Well, I wouldn't classify it as an imaging microscope. However, given that it's capable of allowing users to view and take very minute measurements, I think I'll categorise it as a profiling microscope. I guess that still makes it a microscope 😁🤷🏾‍♂️🤷🏾‍♂️

Micro thigmoscope

Hey, at 3:05, I'd recommend you edit that part out, putting out your fingerprint like that might not be safe. Edit: Yeah, we don't know who it's from or which finger it might be, so it can still be safe. Just wanted to let you know though.

Well microscopes touch objects with light or electrons so why not?

I'll bet you there's some nice patents on the gel.

Either the video codec has an echo or the gel does have some memory.

You can see on the lego that it has some issues with cornering. Around the base of the lego nubs it has some issues. Stuff like that may get worked out though in the future.

@@PS-bc5qt I think that tracks with what the guy was saying about the limitations - it won't perfectly show sharp angles but for the application it's not a huge issue as you're not looking at that directly

My guess is nanoparticles, and the size of the nanoparticles determines the resolution.

Right? I wonder what various kinds of feathers would look like - flight feathers vs down, etc

Height maps contain less information than normal maps. Each pixel's color channel in a normal map contains information on the normal (orientation) of the surface, whereas a height map only contains direct vertical information.

@@BiffGheek Paradoxically heightmaps can be said to have "more" information - you cannot recover height from normal, but you can generate normals from height - a 90 degree drop would not appear in a normal map.

@@BiffGheek It's possible to obtain the normal vector from a heightmap. It was a common trick in computer graphics to use the depth buffer for things like ambient occlusion, an algorithm which needed normal vectors but didn't need to be 100% accurate.

​@@0xD1CEall I know about Ambient Occlusion is how it lags my computer more thany other graphics setting

That's a really good point. My experience with regular microscopes is that the focus is touchy and the depth of field is very shallow, unlike here where the whole object is in focus.

The color are wack ....BUT the 3d efect are amazing

This is _somewhat_ doable. I make a basic version of it in my tutorial series on convolution in Unreal Engine. The tutorials are quite dry but the example project is free to download. It's not very straight forward to use as a tool though.

this is how normal maps are created, the RGB values on a normal map correspond to "lighting" the object from 3 different direction (on top, sideways, and from the bottom)

I wonder if they could make one that's 4x4m in size 🤔

@@Noclip420 The point of a microscope dissappears slowly xD

i got the same idea... so i think that could really do a thing or two

Yes! Inagine having super accurate normal maps in games. It would look amazing.

You can make normal maps of objects by taking 4 pictures with light from up, down, left and right and then composing them manually. Like this thing but of course without the whole "immune to transparency/reflection" thing. The composing would be inverting right and blending with left 50%, put in red channel, invert down and blend with up 50% and put in green. For blue, Nvidia's old normal map plugin for Photoshop could get close with its "normalize" feature from the red and green channel.

I know. The moment I saw that coin being lit from different sides, I immediately knew it was compiling a normalmap. I'd love this ability too, especially because I like making normalmaps of coins.

it instantly reminded me of normal maps as well xD

there's already plenty of software now that can use multiple images to "scan" and object and make a 3d model of it. i'd be surprised if there wasn't similar software that makes normal maps as well

what

Could you elaborate on why you think this microscope could be helpful to 3D artists?

@@Spudcosmiccc maybe creating normal or roughness materials? its a bit too small though I think

Considering the human brain's ability to extract a sense of 3D from watching 2D movies, it might explain the abysmal failure of of 3D movies and TV sets every time there's been a push in that direction. If this can help 3D movies improve on a human's innate ability (and be anything more than a gimmick) I'm all for it.

This concludes my night, I've learnt enough. Thank you for that nugget of information.

I'm here to learn where you learned this

Space filling curves

I learned what that word meant in the context of writing systems.

Not at all! We're curious beings and seeing new innovations inspires our mindset!

Uh, no, I clearly see a crater

I agree. I think I've seen something like this before that actually flips between being a depression and a bulge, but in this specific photo, it's both a bulge for me. I can't make my brain think that it's a crater.

@@hamuelagulto796 same

Maybe it's because you already saw it as a mountain first?

Same here.

I feel it shoud soun like a ruber balloon crackling while it deflates beside an object

Being animals, some noises are built into the experience.

You beat me, I am also expect an AFM.

yes exactly!

I also thought it was AFM.

I was thinking STM, but AFM makes more sense.

Yeah same here. Well played on his part.

I think it is the 80% of that technology.

I bet the gell have "working life time" ..... The gell Will be the thing Will replace regulary ..... 🤔🤔🤔

@@memesfromdeepspace1075 He actually did say that in the video, on the part with the stickiness. He said that it becomes sticky and needs replacing :)

Just tape a gel cube to the sensor and drive into things!

Would training an algorithm be easier using this technique as a source of truth? Small images, and maybe large images later, could be developed accurately with this, but would that information from this technique help you train a model faster? And further, would information about small things like the quarter or matchhead be useful for larger scale applications of LIDAR such as autonomous vehicles?

Mirrors look really interesting in a 3D picture. They're kind of like a hole.

I otoh saw the concave text immediately (after rotation), yet can't see the crater at all. It's always a mountain | plateau for me.

