I formerly ran the rapid prototype lab at Sulzer Orthopedics. Now Zimmer. I used to create complex bone models from CT and MRI data that was translated to .STL. The technology used individual sheets of heat sealed and laser cut paper. LOM...Laminate Object Manufacturing. These models allowed the surgeons to plan the repair and replacement of old or traumatized joints before ever cutting the patient. It was quite an advantage to be able to see the bone before cutting was involved. That technology was primitive compared to today's 3-D modeling capability.

Essentially it's triangulation. The program compares similarities from different photos, understands that what it's looking at are the same things, but in different positions. Then it understands (heavy simplification) from the changes in position where the camera ought to have been in relation to the object, and from there can reconstruct the geometry of the object. In theory it's simple, in reality it's far more complex 🙂

You have some serious talent my friend. Had to give this video a like! You are a great teacher by the way. I learned soo much from this as I’m a novice to 3D printing
To avoid different light (exposing time, aperture) and different imaging scale (distance to the object, can cause also focus problems) and shaking problems, there is one magic key: don't move the camera - move the object! (if it's possible to move...) Get a used pottery wheel or any other "carousel" where You can set the Object on (to turn it) and put the camera on a tripod! Take videos with different camera hights. The resulting video quality will be much easier to process! (To make Your photo series even more precise, You can also put some angle marks around the outer rim of the wheel - and put a hand (vertical piece of wire or piece of cardboard, duct-taped on the bottom beneath the wheel) that indicates the scale - so You can turn Your object in precise angled steps!)
If you looked through the video you would've seen that I tried that method, and it's not without its issues. Firstly the algorithm in photogrammetry programs is heavily helped by the environment around the object you're scanning. By understanding the environment it can more easily understand the position of the camera, which in turn helps to understand the shape of your object. One way which can be more successful is using a greenscreen (like in Niels Provos' video I show a snippet of in my video), but if your object isn't sufficiently detailed that method will also be less than successful. I would rather recommend you take images with varying distance to your object. If there are parts with higher detail it can be very beneficial to take closeups of that area. The software should not have much issue stitching that together. Also the use of a tripod is entirely overkill as long as you work in good lighting so you can have shutter speeds on your camera fast enough to eliminate motion blur from shaking the camera. Finally I would not recommend using video for your scanning input. Even 4K video is lower in resolution (and more compressed, thus less detailed) than the photos even the simplest consumer digital cameras can take.
Wow this video really made me want to get a 3d printer! The artistic possibilities are practically endless!! Just the failed scans alone would be amazing as desk decorations.
I am quite old and find technology overwhelming. I am in Canada and have always used the traditional methods of mould making for any sculptures I have created.

What I particularly enjoyed were the many trials and errors as you figured our your process. It was useful in being realistic about the process and its complexities.

I do not generally give thumbs up or comment but thought I would let you know that I enjoyed your video and found it useful. I also want that bread! Take care Switch and Lever and thank you.
Interesting! I wonder if i's possible to use this technology for just creating a texture to project onto 3D models? I want to make 23D models from my Russian dolls and have no problems creating the models, the texturing is more comlicated though.
Great video, its been 2 years, since it was made, would you do a follow up video with updated new developments in both scaning and 3D printing hardware software, please?
Just curious of what it costs to have shapeways print the ring in silver? We are working on restoring a few vintage 1920’s Speedometers for cars and the old ones had originally been made of several pot metal parts, this would be a good way to have the parts replicated in aluminum?!!
Did you actually watch the video to completion? You don't need a 3D printer, you can order 3D prints from a wide variety of different online services, among them my favorite Shapeways. It helps if you have a 3D printer, but it's in no way shape or form required.
Nope. I don’t do long form 3d modeling tutorials or how to use programs in detail. There are many other people who do that much better than I do, and while I appreciate their videos making them myself is like pulling teeth.
2:57 Tip for noobs. Small aperture means large number on your camera. e.g. F20 (think of the number as a fraction of the lens, so F1.2 [1/1.2] is a wider aperture than F5.6 [1/5.6]) Use A - Aperture priority settings on DSLR. Nice vid.
I wonder how well something like a water based spray adhesive along with a rubbed on coating of talcum powder would work for taking care of reflective surfaces. On the plus side that should be easy enough to remove afterwards with something like goo-gone or other similar cleaners. Possibly even something like a hairspray may be enough, instead of a proper adhesive, then you could clean it off with soap and warm water.
