Lance Williams
From Wikipedia, the free encyclopedia
For the author of the book Game of Shadows, see Lance Williams and Mark Fainaru-Wada.
Lance Williams is a prominent graphics researcher who made major contributions to texture map prefiltering, shadow rendering algorithms, facial animation, and antialiasing techniques. Williams was one of the first people to recognize the potential of computer graphics to transform film and video making.

[edit] Education
Williams holds a double major in English and Asian Studies with honors from the University of Kansas. He was drawn to the University of Utah by a "Humanistic Computation" summer seminar. He joined the graduate Computer Science program at the University of Utah in 1972. At this time in the early 70s, the University of Utah was the hub for much of the pioneering work in computer graphics. Lance left Utah (without completing his degree) in 1974 to join the New York Institute of Technology (NYIT). While at NYIT, Williams invented the mipmapping technique for texture filtering, which is ubiquitously used today by graphics hardware for PCs and video games. Lance was later awarded his doctorate from Utah based on a rule allowing someone who published three seminal papers in his field to bind them together as his thesis. The three papers are Casting Shadows on Curved Surfaces (1978), Pyramidal Parametrics (1983) and View Interpolation for Image Synthesis (1993).
[edit] Professional career
After NYIT Williams joined the Advanced Technology Group at Apple in 1987. He collaborated with Eric Chen to pioneer early image based rendering work, developed "Virtual Integral Holography," (with Dan Venolia), created 3D paint systems and contributed to QuickTime VR™. He also has pioneered work in motion capture facial animation systems for over 20 years. In 1997, Williams joined Dreamworks SKG. In 2002 he became Chief Scientist at Walt Disney Feature Animation Studios.

1971 - Five State International Chess Championship
On August 15, 2001, Williams won the ACM SIGGRAPH Coons Award for Outstanding Creative Contributions to computer graphics.
On March 2, 2002, Williams was awarded a 2001 Technical Achievement Award by the Academy of Motion Picture Arts and Sciences for "his pioneering influence in the field of computer-generated animation and effects for motion pictures."
