Week 11 [1.06-7.06] Photogrammetric in games


This is an older science, which originated in the middle of the XIX century and fully developed already in the XX
When people got the opportunity to always carry a relatively light camera that can quickly take photos, many began to actively photograph not only other people, but also landscapes. And many experts in many industries have come to the same point.
If people are able to perceive the size, volume and location of various objects in the surrounding world with their own eyes and transfer it all to geographical maps, then why not automate the process of compiling maps using photographs?
Why, for example, not make maps by aerial photography? And then it all happened.




The direction of algorithms that translate landscape photographs into various map formats has begun to actively develop. At the moment, almost all terrain maps are built using these algorithms. People no longer sit and do not draw them manually, but only process multispectral aerial photographs and satellite images.




The most interesting thing happened already at the beginning of the XXI century. Computers became widespread and began to be used for a variety of tasks, digital photography and 3D modeling appeared.
And here, again, so many people thought - why make models manually, if you can transfer them from photos? Not to say that this idea was rapidly developed on the move, but now, after two decades, many game studios already use the achievements in this area.


Sebastian van Elverding, one of the developers of Forza Horizon 3, talks about how photogrammetry was used to create photorealistic textures when developing the game. And he even gives an example of such work on the Unreal Engine 4 engine.



Building models and textures from photographs significantly speeds up game development. Since the creation of models is, at the moment, one of the longest and most resource-intensive stages of creating computer games. And its acceleration will directly affect the budget of the games and the frequency of their release.



But since everything is so good, why are these technologies not used everywhere? The answer, unfortunately, is in the resource intensity of these technologies.

Infinity Ward needed to create an entire stand with 200 cameras and special software, so that it would be possible to form 3D models with a sufficient level of detail. A Microsoft connected to the development of its archives of satellite images of the Earth and the computing power of Azure, which would build a gaming world. Not even all AAA game developers can afford it.




Nevertheless, the creation of textures is, in many ways, based precisely on photogrammetry. And there are many programs for creating models from photographs, including photographs from a smartphone.
Of course, the quality of such models still leaves much to be desired. But, given the speed of development in the industry, in the near future we can expect a significant increase in their quality and wide distribution among game developers.

1. Have you heard or encountered this technology early?
I’ve heard about that technology before, especially during 3D human anatomy model creation, which me and my friends were trying to do a few years ago.
2. Would you like to work with this technology? Or have you tried it already?
I would not. I have my own field of interest which I’m happy with. But maybe one day, something would change in my mind.
3. How do you like the photorealistic texture in the video?
I enjoy the quality of today's videos. It always surprises me how far technology step further.

1. Have you heard or encountered this technology early?

That's what I heard about the technique. Photogrammetry in computer games has been used for a relatively short time. This technique allows us to reproduce, on the basis of many detailed photographs of a given object, its shape, size and position in relation to other objects. Photogrammetry is used by game developers primarily to make the creative process faster. Time gain is very high. It seems to me that this way is characterized by lower labor costs.

2. Would you like to work with this technology? Or have you tried it already?
No. I'm doing another job that has nothing to do with graphics.

3. How do you like the photorealistic texture in the video?

I like it very much, it's hard to tell the difference between this film and reality. Thanks to the combination of this technique with artificial intelligence everyone will be able to create such films or games in real time. Or the games will change in real time and each game will be different.
I've heard about this technology and even saw how it is done; unfortunately I wasn't able to do it myself. It's amazing that we can easily manipulate objects in the computer world, although it is people who created this computer world. Photorealistic textures look great. I really like this technology and this idea for its implementation. As far as I know this technology has already been used in Starw Wars IV in the remastered version. It is amazing how far technology made step in teh futhure.
Yes, it really is an incredible technology that facilitates the process of creating graphics in games or movies. I am glad that this crown is of interest to many :)

I have heard about it in some video or twitch stream, I don't really remember but it was really interesting. It is insane how far we have come with the technology and video games that we play. Few years before it was just pixels and now we can animate actors playing in games! It's just insane! I would like to learn more about this technology and maybe work with some people that know a lot about it. Photorealistic texture is really making you feel what the developers and graphics wanted to show with the game.
1. Have you heard or encountered this technology early?

Yes, I have and I am also a big fan of it. Since 3 dimensional graphics were invented people have been trying to be able to create visuals which couldn't be distinguished from the real pictures. The whole fact that such technology can be used while working on a visual projects is fascinating in my opinion because it enables people to speed up their work drastically.

2. Would you like to work with this technology? Or have you tried it already?

I have been working and experimenting with this technology for some time now and I have to admit that results are not so easy to achieve as it might look at frst but when it finally works out the results are breathtaking.

3. How do you like the photorealistic texture in the video?

Those textures are so nice that is a pleasure just to look at them. They don't have to be necessarly placed on a proper object ot be pleasing for an eye.

