> The simulation work is also really impressive -- and a lot of work.
The simulation is from my own micropolisJS (http://micropolisjs.graememcc.co.uk and https://github.com/graememcc/micropolisJS) just stripped of the GPL License headers and attribution.
micropolisJS in turn is a port of Micropolis, the open-source release of Sim City 1989 for One Laptop Per Child.
Edit: edited the link. You'd think I should get links to my own site correct!

My phone is too small -- how many pixels do I need in order for your mJS to render?
looks like lo-th updated the license for you :)
Is that compliant with your license?
I think, when he is the author, than he can decide which licence to use. There are many examples (like MySQL) where double licensing is used. The original author can decide, which licence he finds appropriate.
The author of micropolisJS is not the author of 3D City. In this case, 3D City needs to be licensed under the GPL, and I believe 3D City needs to include the copyright details for the original port.
In addition, micropolisJS has additional terms added to the GPL [0], which are clearly linked to from the top of every source file in micropolisJS [1], which need to be distributed with 3D City.

They're all derived from the original source code of SimCity from Maxis, that I ported to Unix for DUX Software starting in 1991 (see http://art.net/~hopkins/Don/hyperlook/SimCity.README and http://art.net/~hopkins/Don/simcity/simcity-announcement.htm... ), and which was donated by EA to the OLPC project under a modified version of the GPL V3 license, with the condition that the name "SimCity" only be used for versions of the game that have been reviewed and approved by EA QA:

I found your 2D version much easier and more fun to play. Wasted about an hour outright whereas I was over with 3D City in 5 minutes, approximately.
If he is not the same author, then you are right. One statement from an other poster suggested, that he is.
The original author would have the right to add new alternative license conditions as he wishes to.
Maybe the author of 3D City should say something about it.
Edit: Now I saw, what you mean. MicropolisJS seems to be an alteration of the GPL'ed Micropolis of an other author. And the owner of MicropolisJS stripped the GPL license from it to use it in the other project (btw. why?). I am no lawyer, but it really looks to me as a violation of the GPL, at least without permission of the first author.

The author of MicropolisJS is not the author of the ThreeJS SimCity clone that is the top of this HW story.
It's not a clone, it's derived from the original SimCity source code, which EA licensed under GPL V3 with the added condition that it should not be called "SimCity" without EA's approval. So it's important that all versions of the code include that license and the required provisions.

It's his own work. He does not be to be compliant with anything.
It isn't his own work apparently, he copied the simulation and removed the GPL license statement.

It's not the same guy. He does give credit in the README, but still wrongfully stripped out the license information.

It is not necessary, that it is the same guy. When graememcc adds a new license to his own work, than he can do it and an other person can use this license with agreement of the first author.
UPDATE: As much I see now, it seems that graememcc did not consent in using his work with altered license. So it is a violation.

There are three pieces of software. Each software was written by one person.
Micropolis is gpl'd.
MicropolisJS is a version of that, and is also correctly licensed.
3DCity - the submission here - is written by someone else. This person stripped the gpl headers and re-used some code without correctly licensing that code.

lo-th is not graememcc.
All the source code is available, and the previous work is cited, so how is this a violation of the license?
That is not the same person as the one who made the 3D.CITY game.
You should mark up his repository, either add an issue or whatnot, noting that the code is missing your GPL license.

Very neat!
There are small details like laying out roads and making power lines go over them etc that are super-fiddly too.
I know this because I played around with my own simcity for a while, first in true 3D (making curvy roads look nice is damn difficult) and then a 2D grid.
Here's a screenshot I was particularly proud of - the effort to get to that point was more than it looks! http://media.tumblr.com/c9b51ca1eb2b3e89eb8d5af0f560ec34/tum...
More on my algos http://williamedwardscoder.tumblr.com/post/49797579721/willc...
I was going to procedurally produce the buildings using a variation on Eisenscript https://sites.google.com/site/williamedwardscoder/home/exten... with variables in the script based on things like price, distance to other zones, scores etc
I look at the files you link and think "yeah!". I put my city simulation into a Web Worker and the UI in the browser thread though.

The worker code is interesting. Looks like a single observer that watches everything and dispatches to methods on a global state object. One would expect one observer per subject. Is there some implementation detail in web workers that makes this design more efficient than registering an observer per event?
For clarity, by user input it handles the callback of the map being clicked to delegate which tool it's going to use and to update the budget etc... I was excited at first to see all the event handlers setup in a thread that wasn't the UI thread because event handlers are expensive but that doesn't appear to be the case. AFAIK webworkers are fairly isolated so something like setting up event handlers would not be possible.
In Chrome on OS X I find myself clicking to place a zone then having to wait, then move my mouse a tiny bit before the zone would appear. If I started moving the mouse too much after clicking it gets put in the wrong place and if I don't move the mouse the zone never appears.
After 10 minutes I hit a bug where adding more zones seemed to place an 'invisible' zone. Which deleted the trees that were there and could be connected to electricity but didn't draw anything on the ground and would never populate. Or at least I couldn't see if it was populated and I couldn't play anymore.

