There's likely some actual Nyquist-Shannon ish corollary that will tell you how much higher your scanning res has to be than your printing res, but 2x is probably a safe bet. Not to mention "accuracy" tells an imprecise story. Does it mean that the best case scenario every point is at most 0.1mm from where it should be? That doesn't mean the same thing as "accurately resolves features larger than 0.1mm³".
Because buying the models even at GW prices is likely cheaper than the time and effort necessary to do a good job of printing them. Model piracy does occur but it takes the from of Chinese recasters making molds directly from the model sprues. That all being said there is a market for this and my guess is the BOM cost of the hardware necessary to make a 3D scanner capable of resolving the detail of a tabletop mini is in the $10-$30 range right now. No way there's enough market to foot the bill of SW dev tho.
No because 3D scanning is really, really hard. Much much more complex than 3d printing. There's no fool-proof way of determining the position and normal of a surface point other than to touch it. All EM based techniques must contend with the wide gamut of different interactions common materials will have with a given wavelength. Not to mention occlusion.
The V2 (Structure Core) has a built in IMU and is much better at keeping tracking. The quality of the USB link between the sensor and the computer also makes a big difference. (not an expert in this particular area) but iirc USB is like TCP in that if a packet is missing or corrupted it'll ask for it to be resent, it seems like the Structure sensors are quite sensitive to this and missing more then a few frames leads to alignment issues. That being said I wouldn't call the experience user friendly on any level, their software is really really bad too, I've had to write some tools to modify their save files so that I can rotate the reconstruction area because that's not a feature of the software. Definitely strongly dis-recommend buying one.
Super cool stuff, anyone who's dug into this know how the integration for the actual measurement works? Would it be possible to use with some shunts or hall effect sensors for DC applications with a little electrical shoehorning? I run about half my stuff off DC directly for increased efficiency and save that this would be perfect.
It's easy to do with a smartphone and you usually don't even need a calibration object. A software like Metashape or Meshroom can infer the lens transform and position of the camera from enough photos of the same object from different angles. The small smartphone optics actually help you by giving you a deeper DoF.
Not the best example but this http://koanlabs.org/vignettes.html rock is ~5 cm tall and my best guess is the minimum detectable feature size is about 10 microns.
EDIT: Sorry to be clear the definition of easy here is "as easy as most photogrammetry", to get good results you will universally do a lot of knob twiddling, waiting and cleaning up broken bits of mesh unless all you do is scan rocks. Scanning rocks is easy.
I am calling for a refactor, not anarchy. I will go on record as saying that we would be better off as a society with drastically reduced intellectual property protections, especially along the temporal axis. You shouldn't be able to hold onto IP of any sort for more than a decade or so under any circumstances.
Fuck Getty Images. Fuck IP law. Fuck copyright. All that shit needs a massive refactor. I can't bear to think about how much harm has been done to software and human reality in general by lawyers and MBAs seeking to extract the maximum amount of value from things.
I'm glad things like this exist, but so sad that they need to.
EDIT: and as one commenter astutely pointed out, fuck Pintrest too, a perfect example of the hubris of SEO focused trashes with no morals or sense of personal responsibility; degrading the commons for their own gain
I very much appreciate STPIHKAL helping me get started exploring this stuff. I'll admit that the library itself was a bit intimidating. I ended up not using it and just wrapping the protocol for the particular toys that were of interest to me in about 40 lines of JS in order to implement chrome's experimental `writeValueWithoutResponse`. I'm pleased to report has a dramatic effect on latency. I wish I could contribute back but the code is just over-my-head complicated.
Fair enough, I was more thinking at the time I wrote the comment that people's collective decision to enable these business models was the "playing stupid games" aspect. I could have been less grumpy and more clear about it.
It depends on your workflow I suppose. It has a catalog module that lets you tag images with a color, a star rating and inspect the image easily at 1:1. That's basically all I care about so I have no problems with it. I generally only keep the most recent 100 GB of photos or so locally and I have a decent organization system using folders so I don't lean on it too heavily.
