Cheetah, the CONFIGURBANIST

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.

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

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.

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

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!

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 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

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,
