just need to adjust the filed a little, fields are so random anyway,
can change the scale of the noise:
the pinch is just not enough definition in the sample grid:
scaling the noise:
height is mapped to whatever domain and graph you want
gaussian point charges:

This is a nice solution - it’s neat, easy to follow from the image you posted and has reasonable control over the final outcome so I ticked the solution box here even though there are other ways to do this kindly posted in the thread above!
Thanks again for sharing this and highlighting the Heteroptera plugin!

Pretty happy with this as an oak frame… doesn’t need a picture!
Lots went wrong with this…
Mitre joints were appalling.
CNC Router Spindle died halfway through machining
Machined the pattern slightly too deep and needed some rework
Wish I’d tweaked the top left hand corner a bit to have closer ripples.

Nice.
How about gluing the mitered pieces to make the frame before applying the CNC?

I did, but I didn’t pay attention to the flatness of the oak when I cut it and the mitres were terrible!
Many options, a) use the cnc to cut the miters, b) mill from a solid piece of wood, or c) incorporate the visible joint into part of the design aesthetic, or d) make joints a ‘puzzle piece’ fit, e) make the joints a ‘sine wave’ fit , f) the list goes on
Yes, I’ve done all these things in the past. b) is often not possible as pieces of wood big enough are either prohibitively expensive or do not exist. I’ve machined puzzle piece joints which looked good (getting the right clearance can be tricky)
What I did wrong this time was simple… The timber had been planed years ago and I assumed it would still be flat. Unfortunately there was a slight twist or bow which must have meant the saw did not cut at 90 degrees to the front face. So my 45 degree angle was OK but because the edges weren’t square it left and equal but ugly gap along the mitre and I didn’t have a proper clamping system that would close the gap.
Hi, I didn’t find this component “ sample field at points ”, can you tell me where I find it ? … regards
Use Evaluate Field from Legacy Grasshopper
Thanks
fwiw-
it’s customary to buy art from others as opposed to asking for it for free.
you wouldn’t go to a grocery store and say “hey, gimme some of those apples will ya?” and expect them to just hand them over. Grocers sell groceries for a living.
Artists make art for a living.
thanks for coming to my TED talk.

how do i apply this turbulence to a tube whereby there are no visible pattern interruptions and the whole turbulence rolls around smoothly on the pipe? at the moment i made a flat plane with the turbulence and did flowalongsurface on the pipe but the junctions don’t match - thanks
Hello
Yes you surely can. But you ll have to be more specific.
I am trying to make a tubular shape (size approx 10 meters tall and diameter approx 1.5 m. The tube needs to feature turbulence as if it were water falling from a tap frozen in the moment, or like sinuous waves. 1.5 m diameter is the miniumum so some sections can be wider but the wider sections have to be elliptical so that one side is always no more than 1.5m - this is because the final structure has to fit through an opening of approx 1.5 and the ellipse can be rotated to fit in the hole as long as one “side” is 1.5. As a reference look at Ross Lovegrove’s Ty Nant plastic water bottle ( https://tynant.com/products/ty-nant-by-ross-lovegrove/ ) - I am no grasshopper expert but need to create this shape and I’m going nuts… I then have to cut the shape in 48 vertical strips so that this can be constructed. As a reference for this look at Dancing Lantern by Sophia Michopoulou ( Dancing Lantern by Sophia Michopoulou|Hanging Lights) - thanks
I tried noise_on_mesh LD script but the pattern it creates on my shape is too aggressive and not sinuous enough
This uses Heteroptera plugin but I’m sure you could do something similar with Nautilus etc…
It creates a surface in a vase shape and turns that into a mesh and applies the ripple noise pattern.
I’m sure you could create a cylindrical mesh instead. Lots of parameters to play with!

this is really cool, thank you for the script - i substituted the vase with a tube and it works well.
