Hey Dale! Thank you so much for the comment! I'm glad that my video provided some extra info for your decision :) Great questions, let's answer them: 1. The ability to scan a fuel tank for reverse engineering: The answer is yes! However, to make an accurate scan with the KIRI Engine, you need to prepare the tank before photo-scanning it. You can buy a scanner spray that can make the surface less reflective, then use some baby power (or chalk power or anything that you can put on the top to increase feature points). Once you've done that preparation, you are ready to make super accurate 3D scans with just your Pixel 7. 2. Measurement: Although the relativity is all there, there is no real-world scale straight out of photo scanning. But it's not an issue, you can manually scale the model to real-world size in other 3D software such as Fusion360, here is a video on KZfaq that teaches you how to scale a photo-scanned model: kzfaq.info/get/bejne/l96Ug6yUm6zVgYk.htmlsi=Mx1LyUH_J_ELMgH_&t=316 3. Pricing: Unfortunately, KIRI Engine doesn't have one-off purchase plan. The reason for that is KIRI Engine uses servers on the cloud for processing 3D scans, it's financially not feasible to just charge once but the server cost is being accumulated. However, having said that. I'm almost certain that you can achieve accurate 3D scanning of your bike's fuel tank without having to become a paid user, our free features should be sufficient for your need. Just remember to prepare the object before going for a photo scanning; If you did need a paid plan, although it doesn't have a one-off purchase option, you can actually become a subbed user for a month for only 15USD, then cancel it whenever you finished the project, this way it's much cheaper and efficient than buying a physical 3D scanner :) Let me know if you have any other questions, happy to answer more :)

Hey~ Yes, you can :) In KIRI Engine, you can actually export the 3D model in STL format, which is perfect for 3D printing! But I do wanna point out that when scanning a person, because the person would be moving slightly, KIRI Engine can be hard to use to scan not-stationary objects. But feel free to try it out :)

Hi Ryan! Thank you so much for the comment! The feature of creating walls and furnitures are called RoomScan, this feature is available on both KIRI Engine and Polycam. On KIRI Engine, RoomScan is completely free :)

Hey MasterThief!! Thank you so much for the kind words :) Haha, yeah LiDAR scan in KIRI Engine is gorgeous. But in terms of the final 3D scan result, sometimes photogrammetry will produce better mesh details :) So don't be too frustrated even if the iPad Pro isn't around. Hey, feel free to try it out and let me know how it goes :)

Hey Adrian!! Thank you so much for the comment! First of all, nice car!!! I can clearly guess why you'd need a 3D scanner like Kinect (I was super into cars, too :D). Believe it or not, Kinect was also my first 3D scanner and I hated it so much lol. That's exactly why I wanted to make KIRI Engine because back then, the only affordable option was this useless sensor from my Xbox :( So I wanted to make 3D scanning affordable and accessible to more people like me. Feel free to let me know if you got any questions or concerns when trying out KIRI Engine and other 3D scanner apps :)

Hey Zaviekucer! Thanks for the comment, I actually found a pretty good video on how to use a 3D scan model on Solidworks here: kzfaq.info/get/bejne/mqpdqq91t6m8Znk.htmlsi=vPWtbRBCCCNcrbJh

Hey Antonio! Thanks for the comment. To make sure our company can grow and delivery better products over time, we really need a business model to support the team financially. But in this video, all that I've shown in KIRI Engine are the FREE features, if I were to compare the paid features in KIRI with Revopoint, oh man, we can do so much more :)

Woah iron bro! glad you discovered this video :)

Hey Namaste!! Thank you so much for the comment, please don't hesitate to let me know how it turns out :)

​@@jackisbuildingkiri2997 I already, tested your app, the result was quite good, and I also the photogrammetry. One thing which I encountered with the Scan from your app was it distorted the x axis scale, it was starched. But it was first attempt, although i tried to stay suddle with my moments. I used the same images to make the photogrammetry scan and as i have already worked with it in past, so it came out perfectly. To test the scaling (how distorted it was with your apps scan) I aligned both scans in blender, and designed parts according it it and 3d printed and tested. But I will scan once again with your app for another test, with some diy scale and marking points. And video will be uploaded soon.