1. Have you heard or encountered this technology early?
I haven't heard about it before, but it is very interesting topic.
It's awesome that people can easily create and manipulate objects in the virtual world.
2. Would you like to work with this technology? Or have you tried it already?
No, I have another passion now, but maybe in the future...
3. How do you like the photorealistic texture in the video?
I consider it is on very good level nowadays. Thanks to this kind of high level of photorealistic texture we can feel exactly what was wanted to to show to us.

1. Have you heard or encountered this technology early?
Photogrammetry was a topic of a bachelor’s thesis of one of my colleagues from bachelor studies and his project’s presentation during diploma seminar was the first time when I’ve heard of it. It was super interesting to me, since I’ve never really wondered how maps and this kind of stuff is “made”.

2. Would you like to work with this technology? Or have you tried it already?
Although I seems really interesting, I don’t think it’s my cup of tea.

3. How do you like the photorealistic texture in the video?
It looks really realistic and impressing - simply pleasant to look at.
How do I understand what you mean!
I also like to work on this technology and learn something new every time.
Have you heard or encountered this technology early?
Yes, I have heard about this technology. I have read about it in Internet. It’s amazing. Thanks to today's graphic cards we can generate scenes that looks like real.

2. Would you like to work with this technology? Or have you tried it already?
I’m not a graphics master. I tried to do something in program called Blender. I spent many hours working on model. My work was terrible and very bad. I think this is not for my. I would working on this technology mentioned in article but I don’t have necessary skills for that.

3. How do you like the photorealistic texture in the video?
This textures presented in video looks like very realistic. It’s amazing and fantastic. This will change feeling playing a video game. It’s great.

1. Have you heard or encountered this technology early?
Yes, The Vanishing of Ethan Carted was the first game that I've encountered that was utilizing this technology. Fascinating game, I highly recommend.
2. Would you like to work with this technology? Or have you tried it already?
In terms of gamedev I am more of a code guy, not the artist one.
3. How do you like the photorealistic texture in the video?
I do. Though when it comes to games it highly depends: some titles cannot be imagined in any other form that say pixelart, or sketch drawing. But photogrammetry certainly takes solid place among them.
1. No, I have never heard nor encountered this technology early. This is must be something new.

2. Would I like to work with this technology? I do not think so, because this is not my field, so I never used this technology.

3. I honestly admit that it's impressive. However, before they use it in games, it will take several years, because still common equipment with adequate power, are only for enthusiasts, so it costs a lot of money.
Kgajewska said…
1. No I haven't but your post was intresting and inspiring to know a little bit more a bout this topic! It's so fascinating that we can create sucha a stunning things!

2. I'd love to! Even tho I'm not into high level art nor programming, but I want to know abou this more and maybe try it by myself.

3.Its stunning and impressive. I admire people who can do such a great things.
Jakub Kisiała said…
1. I've heard a little bit.

2. I worker with 3D scanners which are rather designed to smaller objects. I have never work with this tech.

3. I would say that it is only the way of obtain models. I as end-user am not interested in production process, I only care about final products.

1. Have you heard or encountered this technology early?
I have never heard about this technology earlier. Probably I didn’t know the name of it but I have imagined how it works and now I am sure that I was right and finally know the name of it. It looks really great I like the results of this work.

2. Would you like to work with this technology? Or have you tried it already?
I would like to try it, maybe not work with it, because I am not interested in "working" like this. I have never tried it. This technology has changed the way of gaming production, I really admire people who works with it.

3. How do you like the photorealistic texture in the video?
It’s stunning, I enjoy watching this video and somehow I felt satisfied to watch it. It is really cool, especially the time changing on the same natural object.
Wow, this is just awesome!
I am also very excited about the release of a new engine. And I can’t wait to try...

3. How do you like the photorealistic texture in the video?

1. That's what I heard about photogrammetry before.
The photogrammetry technique itself is quite old - Photogrammetry technology is the process of measuring and reproducing shapes using photos. It is used between
others in geodesy. I also use it myself in my research.

2. As I have already mentioned, I successfully use photogrammetry to create a model of the distribution of EEG electrodes (256 electrodes) on the head of the subjects. The photogrammetric station takes a photo of the head with an EEG cap using 11 cameras, then using the software I determine the location and distance of individual electrodes.

However, I haven’t used this technology to create 3D models in games yet:)


3. Photorealistic graphics are most desired by players.
In the games I have heard about, objects created using this method are rather static, still and not very interactive, which is their main downside.
1. Have you heard or encountered this technology early?

Yes, Microsoft Simulator is amazing tool not only in terms of games and the graphics are amazing

2. Would you like to work with this technology? Or have you tried it already?

No and I won't because it not the main subject of my intrest however I now how many passion have people who really work on such a things.

