facade_honeycomb_panelling help pls

Salut,

I modelled a facade with T-splines. now I want to put a structure over it, as a new cover. Preferable honeycomb, else if possible or maybe easier a voronoi, a diagrid or anything nice. I don't understand that kind of workflow how to handle this surfaces. I guess I need to do it with mesh + weaverbird.

In the attached files you can see my try. I transformed the t-splines surface into nurb-surfaces and I joined the small parts manually to get bigger parts. Then I mapped a honeycomb structure over it. But it is inaccurate and it takes a lot of time, ...
And if possible, how could it be done, that the structure is mostly equal, mean, that the for example honeycomb elements have mostly the same dimensions?

What would you propose for handling this issue?

-panneling it?
-packing surface?
-anything else?

Any Help is appreciated!!

Thanks in advance,

Sebastian

Voronoi isnt too hard:

Now for honeycomb or anything regular, thats another story. Facing the same problem here.

hi systemiq,

can you explain how the upper left component is called ?

ah, ok!

it is called "freeform cloud"

oh you already found it, ok! :)

hey, thx for the fast reply!

wow, yep, it don't seems to be that hard! I enmeshed myself in a much more complicated way, ... Aaah nice! :)
Hmm right now, for given the cover a thickness, is it better to scale the voronoi cells and extrude or loft them or use the fillet option? I attached your def.

Get an inner shell (offset should work) join and cap inner and outer shell, boolean difference each voronoi volume with shell, you will get correct volumes.

If you need only "flat" objects, scale cells, and perhaps project on brep, loft.

You can also work with only curves from intersection 3dVor/Inner+outer Shells + scales/moves.

http://www.grasshopper3d.com/video/medellin1-1 was made this way (except it was a mapping).

Thanks again for your reply! I tried to solve the thickness problem but I can not handle it, sry! It is difficult for me to understand your approach. The video you linked looks nice and it is the direction I want to go to too! Aaah shame on me, you give me three possibilities and I still don't get it, ... my offset try looks like a mess:

it doesn't work for me. Maybe you can give me some more advise?! I would really appreciate it!

Thanks!

Did you offset the surfaces from the t-splines object? And did it look like a correct output? I cant really see much from your screenshot.

Well, I offseted the object but it seems not to be correct, see attached image. the voronoi grid is displaced. Maybe I also misunderstood it but,... uff no idea :(
