Tele:
X direction: 4" - 18"
Y: 3" - 14"
Z: 1" - 27"
*I don't understand the minimum ranges, since it clearly scans the wrinkle depths which are
much smaller than 1", and it would still scan an object with an X and Y less than 3.7" and 2.7"
Middle:
X: 6.5" - 32"
Y: 5" - 24"
Z: 2" - 43"
Wide:
X: 12" - 59"
Y: 9" - 44"
Z: 3" - 69"
The maximum ranges don't make sense either, since it wouldn't scan when I put it far
enough away to get the entire 35" tall E.T.
X: 9.2"
Y: 6.3"
Z: 3.5"
X: 10.3"
Y: 12.6"
Z: 9.7"
X: 48" (not all shown)
Y: 23"
Z: 34"
Tele lens
4' from E.T. (1204mm)
Middle Lens
4' away (1216mm)
Wide Lens
4' away (1478mm (4'10") according to scanner, but close to 4' in real life)
Tele lens
4' away, mesh shown in Rapidform
Middle Lens
4' away, mesh shown in Rapidform
Wide Lens
4' away, mesh shown in Rapidform
Tele Lens
5.8' from E.T.
Middle Lens
5.8' away
Wide Lens
5.8' away
Wouldn't scan - kept saying the laser barrier was closed
Tried 30" away and got this:
Tele Lens
5.8' away
Middle Lens
5.8' away
Tele and Wide lens
~12" from E.T.
Could not scan.
Error message, "Laser barrier may be closed".
Because camera and scanner were looking at two different images?
Changing the Lenses
Turn this thing
counter-clockwise until it unhooks
from this part
Keep one hand under the lens just in case something goes horribly wrong and the lens tries committing suicide
Unscrew the ridged wheel for a long time
Keep unscrewing
Gently pull after much unscrewing
Unscrew some more
Gently pull the lens out
Place the 2 caps back on the lens
Place lens in protective foam
When putting the lens in, match this red dot to the red dot on the side
Then a third red dot should match up to these, letting you know you've screwed it in properly
1. Plug the Vivid 9i into the laptop's USB port and a wall outlet
Connects to Power
Connects to USB
2. Turn the scanner on
Open Polygon Editing Tool
Turn laptop on
Polygon Editing Tool (PET)
Scanning
In upper left corner, click the left scan icon
The right scan icon is for scanning with a rotating table
This window pops up
AF = Autofocus
Click Scan
Editing Scan
Black = object was too far or too close to scanner or was otherwise not scannable (too dark, too shiny)
Click Edit
Left click to make a shape around the thing you want to delete or around the thing you do not want to delete
Editing Scan
Right click to finish the shape
The circled part will change to tell you that a Left click will delete what's outside your shape, a Right click will delete what's inside the shape, or Ctrl + Right click to exit
Aligning Scan
Aligning
1. You cannot align your first scan
2. Once you have a couple scans stored, you can choose which one to use for your alignment by clicking on the prev/next arrows underneath the stored images
3. Click on a distinguishable part of the object from one scan, then the same part on the other scan
4. Maximum of 3 points for alignment per edit (click edit to delete something, or switch to another image to align to, and you'll get another 3 points)
5. If it won't let you make a point, try changing to monochrome view or another view. Or it might not recognize you're on a part that was scanned - not enough mesh there or something. Just click around that spot until it recognizes enough mesh.
Color Read
Replace original texture
Notice how the completed scan in the right window is messed up? This is what happened:
I scanned E.T. while holding him in the position you see in the left window. Then I placed him back down, as you see him in the right window. Then I wanted to see what "Color Read" meant, so I clicked it. The texture of the first scan I took of E.T. tilted upwards was then replaced with the image of E.T. standing normally (in other words, what the camera was looking at when I clicked "Color Read". I could have put black and white striped fabric in front of the camera and made E.T. into a zebra! Well.....sort of.)
Helpful Hints
Align first, then edit. It allows you to see what you're editing more easily, and you might realize you want to delete more/less of the mesh depending on how it looks as a whole with the other meshes
Minimize this window to look at all the scans you have, and see which parts you need to scan again
You can only move your scans in the upper right window, which I maximized:
(After aligning, but before editing out my hand)

Saving Scans
After editing and aligning, click Store
Scanning again without storing will delete that last scan
Don't click "OK" until you have all the scans you want - when you click OK, it saves all the scans as a .cdk bundle that's easy to import to Rapidform and is much faster than saving individual scans, and doing it together let's you check that you're not missing anything from your object
Wait until you're finished getting all your scans!
