Just used the set curve normal to make diamond shaped threads. This was brilliant, thanks Johnny!

Yeah, I’m glad I was able to get that node committed! Makes this sort of thing sooo much easier! Glad you liked it!

That's nice! You can boolean it and then make the inverse. Maybe for the cap? :)

thanks... jsut what I needed... but how do I take the asset into the asset library and use it? iver tried draging it onto a mesh vehicle and get a warrning of the first socket must be "geometry" cheers

How do I make the thread end taper longer? I tried just upping the start and end points, but that quite understandably made the whole of the end segments 0, and then tapered the next one. I'd like to gradually taper the ends over a controllable number of segments, but haven't built up enough understanding of geometry nodes yet (one day!) to work it out for myself.

Wow, great stuff... how unfortunate ppl that can understand GNs are so rare otherwise you'd be like Gary on FNT (nerdrotic) with your own blue checkmark and half a million subs... (there was a time where scientists were held in esteem, to back it's _not now),_ but everyone can understand (or think they do) She-Hulk, (adult children actually watch this shite) or LaunderRings of Power (Bezos ain't gonna pay the divorce settlement with his _own_ money!) Did you already figure out the euler rotation rate based on the threading rate? I want to use this idea in one of my plexus structures as an alternative to my original design (the quadspheres will have these piston like thingies with emissive hemispheres at the ends... IF I can keep the collection materials not changing to the beat of my music I'm driving it all with... I think that's a bug not a feature. Also with collections instanced on faces, I found that there's Z fighting that shouldn't exist (how can a mesh fight itself!?), confirmed by others looking at my blend file, another potential bug (my mesh is perrrrfect)... I'm using 3.3, any thoughts?)

Hi Johnny. I tried making threads earlier using geometry nodes. In most cases the thread cross section is not circular but it is a diamond shape. But the problem I was facing is that the diamond cross section tilts when I use the spiral node. Is there a workaround for that. I guess the spiral curve node has a bit of bug that the spiral curve tilts randomly. 😐

@JohnnyMatthews Жыл бұрын

Yeah I noticed that while working on this. I need to go back to the code on the spiral node to see if I can fix that.

@Lattamonsteri Жыл бұрын

This is kind of a hacky solution, I guess, but I think I found a way. Here's how I got my thread to behave: -Connect a "Set Curve Tilt" node after the "Spiral" node -Create a "Spline Parameter" node and plug the Factor output to the tilt value. -Place a multiply math node between the Spline parameter node and the set curve tilt node. -if you have the spiral height as a parameter in your geometry node Group Input node, drag a link to a Divide math node. Divide the height value by -2 and plug the output to the aforementioned multiply math node. Now everything should work. So, to recap: The height value of the spiral needs to be divided by -2 and then multiplied by the spline parameter factor. This value is then used as an input for the set curve tilt node of the spiral. I tried this with a spiral resolution of 32 and 16 and it looked good but there are things that break the effect. If the start and end radius are different, the tilt gets messed up, as well as if one goes too low with the curve resolution. As I said, It's a hack. But there might be some mathematical truths behind all of this that I was just too lazy to explore. Maybe someone else can discover a more robust solution. :P

@@Lattamonsteri Yes, I too had to do some hack the time I used it, but since johnny had committed the node himself he can fix it in the blender code. I think it would be great if it is possible to fix the issue.
