Grasshopper

algorithmic modeling for Rhino

For my PhD thesis I´m making a connectivity / accesibility test of a certain urban area streets.

i have a problem with the accesibility test, cause i need to know wich points of the grids have direct connections with the others, as the image example

Any idea, to how finally get a list with all the points and their direct accesibility correspondence?????

 

Thanks ¡¡¡¡¡¡¡¡¡¡¡

 

Ps: here are the 3dm & Gh files

thanks!

it`s worked perfectly. thank you very much ¡¡¡¡¡¡¡¡¡¡

if you are studying connectivity, you may also want to check out a great plugin called spiderweb.  we have used it in some urban analysis studies and it's quite handy.

My modest solution.

I dont think yours is correct. For instance, (6) has 4,1,8,2,7. 7 only connects with 0,10, and 6

I started marking numbers from 0, not 1.

i should have opened the file :p