Play stupid games, win stupid prizes. I absolutely hate the SaaS model, the incentives are never in your favor as a customer.
In case anyone is looking to ditch Lightroom I can't recommend the FOSS alternative RawTherapee strongly enough. It's got a number of features I now find indispensable. I particularly find it easy to use to get that nice rounded off highlight quality film has using RT. I made the swap years ago and have never missed LR.
I second this. I've got an old iPod and I go on walks daily listening to albums, playlists, sometimes just queuing stuff up on the fly as the mood strikes me. Never skipping a song that starts playing.
Tetris and Quake 3 vs bots also work very well to calm my mind so that I can zone into the music itself. YMMV
IIRC, the only reason it's not called that is some inane IP bullshit. "Dota 2" officially but Defense of the Ancients 7.25 in the hearts and minds of anyone who's been around for the past decade and a half.
Awesome! Thanks for being here to answer questions, I've got a few for ya.
The big quad thing is just to ensure heading stability? Does that imply that the rocket lights and drops at roughly the same time so there's no chance for it to tumble out of it's desired orientation? Are you going to blast all the props immediately before launch to get it to swing into a more vertical position? How much control authority do you actually have with the air so thin up there?
I made a quick little userscript that allows you to attach tags to users on HN. There's pretty much no documentation, I didn't really expect to release it, but it puts a little [t] next to usernames on HN and you can click it to add tags that persist in localstorage and show up next to that user wherever they post on HN. Feel free to use it and adapt it however you like. Only tested on Firefox and I'm sure it's full of bugs and unintended side effects!
Yo what's going on here? Is this some sort of misinformation campaign? To what end?? There's been a number of comments making this claim even though there's no reason to suggest this was the case.
Eternal September sucks, but Urbit has traded "ability to ever be relevant or gain significant momentum" for "no eternal September". It doesn't strike me as a pragmatic choice, then again Urbit is prehaps better viewed as an art project pursuing the ultimate navel-gazing extremes of NIH syndrome, and when viewed in that light the choices they make start to make a lot more sense to me.
No it's not an odd choice. It doesn't have to be to be better or more efficient now. It's meant to be one step toward a future where we're not burning fossil fuels.
Wait what? Aren't the benchmarks we're seeing pop up all over today saying that the 5950X is about 18% better than the 10900K in single core workloads? How do you figure that it would be equivalent to the LAST gen from Intel?
At the end of the day all electronics are just space heaters with interesting side effects. It's getting cold and I'm using my GPU to heat my living space, it just happens to emit computation as well. Gotta keep gaming to capture the excess value!
Undervolting can work WONDERS. Especially if you get lucky with binning. I'm running the i7 in my little 13" convertible with a ~140mV undervolt, which is the difference between unplayable and 90 pegged in DCS and War Thunder (flight sims) in VR (w/ eGPU). It's also almost an extra hour of battery life when I'm just browsing the internet or whatnot.
I remember first learning of Nagle's algorithm back in the early WoW days in my endless quest to get lower latency for PvP on my neighbor's cracked WEP. I don't really know if it matters much in 2020, but I still habitually run the *.reg file to disable it on every new windows install.
Good stuff, my dad showed this to me as he was working on some home automation and now I'm using it to control the vent fan in my van. I love the ESP8266, it's such a fun little platform and it's very easy to find accessories for them. The little relay board I have was essentially plug and play.
I feel like the value prop would be better if they looked good. I feel like for the purpose of signalling status with ear-accessories Airpods Pro are gonna do a better job these days. It's a neat idea, I maybe you could do something with an industrial or similar piercing and take advantage of vibrating the actual cartilage of the ear? Maybe I just have bad taste but I wouldn't wear these, I hope there's leeway in the design to make something more attractive.
