Common
Language Summary
The Visible Interactive Iguana.
This page presents our work on the 3D anatomical
structure of the head and skull of the green iguana,
Iguana iguana. These resources are
outgrowths of our more technical work and are intended to serve
as STEM educational aids for K-12 and undergraduate students, as
well as researchers. Our featured specimen is an adult green
iguana (OUVC 10677) collected legally and euthanized humanely in
Zoo
Miami and provided to us for research and
education. We scanned the head region on
the
OUµCT scanner in 2012 at a resolution of 90µm (0.090
mm). We
imported the scan data into
workstations running Avizo and digitally
extracted the bones and
soft tissues. The work on this project was done
primarily by Alexandra Spaw Johns, an undergraduate student in
Ohio
University's Honors Tutorial College as part of her 2012
Summer Research Apprenticeship in WitmerLab. Lexie segmented all
the structures in Avizo, generated the 3D PDFs in Deep
Exploration and Adobe Acrobat, and made the movies in Adobe
Premiere. She was assisted especially by Jason Bourke, as well
as other WitmerLab members. More content will be added in the
future. |

3D PDFs allow anyone with even the free Acrobat
Reader to interactively manipulate the 3D models that we
generate with powerful software like Avizo. The skull
and individual bones can be spun around, isolated, made
transparent, hidden, etc. The files can even be saved to
your local computer. We provide each 3D PDF in different resolutions and files sizes to match your
interest and the power of your computer.

NOTE: Bugs in many browsers prevent them from running
3D PDFs in a browser window, so please save it to your
system and then launch it.

3D PDF of the skull of an adult
green iguana (Iguana iguana: OUVC
10677) with each
bone as a separate colored object. The right side and
left side can each be turned on and off or made
transparent. Unpaired bones (e.g., frontal) are assigned
to the right side.
