[CityGen] City generator

Edson

CityGen guys,

would CityGen be able to create streets and buildings over a hilly terrain? or would it be restricted to plane surfaces?

remus

For the moment id guess it will only work on a plane (thoms script only works on a plane, and the code i was messing about with at the beginning of this thread only works on a plane) as coding stuff to work on hilly terrain is exponentially more difficult. It is certainly something to look at in the future, though.

You could create the layout above the terrain and use the Sandbox tools to drape the streets ?

The street generator I'm working on at the moment only works planar. The extra third dimension makes things a bit more complicated - I'd like to make it work in a simple 2D manner first. I expect to mature it a bit in 2D before I take on 3D.

Not sure what the others got planned.

And Drop to place the buildings..?

Something like that has to be done by the user until we can get it working in 3D.

wow, this whole project is very exciting! I like the idea of the plugin doing all the work
no, but seriously. it would be great if the user can input all the information he likes and the plugin adds all the other information automatically (or parametrically).

so if you only have three main roads and lets say five important places of a city, the plugin will fill in all the other information (either by default or by user set parametres). thus the user can influence the outcome of the model to whatever level he likes.

the CityGen project is one of those big things that make SketchUp and the SCF so tremendously exciting!
I am really looking forward to first results

Hi Thom.-

here is me again, now back in Spain. I'd tested city generator and found some bugs in the use. I don't Know if it's due to the configuration (as I told you before) or is a real bug in the programming.

I'm using Skechup 7.1 with many plugins instaled and here the main bug I found:

I can't modify the parameters on "define streets", can't create news types or change the predef-values

best regards

After I installed city_gen.rb and street add-ons, all my ruby scripts died:
see my discussion thread here:

I think maybe there is something up with SU7.1

thomthom

That's very odd. Never seen that before.
Did you install anything else as well?
Where did you place the files for CityGen and StreetBuilder?

ibr_remote

The way I had them organised was like this:

..\Plugins\street_gen.rb
..\Plugins\Street_Gen\webdialog\ etc etc
..\Plugins\modules\readme.txt

That's what I extracted from my SU7.1, and these are now kept in a temporary folder.

I'd really like to use this script, so it would be great if I could figure out to do.

ibr_remote

I removed all my scripts other than city_gen.rb and put in all those of city_gen.rb and related.

I get this error when launching SU7.1

%(#0000FF)[Error Loading File street_gen.rb
undefined method `file_loaded?' for main:Object]

Ah. This is probably why.

Modules to CityGen, such as StreetGen, should be located under the module folder you find the the CityGen folder.

It is mentioned in the instructions, but I know it's not necessarily obvious. On the StreetGen page it's mentioned in the small prints under the download. On the CityGen page is described under "Core and Installation Check".
This whole project is very much work in progress (except that there has been little progress the last year) - so all our instructions are not that obvious to follow. We where talking about installers, but the project fell down from out priorities before we got to that point.

So, what I think you need to do is remove all the CityGen and StreetGen files you added to your plugins folder.
Then see if your other plugins work.
If they do work, then first install CityGen core
Then install StreetGen to the modules folder of CityGen.
