Grasshopper

algorithmic modeling for Rhino

Hi, I'm new in grasshopper and i'm tryin to make a rectangular grid on a curved surface. Something similar to the image skin. Can anyone help me?

Hmm .... assuming the obvious (i.e. rectangular planar modules, that is)

YAS envelope (rather decorative) was one of the very first designs that ignited the non triangle planar module current trend: these days you start doing things with planar quads (and "up").

It's made with this: http://www.evolute.at/software-en/evolutetools-for-rhino/evolutetoo...

See the classic demohttps://www.youtube.com/watch?v=vGH5yow6vnY

Good news: On the other hand Daniel Picker (a very smart fella) has developed tools in Kangaroo2 (the most WOW plug-in that GH has to offer) that allow a very effective quad planarization (100%).

Bad news: this is rather a task that requires a certain experience. If you are new to GH ... I would strongly recommend to postpone similar adventures ( if you have real-life/pragmatic aspirations out of these planar quads). 

BTW: planarity Plan C : http://shapeop.org/

you can download the dll and the C# examples ... but "components" used are not ...er ... GH components: they are C# code using the ShapeOp.dll

But K2 would be my recommendation:

On the foreground: (top) the classic ShapeOp sample (red means non planar) (bottom) one planarization result (green means planar yellow means ... well ... "almost").

On the background: Daniel's sci-fi stuff yielding 100% planarity (1020 mesh faces).

That said (real-life) a 100% planar quad ... well ... you need some quite special aluminum frame system capable to deal with construction tolerances (glass panels don't like much "deviations" he he). One of the reasons that YAS panels are arranged that way (the other is natural ventilation).

 

And this is K2 doing the sci-fi thing.

I hear The Voice:

Avoid answering to that thread AT ANY COST (because if we proceed [not a good idea]... it could yield (*) far more questions than you Imagine) but is like Karma: the worst ... the better.

(*) read the comments related with the brep thingy.

Note: Yas is replaced with YAZ (Z for Plan Z).

Note: Load Rhino file first.

Note: Go after some other thing before it's too late, he he.

Moral: the worms are free.

And here's the (usual) update.

Notice the colossal difference in computing time just by slightly altering the threshold AND tolerance values.(Multi Threading is OFF, mind).

Why may you ask? well ... for an engineer zero tolerance is The anathema (there's no such thing in real-life, even NASA works ... er ... with "higher" values, he he). So zero for aluminum panels that will be made somewhere by someone ... makes absolutely no sense.

That said I do hope that you know how to deal with that K2 engine (when to start, when to stop etc etc).

Hi Peter, first of all thanks for your time. I've read that the yas hotel was made with Evolute as you said. i'm going to try all the information you send me.. I'm just interested in geting the structure by now. i made a first aproximation, but getiing an irregular modulation. i'm gonna try your definitions.

Well ... you should always have the broad picture in mind. By that I mean that exploiting ways to make a Yas type of envelope  ... is meaningless IF you don't have a clear approach related with the big thing (planarity).

Because (in most engineering cases) is the end of the path that outlines the start.