3. How do you like the photorealistic texture in the video?

They are simple amazing, really makes me wow

1. Have you heard or encountered this technology early?
I've heard of usage of this technology in archeology and advanced 3D modelling. I can't wait to see it in upcoming Microsoft Flight Simulator.
2. Would you like to work with this technology? Or have you tried it already?
Unfortunately I haven't used this technology yet. Maybe if my task will require this technology I'll give it a try.
3. How do you like the photorealistic texture in the video?
People are using photographies in texturing for long time, this method is just extension of this practice.

1. Have you heard or encountered this technology early?
Google Maps used to share a tool which allowed to build a 3D model of building basing on aerial photography. I think it is the same technology that is mentioned here. I played with this tools for a while.

2. Would you like to work with this technology? Or have you tried it already?
I am not a computer graphic, but I could try, if there would be some circumstances to do so.

3. How do you like the photorealistic texture in the video?
I like it very much, but to be honest, I was more wondering how one would render someone walking on such a terrain.
Roman Dubovyi said…
1. Of course I did.

2. No, I am not really interested in modeling stuff. Although AI that would help to "dress" the model into photorealistic texture is a good idea.

3. I am glad to see how much we have achieved in only `~20 years.
Grzegorz Rostek said…
1. Yes, i have heard about it, and it's really easy to encounter it these days. I believe it is being used more often nowadays, i think it was used by Capcom in "Resident Evil 2" and "Devil May Cry 5", models in those games look stunning.

2. I tried working with it, but it's hard without knowledge about 3D modelling, since the resault of scans is not perfect and it needs to be worked on.

3. I like it, it really looks just like in real life.
Nowadays technology is so developed that we are able to transfer a realistic object to the game. This technology has been popular in computer games for some time and as a player I can say that it is very much
nice stuff. I have heard a lot about the technology itself but unfortunately I didn't do anything about it. As for the last question, I love how the game is more realistic so I feel more into the game :)
1. My diploma will be partly base on the photogrammetry techniques, so I would even say that I'm an enthusiast! :) From what I've heard, people are usually surprised with this method.

2. It is a little bit frustrating technology. Sometimes you make a hundred photos but when you run the software and after hours of computing it presents you with a strange and wrong model it is truly frustrating.

3. I like both, realistic and simplified graphics. It mostly depends on the project you are working on. I loved the video with an environment with different seasons or even regions. Textures like this tend to have manipulative features, such as the amount of snow or moos on a rock. It is truly amazing what can be achieved in today's graphics.

1. Have you heard or encountered this technology early?

I’ve heard about it when Microsoft announced new Flying Simulator. I must say, I was really impressed by the looks of the game. What’s more, I have a small sentiment to the
previous edition as I used to play it with my father who flied small planes as a young guy.

2. Would you like to work with this technology? Or have you tried it already?

I haven’t tried it and I don’t think I will. Game development is not my cup of tea. I am more into other business areas.

3. How do you like the photorealistic texture in the video?

It’s impressing, of course, how game industry flourished over the years and how advanced games become, but as I said previously, game development and gaming itself is not that I very much enjoy. I treat it more as a form for time passing when I am bored and don’t have anything better to do at that time.
1. Have you heard or encountered this technology early?

Not really but I am not interested in computer graphics.

2. Would you like to work with this technology? Or have you tried it already?

It seems fun but I am not graphic designer or games programmist so I have never tried it and probably never will.

3. How do you like the photorealistic texture in the video?

It looks very realistic. It amazes me that you can "produce" and display something on the computer that looks so realistic. It is sometimes hard to tell if some picture is real or is it just computer graphic. On the other hand graphics are not the most important thing for me in games. I think what matters more is some unique, unusual graphic than photorealistic one cause this one we can find in real life ;)
Rafał Halama said…
1. Have you heard or encountered this technology early?
Yes, as I was studying game development, the teacher has shown us his technology during one lesson. He mentioned same things as you did in your article, it can make process of creating textures faster, but you need a lot of investment in cameras and making photos from every angle possible.

2. Would you like to work with this technology? Or have you tried it already?
Graphic design is not my cup of tea, I'm gonna stick to programming. We were only taught how to make a basic stone texture, so making a photorealistic one would be quite a jump for me.

3. How do you like the photorealistic texture in the video?
I think they look amazing. Photorealistic graphics are the future of games, so I'm glad we're constantly progressing towards them.
1. Have you heard or encountered this technology early?
Yes i did. And even tried to use it.
2. Would you like to work with this technology? Or have you tried it already?
I dont have special techniques, devices and expirience in this industry (if we are talking about photorealistic environment such as - stones, rocks, grass, mountains, ext.) If we are talking about not realistic, stylized things than yes i tried to do it and already did it for my graduate work.
3. How do you like the photorealistic texture in the video?
As i understood the engine in video was Unreal Engine 4, i know that film industry getting rid of "green screen" and make a choice for new backscreens running on Unreal engine 4, for example "The Mandalorian" created using this technology, and even without post processing.

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr
