Hah! Is this photogrammetry day on RUclips or what? I just finished and put up my own video, also using Reality Capture, and some other software. Great summary Clint, especially about merging together point clouds. It's a great way, regardless of software, to get a better quality mesh at the end. 🙂
William faucher released one as well today !!!
@@bkentffichter I did, I literally have an over three year old video on the subject as well 😄
people on youtube get so pumped about commercials. we should be critical and skeptical. like show me a livestream of a complete process.
Bryan Mitchell huh? Reality Capture didn’t pay me anything, nor are they a sponsor of my video in any sense. I paid for all my scans myself. I did get a license from 3DF Zephyr to their software, but they also had no insight or oversight into my video 🤷♂️ Before you question someone’s objectivity it helps to do your research first 😉
v b read what I wrote to Bryan above, I can’t speak for Clint, but my video is not a “commercial” and all I said in my video are my own opinions, nothing anyone has told me to say. Question objectivity all you want, but questioning things just because you have trust issues, and not actually valid concerns, seems like a good way to go through life paranoid and unhappy 🤷♂️
Some extra tips I've found photoscanning plastic figurines. If you want to scan an object that is reflective and contains a consistent flat colour (usually very bad for photoscanning) cover it in baby powder. This adds micro details to the mesh which helps the scan while being easy enough to clean up afterwards.
Thanks
@@user-wy3ng5hs3i RC is king for detail and speed.
@@user-wy3ng5hs3i Rc is worst for estimating camera poses though
Very good one, also you can use polarizing light. Also instead of baby powder you can use something like watercolors dispersed with a toothbrush for example. Anything goes really as long as it is uneven and adds contrast, mud, spray paint etc.
fantastic video clint! crisp presentation, easy to follow, interesting as hell.. you're crushing it :)

Awesome job Clint! Thanks for the fun and informative time. Keep doing you bud. You're totally kicking ass! Much love from Michigan
Woah! Love these videos Clint and can't wait to see what's next for you as a creator! Shot at 0:25 is fire my man
Nice scans, Clint! You're absolutely right, photogrammetry can become addictive. I always like to compare it with shooting on film- you go out exploring and capture something cool, return home and start to feel that rush of excitement once you sit down and start processing your images, and finally see what you got- and when it all turns out, hopefully you're happy with it!
Thats a perfect comparison!
Absolutely true.
@@pwnisher Hi Clint! one thing that i don't really understand is that some videos forbid you of moving the object you are trying to capture. however you turned your one wheel upside down and sideways. Does this have any negatice influence when the pictures get ported into realitycapture? this is my first time ever doing this and i just want to make sure i am doing it right :)
3d scanning is honestly the best. I am going to start using it more often, thank you for the great tutorial 😄
We love you Clint!!! Your energy is amazing and you're a huge inspiration! Keep doing you.
That tip for exporting masks to be able to combine all the different captures is amazing. I've been manually combining meshes for far too long. Thanks!
Is it faster to capture objects like this or to model them from scratch?
that really depends, for the most part this is much faster. Modeling the onewheel from scratch would take 6+ hours while this seems like it took around 1 minus the rendering process
this is such a high quality video and very advanced !!! I loved it - cant wait to try it out on my own
Happy holidays to you to man! thanks for all the awesome content :)
Great vid! Thanks Clint!
I gotta say man, I love how your enthusiasm shines through in your intros, takin' notes here!
you are killing it dude, keep it up
Literally photogrammetry in one wheels you have more than peak to my interest
Wow dude, thank you so much for your detailed explanation! Very nice to see you!
Happy holidays pwnisher 😼
I don't know a thing about 3D Scanning or 3D workflow, but you my man explain it so well it's incredible. Best and favourite 3D teacher ever! Keep it up my man 😁👊
That means so much! Thank you!
learning this and blender is one of my 2022 goals. thanks clint!
I believe in you!
Love it Clint. I tried photogrammetry a few years ago and always got sub par results. I am going to have to try it again following your guide. Beautiful scans son!
Feel free to write me too.
why are ppl so pumped about this vid . it’s a commercial and of course we don’t see the mess.
@@MrMadvillan you k?
Is it just me or does Clint come out with the exact tutorial I want each month?
Love it, great stuff clint
Great scans, great channel, great guy!!! Thanks Clint!
Thank you for this! Nice, concise, and easy to follow!
Oh, god! Best guide for this ever! I love that!
Giving that sick new course that’s coming out a run for it’s money
Wow, it's best video about photogrammetry i have seen yet
Yeeeeeeees! Always been excited about 3D scanning (since LOTR and the Troll, I guess). Finally an awesome guide on how to do this in high quality!
Heeeeck yeah!!