Looking at this for the purposes of creating a respirator to fit the unique contours of a face to achieve a air tight fit. Thanks for the suggestions and thorough work. I subscribed!
Honestly I think that’s the wrong approach. The time required to scan a face and to adapt a 3D model to fit it properly would be far better spent in printing generic masks (in perhaps a few sizes) and rather thinking about the sealing interface material between mask and face. A soft and flexible material that fits against the face would be a better option, and would easily allow the masks to work on many different facial types. This also eliminates the uncomfortable hard plastic resting directly against the face.
@@SwitchAndLever Definitely was considering a soft material where skin contact would occur. A thought that came to me later was a full helmet, though that would have other bad effects on patient care. My goal was to utilize 3d printing or some kind of at home manufacturing to create usable PPE to combat the COVID-19 virus.
Oh, I think it's a worthwhile goal, I just don't think that 3D scanning, especially through photogrammetry would be the right approach due to the amount of manual post work you would need to do to even have a workable mesh to work with. The scale of the imported material won't be correct either, so you would have to compensate for that for each and every person you scan. In the amount of time you customize and print one mask for someone you could've likely printed ten masks that are not personalized.
You can try also to place the object (not too heavy) in a battery operated Motorized Display Rotate Stand ...is a very cheap option to get online. One camera, one display base.
There are rings like that on Ebay. Small silver with ruby eyes were popular among sixties fans. I got mine facing eye socket forward on a shelf in my den. Precious and cute, but so creepy!
1. Using photogramatry, how do you suggest taking the 50 pictures? 3 rows of 16 images (high, straight, and low) 22.5° appart with an additional vertical top down shot? ( I know I am still missing one.) 2. Does the photos for photo have to be exactly the same distance from the object? 3. Can you use photogramatry or lightscan to make a cheap lifesize model of your own body? 4. Can you modify the model after taking the pictures?
1 yes and no, I would suggest taking most on even increments all over to capture the general shape, but also take a few closeups on more detailed areas. A head may need more photos of the face than of the back of the head as it's more detailed. 2 no, but in some cases it can help the software. 3DF Zephyr has a setting called "urban" which helps with understanding that the photos are not taken from the same distance. 3 yes, as long as you find someone to take the photos for you. I wouldn't use structured light scanning as you're unlikely to stay still for that long. 4 of course, as you see me do with the ring in the video. It may be helpful to retopologize it if you want to do anything more meaningful than just resculpting in ZBrush or Sculptris though.
Very informative... and beautifully done. Especially liked your coverage of the failed attempts and process evolution. Most don't cover that and this is so vitally important for understanding. TY !!
Fantastic tutorial! I am a neophyte with zero 3D experience and a huge interest in learning about it. Until I found this video I was totally ignorant of how to create files. None of the videos about or instructions for 3D printers discuss files other than mentioning different softwares available. This step-by-step guide was a giant step for me towards understanding the process. I particularly appreciate the advice about spray painting the model in contrasting colors. I can't wait to try this!
This is so great! Thanks for sharing, I know that one day I'll need to scan something and print it on my 3d printer, this information would've help alot.
Qlone is a ios app that scans. I have just tested it once, and the result was... interresting. However, its a hint of things to come. How about testing the Qlone app?
As I’ve pointed out plenty of times already. Yes, that’s a swell idea, if my hands were the same size as when I was a kid. Nowadays I can’t fit that plastic ring even on my pinky, so an exact copy would be less than useless. Besides, if you order it from Shapeways that’s essentially what they do. They 3D print the wax and cast it for precious metals.
Can these programs ask directly for specific camera placements. So if you can position your camera and take pictures from the specific XYZ postions in space around the object, that the computation of the shape to be exceptional even with shiny or complicated surfaces
A funfact: The upside down house at 18:02 is placed in Szymbark (Poland), next to the place where the world longest board from one tree has been cut out :)
Thanks for sharing! I bought an iPad with lidar and was looking to use it to scan a piece of equipment at work. The piece is large 12 plus meters high but the part with the most detail is only 1 meter and up to 2.5 meters high. Any tips and tricks would be useful.
All the photogrammetry that you have done is from outside a model. I was wondering if you could do the same internally. For example the interior of a house.
How can you be sure the ring fits? Can you increase/decrease size so it will be f.ex x number of millimeters in diameter? Is this done in the 3D printer software? (Sorry for asking, just wanting to obtain information before I will buy a 3D printer). Sometimes it could be important to create a copy of something in 100% equal size too.
