Recreate a triply periodic minimal surface

[An_Meldung]

Hello alltogether,

I got this picture of a node setup to create triply periodic minimal surfaces (Sustainability | Free Full-Text | The New Boundaries of 3D-Printed Clay Bricks Design: Printability of Complex Internal Geometries) by Sangiorgio et al.

I am not able to find the nodes in the red circle.
Can anybody help me.

Thanks in advance
Cheers

Hi An -

@An_Meldung

I am not able to find the nodes in the red circle.

Those are simply parameters (possibly Breps) with internalized Rhino geometry and named to remember what they contain.
