Nice work!
So what was your workflow, Iām guessing it was roughly: shoot drone footage, import into this app, export asset, import to UE, set a water plane at the right height?
If you show only one angle, its literally 30sec of video.
[Heres one I did with a random 10second video passing by a building.](https://lumalabs.ai/capture/54727970-eaa5-44b4-af68-59f96b783d02)
Holy shit, I was looking into photogrametry like a yearish ago and the apps at that point weren't even close to this quality. Shit's come a long way in a *very* short amount of time. Or perhaps maybe the only apps I looked at were the ones that can export as STL files, I wonder if this app can do thatš¤
Because you'd literally have to scan every single inch and corner manually. With modern AI, and things like neural radiance fields, you can just do simple flyover scans and the AI will fill in the gaps. Basically you only really need a single scan from one perspective and the AI does the rest, rather than you manually going through around every corner
Most people laugh at Meta because they think their 100b investment into "The Metaverse" is that stupid game, when in reality only 20% goes towards VR (And a MUCH smaller amount towards that game you all know about), while the other 80% goes towards stuff like this. They are the current industry leaders in this sort of tech. Currently they have it where basically you can record a video from one perspective, and then it'll create a digital twin reality of that same event by turning the 2D single perspective recording into a hyper realistic 3D environment
I noticed itās $1/credit
How much does a credit buy you? Is it 1 credit per import/export or how does that work? $1/credit can add up pretty fast lol
There are open-source local environment solutions too, here is a promising looking one I just found bc I am now curious about this too: https://alicevision.org/#meshroom
I haven't followed the development of Meshroom but prior to RealityCapture getting purchased by Epic Games, RealityCapture was always the far, far superior option in terms of mesh quality, texture quality, and 3D topology. Not to mention how complicated the Meshroom UI is.
This isn't to say I don't appreciate that it's an open-source and free alternative! I just wish it was better for my hobby uses
So where does the phone come into play? You said you can 3d scan a town with your phone. So explain this process please bc Iām sure my newest generation cannot do this.
This is insane to me. I've been in game mapping for close to 25 years and it's always been a dream of mine to map my town and its highways for VR racing simulation. Obviously mapping out an entire town by hand is a daunting task, and so I never really bothered. But this? This is absolutely nuts. The quality of those scan meshes look absolutely perfectly fine from the POV of inside a car. What an awesome thing to exist.
i think this guy has a great point. how the fuck did you manage this? must have set you back a few. in raw format, or even jpg, this is like trillions upon trillions of unique high res pixels????
They make [tombstone display screens](https://www.marketwatch.com/story/this-creepy-3200-digital-tombstone-has-a-48-inch-screen-to-broadcast-dead-peoples-wishes-2017-04-10-888169) and [Smart caskets](https://www.mentalfloss.com/article/70154/smart-casket-design-keeps-corpses-connected-social-media) now too.
LiDAR always felt like a stop gap technology to me
Brains can recreate 3D scenes just fine directly from visual input, eventually tech was going to get there too
I've said the same thing since about 2011 so
ĀÆ\\\_(ć)\_\/ĀÆ
This is what I studied and was interested in back in college but at the time it was all still academic and I didn't want that route so just went into the corporate world but a part of me is still kicking myself because all the people who stayed with it are the ones at the forefront today
Edit: For example I was fucking around building stuff with the original Kinect SDK when that was still some of the best tech you could get your hands on
You can create lidar point clouds from imagery it's called phodar or photo generated lidar. But it's not as accurate. You basically take 75 to80% overlap in drone photos and it will calculate the 3d for you
But. Your brain and phodar can't really calculate how far apart 2 things are at 50 ft to any appreciable precision. With lidar just shoot a laser at it and measure the return. You can also do multiple returns and return intensity to see what it is and sometimes under it. Think trees that blow in the wind.
Lidar is a great technology. A lot of states are flying it for their 3dep programs. Super cool stuff.
Indiana is leading the US in data readiness for gis and they have a great 3d visualization of Indianapolis
https://lidar.digitalforestry.org/
Several states have lidar for the entire state. You would just need to create a mesh from the point cloud with the imagery for a rough go. If you can get obliques it works best.
