Hi !

I'd recommend to go through all stuff here ( tutorial videos and workflow tutorials ) first, before diving in actual projects :

Concerning the Portland project : There's a way you can get access to it, but you have to request access to the ArcGIS online group named 'ArcGIS for 3D Cities':
http://www.arcgis.com/home/groups.html
Once activated, you can download the CE project of Portland here :

Ok ?

Good news: IE11 supports WebGL and popular library webgl trees.js

andreas.ulmer, I am really sorry for asking you again... but how can I figure out what am i to type in instead of RANDOMPORTNUMBER? If new port number is randomly generated every time, waht is the way to find th current one?

Start CityEngine
Preview a 3ws (double-click on 3ws)
Browser opens, the url shows the random port number

Note: While CityEngine is running, the random port does not change. CityEngine selects one random port when it's started, and this random port is used until CityEngine is closed. When CityEngine is restarted, a new random port is generated.

1. with a custom web server (e.g. IIS, apache)
CityEngine Web Viewer requires a web server to be able to tun. The 2nd part of the description text
"Use CityEngine Web Viewer application on custom web server"
explains how to set up CityEngine Web Viewer on an already installed web server.

2. Use CityEngine built-in web server
CityEngine contains a small web server that is started when CityEngine launches. This is required for the 3ws preview application to be able to run. The url for this needs to start with http://, not with file:// (file:// bypasses the web server).
Note that
* the internal CityEngine web server is started with a random port number that is different everytime CityEngine is started.

To load 3ws files with the CityEngine preview application, place the 3ws in a CityEngine project in your current workspace, and load it with
?3dWebScene=/PROJECT/FOLDER/WEBSCENE.3ws

the complete url looks like

http://localhost:RANDOMPORTNUMBER/ceviewer.html?3dWebScene=/PROJECT/FOLDER/WEBSCENE.3ws

Hi,

what you have seen at UC is not yet available. That was a preview of the upcoming technology. the link at the top of this thread is 'just' the latest version of what's available to the public so far.

ok ? 🙂

Matt,

Brilliant! I have gone through a good portion of the tutorials, but there are even more here, which is fantastic!

I had read that I would need to request access to the group in order to have access to the files, but I guess I thought it would be more like registering, than waiting for approval - which is probably why I couldn't seem to download the CE project. All is well now.

Thanks for your help!

Hey All,

I am completely new to CityEngine (1 week of exploring). I would like to create something like the Portland Zoning Regulations application created for the web viewer - but in my copy of CityEngine. For me this means the easiest way would be to get a hold of the Portland Zoning Regulations files and open them in my copy of CityEngine and tear them apart a little bit - explore how they were made.

Does anyone know if I can get the appropriate files that were used to make this online app?
Thanks!

Hi

true to false got everything working nicely. Thanks for the help.

Llew,

did you modify the dojoConfig flags in the main html file (viewer.html)?
please check that isDebug is set to false in dojoConfig in viewer.html.

<script>
  var dojoConfig = {
 locale: 'en',
    isDebug: false,
    packages: [
      { name: "esri", location: "../../esri" },
      { name: "WebScene", location: "../../WebScene" }
    ]
  };
</script>

Hi

When I try to load Myserver/webviewer/viewer.html, Chrome gives me this error:
GET http://anzgeo3/webviewer/js/dojo/dojo/_firebug/firebug.js 404 (Not Found). See image attached.

When I load http://www.arcgis.com/apps/CEWebViewer/viewer.html I get the ESRI viewer no problems.

Thanks for the help.

Hi Llew

a) what happens when you point to http://myservername/WebViewer/viewer.html ? (without the ?3dWebScene param)
does it show the same as http://www.arcgis.com/apps/CEWebViewer/viewer.html ?
* if yes, application is set up fine.
* if not, please look into chrome error console and post the error output
(Menu - Tools - Javascript console)

if a) works fine
b) please describe in more detail what happens when you point to http://myservername/WebViewer/viewer.html?3dWebScene=../WebScenes/Boston.3ws
* does the loading progress show?
* when does the white screen appear?
on the white screen page, look into chrome error console and post the error output
(Menu - Tools - Javascript console)

Hi
So I then tested the 3ws file again and I am getting progress but still no active page. The page loads in Chrome but all I get is a white screen.

Hi

I had some interesting things happen over night with a server restart. I managed to kill our IIS by registering the 3ws MIME extension for the default site which created a web.config file in the wwwroot folder. This caused the server to throw up an error and none of our web pages would load. I removed the config file and the sites work again.

So I then tested the 3ws file again and I am getting progress but still no active page. The page loads in Chrome but all I get is a white screen.

When I run Fiddler I see an error here: GET /webviewer/js/dojo/dojo/_firebug/firebug.js HTTP/1.1

Hi,

Could you post a snap of the page in which you are getting the error message. are you not even able to see the city engine viewer initial loader ?

LlewCain

Hi Matt

I have installed the CE viewer for my local PC and it works fine. I have done the same installation into the wwwroot folder (following the instructions) for my IIS 6 server and I am not able to view a 3ws file either from localhost or from another pc using machine name or ip address. I have also set the MIME 3ws extension.

I have the latest version of Chrome and I get this error
Server error:
The website encountered an error while retrieving http://MYSERVERNAME/WebViewer/viewer.html?3dWebScene=../WebScenes/Boston.3ws. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this web page later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil the request.

I really would like to be able to share models internal to our network so any assistance will be gratefully received.

Llew

Works fine - Thanks a lot!

Nice! It worked! Thanks a lot!

How much carefully?
My server is IIS 6.

Not too familiar with IIS, but I believe you need to register .3ws as valid file extension.

- In IIS manager,
- either on the webscenes dir or on the whole site
- add extension : .3ws, MIME type: application/octet-stream

How much carefully?
I think i've done all things properly.
I downloaded and unzipped a file, deleted one of them and rename another to 'viewer.html'.
The folders where like this:
/[root of server]
+myCityEngineWebApp
| +webviewer
| +webscenes
| +copy of webviewer [i think that's unnecessary here]
In Mozilla Firefox i go to an address:

http://localhost/myCityEngineWebApp/webviewer/viewer.html?3dWebScene=../webscenes/myWebscene.3ws

and i have an error and scene doesn't show up. Here's my log:

14ms: GL detect: WebGL 1.0 More
15ms: Loading scene file : ./../webscenes/myWebscene.3ws
335ms: Unable to load data Error status 404 on ./../webscenes/myWebscene.3ws?gzipHeader=true

What am i doing wrong?
My server is IIS 6.
