Assignment 10 - 3D Input

This assignment was totally gnarly.. I took this bitchin' little doll and stuck it to the bed of the modela with sticky modeling clay. After attaching the 3D input piezo tip, I let it run on the "fine" setting to get a 3D mesh of the little helgie. I'll let the pictures introduce you to the atrocities committed.

Here he is, with his little friends Close up of the replicas.. I was thinking about making them nest, like grotesque russian dolls

From the Dr. Picza program I was able to output an .stl file and take it over to the 3D printer. At first I thought that it would end up printing a thin "shell" full of support material unless I intervened, but due to the way that the slices/roads are handled, it ended up printing solid figurines.

The reason I didn't get a shell is that when the slices were being created, they look just like the slices that would have resulted from a fully closed model. The roads end up filling them in.

These 3D models of our heads were stitched together from 4 seperate scans, taken at 90 degree increments. We used the GeoMagic Raindrop software to make the scans (Minolta acquire feature), then the "Manual Registration" feature to put the pieces together.

You'll notice that we have a funny-looking thing over our heads. It turns out that the Minolta scanner isn't good at capturing the geometry of dark-colored objects. Our hair wasn't bright enough for it, and thus would have left big holes in the mesh. So I took a pair of regular women's nylons, put the waist part of them over my head, pulled the top together with a zip-tie, and cut the legs off. This ended up working pretty well, as you can see in the photos. We left the makeshift cap in the room afterwards in case anyone else wants to use it.
