Curvature-Based Transfer Functions: Methods and Applications

This is a web version of the talk that I gave at the IEEE Visualization conference, October 24 2003. I planned out what I wanted to say nearly word for word; these pages document those words. That means that you'll have to figure out to what I'm referring when I say "here" or "this", good luck!

These pages were made with talkweb, a stand-alone program released with teem, version 1.7 or later. The exact command was: 

talkweb -i preindex.html -t preslide.html -s outline.txt
executed in this directory. The PNG images of the slides were made either by PowerPoint or by Grab (an OS X app).
