Some time ago Ordibble Plop told us that this shell comes from his homeland New Zealand:viewtopic.php?f=6&t=90&p=336&hilit=shell#p336
Now I have scanned it again using the turntable and two stepping motor driven lasers. One laser was standing above and the other below the camera. By using two lasers it wasn't necessary to change anything of the set-up because all parts of the frontside of the spherical object could be illuminated, also the shadowing sides of the pimples. So the scanning process could be solved in a very short time only by sitting in front of the PC, controlling some switches.
Two identical focussable red lasers from the DAVID Shop.
Modified Logitech Pro9000 (now Pro9001) at 960x720 pixels @ 15fps.
Diameter of the shell: 65mm.
Eight turntable positions á 45°.
Each of the eight scans was 1x interpolated but not smoothed.
The two motors were alternately driven from one controller
/ motor driver
. Only by toggling one three-way switch for the lasers and the motor coils.
Edit: Now you can see the shell as a pdf in the WIKI Multimedia Gallery. The original has big holes at the upper side and underneath. They were closed by the Poisson fusion because I had "forgotten" to scan the holes. http://www.david-laserscanner.com/wiki/ ... /shell.pdf
