
Blinn was affiliated with the Jet Propulsion Laboratory at the California Institute of Technology until 1995. Thereafter, he joined Microsoft Research, where he was a graphics fellow until his retirement in 2009. Blinn also worked at the New York Institute of Technology.