Hey Alex! Thank you for the comment, and I sincerely apologize if my video made you uncomfortable :( We designed the KIRI Engine with a different approach. We realize that no matter if a user would use an app or hardcore software for 3D scanning, if they are a serious users they need the 3D model to be in high-quality for the actual 3D pipeline, that's why despite KIRI Engine has a longer processing time, it is meant for the final result to be completely usable for 3D creation. And after all, the free version of KIRI Engine has more features, and the paid version is way cheaper, so why not try it out :)

Thanks mate :) Feel free to let me know if you run into any questions or concerns

Hey DragonballToys, thanks for the question! 3D scan result-wise, both devices have equally good results. But KIRI Engine on iPhone does have a better user experience than it is on iPad because we primarily designed KIRI Engine for phone, not for tablet

Wait what? I'm so sorry to hear that, this doesn't normally happen haha. Which scan mode did you use? Was it object capture from LiDAR Scan?

It's kind of hard to scan a clean car body because of its shiny surfaces. But if you are looking at the mounting locations, I assume it's either a kind of dirty/rusting car or parts of a car? If so, KIRI Engine is up for the challenge. And yes, you can apply the measurement to the set point in software like fusion 360 afterward. And also, since you have an iPhone with LiDAR, also try our Object Capture under LiDAR Scan option, it will get you some clean results too :)

​@@jackisbuildingkiri2997the mounting locations could be made dirty or perhaps sprayed with a matt paint that can be washed off. What about detail? If I scan a whole vehicle can I then move in closer and closer to the mounting points to get good detail in those areas? Sometimes they will be holes, sometimes channels with outer lipped edges etc. How mm perfect could these areas be scanned? Does Kiri deal with holes and pockets well?

@@sharpsticksnz4112 Hi! Thanks for the reply! If you can actually make the part dirty or put on matt spray to create more feature points, then you can get really accurate models that you wouldn't tell differences between KIRI app and the under-1000-dollar 3D scanners. And yes, if you can make enough feature points, you can take close-up photos to capture more details. Feel free to try out KIRI Engine app, it's free after all :)

Hi there! Thanks for the comment :) Yes, the reason you couldn't get a good model of the train is because they are reflective. I'd recommend putting some white powder on their surfaces to create more feature points, or you can also try our Featureless Object Scan, which is designed to scan featureless objects with the help of AI. Feel free to let me know how it goes by replying here :)

Oh yes absolutely! Actually, I find KIRI Engine is really, really good at scanning clay sculpture, even with the free plan. You'll be amazed :) Feel free to let me know who it goes

Hey! Thank you for the comment, I don't want to disrupt the competition, and I'm only speaking from a 3D industry expert perspective of view. If you want your kids to learn 3D and to find a fun companion for their 3D printed toys, I think qlone can be a great choice because of its price and intuitive user interface, and in fact I think they are doing really great in education markets. But if you are looking for a productive tool to help improve your 3D workflow, I find qlone isn't really designed for that

@@jackisbuildingkiri2997 how much does Kiri engine charge?

Heyyy Slabua :) Thanks for comment, I knew someone would bring this up :) I think because KIRI Engine uses any smartphone, it really doesn't count as an extra cost

Good question :) The answer is yes! As long as you can take photos around it, we can 3D model it! It can be drone footage shooting around a mountain or even a video shot from space to orbit around the Earth! (theoretically, because I obviously haven't tried lol)

Great question! On the uploading page in KIRI Engine, you will have the option to make your 3D model visible or invisible to others. If this is something you want to keep it with yourself, you can just turn off the visibility button :)

@@jackisbuildingkiri2997 Love your marketing and videos. Thanks for the information so is there anything in the fine print that says you have rights to the images. I'm updating my book '3D Technology in Fine Art and Craft: Exploring 3D Printing, Scanning, Sculpting, and Milling," and reviewing things to share with the reader. Thanks,

@@WomenSteppingOutside Thanks! Actually you can find our full end-user agreements here: www.kiriengine.app/user-agreement, if you ever have any concerns or questions regarding the user agreement, please don't hesitate to let me know via my email [email protected] :)

Haha thanks! Well, I'm still replying. So I guess we not big enough :P But I'll try to reply as much as I can

I wish I knew how to say THANK YOU in Russian, but I'm gonna pretend and use Google Translate, haha. Still, THANK YOU SO MUCH!!!! It really means a lot to me

Hey! Thanks for the comment! I like Polycam too, it's one of the very first 3D scanner apps on iPhone. I actually did a comparison video the other to show my favourite 5 3D scan apps, feel free to take a look: kzfaq.info/get/bejne/b8qpdM1qzL6tnac.htmlsi=40XQoV0z0D_qfbgO

Thank youuuuu :) Feel free to let me know if you have any questions in the future

@@jackisbuildingkiri2997 first app ceo that gave an actual reply, I love how you care about this and want to send us to the future! The premium version has been a complete game changer as well as the photo and featureless object scan!

