trifoil knot

Hi everybody,

I'm studying this shape. Karl is fantastic:

I'm almost at the end but I need just a little to finish.

Do you have suggestions, please?

Thanks.

Gianni

after days ... I tought there was 2 curves, I scaled, turned, shift the second but nothing. Then I realize it's a trefoil node with one curve that rounds 2 times. I used the minimal surface plugin ... but nothing. Please, help me, I don't sleep well any more :)

Carlo (http://www.grasshopper3d.com/profile/CarloBeltracchi) you are here can give me any idea?

Thanks

Hey Igor,
which plugin are you using? I have the Lunchbox stuff installed but it seems that something is missing or am I wrong?

cheers,
Sebastian

It is a bug of my computer. After saving the definition it became "Unnamed". On the picture missing MinSurf

tool from Extra tab.

Ah ok, but I don't have the MinSurf component, I guess you added it to the EXTRA tab by yourself. Where did you get it from or did you wrote it on your own? Thanks for your help.

I believe it is Robert Cervellione's miminal surface generator.

Hi Igor, Sebastian and Chris, thanks for your answer.

The shortcut to obtain the shape is use "sculpture generator"

http://www.cs.berkeley.edu/~sequin/GEN/Sculpture%20Generator/

But I'm trying to built it only in gh. Talking about your definition, Igor, just a thing. I've commected you definition to the moebius and I must say that the shape is quite similar but why it reduce it's width till zero each 120°.

Thanks a lot

You'll find as attachment the shape I generated with sculpture generator.