I measured a ring that I knew fit and scaled the ring in a 3D program (not the 3D printer software) before sending it off to Shapeways to be printed. You cannot simply buy a 3D printer, you have to learn how to use at least basic 3D software as well. Blender would suffice, but other software such as CAD packages or more advanced software may be required as you grow.
Can photogrammertry be used to scan a toy and turn it into a Pepakura pattern to then make a cosplay. Please keep the videos coming I find the subject interesting.
Because you’d run the risk of introducing surface texture distortion unless you use a very fine sand, basically something like talcum powder. If you continued looking you see that i ended up painting the surface to get around this issue.
Along with shapeways, it's worth mentioning 3d hub for more simple plastic prints, and it's often cheaper. Also, I'm pedantic, and I like to say stereophotogrammetry to differentiate it from older style photogrammetry used for mapping.
Well yeah, photogrammetry in its core is just about taking measurements from photos. The first patent related to photogrammetry was in the 19th century already. There is also videophotogrammetry. However, photogrammetry is already a mouthful, I'm not going to make the word even longer to say 😄
Would you consider making the 3D model of the head at 4:28 available for download? the "reality disintegrating" one? it seems like a fun thing to play around with with 3D animation
Sure thing, I just uploaded that one, another failure (which is my favourite of the bunch), the finished model without the table, and the final one with the textures, to Sketchfab. You can download them here: sketchfab.com/switchandlever
One thing you might (me?) try is textured paint. There's lots on the market that are best known for non-slip surfaces. So if you paint the tops of stairs, there's "sand" in the paint that allows your feet to grip it. That might work best.....
Depends on the size of the grit, as it may actually be picked up by the scan. Look how fine details were picked up on the scan of the bread for instance.
it's pretty fine....like 220 grit sandpaper. But if it is quick and easy to get an accurate scan, it looks like smoothing it out in zephyr would save a lot of trial and error. There's also paint like you did with black and white. It's supposed to look like granite but really just looks speckled. Check out Krylon, they have all kinds of specialty paints that might help.
Smoothing is a last resort though as it has a tendency to also kill fine detail. The granite paint may be interesting, if it's fully matte, otherwise won't work well because of highlights. Can't really find Krylon paints over here though.
I hear you. I convert photos into 3d images to run on a CNC and the software I use turns each pixel into a point: high or low..soon as you start manipulating it you lose that detail.
I have recently started making rc truck vaccum molding body and this is a great way for mr to cut some major working time on making 3d model. Thank you sir!👍💪👌
@@christopherbradbury9124 hi. Thanks to show interest in my project. Ill make a short story: yes it work, but not on a scale I can sell them. The production cost is hight and at the end the result is not that great. Its easy to make a body with a thin plastic, but with a thicker plastics it's not the same. I dont have enought experience right now. But its going foward even with that covid19 virus. I also dont feel confortable salling the same body as traxxas. I also want to add that I started this project last September... perfections needs time. Thank you for your comments. Stay safe👍
Can you expand more on the 3d photobooth when the cameras are synced up? I had my picture taken in one of them in Germany 14 years ago. I've always thought it wouldn't be that difficult to make but I haven't been able to find commercially available booths or any resources for documentation. Thanks in advance. Lance
Reflections are frequently a problem in photography and videography, so check out corresponding local forums and other such information sources for what people around you use as a "dulling spray" to remove them. Usually you'll find that hair care products are used, they are cheap, you can source them anytime and don't need to wait for shipping, and they can usually be washed off with warm water and soap, unlike paints which are permanent. Spraying a strong-hold hairspray from a larger distance and at an angle will make for a matte translucent surface as it sets in clumps, and blonde and highlight hair sprays are available too, pigmented in various colours.
I was just wondering about the paint used on the head. It was a nice method, but as the goal was to copy a "precious object", I doubt you'd want to use any permanent substance on it. Your suggestion seems very interesting.
Yeah, I learned about this about 20 years ago while working on a photo shoot. They were getting glare off chrome baskets and saw the guy walking around with a can of hair spray. It costs about 1/4 what the "official" dulling spray does and is available just about everywhere. It does just wipe off with warm water/cloth.
I liked your video very much. The details of the struggles to perfect 3D printing/reproductions has been a trial and error only a few understand. There were times when you would think it's not even possible but every little advance no matter how insignificant promised a perfect end result somewhere in it's future. From idea to tangible reality. Thanks for sharing! :-)
so very cool. thank you! i am embarking in a similar project soon and this helps immensely.... also, did you ever end up putting this on shapeways because OMG.