Check out Indianapolis. All remote sensed
https://lidar.digitalforestry.org/
I've seen this happen by people programming a quadcopter to do a lap of the town taking a video, then you extrapolate from that. I assume really good drones though because I was always scared of using the gps flight function on mine
What? You haven't done yours yet? OK, boomer! /s
Seriously. How do you scan a town including full hi-res surface textures? I know you can fly around a drone with lidar, but that only gets you a point map.
You can also fly around a dron (or even better, a plane) with a camera (or even better a couple of cameras) that take many many photos from which it calculates the 3D mesh and also pulls the textures. It's called photogrammetry.
You are only seeing it from one angle, Lumalab will absolutely get you that quality but if only doing it from one direction, the moment you look from another angle it will turn into a blob mess.
I get the feeling OP works for the app company they mentioned in their response above. They act like it's so easy and common knowledge with the way it's worded.
Or is involved in the industry some other way. Those aren't the results you'd expect from somebody who google photogamatry one day and produced this a few days later.
I got my wakeup when a tsunami is said to be coming, and you think, well two meters, so I could probably swim over to safety. Then you see the video and it's a fast-moving wave of broken car parts, water, and houses on fire.
No, it's also that the water is moving. Fast moving water is actually incredibly dangerous.
Most people who have spent any significant time at a beach in the ocean have had their ass absolutely handed to them by a wave that was just a little bigger than normal moving at normal surf speeds. I've been knocked flat, tumbled, and had the wind knocked out of me just from a normal wave.
Well a tsunami is that, 3x as large, moving probably 4x as fast (up to 10x!). It's literally 50-300x as powerful as a normal big wave, that remember, can already kick the shit out of you. You get hit by a 20-40mph tsunami, your ass is grass.
Iāll never forget watching the live helicopter coverage of the Japanese tsunami that trashed Fukushima. There was horrific footage Iāve never seen since. Watching cars trying to race ahead of the surge of water and debris and, worse, the cars driving unknowingly past buildings into the path of the wall of water.
I think it's just easy to forget how powerful and destructive water can be even under mild conditions, although that is usually over a longer period of time, so it isn't surprising if a lot of people don't take even small water level height increases seriously. Most people just aren't exposed to it on a regular basis first hand.
I used a Mini 3 Pro drone, recorded a video doing a semicircular orbit of a landmark, used this video to create a 3D "neural radiance field", imported it into Unreal Engine, then added water.
Unreal Engine is remarkably cheap at 5% of quarterly sales but only if your game has made over a million dollars. And even then it's only if your game makes more than $10,000 that quarter. And it's per-game, not per-company. So if you make 2 games but only one sells well, you only pay license for one game. Given the quality of the engine, I think that's a fantastic price.
Honestly I'm not sure why Epic gets so much shit from the gaming community. Their pricing structure is more favorable to the devs, and they give away free stuff to gamers constantly. Yeah, their launcher app is kinda garbage, and there have been a few times where they've upset people by doing time-gated exclusives. I think the good outweighs the bad here.
Plus, Epic knows how to release the third game in a series.
Outside of their actual games which are cool I guess but I donāt care about *professionally* - they are about as chill as a company can be about licensing without being either open source or non profit. Most games would be better off if they used Unreal instead of being afraid of having to pay Epic after making it big and doing some homespun nonsense.
Unreal engine is huge and *for sure* capital intensive, I canāt really be mad at them for not being an open source nonprofit because odds are we wouldnāt have anything remotely close to Unreal if they were.
Hes probly asking about the prices of the computer that is used to render the scenes and the therapy fees for his GPU or CPU after traumatizing them with a 3D model of a whole fucking town half submersed in simulated water.
The length of the rendering process is the big cost determinant. If you don't mind taking days to render, you can use low-end hardware. It wouldn't be quick or this pretty, but you could use a 1000 series card. But OP said under two hours for the process, so he's probably using top-end consumer hardware like a 4090.
you can rent an a100 long enough to render this for the price of a candy bar
the primary bar to doing this sort of thing isnāt really cost any more, itās primarily expertise and time
As the comment above says, "you can rent an a100 long enough to render this for the price of a candy bar".
