multi point attractor column grid

Hello, i'm trying to create a structure inspired by Toyo Itos NTU building (http://36.media.tumblr.com/859da8a61e439a8ad62fbf2972700e9f/tumblr_...).

i want my columns to be upper surface and a bottom surface (or points) as seen in the script attached. I am struggling when trying to morph a an object that is not a brep to gain more control.

1) i would like the radiuses of the columns to vary according to the shortest distance between the center of the column to the closest of multiple attractor points (or another system to detemine by hand a few different radiuses for the columns)

2) i would like to control the center of the column, and direct it away from the center of the upper shape, as in the image of Ito's building attached.

3) i would like to divide it to a shigeru ban like construction (is it just offsetting countours or is there a better way?).

thank you,

Adi

I didn't look at your definition but you could look at these discussions :

Hi Laurent,

thank for your fast reply,

please note that the second link you sent leads to a non exsisting page.

The first link did help in making a more elegent script, yet it doesn't allow the variation of radius or the deviation of the column from the center of the upper circle that I was looking for...

Someting like that :

I still didn't look too much to your script. I used mine. Radius is simple. You have n points so you must have n radius, I used randomize but you could put a list of value. You are the artist.

I also made some changes to my script. I could explain a bit more or you are doing the exploration alone.

It would be great if you can explain a bit more, I am struggling...

also- the script it to heavy when I try to put the center points of the columns on a paneling tool "surface domain number", making my computer move to wat slow... is there a mesh alternative for the surface?

Explanations will come. Here is the script with meshes.

Amazing, thank you!

Hi again,

1. I managed to change the veronoi grid to a rectangular one, but when i try to put circles on it- it goes crazy- doesn't recognize which center goes to which point on the circles, and creates too many lines.

2. The randomize parameter is not working for some reason... all the radiuses are the same. I tried changing it to point attractor parameter like I wanted but something is still wrong.

3. Is there a way to slightly shift the columns away from the center of the cell towards an attractor? While remaining vertical?

Thanks again

I will look to it tonight, it could be interesting that you draw a sketch of what you want :

roof shape : many parts (glued) (like Toyo Ito Librairy), one part (like Toyo Ito funerarium)

column shape : profile wanted (one, parametric), how the blending with roof shape ...

because they are many ways to do what you want.

I would like the roof to be composed of seperate parts, the uper profile to be parametric and the bottom just one.

Many thanks.

On ntu squares script :

for point 1, it was just a matter of flatten, data structure is not simple and some changes modify the structures of data. Instead having a list wint "n" elements you get a tree with "n" branches !! So its cures almost everything.

I had a choice for the extraction of points from polygon, it extract by edge or for all the closed polygon. By edge it allows to merge the points of the mesh more easily. I also add some example to change the upper shape of pillars.