We know, we all needed a detailed photogrammetry Tutorial!!
Awesone Video man! Keep em coming!
Brilliant video Clint!
Love it brother 2 big photo capture tutorials in 1 day so much info 🤙🏿
Thank you so much for such an in-depth and inspiring tutorial!
Fantastic video. Thank you VERY much for sharing your knowledge!!
Great video! I have always been interested in photogrammetry. Will have to try this.
Amazing 👏🏾. Just in time
Thanks for your easy to follow explanations
Creative Shrimp also has a very extensive photogrammertry course coming out this week which is something im very excited about
Dude this was an awesome video! wow! thank you!!
I´m starting with the same set up and been using mesh room with nice results but CapReality seems to have more options, I´m going to look into that. I think it´s crucial to define the object and the area up front in your workflow. Scanning people outside will give you huge messy meshs of your sorroundings otherwise.
Congrats on the continued success of your channel man. Your videos are super thorough, informative, relaxing, and motivational. I miss you on Coridor a ton, but your new content is top notch. Glad you’re happy.
Many thanks for the kind words and support! I’m glad your enjoying the training :)
Thank you for your time and knowledge you share... ✌🏽
What a time to be alive!
Thank you! Presented very nicely
Thanks for making videos like this
it was really magic when it aligned two different sets of the wheel. I got sometime a problem RC doesn't align two sides of one photo set, for example something thin, like a biscuit, with really narrow edge.
Thank you so so much for that video!!! Love it. Wanted to get into photoscanning for so long!
Video suggestion from my side, UV Unwrapping and Retopoligizing things!!!
Thank you for the tips. Learn alot from it .
Been doing photogrammetry personally for over ten years and professionally for over 6. It's so nice to see both the infrastructure and hobby build into something we can finally start using.
Let's get this party started!
After two year this video is important to me than ever
Can we all just take a minute to admire Clints hair, looking handsome AF bud.
Great video as always!
Awesome video! Thank you!
I'm looking forward to this. My first attempt at photoscanning using my phone and meshroom made the chair look like it was getting snapped by Thanos 😄
This is sooo cool!
How long does it usually take you to create one of these models, start to finish?
This is a great resource, thank you so much for all the effort put into this.
Do you have a recommendation how to do a pbr conversion for the textures? My initial idea would be to use color selection in a tool such as Substance Painter to split up the different materials from the original color map and give them their respective material properties (amount of roughness, metalness, etc.). Do you even typically do that or do you often find the basic color texture to be sufficient to create a believable asset for a realistic environment?
I'm wondering the same thing
Hopefully I'm not too late to this, but what I do is to bake a high to low normal map also, and do a basic roughness map using a colorramp to roughness in Blender. That way, when I bring the model into Painter I have 3 basic maps. I'll then tweak them like you said, giving each material it's properties using tons of masks. It can be a little laborious, but the results are amazing.
Thanks for great tutorial for me! It is awesome really! :)
Fantastic video. Used meshroom with subpar results, then went with 3DF Zephyr, though I should give this software a shot. But question: How would you go about scanning large structures such as buildings in the most efficient way? I want to photoscan some campus buildings, but the only thing I could think of is using a drone which I don't have.
The easiest approach for smaller stuff is to have the object inside a photo tent on top of rotating disk.
I have once clicked a JVC truck like that. There was budget so we created a tent.
NICE 3D SCAN TUTORIAL EVER👍
Great video Clint, thanks! What would your recommend for colour managing your scan using a macbeth chart?
Wow nice tutorial Clint!
I went through this process a year ago and it took me forever to figure all this stuff out! I wish I could have seen this then. :)
Btw. quite astounding how similar Agisoft and reality capture are. Apart from the UI, it seems the process with chunks, reference points, masks and all that stuff is basically the same.
I wonder what the costs are for RC, can't really decypher their pricing site :D
very cool! I 3d model in C4D - I'll give this a go!
i never knew i subcribed into your channel i always see you at coeeidor crew
Man thats a good idea for the challenge, have a standard onwheel asset positioned in the middle, that start the frame and ends the frame in the same position , and onewheel could actually sponsor it, that would be amazing, each guy could change the onewheel style, different terrains or even stopped many things possible with onewheel centered...
Thank you, Clint!
Great tute!
you won a new sub.
Thank you so much for the amazing tutorial! One of the best tutorials I’ve seen, I can’t tell you how much I needed this info. Can I use a hasselblad H5D to capture the images?
you inspire mea lot bro
Thanks Clint! How do you handle roughness maps? The one wheel has different materials that have different reflectivite/roughness values. Thanks in advance.
You are so nice person Clint. Keep my sub and like. Nice and motivating content even for person like me who wants to start his journey with 3d wonders. Stay Healthy!