I'm not sure what you mean with a "3d photo", as that's not really a thing in this context. But no, you cannot. You can, in some softwares, help it out by matching points together manually. It is an extremely tedious procedure though.
Nope, unfortunately due to it holding a personal space to me that will not happen. If the interest is big enough I may post it for sale on Shapeways though, so people can buy it in silver or other materials.
Gives a whole new subset of use-cases for camera's expensive and cheap. And skullrings definitely aren't tacky. Yours has an awesome story connected to it. Cheers man, thanks for sharing! Have a few coffee's on me!
excellent overview! I have a NextEngine scanner at work and while it does a good job, as long as you follow the age old adage, "crap in, crap out", it lacks at providing a texture map to use afterwards. Have you found any work arounds for this?
Really? The one I used gives a texture map. Well, really, it gives a bunch of different texture bitmaps applied haphazardly on the mesh to make up the whole, so it's impossible to edit the texture map should you need to. Using 3dsmax or a similar package you could bake the texture and get another UVW projection though, and consolidate it into a single bitmap.
Switch & Lever yeah, I see those low res images it creates, clearly I don’t know what to do with them. There really is a lack of videos on that scanner out there.
another rule of thumb for photogrammetry is that the photos overlap each other by 60%, source is that i work with drone photos of big areas for surveying, we use the software agisoft, there is a free version of it but you can export your work with it.
Agisoft is good, but I don't know if I'm using it wrong since all my results from it are much worse than 3DF Zephyr, when using the same source material. The results tend to be more noisy and more fragmented.
Im kinda new to agisoft, but i would recommend the 60% overlapped photos, also something i learned is that pixels is everything and white pixels are basically dead ones. So the optimal camera settings is kinda counter intuitive, you should have as low ISO setting as you can, fast shutter-speed. Also using a relatively narrow lens also helps (18-24mm).
@@RayRand It's on their github github.com/alicevision/meshroom/releases/tag/v2018.1.0 I've used it a few times now and if you get the images right its the bomb
Sculpting and molding won't create a copy of what you have, it will make your interpretation of it. You could copy a document in a copy machine, scale it up and scale it down if need be, but you wouldn't call you rewriting that document by hand a copy. As for satisfying, that's for anyone to decide. If I had the artistic ability to do sculpting on this level I'm sure it would be very satisfying, but as it is I don't, so it would be an exercise in frustration more than anything, notwithstanding that I don't have the facilitates to cast silver.
Switch & Lever you are right, I have the prejudice of being an artists when I said that! For 1 to 1 scale mold copies I have had ver nice results with spinning the mold wrapped in a towel (centrifugal force pushes the metal down the mold, opening facing the spinner, only minimal force required). Another ancient method is sticking a half cut potato to the heated top of the mold immediately after spilling in the metal. I’ve done pretty smooth copies of plasticine sculptures (make sculpture, sink into it thin plastic foil dividers at strategic places where you want the 2 or 3 parts of your mold to open, then smudge plaster onto sculpture creating the mold..) with spilling soldering metal into them :P
Switch & Lever - thanks for such a great video. Really got me inspired, with practical help on how I can get going. How did you get such a good finish on the miniature bread at the end - is it painted with airbrush?
I formerly ran the rapid prototype lab at Sulzer Orthopedics. Now Zimmer. I used to create complex bone models from CT and MRI data that was translated to .STL.

Meshroom is the new big dog. No configuration at all, just drop the images and you're good. The scans are far superior than any other programs too!

Could you reduce the problems with scanning reflective surfaces using a circular polarising filter on your camera to eliminate reflected light?
Great video, its been 2 years, since it was made, would you do a follow up video with updated new developments in both scaning and 3D printing hardware software, please?
Wow, you are excellent. Good teaching style - you are smart, you get to the point, and explain clearly. Thanks
Just curious of what it costs to have shapeways print the ring in silver?
We are working on restoring a few vintage 1920’s Speedometers for cars and the old ones had originally been made of several pot metal parts, this would be a good way to have the parts replicated in aluminum?!!

"I scanned bread"
"How. Much?"
"I have done nothing but scan bread for 3 days"
Great overview of these technologies and just about enough depth to it. Love the humor as well!
How about the iPad Pro and it's lidar scanner?
Good Video! Really good Idea with the dots on the objects! Also good to see a comparison between the programms out there!
