3D Scanner

XX replace by something taken in the space !

Work in progress

We have a 3D scanner based on a Microsoft XBox Kinekt device, the [Skanect] software and a Mac Mini.

Instructions for use

• Log in as Guest
• Start the Scanect Software
• Configure for a BOX scan (1x1 is about righ).
• Go through each of the steps.
• Save the resulting file (PLY) to a USB disk

Reinstall from 'zero'

If the machine ever needs to be re-installed -- then know that using the cmd-alt-R recovery method will bring it back to a rather old version of OSX (Mountain Lion). Which is too old for a `decent' version of Skanect.

So you will have to upgrade to High Sierra (the max for this class of hardware).

To upgrade it from that point - you have three options - none overly attractive:

1. Find someone who has a AppStore account that is that old - and which has gone through all these OS upgrades in the past. That person will have the required installs in his or her `Purchased' set. Note that you cannot go straight to High Sierra- you need one stepping stones (such as El Captain) as you are just outside the '8 year' jump range.
2. Follow the instructions on https://www.macworld.co.uk/how-to/mac-software/download-old-os-x-3629363/
3. Make a USB bootable USB disk. Either by following apples instructions or using http://dosdude1.com/highsierra/. The USB stick needs to be 8Gbyte or bigger.

In all cases - if you get a 'OS X could not be installed on your computer. No packages were eligible for install' erorr - then, in that same, screen, select the Terminal option under tools/utilities - and set the date to some date in 2015 using the `date(1)' command.

Once the install is done - force the time to be correct (the startup may be very slow if you leave the network connected) -- as it will otherwise hang/timeout/bomb on all SSL requests.

Older versions of OSX can given you the wrong `NTP time server setting' - so if that seems to be the case - use `nl.pool.ntp.org' in the System Preferences -> Date and Time -> Automatic.

Once this is done - the following configs were done:

1. No cloud/etc accounts, disable metrics/error report sending.
2. Enable guest, and login without password into guest.
3. Enable screen lock for admin and auto log out after 5 hours so admin cannot hog the screen by accident.
4. All updates automatic
5. Enable wake up at 2 am at least once a week to enforce update fetching.
6. Auto off after 1 hour (skanekt runs can be slow)
7. Install skanect
8. Enable SSH and VNC
9. Install Xcode 10.3 (last version for High Sierra), macports and then inkscape

y creating an admin and guest account, making all updates automatic, install skanect and/or RTAB-Map according to instructions. And that is it. No drivers needed.
