How to apply Voronoi lattice structure on any geometry in Grasshopper

[@Jp-wp6vf]

Hey, thanks for the tutorial. Unfortunately, you skipped a step, which means it no longer works for me. You skip the part where you connect Voronoi B(5:51). You can't see or understand what you've connected it to. Unfortunately, I get the message for Solid Intersection: "Boolean Intersection set is empty"

[@belabezold1485]

i have the same issue

[@mayteidarraga58]

Same here

[@mrmb380]

I know it is already too late, but the voronoi is connected to a relay that is connected to the scale node. I ran into the same problem, you can spot where he connect it to later on in the video. it's very easy to miss, took me an hour to figure it out.

[@lean99zz]

I feel this is one of the first and only good grasshopper beginner tutorials.

First of all great Tutorials - keep it up! Secondly I'm stuck at 5:26 because I dont know which bounding box/brep I need to insert in the *Voronoi 3D* component

[@jukama7671]

I searched and looked and it is the last thing of the very first group, the scale note. It goes into a relay node and then into B from the Voronoi note. Sadly it still doesn't work

I'm having an issue with my model. Not sure if it's because I started with a brep instead of a subd. Everything works up until the multipipe command converting to a mesh body. The multipipe populates but the mesh does not. Any advice?

[@lpjunction]

This is an interesting way to make carbon fibre structures. Say making bicycle parts. First 3d print the swiss cheese structure, then poke in long straw in either the x-axis, y-axis etc. or even in rings like a coil. Then put in the carbon fiber in the straw. Next pull out the straw but leave the carbon fiber remain in the cheese. Repeat the process to insert more fiber until the structure is full. The final process is to impregnate the cheese with resin. Such structure should be stronger than other methods.

[@scottmayson]

Nice, I like using Dendro over multipipe to mesh curves.

[@3DBeast]

Thanks. voxel based is another alternative. but don't give good mesh topology.

[@peterlaverty9397]

Fantastic tutorial. I see in your final render there are some deformations. Also can the mesh be closed for 3D printing? Did you 3D print the red one at the start of the video? Thanks again.

[@3DBeast]

Glad you enjoyed it, if you get intersection results while getting an Orange Warning, leave it and proceed to the next process. It will be fixed after the Point filter process. But if you don't get any intersection, possibly, you could try out flipping the brep (in case the face flipped).

Hi all, I need some help: I followed the tutorial, but I found that there are unjoined parts of the voronoi. This causes an open mesh. How can be done to eliminate the tubes that do not join?

[@mrmb380]

I think i know what your talking about, is it the part where he skips a step, so you end up not knowing where the Voronoi bottom part is connected to. It's connected to the relay that is connected to the scale node. (you can spot it at 10:17, where he zooms in you can see where that connection is connected to). Took me an hour to figure out what I was missing. (total 3 hours)

Everything else works perfectly.

[@3DBeast]

The error you're seeing typically occurs when the script is expecting a Brep but is receiving something else, Make sure you set the Hint for both inputs to Brep (Right-click on each input, select Hint, and choose Brep)

How to make point of brep true??

[@asd-fw7yb]

good, but very complicated to use Grassopper... it's a task for a visual programmer, not for the average Rhino user. (it's similar in BLENDER). Playing with Grassopper is not for everyone.

[@SeinfeldDeng]

Is this method suitable for the sphere shape subD? There are always some weird sharp burrs outside the sphere lattices, I just can't figure it out.

[@SeinfeldDeng]

Finally, figure it out, the "Merge" component's output must switch to the "Flatten" mode to exactly merge two bunch of points together, which allows the "Voronoi 3D" to generate the correct cells.

[@julesmoizan8893]

So I don’t know if it is a hardware or software issue but once I get to the voronoi 3D part it just lags like crazy, takes a solid 5 minutes of loading once I’m at the merge component and I put it in the voronoi 3D. I have a Ryzen 7 4000 series with an rtx 3050, maybe it’s not optimised enough for grasshopper although I usually have no problems using other softwares like blender, clo or even rhino in general. By the way great video, the explanations are really well done.

[@sufialqaisy]

wow , thank you very much

[@kummer45]

Is there a way that I can organize that lattice without using voronoi cells. Of course the answer i the classical lunch box tools or reparametrization for even surface subdivisions. Are there any other strategy for the same voronoi cells but organized? I'll work with the classical gradient triangulations. :P Besides this is example opens the pandora box to more complex structural systems that are organized and those that are randomized. Optimization may come later. As usual, 3D beast being 3D beast. :P

[@3DBeast]

Yes, indeed! You can experiment with the point placements. The randomness comes from the randomly generated points. You can try out an organized point grid for a more structured result.
