I have a passion for making pictures, especially moving pictures, especially those which serve to make difficult concepts a little easier.
The section on "algorithm visualization" describes the result of five years' of development of QuickTime® movies to illustrate algorithms from computational geometry. Most can be viewed with the QuickTime player; some require the QuickTime Player 7. There are links on these pages to play the movies, and to download groups of movies as a zipped file.
The section on "data visualization" describes one project in visualizing data from medical histories.
At the left: a frame from the QuickTime movie for a point-in-polygon algorithm: how to determine in which polygon a point lies.
