00:00:00.080 --> 00:00:07.040
the occipital structure sensor it's a mobile 3d sensor that allows you to

00:00:04.400 --> 00:00:11.599
capture dense geometry and high fidelity 3d models very quickly it has a mode

00:00:09.760 --> 00:00:16.720
that allows you to capture an entire room at once and it even lets you play

00:00:14.320 --> 00:00:20.880
with some augmented reality games stay tuned for more of that and hit the like

00:00:18.640 --> 00:00:32.079
button down below if you want to see us check out more 3d printers in the future

00:00:32.079 --> 00:00:37.360
vote for turnip we always say it on the WAN Show buy the shirt it's in the link

00:00:35.280 --> 00:00:42.079
in the description down below so why the structure sensor well i've

00:00:39.840 --> 00:00:46.239
been really interested in 3d scanners and printers for quite some time now but

00:00:44.719 --> 00:00:49.840
usually the best option is like shapeways or whatever and it's kind of

00:00:47.920 --> 00:00:54.480
been under that whole too expensive and not really good enough for mainstream or

00:00:51.520 --> 00:00:58.480
me yet category yes i know i'm a virtual reality nut but one or two vr dev kits

00:00:56.800 --> 00:01:02.800
is nowhere near the cost of a truly awesome 3d scanning and printing setup

00:01:00.640 --> 00:01:06.159
let alone the cost of plastics the structure sensor stood out to me however

00:01:04.559 --> 00:01:11.200
and i decided that it's time to start getting my hands dirty in the scanning

00:01:08.400 --> 00:01:15.600
and printing space unlike most 3d scanners the structure sensor isn't a

00:01:13.040 --> 00:01:20.320
contained unit with a spinning platform or a moving camera or whatever instead

00:01:17.759 --> 00:01:25.280
it just drops your ipad air 1 or 2 ipad mini 2 or 3 or 4th gen ipad then plugs

00:01:23.680 --> 00:01:30.080
in through a lightning connector to the ipad itself and the internal battery of

00:01:27.600 --> 00:01:35.520
the structure sensor is charged through power from your mains not the expected

00:01:32.960 --> 00:01:40.000
micro usb solution it's a depth sensor using an invisible laser projected

00:01:37.439 --> 00:01:44.320
infrared blast an infrared camera to capture and then in conjunction with the

00:01:42.320 --> 00:01:48.880
ipad's accelerometer gyroscope and compass it can map out a relatively

00:01:46.560 --> 00:01:54.000
accurate depth map that can be put together into a point cloud and finally

00:01:51.840 --> 00:01:58.399
modeled if that's what you want these movement-based mechanics really give you

00:01:56.320 --> 00:02:02.719
the freedom to scan some very interesting objects that you may not be

00:02:00.240 --> 00:02:06.719
able to put into a contained type scanning unit

00:02:04.240 --> 00:02:11.039
maybe the material's shape or actually just the material could be the problem

00:02:08.640 --> 00:02:14.879
imagine scanning a sand castle for most people this wouldn't be very possible

00:02:12.640 --> 00:02:18.080
due to picking up said sand castle and having it fall apart on the way to the

00:02:16.400 --> 00:02:22.959
scanner but if you were able to bring the scanner to the sand castle

00:02:20.879 --> 00:02:28.080
then you got a different story so 3d scanning mapping entire rooms playing

00:02:25.680 --> 00:02:32.319
augmented reality games and maybe some more how well does it do it all let's

00:02:30.400 --> 00:02:36.879
find out so this is just the object scanner and you can use your thumbs to

00:02:34.000 --> 00:02:39.840
resize how large the box is you don't want it to be too small

00:02:38.160 --> 00:02:44.319
because then i'll end up chopping off part of poor terran's head

00:02:42.720 --> 00:02:48.400
and you don't want it to be too large because then i'll pick up stuff like the

00:02:45.840 --> 00:02:52.319
chairs and the desks so i'm gonna guess it's around here i'll get some of his

00:02:50.239 --> 00:02:55.920
shoulders in there and as you can see it'll put kind of this

00:02:54.160 --> 00:03:00.160
this white stuff on top of whatever

00:02:58.160 --> 00:03:04.560
it has in the scan whatever data you'll get you can notice already that it seems

00:03:02.560 --> 00:03:09.680
to be doing a pretty good job but i don't have taran's glasses in here it

00:03:07.440 --> 00:03:14.159
doesn't pick up glasses very well because it's clear and the ir light

00:03:12.080 --> 00:03:16.800
isn't going to kind of come back to the sensor very well off of something that's

00:03:15.920 --> 00:03:23.599
clear when it goes red like that i'm too close so i need to kind of come back

00:03:20.640 --> 00:03:26.080
so i just moved too quickly you might be able to see this on the

00:03:24.879 --> 00:03:30.159
scanner it says recovering move gently just

00:03:28.400 --> 00:03:34.159
trying to patch in some various holes that we have it's coming

00:03:32.319 --> 00:03:38.159
along quite nicely actually so i'm going to press stop

00:03:36.080 --> 00:03:41.680
it's not that bad really there's i'm it's there's something there's there's

00:03:39.440 --> 00:03:45.760
holes here yeah there's holes there color view

00:03:43.440 --> 00:03:49.200
there's your it actually did pretty okay with the

00:03:47.040 --> 00:03:53.120
glasses a lot better than i expected one thing that i want to clarify before we

00:03:50.560 --> 00:03:57.120
do room scanning is that it's kind of designed for an empty room it's not

00:03:55.680 --> 00:04:02.879
designed for a super crazy clutter really small room

00:04:00.080 --> 00:04:06.720
like this so i'm putting it into a worst case scenario and we'll see how it works

00:04:04.879 --> 00:04:09.519
and here we go you'll see it's kind of fun you kind of put everything in the

00:04:08.720 --> 00:04:16.799
room into like tron almost

00:04:13.280 --> 00:04:18.720
i'm gonna let it look at the inside

00:04:16.799 --> 00:04:21.280
so that it can see that those are closet doors

00:04:20.239 --> 00:04:25.919
whoa that looks funky i think i moved too

00:04:23.759 --> 00:04:29.919
much and it tore wow so it thinks that closet is just insane

00:04:28.800 --> 00:04:36.240
all right let's try this again i'm going to try to move less i'm going to try to

00:04:32.240 --> 00:04:36.240
not move my position like at all

00:04:38.000 --> 00:04:44.240
all right so you can see how much of a better job it did there when it's given

00:04:41.759 --> 00:04:48.400
something a little bit more simple it even did a much better job of the closet

00:04:46.639 --> 00:04:52.000
it still has a bit more depth than it probably actually has

00:04:50.479 --> 00:04:54.960
i don't know that's that's pretty accurate actually now we can try whole

00:04:53.840 --> 00:04:59.360
filling that makes it even a little bit better

00:04:57.120 --> 00:05:03.120
that definitely did fix some areas the roof fan looks kind of insane on x-ray

00:05:02.000 --> 00:05:08.320
view raw cool now let's try the last one

00:05:06.240 --> 00:05:11.520
augmented reality so i get this little cat

00:05:09.280 --> 00:05:16.000
and balls fall down and i have to try to go get them but because i scanned these

00:05:13.919 --> 00:05:20.320
objects in the cat can't go through the mineral oil

00:05:18.479 --> 00:05:24.560
bottle as you can see right there cannot go through the mineral oil bottle

00:05:21.759 --> 00:05:28.320
but i can go around it it's a rather simple game but this is

00:05:26.560 --> 00:05:33.120
basically a dev kit so you can go in here hack the game up

00:05:30.720 --> 00:05:36.000
make whatever you kind of want and maybe make something a little bit more

00:05:34.639 --> 00:05:40.240
fun than cat chase's ball around bottles of

00:05:38.639 --> 00:05:44.800
mineral oil so that was fun but what about a

00:05:42.240 --> 00:05:48.960
conclusion the structure sensor is cool and it's definitely fun but how

00:05:46.880 --> 00:05:53.440
practical was it well that actually depends a lot on the operator and the

00:05:51.039 --> 00:05:57.919
subject things that reflect or absorb a crazy amount may actually cause you some

00:05:55.680 --> 00:06:02.880
problems and a shaky inexperienced or impatient operator will result in issues

00:06:01.280 --> 00:06:06.560
the fact that the platform isn't the same all the time will leave you needing

00:06:04.400 --> 00:06:10.720
to edit many of your scans in relatively minor or sometimes relatively major ways

00:06:09.199 --> 00:06:14.400
would i recommend it yes if you need a freeform scanner for

00:06:13.039 --> 00:06:20.800
many applications that it could be needed for instead of a contained scanner yes if you have want to have a

00:06:17.919 --> 00:06:25.120
ton of fun with it not necessarily if you're looking for the highest potential

00:06:22.800 --> 00:06:27.759
scanning resolution and fidelity in the end

00:06:26.160 --> 00:06:31.759
speaking of things dollar shave club dollar shave

00:06:30.080 --> 00:06:36.160
club is a great way to get razors and other bathroom supplies shipped directly

00:06:33.919 --> 00:06:40.479
to your door for only a few bucks a month the razors are high quality and we

00:06:38.400 --> 00:06:44.800
have a ton of community members who use them every day and love the smooth shave

00:06:42.639 --> 00:06:48.880
that they get no matter how thick or coarse their facial hair may be for some

00:06:47.360 --> 00:06:52.720
reason this comes as a shock to many people out there but yes

00:06:50.479 --> 00:06:56.240
even though i have facial hair i do shave and i would definitely say that i

00:06:54.720 --> 00:06:59.360
get a better shave from dollar shave club razors than those old ones that i

00:06:58.560 --> 00:07:05.199
had the razors are pretty darn nice and on top of that the razors also come with dr

00:07:03.360 --> 00:07:09.280
carver's shave butter which goes on smooth so you can see what you're doing

00:07:07.680 --> 00:07:13.199
and they're peppermint scented butt wipes for men for those of you over here

00:07:11.599 --> 00:07:16.319
in north america that can't get your hands on a bidet