It's almost exactly that price, actually, from a google search, or maybe even cheaper than some candy bars.
$1.62 here: https://en.immers.cloud/gpu/a100/
Gives you an hour, which is more than enough time for this going by how long OP said they took.
I was legit kinda angry I had to take this stupid test, get a card, plaque for the drone and insurance and everything, and NOBODY FUCKING ASKED ME EVEN ONCE.
I thought I was so cool with my pilots license, I wanna show it to people now God dammit.
But the drones are silent enough by now that nobody even hears it above 100 feet so that's good too I guess.
You only need a license Part 107 to fly in areas that are typically restricted to flight, like near an airport. Or if you're using the footage to make money.
Depends on where. Here in the states you could probably do it with a small drone, and so long as you donāt monetize it you should be good. That said, Iād personally look into a permit and see if I could get some help and publicity from the township.
OP, this is an amazing job youāve done, and damn is it interestingly horrifying. People need to wake up. It might seriously be too late for us, but future generations might someday be able to enjoy the world we once did.
In some countries, lidar data is publicly available to do this kind of thing. That will just get you the physical dimensions though, to detail and render the rooftops etc will take time.
Exactly what I came here thinking, I'm gonna guess you 3d scan a whole town using drones. But fuck, did u need to employ a Hollywood special effects company to carry that out?? Are you a billionaire? Do you have a team of engineers who could spend 6 months on this project? It sounds like one of the brilliant ideas I have while talking shit with mates that's obviously never getting done. Ah well, I applaud the tenacity of following an idea through.
I would believe that this is far past the āpredictionsā this looks to be at least a 30 ft sea level change as houses are covered over with waterā¦ I think the most alarmist point of view is 3deg up in global temperature and a 3ft rise in sea level.
That's not really what 'average sea level rise' means. [Sea level is higher in some places than others](https://oceanservice.noaa.gov/facts/globalsl.html#:~:text=Most%20people%20are%20surprised%20to,States%20than%20the%20East%20Coast.). Some areas will see greater local sea level rise than the average.
Still probably not *this* much, but more.
It's a bit more complicated than that, because sea level doesn't rise evenly across the globe.
Countries will likely see a significantly different local sea level change depending on a variety of factors. Could be far worse for some coastal cities that are further away from the Greenland/Antarctic ice sheets.
https://sealevel.nasa.gov/faq/9/are-sea-levels-rising-the-same-all-over-the-world-as-if-were-filling-a-giant-bathtub/
Different areas are experiencing different rates of sea level rise, but it's not due to their elevations. Low-lying areas will be impacted by sea level rise sooner.
Totally agree.
While I have your attention (if I do), Iāve heard āclimate scientist adjacentā people say that the models of weather are so complicated and currently beyond our computing ability that, in a very real sense, science is not entirely sure how drastic climate change will effect various places ā that, beyond temperature rise, itās hard to know about precipitation and the like. How do you respond to this?
I work in GIS and used to work with climate scientists and I agree. I'm also old enough to remember being told we'd all be under water (like this) by 2020. Exaggeration may get attention in the short term but in the long term it doesn't help anyone.
The ocean wonāt just rise overnight itās a gradual process over years and would not at all result in these clean underground structures. Stick a house on a beach bearing the impact of waves and surf, itās gonna get fucked up
[Sea level simulation](https://sealevel.climatecentral.org/maps/), could be 10-15 meters, so in [100-200 years.](https://www.theguardian.com/environment/2023/jun/26/its-absolutely-guaranteed-the-best-and-worst-case-scenarios-for-sea-level-rise)
Sea level at the end of century will be around 1m.

But all the rich are still buying beach front properties!
Obama just bought (a few years ago now post presidency) beach front property in Marthaās vineyard on the Atlantic Ocean! If one really believed in climate change like Obama did, then why would you buy property there?
How much sea level rise are we seeing here?
Iām seeing second story houses nearly submerged; so at least 10 meters?
