A lot of FXPAL’s research involves interactive multimedia that is easy to demo but remarkably hard to capture in print. Many of us have struggled to make a simple demo clear in the flat, static pages of a conventional research paper. It was exciting to see Nature publish a paper last month that includes interactive 3D PDF content. The paper can be found here. Click on the images at the top of the second page to activate the 3D controls. One of the authors, Alyssa Goodman, has a web page on 3D PDF in scientific publishing. Her site includes links to videos demonstrating how to use 3D PDF.