I've hit that bug a few times. If you save the map, refresh the page, load the map again and bulldoze the invisible zones everything works again.
I'm seeing those "invisibles" in Chrome/Win7, too. It's as if the display engine has run out of sprites. Is there some limited display resource here?
Definitely seems to get buggier with time

The Load and Save worked, the game is amazingly good. The use of "use strict" blew me away, I had no idea that existed, it gives me a sense that JavaScript is becoming a solid language.
The game, day/night, seasons, I would buy this. It might need to be converted to Java to lower CPU usage but even as JavaScript it actually uses less than I'd have thought.
Very nice work.
On "use strict" I can't believe all the stuff JavaScript allows when it's not used, so I'm glad it exists: http://www.w3schools.com/js/js_strict.asp

Really enjoy this! Like everyone else, the nostalgia is so strong.
The only thing that seemed off for me was the "Drag", which I think somebody else mentioned. I found myself clicking and re-clicking it multiple times to pan around the map, which got old after a bit. That was in latest Chrome on Mac OSX.
Great work however!

Awesome! Brings back old memories of late nights and precious cities with the very first simcity.
At this point, my browser has ground to a halt, my retina macbook is running very hot, and the little green rectangle does not follow the cursor anymore to aim where i'm going to plant the next building: https://dl.dropboxusercontent.com/u/14314213/Screen%20Shot%2...

Surprisingly it runs on my Jolla. I thought the browser is not enough bleeding-edge. It's pretty smooth as well, although switching to snow kills it a bit.
I'm really glad to see this wonderful work that people have done based on the original SimCity source code! many thanks to Will Wright and the people at EA/Maxis and OLPC for helping make it open source, and to everyone who worked on making it run so nicely and easily in the web browser. This project shows exactly why that was an important thing to do, and I hope it inspires others to do similar things.
It's nearly killing my whole computer. What are the requirements to run it?
Preferably a WebGL capable browser and video card, otherwise Three.js could potentially switch to HTML5 canvas.
On the newest FF it's very slow (maybe not WebGL?) and on the current Chromium it's not even loading. Both running on a freshly installed Ubuntu 14.04.
Do you have proper drivers for your video card on Ubuntu ?
On my MacBook Air runs smooth on both Chrome and Firefox. Same on Windows 8.1. Unfortunately, I can't test it on Ubuntu because I don't have a GUI installation of Ubuntu (I use the server version).

Runs smoothly on FF on my Macbook (Retina). You likely have a driver issue.
I ran it on Ubuntu 14.04, Google Chrome, nVidia card, it ran great! The CPU usage was a lot lower than I expected for JavaScript doing WebGL.
Butter-smooth on latest Chrome for Mac OS X
does this work? http://get.webgl.org/
what does about://gpu say in Chrome? There are bugs in the latest version of Chrome for Ubuntu in both the Intel and nVidia drivers.

It runs almost as fast as simcity native ran on my 33Mhz 486 in 1991.
Is WebGL evere going to really work?
Is WebGL evere going to really work?
Something tells me your browser doesn't support WebGL, in which case Three.js will default to canvas operations.
This is amazing. I remember playing this game before and it was all choppy. I am not sure it used threejs before. Good job in improving it.
Wow, this is very impressive. Some people say that anything that can be done in a C-type language will be done in JS between five and ten years later -- this is evidence for that point.
The gameplay feels nice, and it reminds me of Caesar II, if that game is familiar to anyone. That being said, I think the game would benefit from introducing a few objectives.

You are right.
About Caesar II/III, it was a nice city building game. But the 3DCity game is very similar to another game called SimCity/SimCity2000. Some mentioned in this thread that it even uses the open source code of the original SimCity 1 for its city simulation code.

It ran pretty well in Chrome for Android.
A few observations about it: The drag view was buggy so I had to re-click it over and over again. It also crashed on me a a couple of times. Also placing objects was hard to do and it took me awhile to figure out how to drag the screen.

What to do to solve the pollution problem? :D
Haven't found anything yet. Concentrating all the industry away from the residential sections doesn't help. Using all nuclear power doesn't help.
Building a lot of parks?
pretty awesome. just wanted to say that in latest chrome on windows 8.1, when the city gets in 30k population range, new buildings and zonings model's don't appear; well, everything new doesn't appear, pretty much. also, wire seems to have trouble being built over steets most of the time
This is beautiful, thank you for posting.
The last 10 min reminded me how much time I spent playing SimCity, SimTower and Civilization.
Didn't work until I reenabled Hardware Acceleration in Chrome settings. Doh!
As a three.js fun, I enjoyed very much. Great job.
Crashes Firefox mobile
Nice! quite fun!