Did you actually watch the video to completion? You don't need a 3D printer, you can order 3D prints from a wide variety of different online services, among them my favorite Shapeways. It helps if you have a 3D printer, but it's in no way shape or form required.
@@SwitchAndLever Yeah, im sorry, yesterday was a bit of an emotional day for me, im sorry c: Im actually going to change the comment xD
Switch & Lever bad acne is also good if your doing a face or buttocks
could you maybe show us in another video how to get the model from 3df zephyr into a cad program and patching it/making it solid?
Nope. I don’t do long form 3d modeling tutorials or how to use programs in detail. There are many other people who do that much better than I do, and while I appreciate their videos making them myself is like pulling teeth.
2:57 Tip for noobs. Small aperture means large number on your camera. e.g. F20 (think of the number as a fraction of the lens, so F1.2 [1/1.2] is a wider aperture than F5.6 [1/5.6]) Use A - Aperture priority settings on DSLR. Nice vid.
I wonder how well something like a water based spray adhesive along with a rubbed on coating of talcum powder would work for taking care of reflective surfaces. On the plus side that should be easy enough to remove afterwards with something like goo-gone or other similar cleaners. Possibly even something like a hairspray may be enough, instead of a proper adhesive, then you could clean it off with soap and warm water.
Looking at this for the purposes of creating a respirator to fit the unique contours of a face to achieve a air tight fit. Thanks for the suggestions and thorough work. I subscribed!
Honestly I think that’s the wrong approach. The time required to scan a face and to adapt a 3D model to fit it properly would be far better spent in printing generic masks (in perhaps a few sizes) and rather thinking about the sealing interface material between mask and face. A soft and flexible material that fits against the face would be a better option, and would easily allow the masks to work on many different facial types. This also eliminates the uncomfortable hard plastic resting directly against the face.
@@SwitchAndLever Definitely was considering a soft material where skin contact would occur. A thought that came to me later was a full helmet, though that would have other bad effects on patient care. My goal was to utilize 3d printing or some kind of at home manufacturing to create usable PPE to combat the COVID-19 virus.
Oh, I think it's a worthwhile goal, I just don't think that 3D scanning, especially through photogrammetry would be the right approach due to the amount of manual post work you would need to do to even have a workable mesh to work with. The scale of the imported material won't be correct either, so you would have to compensate for that for each and every person you scan. In the amount of time you customize and print one mask for someone you could've likely printed ten masks that are not personalized.
You can try also to place the object (not too heavy) in a battery operated Motorized Display Rotate Stand ...is a very cheap option to get online. One camera, one display base.
I address this in the video and why it’s not necessarily a good idea to spin the object rather than move the camera.
There are rings like that on Ebay. Small silver with ruby eyes were popular among sixties fans. I got mine facing eye socket forward on a shelf in my den. Precious and cute, but so creepy!
1. Using photogramatry, how do you suggest taking the 50 pictures? 3 rows of 16 images (high, straight, and low) 22.5° appart with an additional vertical top down shot? ( I know I am still missing one.)
2. Does the photos for photo have to be exactly the same distance from the object?
3. Can you use photogramatry or lightscan to make a cheap lifesize model of your own body?
4. Can you modify the model after taking the pictures?
1 yes and no, I would suggest taking most on even increments all over to capture the general shape, but also take a few closeups on more detailed areas. A head may need more photos of the face than of the back of the head as it's more detailed.
2 no, but in some cases it can help the software. 3DF Zephyr has a setting called "urban" which helps with understanding that the photos are not taken from the same distance.
3 yes, as long as you find someone to take the photos for you. I wouldn't use structured light scanning as you're unlikely to stay still for that long.
4 of course, as you see me do with the ring in the video. It may be helpful to retopologize it if you want to do anything more meaningful than just resculpting in ZBrush or Sculptris though.
Switch & Lever thank you so much for your reply
Very informative... and beautifully done. Especially liked your coverage of the failed attempts and process evolution. Most don't cover that and this is so vitally important for understanding. TY !!
So true, wish more tutorials had this approach (not only showing when everything turns out perfect).
Do you think maybe a macro lens could help with the photogrammetry of the ring?
I would love if you showed how to take the 3D model to the 3D printer?
I’ve used LiDAR scanners like faro for scanning sets and locations for movies and visual effects. They are great tools but it takes time…
Fantastic tutorial! I am a neophyte with zero 3D experience and a huge interest in learning about it. Until I found this video I was totally ignorant of how to create files. None of the videos about or instructions for 3D printers discuss files other than mentioning different softwares available. This step-by-step guide was a giant step for me towards understanding the process. I particularly appreciate the advice about spray painting the model in contrasting colors. I can't wait to try this!
