  • The Works
  • Dr. David Evans founded the Computer Science Department at the University of Utah in 1968. It was started in part by Bob Taylor's ARPA funding a $5 million grant.

    The number one problem of the day (according to Ed Catmull at least) was hidden surfaces. Many continually evolving algorithms, such as Watkins' algorithm (which subdivided the picture), were never actually implemented but served as inspiration for more practical solutions such as Catmull's more expensive techniques that actually subdivided surfaces. (This work was presented in his thesis work "Characteristics of 10 hidden surface Algorithms" in 1974.) At the time, Ivan Sutherland did not like Catmull's "brute-force" approach, but the advent of much cheaper memory and storage made it extremely effective and increasingly practical. Indeed, it is just such a technique that is used as the basis for most all CG systems today. Catmull, as part of his interest in solving curved surface problems, had briefly attempted techniques of bending polygons before making his discovering of how to very efficiently and quickly subdivide cubic patches.

  • Other important individuals at Utah over the years included Frank Crow, Fred Parke, Jim Blinn, Jim Clark, Lance Williams, Garland Stern, Ron Resch, Alan Kay, John Warnock, Patrick Baudelaire, Jim Kajiya, Christy Barton, Gary Watkins, and many others.

  • so many pioneers!
