Microsofts brand-new Flight Simulator is a technological marvel that sets a brand-new requirement for the genre. To recreate a world that feels alive and genuine and includes billions of structures all in the ideal spots, Microsoft and Asobo Studios relied on the work of several partners.
Ahead of the launch of the brand-new Flight Simulator, we sat down with Blackshark co-founder and CEO Michael Putz to talk about dealing with Microsoft and the businesss broader vision.
One of those is the small Austrian start-up Blackshark.ai from Graz that, with a group of just about 50 individuals, recreated every city and town worldwide with the aid of AI and massive computing resources in the cloud.

Point clouds, which arent being used in Flight Simulator, are another location Blackshark is concentrating on today. Point clouds are very difficult to check out for human beings, especially once you get extremely close. Blackshark uses its AI systems to analyze point clouds to learn how lots of stories a building has.
Labeling, however, is still something the team has to do just to train the design, whichs really an area where Blackshark has made a lot of development, though Putz would not state too much about it since its part of the companys secret sauce and among the primary factors why it can do all of this with practically 50 people.

Something Blackshark is extremely open about is that its system will make errors– and if you buy Flight Simulator, you will see that there are apparent errors in how some of the structures are put. Indeed, Putz told me that he thinks one of the hardest difficulties in the task was to persuade the companys advancement partners and Microsoft to let them utilize this technique.

” Data labels had actually not been a top priority for our partners,” he stated. And generally, if the information expert wants to discover a ship, he tells the discovering algorithm what the ship is and then he gets immediate output of spotted ships in a sample image.”
Bongfish gone back to this idea when it worked on World of Tanks, simply due to the fact that of how lengthy it is to develop such a substantial map where every rock is placed by hand.
” Our larger vision is a near-real-time digital twin of our planet, particularly the planets surface, which opens a trillion use cases where traditional photogrammetry like a Google Earth or what Apple Maps is doing is not helping because those are just streamlined for pictures clued on simple geometrical structures. For this we have our cycle where we have been drawing out intelligence from aerial information, which may be 2D images, however it also might be 3Dpoint counts, which are currently doing another job. And then we are envisioning the semantics.”
With time, that system will also enhance, and since Microsoft streams a great deal of the information to the game from Azure, users will certainly see changes in time.
From there, the analyst can then train the algorithm to get back at much better at discovering a particular things like a ship, in this example, or a shopping center in Flight Simulator. Other geospatial analysis companies tend to focus on particular niches, Putz likewise kept in mind, while the companys tools are agnostic to the type of content being analyzed.
” Machine learning takes a slightly different road,” kept in mind Putz. “It also looks at the shadow, we believe– because its a black box, we do not really know what its doing.
” The entire business was founded on the concept that we require to have a huge advantage in innovation in order to get there, and specifically originating from video games, where big productions like in Assassins Creed or GTA are now hitting capability limits by having thousands of individuals dealing with it, which is extremely difficult to scale, really difficult to handle over continents and into a prompt delivered product. For us, it was clear that there need to be more semi-automated or automatic steps in order to do that.”
Bing Maps photogrammetry data only yielded precise 1:1 reproductions of 400 cities– for the huge majority of the world, though, that information doesnt exist. Microsoft and Asobo Studios needed a system for building the rest.
” By random possibility, I satisfied somebody from Microsoft who was trying to find a studio to assist them out on the new Flight Simulator. The core concept of the new Flight Simulator simulator was to utilize Bing Maps as a playing field, as a map, as a background,” Putz discussed.
Blackshark utilizes its AI systems to evaluate point clouds to find out how lots of stories a structure has.
” What we do generally in Flight Simulator is we look at locations, 2D locations and then discovering out footprints of buildings, which is actually a computer vision task,” stated Putz. “But if a building is blocked by a shadow of a tree, we actually need machine knowing because then its not clear any longer what is part of the structure and what is not since of the overlap of the shadow– but then machine knowing finishes the staying part of the structure. To determine the height of a building based on a shadow, you require the time of day, though, and the Bing Maps images arent actually timestamped. It may be that 20% of the buildings are off– and it actually is the case I think in the Flight Simulator– however theres no other way to tackle this challenge because contracting out to hand-model 1.5 billion structures is, just from a logistical level and also budget plan level, not workable.”
Based upon this experience, Bongfish started developing an internal AI team. That group utilized a variety of machine-learning strategies to develop a system that might gain from how designers construct maps and after that, eventually, build its own AI-created maps. The group actually ended up utilizing this for a few of its tasks before Microsoft came into the photo.

