• These interactive visualizations are in PDF format and
were generated from Adobe Acrobat 3D, which is a
relatively new program that permits the use of
interactive 3D content in the widely available and
familiar PDF format.
• To use these files, you will
need to have an updated version of Acrobat Reader, which can be
downloaded for free! It's worth the time to
download the latest Reader, not just to access the new
3D capability but also simply to have the most current
version of the Reader—it is, after at, the same Reader
used for conventional PDFs, but now with interactive 3D
• Each 3D PDF is provided in three files sizes.
Larger files provide more detail but take longer to
download and require a more powerful computer. Smaller
files are blockier but easier to manipulate.
• Clicking on the links below will launch the 3D PDF
in its own window. If you don't have the
most up-to-date Acrobat Reader or it's not set in your
web browser as the default for opening PDFs, then you
might get an error message. Check the
mini-tutorial for help troubleshooting the problem.
