These are the proceedings of the IEEE Visualization 2002 conference held October 30 to November 1,2002 in Boston, Massachusetts. The Visualization conference week actually covers six days, as discussed later, but the contents of this book archive the technical program which occurred the last 3 days of the conference.Visualization technologies have permeated almost all facets of human endeavors in science, engineering, medicine, and entertainment and are undeniably influencing the very quality of our lives. As the ubiquity of visualization has grown over the last few decades, so too has the scope of this conference. This year the conference provides an intellectually stimulating program spanning a diverse set of applications, a rich set of data and information representations, and a variety of algorithms and systems. We see this conference as fulfilling the important mission of providing a forum to promote interaction among researchers, developers, and users of various visualization technologies and applications. This annual Visualization conference series is sponsored by the IEEE Computer Society's Technical Committee on Visualization and Graphics in cooperation with ACM SIGGRAPH. We hope that you will find this year's program tightly packed with xciting papers, educational case studies, and thought-provoking panels between the visionary keynote and the capstone sessions.