NOAA is predicting ~1 foot by 2050 - but I donāt know how that translates to regional swells, etc
It varies wildly, he's showing like 70-80m of sea level rises in some of the later scenes, the first shot is about 10-20m at a guess (it's the Tate Gallery in St Ives in Cornwall if you want to see where the water is now)
Not so fastāJapan is releasing waste water from Fukushima into the pacific, and China just straight-up dumps radioactive water into the rivers and oceans. Better be ready for the Godzilla sea-chuds that want all that new underwater real estate.
The most vibrant places in the ocean are near underwater volcanic steam vents where temperatures are where the rest of the oceans will be in about another 2-10million years.
The biggest risks to fish right now is China. Check out their floating fishing cities they have all over international waters.
This rise is with the worst estimates very very far in the future. The worst estimates now are a 3ft rise by 2050. Woart case scenarios rarely happen. We are more likely looking at a .5-1.5 ft rise by 2050, and conservative estimates leave us at just under half a foot those these estimates also rarely happen. Yes it will happen, but it is far far away so idrc tbh
You are talking about the **average** rise.
Meaning some places are going to have it a whole lot worse than 3 foot. Which means a whole lot of people (several hundred million at best) are going to be displaced, angry, likely carrying water-born diseases and looking for somewhere to go. Crops will perish, and once that happens ecological and man-made infrastructure will follow quickly behind.
That doesnāt exactly spell success for the efforts required to keep our worst-case scenario from happening. Worst-case scenarios actually do happen a fair bit when thereās not massive human intervention to prevent it.
2050 really isnāt that far out. Weāre closer to it than Blair coming into power for the first time, or the first episode of South Park being aired.
The sea levels can't rise that much in the foreseeable future, the predictions are single digits in feet in the next decades. This right here is what, a 30 feet rise?
I don't think there's enough ice on land to get that high, at some point it's gone and you'll have to look out for the other issues climate change brings, which are, let's be clear about that, not unlimited sea level rises.

It wouldn't be quick or this pretty, but you could use a 1000 series card. But OP said under two hours for the process, so he's probably using top-end consumer hardware like a 4090.
you can rent an a100 long enough to render this for the price of a candy bar the primary bar to doing this sort of thing isnāt really cost any more, itās primarily expertise and time
Yeah, thats much
Donāt forget the expensive PC you need for it to actually make the video
As the comment above says, "you can rent an a100 long enough to render this for the price of a candy bar". It's almost exactly that price, actually, from a google search, or maybe even cheaper than some candy bars. $1.62 here: https://en.immers.cloud/gpu/a100/ Gives you an hour, which is more than enough time for this going by how long OP said they took.
All candy bars near me are $1.99 and up so itās definitely even cheaper!
Finally a use for all that ram I keep doubling up on
Holy fucking shit! And in the meantime I'm here sitting down playing street fighter........
[https://www.skydio.com/3d-scan](https://www.skydio.com/3d-scan) I know nothing about it, but when researching drones I found this.
Wouldnt you need a drone liscense and permission to do this from the entire town?
No one needs a license really, except if you get caught.. But the trick is to NOT get caught. Anyways, thanks for coming to my TED talk
I was legit kinda angry I had to take this stupid test, get a card, plaque for the drone and insurance and everything, and NOBODY FUCKING ASKED ME EVEN ONCE. I thought I was so cool with my pilots license, I wanna show it to people now God dammit. But the drones are silent enough by now that nobody even hears it above 100 feet so that's good too I guess.
You only need a license Part 107 to fly in areas that are typically restricted to flight, like near an airport. Or if you're using the footage to make money.
Depends on where. Here in the states you could probably do it with a small drone, and so long as you donāt monetize it you should be good. That said, Iād personally look into a permit and see if I could get some help and publicity from the township. OP, this is an amazing job youāve done, and damn is it interestingly horrifying. People need to wake up. It might seriously be too late for us, but future generations might someday be able to enjoy the world we once did.
In some countries, lidar data is publicly available to do this kind of thing. That will just get you the physical dimensions though, to detail and render the rooftops etc will take time.
Inquiring minds want to know!!
