Thank you so much mrfunnysheep!! Your support has been so freaking valuable to us!! Let's goooo

Hey Pavanrzx! Thank you so much for the honest feedback, and actually we are planning to lift the photo limit for free users :) Although it's not settled yet, we are going to increase the photo limit to 100 or more and unlock upload from local for all users. Right now, we are in the middle of an app UI upgrade, right after the current update is delivered, we will start making those changes. Fingers crossed!!!

@@KIRI_Engine_App I love your responses here on YT. It genuinely seems like you care about being upfront with the users of your app.

@@LincolnWorld Thank you so much, man! Really really appreciated the support. Yes, I try to create deeper connections with users :) I think this way I get to learn a little bit more about the market and the market can also learn a little bit more about us

OMG, thank you so much maticola!! Two years of support really really mean a lot to us :DDD

Thank you so much for the support!!! Let me know if you have any questions or concerns

Hey Jerome!! Thank you so so much for the comment, really appreciated your support :) Glad you said that, because we are planning to increase the photo limit in the photo scanning in the soon future. Although we haven't finally settled the new photo limit, but it will be somewhere above 500 photos for a Pro user, this limit lift will be introduced not the next major update, but the one after (because we need to do a UI update in the next one). And to the second part of your question, no, phone model and camera deosn't make a huge difference in texture quality, but we do find that iPhone cameras are essentially better than most Androids, so using an iPhone could help improve the color accuracy of the texture

Thank you so muchhhhhhhh, I'm so glad that you like what we've created haha. Please feel free to let me know if you run into any questions in the future :)

Good question xbizuk! If you use the photo scan or featureless object scan features, then no, it doesn't come with real-world measurement, you'll have to manually scale it on 3D software for accurate in-scale measurements; But if you use the LiDAR and object captures features with an iPhone Pro, then the 3D model will actually include the real-world measurement

Thank YOU for the support!! Feel free to let us know if you got any questions :)

Thank you so much!!! I love you too

Hey! Thanks for the question :) Did you try our featureless object scan option? It should be good to capture object that's black

@@KIRI_Engine_App I haven't tested it yet because this feature is only available in the paid version. I have a few more questions: 1.When removing the background from intricate parts, such as a fan's grille, a mug handle, or wires from a black object, what's the best approach? 2.Does it make a difference if I use a white, green, or another colored background? 3.If there are markings on the background, like dots, does it assist the app in the background removal process? 4.When scanning larger objects, like the size of a car, would it be better to have fixed lighting that illuminates everything or directional lighting in the area being photographed, such as a ring light with soft light connected to the camera?

@@romulotrindadealves6611 Hey, great questions, man. Let's answer them :) 1. To remove some parts from a 3D model, you'd first need to export the 3D scanned model as quad mesh for better editability (This is one of our advanced export features, so, unfortunately it's also a paid feature). And when you have the quad mesh of the 3D model, you can then do the part removal process on third-party 3D software such as Blender. But to be able to properly remove the parts from a 3D object, you'd need some 3D modeling skills to help 2. Using backdrops when making a 3D scan doesn't really help that much in today's 3D scanning. Using a white backdrop will, tho, help you get the 3D model with neater texture quality, but that's pretty much it 3. No, it won't improve the background removal. We use an AI algorithm that automatically tells the object from a background, and it's pretty smart as far as you include the whole object in the photoset, not just a part of it.

@@romulotrindadealves6611 and 4. When scanning a car, specifically speaking. Yes, an even and smooth lighting environment will absolutely help with the result. But more importantly, to get a good 3D model of a car scan, the car itself needs to have a lot of features points (I know we have featureless object scan, but frankly speaking, it doesn't do well with car scan). So, in my experience a dirty car will work better than a brand-new shiny car

Good eye, haha. Frankly speaking, although we are very very proud of our Android support, I have to admit KIRI's user experience is slightly better on iPhones :( And that's actually an important factor that made us re-design the UI to align the user experience between iPhone and Android, the new UI experience will be out in the next major update

@@KIRI_Engine_App Thanks for responding. I'm actually new to Kiri and intend to upgrade to premium but currently stuck with the Galaxy S23 (not having the budget to switch to iPhone 14 Pro, which everyone seems to recommend). So, is the quality of the scans/models better when done on iPhone or same (so up to the system/Kiri)?

​@@k16e@k16e Ah, actually, the final scans won't have much difference doesn't matter if you use an iPhone or Android phone. It's just the over all experience is a bit better on iPhone, you know, like the font size, app animations etc.

Hey Joe! That's a really good question, it's actually already there :) If you happen to use an iPhone Pro, we actually have the combined version that utilizes both LiDAR and Photogrammetry, it is called the Object Capture :) I even made a whole other video talk about this cool feature, check this out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TeIi0BsR1Qs.htmlsi=IVO0ERZcbLllyoJT

Heyyyy! Thank you so much for writing to me; this is Jack replying. As a junior software developer, I think you are up for a great start with strong self-initiative. To build an app like KIRI Engine, we divide the developer into front-end and back-end, each having their own unique skill sets. For the front end, developers focus on creating the user interface according to UI designers' designs; you can learn how to make front-end-oriented apps from many app development courses and RU-vid videos. For the back end, developers are focusing on making sure the 3D scanning algorithms work as expected. For that, you'll need to have backgrounds in computer graphics, computer vision, and a little bit of machine learning (and python as well) Hope this short reply can help you a bit in figuring out what you need to learn, feel free to let me know anytime if you have any questions :)

@@KIRI_Engine_App Holy cow! A real response in the wild! Man, I appreciate the thoughtful response. I'm lacking in the computer vision / computer graphics department, and this is plenty to get on my way! Dude, thank you for being a personable human, I am humbled by your thoughtfulness! thank you for making my week!

