[@mario_r_o_c_h_a]

Congrats for this cool review. 🙌 I am a user of many photogrammetry, LiDAR, and 3DGS software and apps. KIRI has given me the best response so far in terms of quality, it's just a bit slow in obtaining the model, but still, we're talking about minutes. The user interface design is what I like the most. Speaking of Revopoint in this comparison, it has that disadvantage, but I think intentionally using black in a scan can be creatively utilized, like a chroma key or mask to remove unwanted parts of the object. IDEA: It would be amazing if KIRI could do that with a color selector, not just black. I'm not sure how useful it could be, but if feasible, it would be cool.

[@senseisecurityschool9337]

IMHO It' absolutely appropriate for you to make this kind of video. It's wonderful that you try to be fair when comparing your products to "competitors". The ONLY issue with your other video was that you didn't disclose that Kiri is your product.

[@jackisbuildingkiri2997]

Hey man! Thanks for the question :) Yeah, I confess I was being cheeky in my previous video comparing the 3D scanning apps, that's why I added my background disclaimer in this video to avoid misunderstanding haha. And honestly, I don't really see a $600 3D scanner as our competitor because as I indicated in this video, they are really designed for different use cases :) If you are looking to get best texture quality for game design or VFX, doesn't matter how expensive a 3D scanner hardware is, photogrammetry will always win; But if you are looking to using the 3D model for measurement and reverse engineering, never use photogrammetry, buy a 3D scanner :)

[@Kaliumcyanidful]

Does your app support retroreflective reference points? Would it be feasable to implement to Track geoemtrys with low feature density? They could also be put on the surrounding geometry instead of the model 🤔

[@jackisbuildingkiri2997]

Actually, we believe we have a better solution. In this video I only talked about the free features. But we also have upgraded premium features, which have a pretty unique thing called "Featureless Object Scanning." What's cool about it is that it uses a neural network-based algorithm to generate mesh even if the object itself doesn't have feature points. I made a thorough overview video here, feel free to take a look :) kzbin.info/www/bejne/gqKVXp-Qat2kq5osi=z-lGcKM4zwWNb4iG

Aesub scanning spray. I recommend the orange. Don’t use a 3D scanner without scanning spray. 90% of my parts I had to scan needed scanning spray because of color or reflective surface. I own Einstar, Einscan-SPv2 and Revopoint mini.

[@julianandyvonne]

I enjoyed the video. It could be what I'm looking for. Will it scan things like an indicator or light on a car? If I wanted to replace it with a 'custom' light I would need to scan the hole left behind after it is removed. What about parts of a panel on a car? Keep up the good work. I love the enthusiasm 👍

[@jackisbuildingkiri2997]

Thank you so much for the question! For the car parts scan, I'd recommend the Revopoint 3D scanner over the KIRI engine due to its real-world accuracy. But keep in mind, you do need a scanning spray to paint over the car part if the part you are trying to scan is reflective or dark

Hello, I need lidar to clearly detect large buried metal structures, and I will pay any price for that depth of 4 meters.

[@davidgruty]

What android phone would you recommend to get the most out of Kiri? I understood Apple has lidar sensors and this helps a lot with the results, any options in Android?

[@jackisbuildingkiri2997]

Hey David! Thanks for the question! Like I replied in the other comment, believe it or not, Apple's LiDAR isn't necessarily helping with the results but more with the user feedback, so whatever you can get from Object Capture in KIRI Engine, you can almost always get it in greater detail with the Photo Scan in KIRI. And for Android recommendation, as far as it has a great camera, it will get the same result as from an iPhone, so any latest Android phones with good cameras should be good for your choice :)

Does it possible to scale model from KIRI by known distance/coordinates?

[@jackisbuildingkiri2997]

Hey Karol! Thanks for the question, but unfortunately KIRI Engine doesn't have in-app scaling feature yet. So you'd have to import the 3D model to other 3D software like Blender to scale it yourself :)

[@LincolnWorld]

I've been thinking about this for a while now. It seems like what you were saying in the video is that the Lidar in an Iphone helps with the user experience, but it didn't sound like you were saying that the end result is noticeably better when shot with the Iphone. Is that correct? I have an Android, and I'm thinking it's not worth getting an Iphone if the main reason is for scanning.

[@jackisbuildingkiri2997]

Hey LincolnWorld! You are absolutely correct! LiDAR has been over-hyped by many people who don't actually understand how 3D scanning works. The 3D results directly from the LiDAR sensor are almost unusable in any application. And that's why you see most of the LiDAR scan demos are for large-scale rooms or environment because such large-scale object can look pretty good even if the accuracy is low. So when talking about the Object Capture feature in KIRI Engine which utilizes LiDAR and photogrammetry, it only use LiDAR to improve user feedback and improve processing load on your phone, but whatever good result you can get from Object Capture, you can get it better from Photogrammetry

Trying out Kiri engine, and I don't see an option anywhere to make the model watertight or fill in holes, All I get is a shell with an open bottom tons of holes that I can't 3D print. Any tips for cleaning it up and making it 3D prinable?

