Facade with different type or size units which are several times basic unit

[steadfast1031]

I have checked several different kinds of subdivision methods, but how to composite of different size of units in one frame like this? Could some offer some ideas?

[laurent_delrieu]

The logic could be to use random reduce first with a rectangular subdivision (classical one), then merging the cells with a logic depending on the height.
When you see this kind of pattern you have to figure out if there is a sort of logic and make the algorithm with some rules.

Algorithm

It is not an easy task, sometimes its better to use your mouse (and brain) and not rely on an algorithm. Algorithm are useful for exploration, optimizations but they are not the answer to all problems.

Do you want to explore many variations or just copycat this building ?

Hi Laurent,

For me, using sketch and mouse to show ideas is an easier way, I did’nt want to copy this building idea to other tower design, I am curious about it and want to know what’s the battery logic behind of the idea. It’s a way to expand the understand of some component compostiion I dont know or ignore.

Commonly, the idea will be retangle filled with uneven or one size unit, in this case, there are several type, yes, it’s not easy.

It is not easy for sure. I have done some subdivision on this forum and old one. This one has some new rules (the height).
I imagine you found the description of this. As you didn’t mention I put it here

It is always good to put sources of images posted. It helps all people interested by your post and also it helps to search on old discussions.

Thanks for reminding, I will pay attention to this.

There is a short description for the glass panels
“Starting from the balconies, glass panels are spreading over the facade following the logic of the diffusion-limited aggregation (DLA). This algorithm simulates an organic growth based on randomly moving particles (in this case glass panels), which aggregate to clusters.”

Did you see what I did some time ago ?

Rectangle false "packing" (Sample and example)

You could use it and then resubdivide depending on the height.

Subdivide given area into randomly sized blocks with no gaps

Visit these topics in the old GH forum and see if they are of some help…

Three size of tiles in a grid

Now exactly what you want, I made that some time ago, it was not so fast but worked. [image] And if you want not the same color touching an edge, you can use my nColor script [image] And for the record I forget this one I did some time ago. I had to change one line of code because it doesnt allowed having just one width ! [image] grid_subdivision.gh (17.1 KB)

Search color patterm on the grid

Hello the idea could be Make an array of empty cell n * m It is possible to add a shape like =>1 cell or 2 cells in column, When you add this shape on free place suppress the possibility to add shape on adjacent cells … redo that until it is OK I made something like this here It was not too difficult to modify the script, without a lot of test.

2D Packing

It is not an answer because I thing it will be better to make a custom program to solve this problem. But here is a way to split the surface. The problem is that it split in too many rectangle, it will be better to use iterative way. Hope it could help. The idea here is to cut using the “walls”. [image] split planar surface.gh (13.7 KB)