@@smellslikeupdog80 Haha, thank you man :) Yes, we like replying comments and emails :) Feel free to join us on our Discord server, we talk all the time with other users there: discord.gg/Jt2JHG7BAc

Heyyy! We were actually just discussing the feasibility to bring 3DGS to Quest 3! The two things that are stopping us from doing that right now are 1. To bring 3DGS to Quest natively, we need to be able to render 3DGS in Unity more efficiently, and unfortunately our team isn't really familiar with Unity development, so to do that we'll need to get a couple more people onboard. 2. Not only Quest 3, even though Apple Vision Pro is cool, unfortunately, it doesn't really provide much financial return for the team. And in order to make our team grow faster and deliver better products as a startup, we first need to focus on the projects that can potentially provide enough financial returns. So back to the question, yes Quest 3 is on our radar and we want to bring 3DGS to Quest 3, but it's not our priority at this moment, so it might take a while for us to start making apps for Quest 3

@@KIRI_Engine_App This is another example of what I was talking about. What you said makes perfect sense, but I feel like a lot of other companies would have not responded, or been not as honest with their answer.

@@LincolnWorld Thank you so so much!! Yeah, transparency is what we think one of the most valuable thing for today's startup. Please don't hesitate to let me know if you have any questions in the future haha

Hi there! Yes, the 3D model is directly compatible with Fusion 360, you can export 8 different file formats including USDZ, GLTF, FBX, OBJ, STL, etc..

@@KIRI_Engine_App Thanks! I will give the app a shot

@@Foxtrott_4 Anytime Fox! Let us know if you ever come across any questions or concerns while trying the app, shoot us an email at contact@kiri-innov.com

Good question! If you use an iPhone Pro that has LiDAR, the Object Capture mode can be quite accurate dimensionally. But if you don't use the iPhone with LiDAR, the models don't come with a real-world scale right off the box, but there are ways to manually scale it on 3D software such as fusion 360, our friend Kevin showed his technique in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-axdPIc6FqQU.htmlsi=kZgqt6f0VnxpQpN1&t=314

Hi trak! Thanks for the comment :) Haha, we are well aware there are other great players out there such as Luma, but believe it or not, KIRI and Luma are actually two completely different products targeting at completely different audiences. If you are looking for high-quality 3D models for actual 3D creation pipeline, KIRI Engine is the top of the line in terms of the mesh quality and other professional mesh features; But if you are looking to use 3D scan app for fun and capture everything about you to show off to your friends, Luma has a great user interface and features for that, but it won't produce good mesh for serious 3D workflows

Hi there! Thank you for your comment. I understand your frustration. The KIRI Engine was originally designed for phones, not for iPads. We do have plans to enhance the user experience for tablets, but this update won't be immediate. If you have an iPhone or Android phone, I encourage you to try the KIRI Engine on those devices, as that's where the KIRI Engine will really excel :)

Unfortunately no :( For local processing, you'd need a computer software like Metashape which would be 3000 dollars for the license

Thanks for the question! Unfortunately at this moment, it's not possible, haha we need to attract more native users to KIRI Engine :P But we do have plans to open this conversion feature online so other people can upload their 3DGS data to turn them into mesh

Hi there! Thanks for the question :) I'm not that familiar with CNC, but for 3D printer you can actually make 3D scans as STL formats, then export the STL formats to a slicer for 3D printing

Hey Mike! Thanks for leaving the comment man :) And believe it or not, it's a super common issue to many users who just started learning photo scanning. Due to the technological nature of photogrammetry, the simpler the object, the worse the result will be. If you have just started to learn photo scanning, I'd recommend you try to scan a piece of rock or wood because those objects have rich textures on their surfaces, which is a good thing for photogrammetry. Once you get a hang of the technology you can then explore other possibilities by trying to scan harder objects

Hi again :) Thank you so much for letting us know because without this comment, we wouldn't have realized the need of dark mode. Dark mode is on schedule now :) Fingers crossed

@@KIRI_Engine_App Oh well I don’t buy iPhone. I only use iPad Pro 12.9” and I always use iPad Pro because I have deaf/blind (low vision) you forget think about all of them hearing / blind and deaf/blind Look at your setting > Accessibility and everything list you can see. Also Magnifier camera too.

@@Blendermodeldeaf-ry5nz Ah I see! Thank you so much for this insight!!

Hey Ann, thanks for commenting :) Oh absolutely, you should try KIRI Engine app on your phone, photogrammetry scanning is free with unlimited number of scans. This kind of photogrammetry software normally cost your 3000 USD (i.e. metashape) Feel free to let me know if you have any questions while trying the app

@@KIRI_Engine_App I took photos from my phone and transferred them to my laptop. And I decided to upload a photo to try to see this object in their 3D view. I do this from a web browser. I'm pressing it- upload "Upgrade to KIRI Engine Pro Upgrade to KIRI Engine Pro to get access to KIRI Engine Web" Is it already paid? I'm from Russia, unfortunately, I can't pay for anything abroad right now. That's why I wanted to try it for free at least. Is it possible to do this? Do you have a more understandable step-by-step instruction on how to do this? I really want to learn 3d.

Yeah.. buti don't care of my 3d model of a random junk will be on their server

Hi Kangsan! Good questions. Actually, we can run Object Capture feature locally on the iPhone Pro and iPad Pro series, but for Samsung, we believe it has great CPUs however Android phone doesn't provide enough frameworks for us developer to develop graphic intensive computing which needs to draw the true power from a phone at low level. So unfortunately, the most universal solution we can think of is to provide a light-weight photogrammetry alternative on the iPhone Pro and use the cloud computing to ensure more users regardless of their phone can enjoy 3D scanning.

Thank youuuuuuu! Feel free to let me know if you have any questions when trying out the app :)