[@jackisbuildingkiri2997]

Hey Professor! First of all, love your video :) Like I described in the video, if you get tones of holes from a 3D scan, it generally mean the object itself doesn't have enough features points. I suggest look for some objects that have enough features points for photogrammetry. It should be watertight by itself if the object is right :) Let me know if still no success

@@jackisbuildingkiri2997 I scanned a cup with a lot of features on the face of it. But because it was a cup I couldn't really get a good view inside it past the top lip. So I ended up with, essentially, a tube of useful points, with an open top and an open bottom. And besides scanning it on a sheet of clear acrylic, I'm not sure what I can do about closing up the bottom, but the top should have been closed in some way, right?

[@jackisbuildingkiri2997]

@@3dpprofessor Ah I see! If you have gotten the sides of the cup and just want to close the top and bottom, use the cropping feature in the app, you can just plane cut the top and bottom part and there's a option called "Fill Hole", turn that on wait for the server to process it, then you should get a watertight surface

I want to scan people’s faces for 3d printing. Will this work for me or should I buy the $1500 dollar scanners. And if it works, what IPhone is the best?

[@jackisbuildingkiri2997]

Hi there, thanks for the question :) That actually depends on what you want to use with your face scan. If you are looking to use the face scan for 3D printing, then yes, you'd need a 3D scanner like Revopoint or better; But if you looking to use the face scan for game development or VFX, actually KIRI Engine + Unreal's Mesh to Metahuman would be better alternative for better texture and rig control. And if you are with the latter use case, You don't have to have an iPhone, both Android and iPhone work equally the same for face scan and with the mesh you can use it in Unreal-s mesh to metahuman

[@Kaliumcyanidful]

Excellent Video! The results are amazing! but currently scanning spray should be considered standard when using consumer scanners. Also if you buy a Scanner for 600$, a few for the spray should not matter to much.

[@jackisbuildingkiri2997]

Thank you so much for the comment! And yeah honestly I didn't realize that so many people would use scanning spray because in some parts of the world it's pretty hard to get scanning sprays. But I'll make sure to make more video in the future to compare the result from scanning spray

[@SneakyJoeRu]

I always wondered why don't such apps as Kiri use ToF sensors found in phones. Pretty sure it could result in somewhat accurate dimensions. Maybe you can shed some light on that. Those sensors are used for measuring of room size, for instance. In conjunction with phone's gyroscope I believe the estimation could be done really well. I also adore Kiri for free exports and consider getting paid option when I'll be scanning a lot of things.

[@jackisbuildingkiri2997]

Hey Joe! That's a great question! The short answer is that the ToF or LiDAR sensors on our phones aren't accurate enough to be usable in 3D scanning. It's true that ToF sensors can give instant measurements of the object they're pointing at, but the accuracy is usually in the 1mm-5mm range. Imagine a 3D-scanned surface with 5mm-deep bumpiness all over it. It would be more terrible than even the cheapest 3D scanner you can find. For that reason, ToF or LiDAR data is rarely used in actual 3D scanning techniques for object reconstruction. But you'd see many use cases in which people use ToF sensors to measure rooms, right? That's also because, in a large-scale environment like a room interior, accuracy isn't that critical. You'll be okay if the measurement is 5mm off for your room, right? So that's why it's good for room, but not good for object reconstruction

Lidar object scan needs work. 3 scans just crashed in a row on my iphone.

Hey bro, are you still getting crash issue? Which system version are you at? is that 17.4 or later?

[@rescuemethod]

What is the accuracy of the scans? Plus or minus 0.1mm? 0.2mm?

[@jackisbuildingkiri2997]

Hi there! Thanks for the question! Actually, we don't use accuracy to measure the quality of photo scanning techniques, because the level of accuracy depends on the image quality and the level of features points on the object surface.

[@jackisbuildingkiri2997]

But let's put it this way. If the object has enough features points, and the image quality is good. The re-scaled 3D model can have less than 1% of accuracy loss, which is almost the same (if not better) comparing to Revopoint

[@chiboreache]

what about phones w/o lidar 🤔

[@jackisbuildingkiri2997]

The phone without LiDAR, KIRI Engine has photogrammetry. And honestly, in my opinion I think LiDAR has been over-hyped for 3D scanning, because when it comes to the texture and mesh quality, LiDAR can't compete with photogrammetry, so you still have our best tech even if the phone doesn't have LiDAR

I’ve seen it but it’s like a mini clip part of another video. It’s not clear if you have to just the move the object and lineage the camera still or you can circle around it first and then move the object and circle around again. In this video for example you do scan the statue on all sides but the with Kiri you didn’t hehe