Yeah! Ty for this video buddy, love It! When another render challenge? 😍
Some good shit, nice job
If you have a mat part and a metallic part, how do you then make the metallic part more shiny than the other parts?
Great explanation by the way. Thanks.
Love you man
Gotchu my guy :)
good job!
I bumped into this video after seeing wren scanning a foot with his cellphone, i found it amazing and looked it up, who’d say one of the corridor crew guys would have a full guide on how to do it… I’m looking forward into making a 3D model of myself and my friends for vrchat
Is there a tool that would let me take screenshots in a video game to recreate a 3D environment? I want to have recognizable re-creations of many different game locations (doesn’t have to be anywhere near these detailed though) so that I can move a camera around the area and create video guides to help new players joining the game
muy buen video!! saudos!!
Great! you can manipulate it in Cinema 4d, Like with Voronoi Fracture? Or because of the poly amount it isn't possible.
A video of physical maintenance for those of us that are mainly on computers all day would be great.
I began an editor job recently, and am working on my 3D/VFX skills/gaming in my freetime, so a lot of my time is spent at my desk now. So yoga recommandations would be great
Going to take what I've learned here, and work on filming a mock keyboard commercial I've been wanting to do
great content 😘😘😘
Who else is waiting for a new community challenge? I just found out about them, and I cant wait to participate.
Can someone help me? I'm trying do import a brush from quixel bridge to blender and after saying it exported suceccfully I can't find it in blender. Thanks for tour time.
How about retopo'ing the asset properly and reprojecting the textures onto that? Reality capture or in the DCC-app?
Just curious. Have you attempted to use reality capture to capture a whole interior space using a camera?
I feel like a lidar scanner like a Leica might be a better solution for this, but I'm trying to find a workflow to do this with just a camera.
Do you think doing 2 concentric circles in a room from varying heights, while reversing the direction I'm facing in the room, to capture all detail would be a solution while adding varying parallax as I get closer to an object might be a solution?
Then just maybe setting a lot of control points via brightly colored tracking markers I have set around said room?
I have used poly cam but the results aren't up to par with reality capture. My end goal is to import a scan into Unreal engine to use as a set on an Led volume.
Thanks in advance!
Hey Thomas - absolutely you can do this. I've captured some interiors with incredible detail with photo-only scans. That said, if you can ALSO capture with a decent lidar scanner (and be sure to have it grab textures) you can combine both datasets and get the best of both. Photos alone can go a long way though but you will need to be disciplined in your capture - much more involved than walking around an object or turntable. Also likely will want to utilize a tripod and choose exposure carefully - multiple brackets if needed to capture full range, etc. You can run tests in RC for free so I'd suggest start by trying and seeing what you get. Your suggested approach is more or less what I do.. Circle around the room, back to the wall facing in, different heights, orbit around things in the room at varying heights, make sure you have a camera 'path' to go from wide to close up and try to think of a giving a lot of overlap and path for solver to join all the photos. If you have a big jump in position make sure you have a lot of overlap with other 'photo paths' so it can solve. Avoiding having to connect the dots later will make it all work much better. Try to get at least 3 or so angles on any feature you want, so if moving accross beamed ceiling make try to visualize every 'face' having at least a couple photos of coverage. Good Luck!
Gets all the way to the end think it's interesting and when the prices comes up think nah.
could this be used for manufacturing? photo scan and scale an object that is a little bit complicated for machining?
Is it recommended to rather video capture the model with the right settings and then export the video as png and use those png's for the scanning software ?
Would be much faster and easier I think
You could certainly give it a shot, but your resolution would be waaaay lower vs. using photos.
That was a lot of work bro.
This is awesome, really helps to do something I have been wanting to learn the moment I saw it demonstrated.
However, my first export I may have over done it, 4.97$, for this tiny, little, mini Watering Pot, 327 images, I suppose you live and learn. But it was extremely well detailed!
Funny thing, I found you from one of William Faucher videos, and funnier still, I knew you from Corridor Crew videos.
So awesome, thank you.
How about scanning something like a model car body i.e. plastic shell with thin walls. Would this technique work? Or does the object have to be solid? I was going to try scanning with Polycam. Great Video! Thank you!!
Episode 2 and 3 for scanning an indoor area for levels, and scanning a person and rigging it!
Excellent 👌
I loved the tutorial, but is there any app recommendation for taking photos
How to download this skateboard?
I want to analyze the resolution of the generated mesh.
Thanks
Just wondering:) What about the DOF with the lens (24-70mm) you are using. At that close distance not everything can be in focus. Isn't that a problem?
Ah, yes! A fellow polarized lens cap user! Man of distinguished taste as well as common sense!
Cheers!