Thank you so much!!!!

Thank you so much :) Please let me know if you got any questions or concerns using KIRI

@@jackisbuildingkiri2997 do you have a specific tutorial for capturing a small product jar? I’m trying to capture all angles even the bottom.

@@LoboOutdoor Unfortunately, I don't that specific tutorial video :( Scanning the transparent and reflective jar can be pretty challenging especially if you also want the bottom of it. You will definitely need the Featureless Object Scan in KIRI Engine, but if you just put on a surface, you won't be able to capture the bottom because unlike Photo Scan mode, for Featureless Object Scan you can't just flip the object during the scanning. So I would say, if you really want the jar with bottom included, you can try to hang the jar in the air so this way you can shoot a continuous video all around the jar including the bottom without moving it in the Featureless Object Scan mode. I hope it helps, feel free to send me an email at [email protected] if you are having more questions about the process :)

Hi there! Just search KIRI Engine on your app store or play store :)

Woah nice! Thank you so much for sharing this with us :)

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.

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

Woah, that sounds like an interesting project! Honestly, I don't know. But feel free to try it out :)

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

Thanks for the question, and no. NeRF is still there in KIRI Engine. But we don't call it NeRF because this technology has involved into something beyond NeRF :) The NeRF in KIRI Engine is called Featureless Object Scan. And instead of just 3D reconstructing a radiance field that is barely usable in other 3D software, we used a new approach called Neural Surface Reconstruction, which inherits the best parts of NeRF, the capability to 3D scan shiny and transparent objects (aka Featureless Object), and on the top it can even generate good mesh!

@@jackisbuildingkiri2997 Thank you very much for the comprehensive response. If I understand correctly the "nerf tech" works with any ios or android phone and it's camera and does not require any special chipset/hardware? Only for Lidar works with specific ios devices?

@@ACEPARADE Correct, NeRF works on any phone and camera, Featureless Object Scan is also available on both iPhone and Android :)

@@jackisbuildingkiri2997 thank you e-mailed you to talk further

@@jackisbuildingkiri2997 thank you, sent an e-mail to talk further

Woah, thank you so much for the subbbb!!! Feel free to let me know if you have any questions in the future :)))

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 :)

Except there are many great, free apps available that literally cost the end user nothing aside from the installation (and without giving up rights to your data). Your personal policy about free apps might be costing you.

​@@clkb8moto@clkb8moto Totally agree, there are indeed other apps that are completely free. But in the long run, I think an app would really need a business model to keep it alive, don't you think :) If they don't charge any money from end users, they probably will run out of money soon or like @darkstarprojekt said, get money from other things like throwing randoms ads to their users or selling user data :(

@@jackisbuildingkiri2997 I'm not worried about selling of data, I'm more worried about cloud based software that can see what I'm making (nothing illegal, just propriatory)

Hey, I totally understand :( I Feel sorry if this video made you uncomfortable. You know I hate running ads on social media, so I thought I could help people understand KIRI Engine in a better way. I'm putting disclaimers on all my future videos if I are to mention others' products

Do you often cut off your nose to spite your face? I'm trying to figure out how Jack was dishonest other than not stating that he is affiliated with KIRI? Did he misrepresent the others? I'm pretty sure that the video is fairly accurate. KIRI is arguably the best even if you do have to pay for it.

Really? I tried Kiri and it still hasn’t made it in my top3 scanning app yet, please enlighten me on what I am doing wrong?

@@ericchen7026 🤷‍♂️ None of them work well enough to use for detailed needs in my estimation but for creating digital assets it works as well as anything else in my estimation.

Hey Bushra, thanks for your question! It actually depends on if you can use a zoom camera to capture enough details of an object even if it's 3cm small. If you want to capture something tiny, the best chance is to use a telescope camera to capture the details of it and use the upload from local option in KIRI Engine to upload those photos

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

Don't use LIDAR. It does not increase detail in the scan.

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 :)

@@jackisbuildingkiri2997 great thanks

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 :)

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

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