[@jackisbuildingkiri2997]

@@Teteerck Ah I see, the reason why different videos show you different approaches is because you really can use different scanning methods. The way I personally like to use to scan objects on all sides is: 1. put the object on a place where you can easily walk around it to take photos 2. when taking photos, don't move the object, you walk around it and take the first rotation of photos 3. then flip the object to another side, and walk around it again to take the second rotation 4. Do it one more time with another side 5. On the uploading page, make sure you turn on the "Auto Object Masking" toggle, then upload the photosets

Nothing is free. I will NEVER install anything advertised as 'free'. I admire the work you put into hacking IOT and pre-existing platforms and creating the software to make these things, but I am extremely wary of sharing my work on other peoples software.

[@jackisbuildingkiri2997]

Hi there! Thank you for sharing your thought with us :) I completely understand your concern, in fact, KIRI Engine uses a business model called "Freemium" to maintain our operation. That is, we provide basic features free for everyone, but trying to convert a percentage of the users who uses the free features to use our more powerful paid features. It's called the "80-20 rule", although the majority of 80% of users can totally benefit from the free service we provide, even if there are 20% of hardcore users who need more advanced features to accomplish their work, we will generate enough revenue to help grow our company to develop better and better products. And for the record, some people would think a company can make money by selling user data, but the truth is, you really can't make a living by selling data, haha. Any legit companies don't really have the motivation to do dark businesses like one would think :)

[@Flamenawer]

Very poor comparison, technically as you didn't show the base mesh of the mini, say Lidar when it's not , Apple can say whatever they want, but that is not a Lidar, it's a dToF camera and again you didn't show the mesh. You are confusing 3d scan with 3d model or use them at convenience ,but they are not the same thing. One thing is a 3d scan, other is a 3d model. Precisely, the ones that made good visual 3d models but bad scans , you didn't show the mesh of that, if you want to compare a 3d scanner compare the 3d scans , point cloud or mesh. Scan with Kiri is not free either, the iPhone is $1400 as you need pay the data plan, we can discuss that probably you have one anyways but that is not the point. Also you took the worse scanner in that price range probably,also the scanners are sold and made for specific sizes, (some can do small to big as new Creality scanners) if you make that comparison with the Creality 3D scanners Otter and Raptor, Kiri 3D scans would look quite bad compared, as the textures of them would look quite badd compared with Kiri. Many scanners has not color even textures, it is not a important variable for them ,is geometric fidelity and precision. Other thing that you compare but it is not comparable are the textures type, as the photogrametry ones will be always better as they are pictures retro projected while the 3d scanners textures are vertex color from XYZRGB point clouds and the mesh receive colors from them and interpolate the faces colours. Again you are comparing apples with oranges there. You can still make a perfect 3D scan with reprojected textures, in example using the scanner mesh and align with the Photogrametry mesh and transfer the texture so easy as that, well no so easy but it is in your hand help with that. You are doing very nice job as CEO, you are making a great product, for sure you are nice guy, easy to note that and I think you probably made what in yours eyes is informative, representative, whatever, I would forbid that from a reviewer, but are the CEO, even if you didn't under a interested point of view, you are a interested part, so with the above makes this video look a kind of miss informative and biased. Is nice to see you in the screen and would try show to apply your app in real world use cases with scanners ,as swapping textures to improve the scans than compare them. Photogrametry can scan as good as almost any scanner but paying a price in equipment, as polarised equipment, etc maybe you can help us with that, in fact, commercially is one of the possible use cases of your app, make textures for 3D scans, I would happy to help with that . Sorry by my bad English

[@jackisbuildingkiri2997]

Hey Flameawer! Wow, thank you so much for this super detailed comment :) You made yourself very clear, and English isn't my mother tongue either. I agree, say 90%, of the the opinion stated :) Obviously you are a very very knowledgeable person in 3D scanning, but a lot of users who use KIRI Engine are not experts in such techs. For many many times, people have asked should they buy a 3D scanner or use a 3D scan app, and I totally agree with you, I'm comparing apple with orange here. But if that's what people got mostly confused about, I should at least do a comparison to show what they perform like shoulder to shoulder :) And actually, I was surprised a bit too, did you know that the Revopoint Pop 3 can also give you color textures based on topology? There is an option in the Revopoint software where you can choose to either have a color image or vertext image. I think I slightly showed it in 6:42 of the video. But still, the RGB camera in the device is pretty bad for cost optimization

Hi Cicilia! Thank you for the question! This is where I'd actually recommend Revopoint over KIRI Engine. The scanner has real-world scale and can be accurate enough for tailor clothing. Just make sure when scanning a body with the scanner, make sure the person don't move too much during the process and that the cloth they wear do not absorb too much light (definitely don't wear black cloths)
