# parametric urban Grid

Very start of a definition I want to develop here and there for city grid planning. The parameters I wish to incorporate are density, light, courtyards, parks, ect.

My thesis is about " designing neighborhood using
parametric design method , inspired by traditional urban fabrics "
Since i don't have enough information about how to use this method,and
which urban parameters should i use in grasshopper,to design this
neighborhood, i decided to write this message,

i would be so grareful if anyone can help me through this process ,

Thank you so much .

Mona.

How to make this work？parametric urban

Comment by RWNB on March 13, 2012 at 11:08am

hallo danny,

this is not so difficult.
first you need a voroni field.
then you should create several offsets from the V-Cells,
to define:
1 streets, 2 foot paths, 3 land plots 4 and the courtyards.
after that, you should create a surface between the curves,
with that the site was limited.
you should extrude this surfaces in z direction,
to define the hight of the builduings.
you can separatly define the hight of the buildings,
for different areas with attractor and so on..

good luck!

Dear Michael and Mattero...

I have a research project about parametric urbanism... I am collecting all the work in this topic and your work in awesome!!!...

Do you share with us your gh definitions???... or a picture of the definitions, It can be important for our beginner work!!!...

many thanks, I'll try it.

@Michael: thank you very much.

@RWNB: the concept is pretty simple.

I have a flat srf and four attractor points, positioned on the World XY plane (they stay into the srf boundary).

I position a pointgrid by dividing the srf and than evaluate the distance between each point and the four attractors (distances are calculated on the World XY plane).

Then I use a comination of vector sums in order to obtain a single value, that I use to move the point within their Z coordinate.

Finally I regenerate a new srf starting from those points and I slice it with a series of horizontal planes positioned at constant heights. And here we are!

I would like to post the definition but it's quite old. If you are interested let me know and I'll try to convert it into a newer GH version.

Hope that this will be useful.

@Mateo, I have not, but your work is very nice on that one. @ RWNB thanks. @ Nghia The definition starts with a grid o points and deforms the grid via attractors then re connects the points for a new grid. Parameters as you ask are simple. For me I wish them to all be based on attractors. for areas requiring more light have the attractor set deeper setbacks and more open courtyards, population density an attractor can add more dense building in one area then another ect.

nice work, both!

dear matteo, would you explain how you deformed the surface with itse streamlines?

thanks.

Pretty Nice result, Michael!

Have you ever seen this one?

Good work, compliments! :-)

can you show me something about your grasshopper definition?I'm very interested in your work.How do you can bring the parameters such as light,couyard...into grasshopper.thanks so much!
