Is there a reason why, at some angles of rotation, you can see straight through lots of holes?
As if there’s some alignment happening.

it looks like the shape is based on sine functions which simply perpetuates everything orthogonally in xyz directions

You can fit a periodic packing of infinite rods very well in the spaces either side of the gyroid surface. These channels show up as clear views through.
(Actually the view channels are larger than the rods in the weaving, since they are allowed to intersect with others in the other directions)

I dont remember clear, sorry…(maybe)

1)Yes, totally, that came out of the algorithm.
I should open it and see in detail, because it is so…
but if you see the minimum surfaces (image) you can also easily see that pattern in some way sometimes orthogonal in some sense.(““symmetry””, think i !)
2)but i think that i was not happy with the time-computer,
and i have open Meshmixer, to perforate there.
( really, i need to see the gh file again ).

I don’t know if it was so desired but it was.
(I’ll tell you the truth, it’s been days since that exercise, and I don’t remember clear-everything,
but I’m still quite reading the tutorials on ParametricHouse.com.

There you find the right answer.
For me a highly recommended site.

The channels in the gyroid run not just in the orthogonal directions, but also in the 4 tetrahedral directions

There are so many wonderful things to explore about the gyroid. Alan Schoen, the guy who first discovered it is still around and has this amazing page about its history

Thanks
Nice page to read about it.
I save it

This reminds me of this: Unveiling the Future of Antennas and RF Lenses using Radix™ 3D printable material! - YouTube

They were making RF lenses and the shapes looked similar. Is this just coincidence or does the geometry or minimal surface help in some way? Perhaps filling space with minimal material and being 3D printer friendly.

I looked through your linked page for references to microwaves or RF lenses but didn’t see any. But it was a long page so I might have missed something.

Careful: the YouTube link is full of dirty RF talk.

For example, “Colby explained that as the volume of the solid sample is known, the reduction in center frequency of the resonant, plus the Q factor change can be used to characterize the relative permittivity and loss tangent of the material.”

And there’s worse, the description of the Fabry Perot Open Resonator is practically pornographic: Unveiling the Future of Antennas and RF Lenses using Radix™ 3D printable material! - YouTube :slight_smile:
