T1 and T2 Endoskeleton Research Thread

[DeltaDesignRus]

Do you think I could pour some silicone or something similar onto my timeless skull and send you a casting? Might work?

Of course, that would be very helpful.

 

[DeltaDesignRus]

I have come up with a new idea of what the cover for the rear port of the skull could have been. In motorcycles, there is a cover of a similar size - oil filler cap.

Sharing experiences or thoughts on how to improve the process is not arrogance, I appreciate it. And you're right, the paint application should be so minimal as not to damage the details, and the paint droplets should be very small. I will try not to paint the model entirely, but will apply the paint as dust, allowing the plastic to show through this layer of paint. This way, I will introduce minimal distortion to the size of the part and avoid spoiling the details. Another issue is that I don't have such a long-focus lens. I have a 300mm lens, but the minimum focusing distance is large. I also have macro rings and a teleconverter. I also have a 500mm mirror lens, but unfortunately, it's not suitable for this purpose, as its minimum focusing distance is approximately 4 meters. In general, I will experiment.

I remember once comparing photogrammetry taken with a telephoto lens and a standard lens, and contrary to my expectations, there was not much difference between the two.

I have a problem in that all my lenses won't allow me to take photos of small details in such a way that they occupy at least half of the frame because bringing the camera too close to the details doesn't allow for the minimum focusing distance. And some details are only 6-7mm in length, occupying only a very small part of the frame.

Moreover, I was surprised to learn later that photogrammetry can be performed even if the zoom ratio is changed during the process.
I had assumed that it could only be done at the same zoom ratio.

It's pleasing that there are almost no rounded edges on all these parts, which complicates measurements and modeling.

I tried to replicate this detail with silicone, but the platinum silicone was inhibited and did not cure around the edges of the detail where there was sculpting clay (plasticine). Moreover, when I poured the same silicone into a mold made from the same plasticine without degassing, everything was fine, but as soon as I degassed the silicone with the clay simultaneously, the silicone did not cure. I will try again. In the meantime, I made two details that aren't worth scanning; they have a simple shape, and measuring them with a micrometer and caliper was not difficult.

Exactly, I noticed that too in 2017 when I started learning Agisoft Photoscan and began doing photogrammetry from screenshots from T1.

Cool.

I'm wondering if anyone has actually tried any of the newer Revopoint high resolution scanners such as the Miraco or Mini 2 on anything 1:1 endoskeleton related?

The best option is most likely a stationary DIY scanner with a projector, two cameras, and lenses on a tripod.

 

[Too Much Garlic]

Yeah. Seems like it. I saw one on youtube that could do both really small objects as well as large object - all within the sizes of a Terminator endoskeleton - but I haven't been able to find the videos since. It's like they've been removed, as they don't show up when searching for the same phrases as before.

Still hope we can get all the greeblies on the gizmo skull temple inserts identified:

Terminator 1 Skull greeblies.

I’ve recently obtained an old cast of a “possible” Terminator 1 skull. In the kit is the temple inserts which show the outer edges in detail that’s not seen as it’s hidden behind the main curves of the skull. I’m hoping some people in here would be able to identify some of the kit parts...

looks very detailed ,did you scan this? what resolution does the scanner have and what is it's name of the scanner ?

Did a test recast of all the necessary details from the Flak gun kit, got a lot of bubbles, but nevertheless the results are interesting. The tiniest surface details from the original were copied without any problems in maximum detail.

Looking good

 

[DeltaDesignRus]

I continue identifying parts and drawing infographics. Anything highlighted in gray indicates either unidentified items or manually done.

 

[gizmo]

Looking fantastic DeltaDesignRus! Nice work. I wouldn’t know where to start with what kit may be involved in these parts. Great seeing you bringing it together.

And here's the first attempt at scanning using photogrammetry. The detail is covered with a very fine dusting of white, blue, and red gouache. The dusting is dry, meaning it hasn't even adhered to the detail and can be wiped away if accidentally touched. However, such a thin layer hardly introduces any error into the scanning process. But I consider the attempt unsuccessful, although the perspective is promising. Next time, I'll redo the coloring and photos, then it should turn out better.

 

[gizmo]

It’s definitely promising. It’s an amazing technique really. I never thought something like that was possible until you guys brought it up.

[Too Much Garlic]

Maybe the paint is too uniform. Didn't your larger pieces have darker spots dotted in, in irregular placements?

But seriously, that looks promising.

Though... are we sure the inside of the nose of the M1 is correct? Maybe we should stick to matching things to the EMP Museum casting.

Btw: found the uploader showing off the DIY 3D scanner I was talking about. Seems like a similar setup to the old David Laserscanner. Unsure whether the software is similar. It looks more DIY and with more features, if that makes sense. Apparently the scanner is called FlexScan3D, but only one video is showing it used in a way I would be able to use for scanning the endoskeleton... though, it seems to be a modified one... so would probably require a technically smart person.

But just look at these scans:

It is usually paired with a direcitonal turntable kinda deal, which I cannot use, but this one video shows it used in a different way.
