Gresham Lecture: Mathematics Goes To The Movies

An enormous amount of our leisure time is spent interacting with the media, watching television and movies. Much of the space on our computers (and on the Internet) is taken up with static and moving images, and images are also extremely important in fields varying from medicine to crime protection. These images are stored as numbers, and mathematics can be used to create, manipulate and change them. Characters such as Shrek are actually a collection of triangles and other mathematical objects, demonstrating the role of mathematics in the creation of movies.
