Pixel City - Procedurally generated city

[@iamdivan7368]

This man really was great at videogames in much more ways than one. Rest in Peace, Shamus. Thank you so much for everything you've done

[@vexfidel4127]

I found out about Shamus's passing yesterday. It's taken the better part of a day for me to process it. This was my favourite one of Shamus's projects, and I can't count how many times I fell asleep to this pretty little city wooshing around on the monitor nearby. In the middle of some really rough patches in life, it was comforting. I really should've told him thank-you or something. Thank you, Shamus. At the going down of the sun, in the morning, in light and in word, we will remember you.

[@oxfordeducatedhighschoolhe6989]

Oh wow. I used to watch a lot of his videos and websites on how he would program well over a decade ago. Didn't know he died! That's really sad. Thanks for letting us know. 😥

This is the simplest, yet one of the coolest virtual cities I have ever seen. Now that is an achievement...

[@onlyeyeno]

Oct. 2020 and still very pretty :) In my humble opinion this "city generation" in many ways still beats much that I have seen even now. Especially considering how "automatised" the generation appears and how "lean" the results appears to be. And if it's possible to "generalise" the "algorithms" I could well see this still worth while either as a plugin or a small standalone "city generator" for 3D modeling (and texturing) But realising that this is a more than 10 years old project, I'm well aware that the likelihood of happening is somewhere between zero and none :) Still if You didn't find any other "use" of it, I can report that "at least" it works very well as an "inspirational piece" to show what You can do if You can program.... (as well as You that is). And I actually came here after testing a "WebGL implementation" that credited this "piece" as it's inspiration.. So Yea.. :) Best regards.

[@xCrossBite]

For those people looking for the program! - code.google.com/archive/p/pixelcity/downloads Give this comment a thumbs up so more people can find it, please.

[@firstpersonletsplays1141]

I'm just picturing this kind of thing being used in an open world Rampage-style game, where you control a giant monster causing havoc in city after city to your hearts content.

[@thomasgraham5840]

[@neoaikon]

I love the description, anyone with a basic knowledge of graphics programming should be able to produce similar results. Your results are wonderful! It'd be great for a flight sim, most just have flat textures for "cities".

[@DrunkenDwarfIron]

Dude. I'm beginning to study urban modelling for a PhD. Your program is bloody awesome. Better than many I've seen published in academic journals. Well done!

[@Djungelurban]

Awesome stuff! Totally the way of the future. To hand make every single aspect of every single game is ludicrous, procedural generation is what's gonna have to take over a lot of the time. And this is another very important step towards that.

[@RubberRoss]

Best application I can think of this is for animation. City enviroments can be generally tedious to deal with.

Rest in Peace Shamus. You were an inspiration to us.

[@Nanorobotic]

That's awesome! Nevermind the screen saver, patent or copyright this thing (I dunno which you do for programs) and sell it to game developers. This takes the random level design to a whole new level. Nevermind a randomly generated dungeon, nevermind randomly placed enemies or weapons, imagine a free roaming game that put you in a new city EVERY TIME you played it! It could place new missions and everything at key points, you could save it until you finished that one and have it make a new one!

[@SiliconPrairie]

RIP Shamus Young

[@igotsomespace]

Amazing, had watched this video 8 months ago, spent 30 minutes going through bookmarks to try and find it again. Glad I did. So very inspiring.

[@EvanHowell101]

This is beautiful, the fact that it was 2009 makes it considerably more impressive. Oh Shamus, you shame us!

[@letsdeduce]

Evan Howell Not really more impressive. An algorithm is an algorithm. It will still look good further down the road.

[@Sicaine]

Evan Howell what? We had already Quadcores in 2009. Why would you say something like this?

[@VladStaicu]

Awesome video, Shamus! I just read the entire series and downloaded it as my screensaver. I love your blog and your projects, keep it up.

[@ElMesaMola]

Screensaver? No man, just pure inspiration to gamedevelopers wannabes like me. Glad you shared this. Thanks mate.

[@PixelOutlaw]

Great job with this project! People just don't realize how powerful procedural generation is. If you need a city simply have the computer do the work, things like this save quite a lot of disk space.

[@JPDillon]

Very cool Shamus! Can't wait for the screen saver to be posted. Everyone, go read the project notes on the twentysidedtale site. Very interesting!

[@allthatyousee18]

This is amazing. I'm a first year Computer Science student, and this kind of thing really inspires me. I hope I could do something this cool one day.

[@jaybruce593]

Hi Shamus - "Pixel City" is an incredible piece of work, really well done...

[@Benjuthula]

A superb effort - congratulations. Have you considered variety in the rooftops for helicopter pads, pools, ariels and gardens? Parks, malls and public transport might add to variety in the main streets..and finally historic and outliers would make the cityscape feel more matured and organic. But a fine return on 50 hours, very well done.

[@bnagybalint]

Nice work! You could even play with the arrangement of buildings with difference style and height as higher/newer buildings tend to be built close to each other (like a business district or something). Or you could create a random city grid with short and long streets. But this is a really amazing work!

[@tonyledford5323]

This is a great demo. I like the high level overview steps. I'm learning opengl programming and something like this would be a good goal and I'd learn a lot about textures and stuff. Each step you did was a good next step in the evolution of the model. Your model doesn't really have to be anything, it's just an excellent example of what you can do when you set your mind to something.

[@rne1223]

Amazing how little details makes the whole scene so much better. Thanks for the inspiration.