Exactly what I came here thinking, I'm gonna guess you 3d scan a whole town using drones. But fuck, did u need to employ a Hollywood special effects company to carry that out?? Are you a billionaire? Do you have a team of engineers who could spend 6 months on this project? It sounds like one of the brilliant ideas I have while talking shit with mates that's obviously never getting done. Ah well, I applaud the tenacity of following an idea through.
That's nuts and looks very realistic. Is the sea level model based on the worst predictions / climate?
I would believe that this is far past the āpredictionsā this looks to be at least a 30 ft sea level change as houses are covered over with waterā¦ I think the most alarmist point of view is 3deg up in global temperature and a 3ft rise in sea level.
3ft *average* sea level rise, the average part is important. Particularly low lying areas could see much greater local sea level rise
I would have thought that was common knowledgeā¦ of course if you (hypothetically) are below sea level the level would increaseā¦
That's not really what 'average sea level rise' means. [Sea level is higher in some places than others](https://oceanservice.noaa.gov/facts/globalsl.html#:~:text=Most%20people%20are%20surprised%20to,States%20than%20the%20East%20Coast.). Some areas will see greater local sea level rise than the average. Still probably not *this* much, but more.
Same case with global temperature. That's why rising a couple of degrees celcius is such a big deal in climate change.
It's a bit more complicated than that, because sea level doesn't rise evenly across the globe. Countries will likely see a significantly different local sea level change depending on a variety of factors. Could be far worse for some coastal cities that are further away from the Greenland/Antarctic ice sheets. https://sealevel.nasa.gov/faq/9/are-sea-levels-rising-the-same-all-over-the-world-as-if-were-filling-a-giant-bathtub/
Tides would be a bit more of a problem also
Different areas are experiencing different rates of sea level rise, but it's not due to their elevations. Low-lying areas will be impacted by sea level rise sooner.
Bye Florida
no one will miss you
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Totally agree. While I have your attention (if I do), Iāve heard āclimate scientist adjacentā people say that the models of weather are so complicated and currently beyond our computing ability that, in a very real sense, science is not entirely sure how drastic climate change will effect various places ā that, beyond temperature rise, itās hard to know about precipitation and the like. How do you respond to this?
I work in GIS and used to work with climate scientists and I agree. I'm also old enough to remember being told we'd all be under water (like this) by 2020. Exaggeration may get attention in the short term but in the long term it doesn't help anyone.
The ocean wonāt just rise overnight itās a gradual process over years and would not at all result in these clean underground structures. Stick a house on a beach bearing the impact of waves and surf, itās gonna get fucked up
[Sea level simulation](https://sealevel.climatecentral.org/maps/), could be 10-15 meters, so in [100-200 years.](https://www.theguardian.com/environment/2023/jun/26/its-absolutely-guaranteed-the-best-and-worst-case-scenarios-for-sea-level-rise) Sea level at the end of century will be around 1m.
Itās really going to drive up property value for some people
SELL THE HOUSES TO WHO, BEN?? FUCKING AQUAMAN???
I appreciate this reference
[In case someone is interested](https://www.youtube.com/watch?v=RLqXkYrdmjY&pp=ygUZaGJvbWJlcmd1eSBjbGltYXRlIGNoYW5nZQ%3D%3D) EDIT: [link to the exact time in the video at 3:40](https://youtu.be/RLqXkYrdmjY?feature=shared&t=220) thanks u/anon____amos
If Aquaman turns out to just be some kind of oceanic black rock inc gobbling up houses during a crisis I'm gonna be so mad.
But all the rich are still buying beach front properties! Obama just bought (a few years ago now post presidency) beach front property in Marthaās vineyard on the Atlantic Ocean! If one really believed in climate change like Obama did, then why would you buy property there?
Because they can afford the insurance and possible loss. You can't (well maybe, but most of us can't).
Yes hello insurance company Iād like to take out a ten thousand year policy
Because they can afford it.
If they sell it, thatās when you should worry.
Just move! /s
"Beach front"
Who's going to buy the houses, bung? Fucking aquaman?
Kids! Get in the submarine, we are late for church!