” For me, having been in the games industry for a very long time, its so motivating to see, due to the fact that when you develop video games, you know how groundbreaking the technology is compared to other industries,” stated Putz. “And when you look at simulators, from military simulators or commercial simulators, they always sort of appearance like shit compared to what we have in driving video games. And the time has actually come that the game technologies are spreading out of the game stack and helping all those other markets. I think Blackshark is among those examples for making this possible.”
Those semantics, which describe the building in really accurate detail, have one significant advantage over photogrammetry: Shadow and light information is essentially baked into the images, making it difficult to relight a scene reasonably. Given that Blackshark knows everything about that constructing it is building, it can then likewise position windows and lights in those structures, which develops the remarkably sensible night scenes in Flight Simulator.
And after that, if the system understands that the average height of a shopping center in an offered area is normally three floors, it can work with that.
” What we do generally in Flight Simulator is we take a look at locations, 2D locations and after that learning footprints of structures, which is really a computer vision job,” stated Putz. “But if a building is obstructed by a shadow of a tree, we in fact require artificial intelligence due to the fact that then its unclear any longer what belongs to the building and what is not due to the fact that of the overlap of the shadow– but then machine knowing completes the staying part of the building. Thats a super basic example.”
Blackshark is really a spin-off of video game studio Bongfish, the maker of World of Tanks: Frontline, Motocross Madness and the Stoked snowboarding video game series. As Putz informed me, it was in fact Stoked that set the business en route to what would end up being Blackshark.
And thats where Blacksharks bigger vision is available in. Due to the fact that while the business is now getting honor for its work with Microsoft, Blackshark also works with other companies around reconstructing city scenes for self-governing driving simulations.
The apparent next problem is finding out the height of a structure. If there is existing GIS data, then that issue is easy to fix, but for a lot of areas of the world, that data just does not exist or isnt readily offered. For those locations, the group takes the 2D image and tries to find tips in the image, like shadows. To identify the height of a building based on a shadow, you need the time of day, though, and the Bing Maps images arent in fact timestamped. For other use cases the company is working on, Blackshark has that which makes things a lot much easier. Whichs where artificial intelligence is available in once again.
And though Blackshark discovered its start in the gaming field– and while it is working on this with Microsoft and Asobo Studios– its really not concentrated on video gaming however rather on things like autonomous driving and geographical analysis. Putz noted that another excellent example for this is Unreal Engine, which started as a video game engine and is now everywhere.
” So it was simple for us to fill positions like a PhD in rooftop restoration,” Putz said. “I didnt even understand this existed, but this was exactly what we required– and we found two of them.
While Blackshark was able to depend on some other data, too, consisting of photos, sensing unit information and existing map data, it has to make a determination about the height of the structure and some of its qualities based upon very little information.
” Its simple to see why reconstructing a 3D structure from a 2D map would be hard. Even determining a buildings specific summary isnt simple.
Now, while Putz states he fulfilled the Microsoft group by opportunity, theres a bit more to this. Back in the day, there was a Bing Maps group in Graz, which developed the first cameras and 3D variations of Bing Maps. And while Google Maps won the market, Bing Maps really beat Google with its 3D maps. Microsoft then introduced a research center in Graz and when that closed, Amazon and others came in to buy the local talent.
” One of the first video games we performed in 2007 was a snowboarding video game called Stoked and S Stoked Bigger Edition, which was one of the first games having a complete 360-degree mountain where you might use a helicopter to fly around and drop out, land everywhere and go down,” he described. “The mountain itself was procedurally constructed and explained– and likewise the positioning of barriers of plant life, of other snowboarders and small animals had been done procedurally. We went more into the racing, shooting, driving genre, however we still had this concept of positional positioning and descriptions in the back of our minds.”
” Youre talking 1.5 billion buildings. At these numbers, you can refrain from doing standard Q&An any longer. And the conventional finger-pointing in like a level of Halo or something where you state this pixel is not excellent, fix it, does not actually work if you establish on an analytical basis like you do with AI. It may be that 20% of the buildings are off– and it in fact is the case I think in the Flight Simulator– however theres no other way to tackle this obstacle since contracting out to hand-model 1.5 billion buildings is, just from a logistical level and also spending plan level, not manageable.”
This is where Blackshark comes in. For Flight Simulator, the studio reconstructed 1.5 billion structures from 2D satellite images.