Same for me.

same

I had to work hard to see it as a crater, including switching to only one eye or looking away for a while. Even then, it would pop back up to mountain pretty quickly. I think it's because I saw it as mountain before rotation.

Yeah- I was able to resolve the crater in the second position and not the first, but even after resolving a crater, it was still more natural to see a mountain in both. And that's ignoring that my brain thought it was something small in the gel at the first glance.

I was just thinking about that! I believe it would be amazing for understanding markings, but, if the resolution is enough, even some features of the fabrics of materials

So much easier to look for tooling marks and scratches to see how things were made

I'm doubtful about the willingness of the archaeologists to press the artifacts into a gel. Things could easily break from the force.

@@MikkelHojbak well I can imagine a lot of situation in which force it's not a problem. There are some artifacts, like terra sigillata (I don't remember now the english name, sorry) which may not suffer. Or stoneware

@@MikkelHojbak I was mainly thinking about markings on rustued metal, but on the other hand if you take (for example) a coin, you just scan both sides and you don't have to handle the coin nearly as much, which would make it far less likely to crumble.

wait I thought there was a camera on the inside looking at the back of the pad.?

@@wishywashy1153 There is a camera behind it. They're saying that it's amazing that you can squish something into this gel and see such incredible detail on the other side.

@@unwaveringflame2482 Thanks but you just restated what I and he said.

@@wishywashy1153 You didn’t state anything, you asked a question to which “Unwavering Flame” gave you an answer.

This is nowhere, anywhere, even remotely close to having the resolution to see atoms.

@@JustOneAsbesto I was not suggesting that it did, thanks though.

‘A Boy and His Micron’ maybe?

@@nickcoleman2765 yo thats perfect!

@@JustOneAsbesto I mean isn't technically everything that it sees made of atoms?

Same

I think it's because the perimeter of the crater is all lit

Also if the subject's too fragile, the scope itself might impact and disrupt it. This'd be useless for microscopic stuff

But how reliable and accurate are they? Probably not good enough for the purposes these camera gel deforming sensing things are bought for?

Same,

Me too

I would sit on it

Funni

lol, same!😁

It's kind of the same for me. Except I see it as indented for a few seconds and then it starts to look like it's sticking out again.

to what end? wear inspection?

No money in keeping it from the public.

Why is literally no one else talking about this !?😂

Tes5icle

Imagine if objects scanned this way were used as bump maps in games. It would look amazing.

After it is rotated, the light is actually coming from the top-left. You can clearly see shadows being cast into the crater from the lip of the crater in the top-left.

@@JustOneAsbesto my brain almost always interprets it as an extrusion, even when skipping straight to the crater image, except only once I managed to see it as a crater. I have much better luck with the preview thumbnail though.

In the intro he shows a picture of the company 'The Sempre Group' and their website. The device is there, no price listed but "contact us" so probably very expensive.

@@JeffBilkins that’s silly, it doesn’t look that hard to make

@@tigergold5990 It depend... What's the resolution of the camera ? What's the focal point of the camera ? What's the material of the pad ? How many time did the software got developped ? Without thoses anwsers, you cannot estimate the price. It's like saying that VR headset do not look so expensive... Yeah but it's a small 2k screen, a very narrow focal point, and a very difficulte to make tracking device. I'm pretty sure that given the software and the regular change of the pad, it's not sold but got offer at a service.

@@tigergold5990 Probably isn't expensive to make but they will want to recoup all their research and software development.

TigerGold59, I definitely think you should make one! Maybe sell it at a lower price then this one.

**yes** thank you.

yup, that's pretty much how normal maps are generated, at least in the traditional sense of how we assign the RGB values in a normal map

Where do 3D modelers usually ger their textures from? is there like a marketplace for texture maps?

@@alejandroespinosa9030 There are many, including some free ones, and people can also create their own textures (from photos or images created in drawing apps and stuff, and other sources of images). And in recent times, there's even AI apps you can use to generate textures. And with many 3D apps you can also create textures procedurally and then bake the result into image files. And if you're talking about stuff used on characters and other complex models, those textures with a bunch of disjointed patches or that look like the character was skinned and turned into a rug, in many cases you get the images via one or more of the methods above, and manually place them on the models, either by polygon (which can be done manually or automatically, with varying levels of success, and so it's often automatic with manual touch-ups) or drawing on the models, and then in the 3D app you bake that combination into a final image (or more than one image) that has the different parts of the model mapped to specific parts of the image(s) with the combined textures.

Yes - it's a cross view stereo 3d image (video). Works very well. Not an octopus though.

I managed it with crossed eyes. Very cool 🤩

The reason why it was reversed for you was because you crossed your eyes the wrong way, outward, rather than inward, which is very difficult to do, impressive! Go the other way and it'll be normal though

@@coreblaster6809 that's exactly what he said. You can either cross your eyes (inward) or diverge them (outward). But it's more difficult for him to cross them.

For me crossing its always easier, so it's very nice.

Yeah, *somebody* has a bead-chain fixation!

NeRFs arent *accurate,* they're what I would call "true." They can guess at the shape and make it *look* right, but due to the nature of the input they're not going to be useful for any precise measurement.

That was a very interesting video. For those who haven't see it: ukposts.info/have/v-deo/kYhmdaWYjqig2I0.html

Not at this scale and level of accuracy (yet)

@@testhandle1537 Yea definitely not. But its cool to see that we're making advancements in that direction.
