3D scanning
Inspiration  I heard an inspiring talk about how 3D scanning tools are changing the way archeologists work. I decided to preserve this toy bone that a prehistoric stuffed dog buried in our lab ages ago

Who says computers are bad DJs? The GeoMagic software controlled this turntable to scan different sides of the bone


This ERROR screen caused me to lose my work and start over again. If you look at the screen, you can see inside of a partially closed bone. Using a process called "manual registration," I was lining up the 8 scans I took of the bone at different orientations and combining the images to make the object look like one closed bone. Once the scans were oriented in the right direction, I created a "shell" around them to give the image of a bone shown in other screen shots.


In an ideal world, the bone would be a light tan color all around it, however, here you can still see some of the dark pixels I had to remove (that were remnants of the parts of the turntable that were scanned with each bone scan)


Once you have a 3D model of your object, you can tweak it in many different ways. I played with the bone's length, width, and color. This image shows how I gave the virtual bone the texture of a milkbone doggie snack. I chose not to print this version to decrease the chances that a Media Lab dog would attempt to swallow my project. "Neil - where's your project Amon?? Me - a dog ate it!"

*no animals were harmed while making this project (unless you count graduate students)

Process notes/tips -I recommend starting with a very symmetrical object (that's not full of holes or  fur)

-8 scans (4 of the top, 4 of the bottom) of an object is more than enough to piece together a 3D image (in my opinion)
