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. Provided by Wikipedia
