Hi Psygorn
These designs are so interesting, especially the box with 7 leaves. I wish I could understand the math behind it! :)
This is the tutorial I studied to get the process of making it.

After several trial and error, I managed to make these nodes. (Attached)
The anchor point for the first node is on the corner of the leaf. (According to the tutorial. Max 6 leaves)

I played a bit with different anchor point positions on next 3 nodes.
In these nodes, leaf number can be set to a higher number, But I'm guessing they are not 3d print friendly?
I think moving the anchor point to the outside of the leaf is the key to have more leaves,
But where is the most efficient position for anchor point?

Hi MO (MO_TE),

Wooow! I am stunned by your nodes! :-) (I need time to study them carefully though!)

Yes, it seems it is the most robust tutorial on making Iris Dome Boxes out there (and it was mentioned by Brian here: https://moi3d.com/forum/index.php?webtag=MOI&msg=10641.6) , However, I did not study it (I think I should study it
at some point)

Is it possible to rotate the leaves using your nodes? (I did not study your nodes carefully as of yet!) if the leaves do not bump into each other then surely u can make it 3D-printable! According to my personal experience the most two important things for making an Iris Dome Box are: 1- determining the shape of the leaves 2- determining the Anchor point around which a leaf can rotate without bumping into other leaves! the rest is easy!

Once again u showed how powerful Nodes are! and what crazy things one can do with Nodes + conventional modeling! Thank u (and of course Max) for that.

> I think moving the anchor point to the outside of the leaf is the key to have more leaves,

Indeed this trick is used to make the 6-leaf IDB (Iris Dome Box). ;-)

Sorry, I don't have the answer for this question as of yet!

>> Is it possible to rotate the leaves using your nodes?
Yes, Change the "Aperture" value. Also, use the other blue nodes as well. E.g "Leaves", "Height"

Hi MO,

I did use Aperture but it seems the leaves are rotated around the center, I mean they are not rotated around a pivot point on the lateral side of the sphere! ( I hope this explanation is good)

However, the way leaves rotate using your nodes is another type of movement which is interesting in its own rights! :-) And I can tell u it is possible to make a 3D printable design with such movement.

Hi
>> it seems the leaves are rotated around the center
I guess you are using the "Iris_Box_3" node. I used the center point as anchor point there.

But you can see the anchor point in other nodes shown by a little cylinder.

>> it is possible to make a 3D printable design with such movement.
Cool! :)
It can handle up to 60 leaves!

Hi,

> But you can see the anchor point in other nodes shown by a little cylinder.

Yes, I saw it. :-) in "Iris_Box_4 node" it seems it works fine! (Or at least I am sure with your Nodes one can make as many Iris_Dome_Box designs as he/she wants) great job! :-)

>It can handle up to 60 leaves!

Let's make that one! :D

>> Let's make that one! :D

35 Leaves :)

Isn't it satisfying?

:-)