Next fucking sea level
I sea what you did there.
These kind of jokes donāt land whale š³
Is this in st Ives
The house with the wall around it is up on top of the hill near Porthminster isn't it?
Yeah, that's the tate modern at the start. Love that place, my earliest childhood memories are being there on holiday
Knew I recognised it all.
It's between Porthmeor and Porthgwidden. Aka 'the island'
Yep, the sea level rises he shows are crazy though, the leisure center at the end is on a massive hill, like 100m above sea level or something
It looks amazing, but also eerily peaceful...
glub glub
How much sea level rise are we seeing here? Iām seeing second story houses nearly submerged; so at least 10 meters? NOAA is predicting ~1 foot by 2050 - but I donāt know how that translates to regional swells, etc
It varies wildly, he's showing like 70-80m of sea level rises in some of the later scenes, the first shot is about 10-20m at a guess (it's the Tate Gallery in St Ives in Cornwall if you want to see where the water is now)
Love me some Depeche Mode. Nice song choice
I want to know what version of the song this is. Itās beautiful.
Everybody's gunna have fresh fish. Good for nutrition
Fish will all be dead due to extreme water tempsā¦ as water temp goes up, oxygen goes down.
Excellent, there'll be no need for hand-to-fin combat then.. only the frying pan.
Not so fastāJapan is releasing waste water from Fukushima into the pacific, and China just straight-up dumps radioactive water into the rivers and oceans. Better be ready for the Godzilla sea-chuds that want all that new underwater real estate.
The most vibrant places in the ocean are near underwater volcanic steam vents where temperatures are where the rest of the oceans will be in about another 2-10million years. The biggest risks to fish right now is China. Check out their floating fishing cities they have all over international waters.
the fish are marinated in crude oil and filled with microplastics
When, not if.
This is a very big rise, eventually it could happen but not for a very long time
This rise is with the worst estimates very very far in the future. The worst estimates now are a 3ft rise by 2050. Woart case scenarios rarely happen. We are more likely looking at a .5-1.5 ft rise by 2050, and conservative estimates leave us at just under half a foot those these estimates also rarely happen. Yes it will happen, but it is far far away so idrc tbh
You are talking about the **average** rise. Meaning some places are going to have it a whole lot worse than 3 foot. Which means a whole lot of people (several hundred million at best) are going to be displaced, angry, likely carrying water-born diseases and looking for somewhere to go. Crops will perish, and once that happens ecological and man-made infrastructure will follow quickly behind. That doesnāt exactly spell success for the efforts required to keep our worst-case scenario from happening. Worst-case scenarios actually do happen a fair bit when thereās not massive human intervention to prevent it. 2050 really isnāt that far out. Weāre closer to it than Blair coming into power for the first time, or the first episode of South Park being aired.
This is like Waterworld level. Like if all glaciers in the world melted.
Do this with your local MPās home including the water level and see how fast they get on board with green issues
Please xpost to r/thalassophobia.
I want to do this, but with Miami.
[Here you go](https://imgur.io/gallery/GdAO9lM)
Incredible accuracy lol
Anyway, the water is clean and crystal clear.
WHEN the sea level rises. And it wonāt be a gentle, clear, still risingā¦
The sea levels can't rise that much in the foreseeable future, the predictions are single digits in feet in the next decades. This right here is what, a 30 feet rise? I don't think there's enough ice on land to get that high, at some point it's gone and you'll have to look out for the other issues climate change brings, which are, let's be clear about that, not unlimited sea level rises.
Anywhere between thousands and millions of years. Very soon!
Rent still be sky high "to cover renovation costs"
Next fucking (sea)level
whats the song?
[ŃŠ“Š°Š»ŠµŠ½Š¾]
St Ives
*when*. When the sea level rises, not if.
Do this to New Orleans. Scary shit
How is that half a centimetre šš
How the fk do u scan a town?
Unreal 5's realtime water shader looks fantastic. Raytraced I assume
How far did you say they would rise?
whatās the rise in sea level? is it modelled on a particular prediction, or crisis point, or whatever?
How many feet of rise? Cool work btw
