The geometry of tissue cell differs from cell to cell as they are similar to each other in sequence and structure. I have found in softwares that the design of the geometry depends on the shape of the node and the profile which represented as a curve of the sine (sinus), where a curve is drawn, as well as the section of the node, which is most often in the form of a circle or an oval. ..., then, we deploy the node on the curve to obtain a special section, then we generate several curves for the first node of the same direction. Then we repeat the procedure for the nodes or curves, and this time these curves are perpendicular to the first curve. Until we get what we call Tissue weave 3D. The process can be repeated horizontally to obtain a grid, as shown in the attached images. Is it possible to help for the design of a 3D Tissue weave with the geometry nodes technique. enter image description here

    These weaves could certainly could be constructed, using Geometry Nodes, but before deciding that's the way to go, you could have a look at the shipped add-on Tissue Tools , a large part of which is specifically built for this purpose. – Robin Betts Feb 05 '23 at 12:49

    The last knitting version use something you can use https://blender.stackexchange.com/a/282530/2214 – vklidu Feb 05 '23 at 14:06
  • Do you mean Tissue addon, for these case of a flat tissue as shown in the figures I do not know how to adjus it well. – saded Feb 05 '23 at 18:03
  • Thank you vklidu, I have already seen this page, but here it is the case of a fabric on a tube, in addition the adjustment of the section of the tissue is a difficult one. – saded Feb 05 '23 at 18:06
  • This Addon is included in the code 3DMax: http://www.scriptspot.com/3ds-max/scripts/weave-mesh – saded Feb 05 '23 at 18:15

Based on Bezier Segment ... with the first Transform > Scale > Z you can change waviness ...

Simple Array ...

When connected to Group Input node for simpler manipulation ... enter image description here

  • Good vklidu?, How to make the nodes in contact? – saded Feb 05 '23 at 21:14
  • What do you mean by nodes in contact? – vklidu Feb 05 '23 at 21:28
  • Amazing, thank you vklidu, thé contact IS between tube profil. For the 3rd figure or the figure named "d", can we generate it with this technique, (See figure 1 for this paper: https://link.springer.com/article/10.1007/s10853-019-04096-1 ). – saded Feb 05 '23 at 21:59

    Sorry if you mean 3rd figure named "d" in your Q I don't think it would be a big question for someone who knows :) I'm stacked how to offset green strips per instance and keep start https://imgur.com/EUf61nV BTW your link needs some institution permission so I can't reach fig.1 in the link in your comment. Probably edit your Q at something simpler that covers my answer and create another one. Thanks – vklidu Feb 06 '23 at 20:42
  • ... or if @RobinBetts is interested to answer :) or any geo-guru here. – vklidu Feb 06 '23 at 20:43
  • The addon Nodes geometry is a powerful tool for generating structures. In the following video (https://www.youtube.com/watch?v=VBDf54D_iqI), it shows a tool that uses a special technique to generate these weaves, and especially to generate oval sections and layers between them, in this node, how to create this section? – saded Feb 07 '23 at 14:52
