[Plugin] [CityGen] - Street Generator [WIP] (0.5.2a)

...as long as it remains easy to use, I would say.
Parametric solutions tend to become quite complicated in their attempt to be easy and complete. (e.g Revit...)

Which I why we're keeping it simple for now. We can start looking into more complicated stuff later. And then I'm wondering if it'd be a separate module.

I just updated the OP with a screenshot from 0.5.0 which I'm working on. Added variable street width.
I wonder if there should be an option to Radius: Distance From Corner. That you set the length from the corner where the radius should begin. Question is: what would be the desired default option?

Thomthom:
you asked what default distance from corner? In my city, the ordinances require a minimum setback from corner of 40 feet, or approx 12 meters. I believe there is some confusion here whether this should be measured from the intersection of the centerlines or from the intersection of the edges of the streets.
In practical terms, this minimum distance would not be safe if the streets have higher speed limits for vehicles. The setback distance should be established as a function of time as well as distance. But I digress.
Sincerely,

No, if people preferred to set the radius of the corner (from the edge corner) or to specify the distance away from the edge corner to where the radius will begin.
Currently it simply rounds the edge corner by a given radius.

At the moment this would be up to the user to work out. Calculating the radius by the estimated traffic speed would be an advanced feature for later.
At the moment this is as a simple tool for quick visualisation. Mostly for city area, so you'd just enter the average radius you want.

Chris Fullmer

I agree, simple radius is great.

And I forgot, did we decide that the street generator should create the sidewalks, or is that going to bein the block module? Or de we plan on their being a sidewalk module?

Maybe It wouldn't be bad if Street Generator would automatically assign different corner radius based on width of the roads connecting? Something like (in pseudocode):

if both_roads == 6m
   radius = 4m
elsif road1 == 6m && road2 == 12m
   radius = 5m
else #both roads == 12m
   radius = 6m
end

just an idea..

Chris Fullmer

Thats a good idea! I think it could give some really interesting results

PS - After about 48 hours of straight pain, I think I finally got tortoise to work on Vista 64 bit with Google code - woohoo!!!!!! So we'll look into goole code and compare it with the others. I wouldn't mind one that had a better forum built in and maybe even an IRC channel. But perhaps I'm dreaming? Thanks for the help so far!

Thomthom and Chris:
The way you guys are throwing ideas back and forth-- are we witnessing the first global collaboration on Sketchup plugins or have I missed a bunch of stuff? I say more power to you, and the more collaborators the better for the community. You guys are awesome.

I guess then we'd need some input to approximately it'd be calculated.
Not even sure if the radius depends on the road width? (I'm not trying to make this completely accurate to reality, but a simplified approximation.)

Don't think we agreed. I just threw the question out there.
I think I favour that the module that takes the block and splits it into building footprints does that. Maybe, what the street generator can do is instead of making just the block face, also define the sidewalk face.

Good work Chris.
I still haven't had time to look into the various solutions. (Ben struggling with my website that suddenly went offline. apparently lots of stuff has expired without any prior notification... grumble )

Yes. More collaborators please!
Man, after watching that Google Wave Demo I keep thinking how nice it'd be if that service existed now...

I kind of wish i hadnt seen it now, then i wouldnt keep thinking how good it would be

I think I'm tending to want a separate sidewalk module. It would accept a single face as input and then inset all edges to create the sidewalk. This way it would be easy to make different sidewalk generator modules. So a simple prototype that does an offset can be made quickly, and then others that add scorelines, materials, streetposts, random components, etc, could be added later.

Chris

thomthom

The street module would have to deal with the rounded street corners. If it's doing a blind offset you'll end up with some strangle lines at the corners. I'd think that the offsets would most likely end up having sharp corners. (which I think is better for the parcel generator?)

Chris Fullmer

Hmm, that might require some modeling for me to think through. I am thinking that it should be the sidewalk generators that decides what type of inside corners to make for itself. Perhaps it could be given a face and also the centerlines, or the offset street edges(pre curving) so it could use those if needed to calculate its inside edges.

Again, maybe I need to model it so I can think it through.

Seriously, how have Google managed to swindle us all so we they sit on their arses doing nothing while all you guys work so hard at developing their product for free! Its absolutely insane!

Anyway all I'll say is thanks so much for all your hard work - been said before - but everyone appreciates it!

This thing looks so freakin awesome!

Chris Fullmer

Some of think of it more like "Google made a platform that has 1 million differet users a week using it, and maybe there is a way we can somehow make money off them eventually". So far all my scripts are free, and this is will be opensource, but eventually I'll get good enought to write something and sell it. eventually.

And seriously, doesn't this project look awesome! I'm very excited about it. Thanks for the comments

Most of favourite applications are applications that allows users to develop plugins and extend it as they see fit. Firefox for instance...

interesting,i haven't downloaded it yet but from the pics it looks good.It would suit me for my push/pull cities.Also
i will recommend it on the skyscraperpage forum-google sketchup section as a lot of people there do cities.Usually
they do street plans to show the layout etc.

push/pull city 1-sampadoria

in the above pics there are no road plans,if i had the plugin and put the roads in a different colour
it would have been way cooler.Iwill try street gen and plus make a new push/pull city ...it all so may
be great for faces of skyscrapers....

halroach

Very nice stuff you guys have going on here!
Just a short question:
How did you color the lines in the posted model? Coloring lines is a very useful tool in itself!
Is it something specific to the model? cause I wasn't able to copy and paste the colored lines into another model.

Thank You!

Jim

Hi Halroach (Hal?)

You need to set the Color By Material option for the Sytles. Then you can paint them using the tool.

But I think you make a good point - it isn't particularly easy (for me, anyway) to paint lines. It is sort of hit-and-miss.
