where can be down？

beautiful...

Welcome to the group. At the moment I'm working on a few minor technical issues. I think I will be able to make the whole package available for download within around two weeks. In the meantime, please provide me with your suggestions.

A test edition of Cheetah will be released on Monday September 16. 

any news on the release of that test edition?

Hi everyone. Sorry for the delay. You can download the first version from the link above. Please let us know if you happen to encounter any bugs or other problems. 

Is it working guys? :)

excellent plugin. I am wondering if there is some open source place where I can find those maps (for Istanbul) to be more specific? Or you imagined for user to redraw curves inside rhino? Looking really interesting

Hi, Petar. thanks for your comment. You can use the plugin Elk to use the maps available on OpenStreetMap directly in GH for Cheetah. 

Yes, found it already. Thank you for kind reply

I am still not being able to download the plugin from the below mentioned site.

I need to explore the plugin at the earliest is it possible for someone to mail it to me. you can mail me at nikita.gurav16@gmail.com

Have you tried this link?

Nikita, Please check your email. I sent the files to the address you have posted.

Hello

does anyone knows why this error appears when I open Cheetah in Grasshopper (0.9.0056), with the supplied 3dm example file:

Error (BC30456): 'epsilonequals' is not a member of 'Rhino.Geometry.Line'. (line 160)

or

Error (BC30456): 'epsilonequals' is not a member of 'Rhino.Geometry.Point3d'. (line 233)

It seems not to work for me... :(

Hi, these methods are for sure members of Rhinocommon (the library of methods behind Rhino and most of geometric operations in GH). Based on a similar case, I guess, most probably, you have a Rhino that is not updated recently. You can go to your Rhino settings (the yellow toothed wheel icon) and update your Rhino. 

Hi everyone!

Is this file for plug-in>Cheetah_Pilot_New_Series_Urban_Data_Scope_F

Thanks

Yes. That is the first version of Cheetah as a set of user-object components. 

Hi João Ventura Lopes , 

Did you solve your error problem. Having the same issues!

Hi, 

If you receive these error messages: Error (BC30456): 'epsilonequals' is not a member of 'Rhino.Geometry.Point3d'. (line 233), this is an issue with updating your Rhino 5. You need to go to Rhino/options (the yellow toothed wheel) and check for updates. 

Thanks Pirouz, 

Its working....

Hi Pirouz,

Playing around with Cheetah.

I failed to input a polylines into SplitNetwork direct from Elk, somehow is not making a branches then, and no coloring as Endefekt. So I need to bake it first every time...

What does r ScriptVariable in SplitNetwork? is it percentage of 100 or multiply...?

Second, cant get Block Measures cluster working.Somehow I think (probable nonsense) it does not likes numbers over 1000. 

Can you maybe take a look!

Singapore%20SpaceSyntax.3dm

Elk%20Singapore.gh

PS: Can I take a look inside of clusters :=)

some help?

Hi Igor,

There was an issue with a new Grasshopper I guess. I fixed something and it is working fine now. ElkSingapore_PZN_Ed.gh

Hi Pirouz, 

Thanks for your time... It is working now!

Hi, could you elaborate what is the difference between proximity and vicinity in your definition? As far as I know they mean the same thing.

hi Petar, 

//I found this as nice explanation.

'Vicinity' means 'in the general area of'. For instance: 

"The police were in the vicinity when the bank was being robbed. They arrived before the robber could escape." 
"I was in the vicinity and decided to drop by for a visit. 

'Proximity' refers to the closeness of 2 people or things in relation to each other: 

"He was in close proximity to the figurine when it fell off the shelf." 
"Their proximity to the explosion led the police to believe that they were involved."

Thank you for your kind reply.. Did anyone else have trouble with terrain? When I set it to include terrain in calculation, nothing happens, all calculation disappear.

Also, some explanation could be useful for polycentricDistribution component. What it calculates exactly? And how it is taking into account terrain surface? I would like to know the logic of including terrain surface into calculation, and how it affects results? 

