Scannology ~ Say What?

 

Scannology ~ playing with your scanner in a whole new way…

Crocheted for Lexi in 2011

On day three of my MART 186 Scanning Techniques class at SFCC we learned about scanning 3D objects. In the past, I have had lots of experience scanning items… but, I still learned things, from LeAnne Summers, I did not know. One of them was playing around with moving an item while it was being scanned! I started with this crocheted skull’s head I made for Lexi back in 2011. She and Damian were both in their skull phase As you can see this project (a scarf) was never finished… it is still in pieces. Oh well! If it wasn’t I’m sure I would not have had the opportunity to play with it now (Lexi surely would have left the scarf somewhere…sorry babe :o)

img002For my first attempt,

I placed the skull’s head sideways at the top of the scanner’s bed and slowly pulled the skull’s head down the scanning bed as it was being scanned. On the right side of this image you will see how the scanned image was stretched out as I very slowly (about as fast as the scan head was moving) moved the skull’s head in the same direction. Now I am wondering why I didn’t think to move it the other way (up toward the top) to see what would happen with the image. On the left side of this image you can see where I moved the skull’s head faster than the scan head was scanning and parts of the skull’s head were not scanned.

img004Next,

I tried the same moving technique again but this time… I let a bit of the skull’s head be scanned and then moved it and the same part was again scanned. I did this seven times apparently.  For these scans I had the skull’s head directly on the scanning bed and used my hand to move the skull’s head. You can see I scanned my hand 😦

img005Then,

I decided to see if I could make the teeth on the skull’s head grow. Again I placed the skull’s head at the top of the scanning bed. I waited until most of it had been scanned and then I moved the skull’s head down so the top of the teeth were even with the scan head. Can you tell how many times I moved it? At least six or more. The later moves (toward the bottom of the picture) I moved about the same speed as the scanners head, so it kept scanning the same part of the teeth over and over again. Too bad the teeth were not straighter… I almost accomplished what I wanted.

Ok, that was fun!

img009Now lets see…

what moving it around in circles while scanning will do? Here, I left the skull’s head in the center of the scanning bed and moved it to the left as the scanning head passed by. Oops! my dang hand was captured again. To avoid this I placed the skull’s head on a sheet of plastic. This allowed me to move the skull’s head without capturing my hand, but created a new problem. In the scans below when I had to lift the plastic (just a bit to get it up off the glass and over the lip of the scanner around the bed) it was just enough to create a hazy effect and in some places a rainbow effect due to the reflection of the plastic.

While scanning the two images below I moved the skull’s head down the scanning bed as I rotated it in a circle.