[@honse246]

going through my old bookmarks and found this and just realizing this is originally why i subscribed to you haha

[@Jugglerman]

Very awesome, can't wait for the demo of this. It looks very realistic (which is kind of scary when you think about it....)

[@davidsirmons]

If you could incorporate this into the Unity engine somehow, you'd likely make a killing. It takes tons of time to make cities by hand, and this procedural method would be a good seller. Believe it.

[@davidsirmons]

Seriously consider making this for Unity. It would be incredibly useful for tons of game efforts.

[@woodchoppers9663]

I could imagine this in a city sim game, where you run a city, but you don't have to bother placing every building, the city build itself up, as you manage it. Or city simulator in a strategy game, where you don't want to spend time on macro management, you go to war or something like that., meanwhile your city grows. Fantastic work Shamus!

@@elbretto6062 it could be a standard douche comment on the interwebs or... or it could be a very cool inside joke, as the buildings here are probably generated using proc gen grammar, so, if you actually used those grammars to cure cancer they would, indeed, be an example of VERY GOOD GRAMMAR! Maybe I try too hard to see the good in people, what do I know :)

[@CosmicD]

this is truely hitting close to my soul. Its a contrast between our abilities and the computer's. NOt to mention that it has a high production efficiency boost and if done with high end quality in mind, could generate entire virtual cities for movies or games. Spore is a game that already endeavors on this. Imagine if something like terragen and pixel city could be used simultaneously to create huge city worlds :)

[@TheRealNici]

This is amazing. I first heard of shamus young when he wrote articles for the escapist, but I didn't know that he was a coder.

[@youmayfindithere]

You've managed to evoke a city very well with the minimum details. Conservation of detail at its finest.

[@VulpisFoxfire]

Beautiful work. What the people complaining about lack of features/detailing and such fail to realize is that this is fundamentally a weekend (well, long weekend anyway. ;-) ) hack to demonstrate the technique, and isn't *meant* to be a fully-fleshed out work. Still...makes you wonder what game programmers keep spending years on, you know? :-)

[@vmg89]

yeah it would be pretty cool to see, I'm still amazed on how much detail there is and made by just 1 guy.

[@jabrilsdev]

great project you have here Shamus! Thanks for uploading it!

[@funmeister]

Impressive. Reminds me of Greeble, only different and really cool in its own way. More than a screensaver, this can be a tool that saves thousands of man hours in game, art and other contextual applications.

[@BOLL7708]

w00t... how funky. I found your channel by the Rage mega-texture reset-button video after searching for more videos of Carmack showing off the Rift prototype. Then as I decided this was interesting I pressed PLAY ZE ALLZ!

It's always a bit odd and fascinating. Thanks for nice videos :D

[@NeilRoy]

Very nicely done! I want to do an outdoor nature style generator, like this, but with all organics, trees, lakes, rivers, Maybe with roads and small towns or ruins. You should make this so it is a world that is of unlimited size, so it generates the world as you travel. Make it so a seed for the RNG can be input and you always see the same world, but it generates it in sections as you travel. Work on an indoor generator so buildings can be explored too. Nice work anyhow!

[@protheu5]

+Helder de Vontaire What sort of game are you talking about? There is no gameplay unless you suggest some. This procedural city is only good as a screensaver or a city for a flight simulator.

[@tribemaster101]

Aidar K An rpg, for instance. Or, pursuing and destroying cars in an arcade style racer. Idk, that's up to the creator.

[@protheu5]

Helder de Vontaire This particular generated city doesn't have any considerable amount of detail for an RPG or a racing game. It looks good only from a distance. You don't want to walk around cubes with blurry textures and moving light sprites.

[@tribemaster101]

Aidar K Well, it's just the base. Obviously you gotta improve it.

[@protheu5]

Helder de Vontaire My point was that you don't build a game around some background, you have a game idea, a gameplay and create a background around it.

[@KlayySOC]

procedurally generated maps for mirror's edge would be awesome :) and yes, I am well aware that it is well beyond the scope of this project, but I thought of it when I read step 7.

[@TripleBarrel06]

Dang this is so good! seems useful for scene fillers in games too. I was watching and wondering why this seemed so familiar, and realised that an Xbox Live Arcade minigame called "Boom Boom Rocket" uses panning through a city just like this, but I think it was Sydney though, because the Opera House was visible in one song.

[@LordMcGray]

Definitely release this as a screensaver, I would love this on my desktop!!

[@Justinbond29]

I was reading his posts as he made this. He actually spent a while making some more complex AI for the cars, but scrapped it because the extra work wasn't really that noticeable, and took too much processing power (not to mention time needed to program proper movement patterns for cars). Some fast-moving sirens would be interesting, but I think he wants more attention paid to the high-up buildings than the street-level details. Still, it'd be cool to see.

[@ColbyCallahan]

This is absolutely amazing! Great work. And thanks so much for sharing.

[@Isiahkan]

Agreed. This would be so cool as a screensaver.

Would add randomly generated advertising panels, displays(dynamic), texts in limited level of height. Another thing: making some logical "landscape" of buildings. There could be random placement of "downtowns" where buldings make hills. But not absolutely random, but slightly growing to the center. And those adwertisings I mentioned before, could become more concentraded in the downtown "hill" then around lower buildings. Make gradients to vertical unwindowed strypes - upward illumination.

[@m1dlguk]