This is so great! Thanks for sharing, I know that one day I'll need to scan something and print it on my 3d printer, this information would've help alot.
this editing is unreal. bravo
Qlone is a ios app that scans. I have just tested it once, and the result was... interresting. However, its a hint of things to come. How about testing the Qlone app?
With app Bellus3D and iPhone you can scan your head and export the mesh in a quite high définition and also textures coordinates
While you can scan it saying it's "high definition" is pretty exaggerating it I'm afraid.
For the ring: make a silicon mold, cast in wax, use the lost wax method to cast the ring in any metal you like. Thoughts?
As I’ve pointed out plenty of times already. Yes, that’s a swell idea, if my hands were the same size as when I was a kid. Nowadays I can’t fit that plastic ring even on my pinky, so an exact copy would be less than useless.
Besides, if you order it from Shapeways that’s essentially what they do. They 3D print the wax and cast it for precious metals.
Can these programs ask directly for specific camera placements.
So if you can position your camera and take pictures from the specific XYZ postions in space around the object, that the computation of the shape to be exceptional even with shiny or complicated surfaces
A funfact: The upside down house at 18:02 is placed in Szymbark (Poland), next to the place where the world longest board from one tree has been cut out :)
THis video is the best video about 3d printers, scanners and softwares.
Best 3d scanning video ever
How to decide the scale? Should I add a coin with known size?
Loved the video. The ring isn't tacky, it's cool, and it has history and meaning.
Thanks for sharing! I bought an iPad with lidar and was looking to use it to scan a piece of equipment at work. The piece is large 12 plus meters high but the part with the most detail is only 1 meter and up to 2.5 meters high. Any tips and tricks would be useful.
All the photogrammetry that you have done is from outside a model. I was wondering if you could do the same internally. For example the interior of a house.
Great intro and presentation on 3 - D printing. Also useful for those interested in entry level 3 - D printers.
@@SwitchAndLever Sorry. Fixed my comment and thanks for letting me know it was weird! Happy summer!
How can you be sure the ring fits? Can you increase/decrease size so it will be f.ex x number of millimeters in diameter? Is this done in the 3D printer software? (Sorry for asking, just wanting to obtain information before I will buy a 3D printer). Sometimes it could be important to create a copy of something in 100% equal size too.
I measured a ring that I knew fit and scaled the ring in a 3D program (not the 3D printer software) before sending it off to Shapeways to be printed. You cannot simply buy a 3D printer, you have to learn how to use at least basic 3D software as well. Blender would suffice, but other software such as CAD packages or more advanced software may be required as you grow.
"Unshaped Hipster"
hahahaha, I died
Superb tutorial! I learned so much and finally feel ready to try my first photogrammetry project. Thanks
Is there any reason you couldn't mount the object on the end of a post so you can get more and better shots from below?
Can photogrammertry be used to scan a toy and turn it into a Pepakura pattern to then make a cosplay. Please keep the videos coming I find the subject interesting.
The printed bread surely does look amazing and also the rest of the video looks great! Thanks.
Cheers, I appreciate it!
You sir got yourself a new subscriber. Also sticking a good flash light to the camera would solve the shadow problem.
4:48 Why not covering the figure with hairspray and stick a thin coat of sand to it?
Because you’d run the risk of introducing surface texture distortion unless you use a very fine sand, basically something like talcum powder. If you continued looking you see that i ended up painting the surface to get around this issue.
I love this age,and seeing so much creative people on UA-cam 😁👍 it has become a hobby which inspires me when i make music. Stay creative!
That ring turned out really nice.
what would you recomend to scan trading cards like basketball cards to evaluate condition before sending off for grading which is $75 a card
I was thinking with the iPhone new background remover it could help get a clearer image
Skulls are awesome. I made a skull with sculptris an eventually i made a aluminium cast from it. Now I have a skull walkin cane that i do not need.
Of course you need it! Who wouldn't need one!?
Skulls are trite and overused. I fail students who use them unless it's something new and superior. That's rare. REALLY rare.
Live and let live :)

Along with shapeways, it's worth mentioning 3d hub for more simple plastic prints, and it's often cheaper. Also, I'm pedantic, and I like to say stereophotogrammetry to differentiate it from older style photogrammetry used for mapping.
Well yeah, photogrammetry in its core is just about taking measurements from photos. The first patent related to photogrammetry was in the 19th century already. There is also videophotogrammetry. However, photogrammetry is already a mouthful, I'm not going to make the word even longer to say 😄
Haha, yeah, I don't blame you. Whenever I say it, people look at me like I'm speaking gibberish.
Would you consider making the 3D model of the head at 4:28 available for download? the "reality disintegrating" one? it seems like a fun thing to play around with with 3D animation
Sure thing, I just uploaded that one, another failure (which is my favourite of the bunch), the finished model without the table, and the final one with the textures, to Sketchfab. You can download them here: sketchfab.com/switchandlever
Fantastic! Thank you!
One thing you might (me?) try is textured paint. There's lots on the market that are best known for non-slip surfaces. So if you paint the tops of stairs, there's "sand" in the paint that allows your feet to grip it. That might work best.....
Depends on the size of the grit, as it may actually be picked up by the scan. Look how fine details were picked up on the scan of the bread for instance.
it's pretty fine....like 220 grit sandpaper. But if it is quick and easy to get an accurate scan, it looks like smoothing it out in zephyr would save a lot of trial and error. There's also paint like you did with black and white. It's supposed to look like granite but really just looks speckled. Check out Krylon, they have all kinds of specialty paints that might help.
Smoothing is a last resort though as it has a tendency to also kill fine detail. The granite paint may be interesting, if it's fully matte, otherwise won't work well because of highlights. Can't really find Krylon paints over here though.
I hear you. I convert photos into 3d images to run on a CNC and the software I use turns each pixel into a point: high or low..soon as you start manipulating it you lose that detail.
the best video of 3d scanning of all time on youtube! thank you very much!
I have recently started making rc truck vaccum molding body and this is a great way for mr to cut some major working time on making 3d model. Thank you sir!👍💪👌
@@christopherbradbury9124 hi. Thanks to show interest in my project.
Ill make a short story: yes it work, but not on a scale I can sell them. The production cost is hight and at the end the result is not that great. Its easy to make a body with a thin plastic, but with a thicker plastics it's not the same. I dont have enought experience right now. But its going foward even with that covid19 virus.
I also dont feel confortable salling the same body as traxxas.
I also want to add that I started this project last September... perfections needs time.
Thank you for your comments.
Stay safe👍
Can you expand more on the 3d photobooth when the cameras are synced up? I had my picture taken in one of them in Germany 14 years ago. I've always thought it wouldn't be that difficult to make but I haven't been able to find commercially available booths or any resources for documentation. Thanks in advance.

@Switch & Lever 17:26, how it's possible that 3D print is colorful?
Look at the Shapeways website and the description of their colored sandstone material for a good explanation.
thank you!!
Reflections are frequently a problem in photography and videography, so check out corresponding local forums and other such information sources for what people around you use as a "dulling spray" to remove them. Usually you'll find that hair care products are used, they are cheap, you can source them anytime and don't need to wait for shipping, and they can usually be washed off with warm water and soap, unlike paints which are permanent. Spraying a strong-hold hairspray from a larger distance and at an angle will make for a matte translucent surface as it sets in clumps, and blonde and highlight hair sprays are available too, pigmented in various colours.
I was just wondering about the paint used on the head. It was a nice method, but as the goal was to copy a "precious object", I doubt you'd want to use any permanent substance on it.
Your suggestion seems very interesting.
Yeah, I learned about this about 20 years ago while working on a photo shoot. They were getting glare off chrome baskets and saw the guy walking around with a can of hair spray. It costs about 1/4 what the "official" dulling spray does and is available just about everywhere. It does just wipe off with warm water/cloth.
I liked your video very much. The details of the struggles to perfect 3D printing/reproductions has been a trial and error only a few understand. There were times when you would think it's not even possible but every little advance no matter how insignificant promised a perfect end result somewhere in it's future. From idea to tangible reality. Thanks for sharing! :-)
the photogrammetry evaluations are hilarious!
so very cool. thank you! i am embarking in a similar project soon and this helps immensely.... also, did you ever end up putting this on shapeways because OMG.
You know whats funny is you say the bread has no use but its useful as a goal to acquire in wargaming as a food source lol great video btw
Very good and useful video ! Next I'm going to have to learn to turn my Kinnect into a 3d scanner...
You did an excellent job with this video. Thanks!
I have one of those old next-gen's how did you get it running? Did you use their proprietary software?
Yes, that is the only way. I contacted their support which was very helpful in getting the software up and running.
Thank you for this gem of educational content.
Im just a beginner to 3D printing and could learn alot from this video. Thx alot
Can you import a 3d photo into this sort of software, where points are already matched? To give it a little boost maybe.
I'm not sure what you mean with a "3d photo", as that's not really a thing in this context. But no, you cannot. You can, in some softwares, help it out by matching points together manually. It is an extremely tedious procedure though.
The skull ring model would be awesome! Please let me know if you post it!
Nope, unfortunately due to it holding a personal space to me that will not happen. If the interest is big enough I may post it for sale on Shapeways though, so people can buy it in silver or other materials.
Gives a whole new subset of use-cases for camera's expensive and cheap. And skullrings definitely aren't tacky. Yours has an awesome story connected to it.
Cheers man, thanks for sharing! Have a few coffee's on me!

Hi
Is this possible with a 360 camera? Then you are certain you have all angles of the objest.
there have been some quite interesting, and spooky, animations done using this technique....
excellent overview! I have a NextEngine scanner at work and while it does a good job, as long as you follow the age old adage, "crap in, crap out", it lacks at providing a texture map to use afterwards. Have you found any work arounds for this?
Really? The one I used gives a texture map. Well, really, it gives a bunch of different texture bitmaps applied haphazardly on the mesh to make up the whole, so it's impossible to edit the texture map should you need to. Using 3dsmax or a similar package you could bake the texture and get another UVW projection though, and consolidate it into a single bitmap.
Switch & Lever yeah, I see those low res images it creates, clearly I don’t know what to do with them. There really is a lack of videos on that scanner out there.
Am totally enjoying Ur sense of humor with what could have been a rather challenging project! What does that ring mean to U?
another rule of thumb for photogrammetry is that the photos overlap each other by 60%, source is that i work with drone photos of big areas for surveying, we use the software agisoft, there is a free version of it but you can export your work with it.
Agisoft is good, but I don't know if I'm using it wrong since all my results from it are much worse than 3DF Zephyr, when using the same source material. The results tend to be more noisy and more fragmented.
Im kinda new to agisoft, but i would recommend the 60% overlapped photos, also something i learned is that pixels is everything and white pixels are basically dead ones. So the optimal camera settings is kinda counter intuitive, you should have as low ISO setting as you can, fast shutter-speed. Also using a relatively narrow lens also helps (18-24mm).
@@Jellooze Thanks for the tips from a proper photographic perspective!
Since this video got released, Meshroom is probably the best bet for free photogrammetry
All I see on their site is downloads of 3d models, I don't see any actual software.
@@RayRand It's on their github github.com/alicevision/meshroom/releases/tag/v2018.1.0 I've used it a few times now and if you get the images right its the bomb
Wow how did you paint the bread? It looks great!
Anyone know how he got LIDAR data set 13:32 do you have to be logged in for that?
Finally, sculpting and molding may be quicker and more exciting and satisfying than all this ?
Sculpting and molding won't create a copy of what you have, it will make your interpretation of it. You could copy a document in a copy machine, scale it up and scale it down if need be, but you wouldn't call you rewriting that document by hand a copy.
As for satisfying, that's for anyone to decide. If I had the artistic ability to do sculpting on this level I'm sure it would be very satisfying, but as it is I don't, so it would be an exercise in frustration more than anything, notwithstanding that I don't have the facilitates to cast silver.
Switch & Lever you are right, I have the prejudice of being an artists when I said that! For 1 to 1 scale mold copies I have had ver nice results with spinning the mold wrapped in a towel (centrifugal force pushes the metal down the mold, opening facing the spinner, only minimal force required). Another ancient method is sticking a half cut potato to the heated top of the mold immediately after spilling in the metal. I’ve done pretty smooth copies of plasticine sculptures (make sculpture, sink into it thin plastic foil dividers at strategic places where you want the 2 or 3 parts of your mold to open, then smudge plaster onto sculpture creating the mold..) with spilling soldering metal into them :P
I'm curious to know if lidiar on new phones will make this much easier now
The answer is yes
Ive learned so much from this video. Much more than what ive initially expected from the title. THANK YOU.
Switch & Lever - thanks for such a great video. Really got me inspired, with practical help on how I can get going. How did you get such a good finish on the miniature bread at the end - is it painted with airbrush?
It’s 3D printed in color with Shapeways. I did nothing to it after they printed it and shipped to me.