I found a problem with terrain: When terrain is included following outputs report null as outcome: proximity, proxi_col, vicinity, Vici_Color. As a result of that non of the latter procedures is executed. 

Hi there,

can you tell me where i can download cheetah from, all i can acces is a gh file at this link: https://sites.google.com/site/pirouznourian/configurbanist

Cheers!

Cheetah is in that file. Components are designed as clusers

Hi Petar,

In Cheetah, proximity measure indicates how close one is to all points of interest at the same time and vicinity measure indicates how close one is to any of them. For example, you might want to be close to one of the supermarkets (as a point of interest) in your area but you might want to be close to city center and station at the same time.

Cheetah is meant for pedestrian accessibility analyses. Therefore, when you take a topographic terrain into account, all the calculation will be done considering walking impedance. Here you can find a video, in which Pirouz explains more about it.

About your problem with a topographic surface, make sure that:

_ your surface is on top of your network

_your surface is converted to mesh (you can easily do it by using Mesh Brep component)

 _ It is bigger than your network such that it covers the entire network

_there is no intersection between the surface and your network.

I would suggest checking its location on front, right and top views.

Cheers,

Hi Nitya,

We will release the GHA version very soon. At the moment, you can download the GH sample file and save the Cheetah components as user object components. 

Cheers,

Sama

Petar,

About the polycentric distribution component: if there is something to distribute like built space area or anything like that which requires a bounded distribution over network locations, according to some sort of network measures(with Cheetah you have pedestrian accessibility measures available), you may use this component. With this component you can control the spread and shape of a distribution by changing the "p" value and the number of steps. 

Cheers,

Sama

Hi Sama!

Thanks for the reply. How can i save the Cheetah components as user object components? Can you please explain? I am not really a pro at this platform. Moreover, i am attaching screenshots of errors i am experiencing while using the gh file. I think first one is because i am using an old version of grasshopper, i am not really sure about second. Please confirm.

Cheers!

Samane, Thank you for your kind reply. Your explanation and the video you provided made a lot of sense, and it much clearer now. I would only like to ask you what p value stands for in polycentric distribution? I get the effect it has on the calculation, but how would you explain it in terms of real life usage? 

I am also TU Delft student, currently doing MSc 3, and I plan to use your definition of walk-ability and your script (slightly changed and adapted), giving credit to you. If that is ok with you and Pirous

Also, terrain calculation is not working, even after I have checked all suggestions. I am attaching a file so if anyone wants to give it a try.

Rhino and GH file

Strange thing is that your provided example is working, while my is not. I have tried redrawing street network, extending even more terrain, nothing seems to work

Hi  Nitya,

Your grasshopper is very old. Cheetah is not compatible with 0.90014 version.

for saving components as user object components, while one is selected go to File> Create User Object and save it.

Sama

Hi Petar,

Good to hear that the video and explanations were of help. Of course it is alright with Pirouz and me to use Cheetah for your project with proper attribution.

I tried to download your file but the access was denied. Can you attach it again?

Sama

sure.. Desktop.rar

it is a .rar file, I hope this site allows using it...

Maybe to give a heads up, I found that the problem is with the street network, since I have taken your example, applied my terrain and it worked well. Any help would be appreciated 

or rapidshare link http://rapidshare.com/share/E097672A006A9CF26548DB2BAB685523

Samane! thank you so much for guiding me. I'll upgrade my version and come back to you with further queries.

Thanks for being so helpful!

Cheers!

Dear Samane,

I was in a hurry this morning, therefore, I found a way around - I've redrawn all of the streets, and it worked. It doesn't seem to have any troubles with the other issues you've mentioned. 

thank you for your effort and your time, you it is highly appreciated

Dear Petra,

Good to hear that. But in order to make sure you are getting correct outputs, I would suggest to check items numbers 3 and 4 as well.

Good Luck
