I have been toying with the idea of how to teeny tiny baby step into learning grasshopper. With the goal of creating videos for others who like me have been befuddled with it.
Brian G was kind enough to answer my many questions and the result was this-
I’m calling that a small win in the Japanese spirit of getting just a little better each day.
Is this voronoi has a name? I call this hammered pattern, but not sure if this is the correct name.
So this is how everyone felt when Apollo 11 landed and the first man on the moon made history
Godspeed you brave soul. 
Right?!?
Kinda like when Dylan went electric…. hopefully there will be no riots over this.
I may actually call the video for this
“so…hell just froze over” 
I have so very far to go, but going from mild panic and stomach upset while @brian so patiently walked me thru the process to beep boop diddly blobs and spaghetti wires to holding a printed part in my hand all from the comfort of my basement office…
got to admit…pretty heady stuff..
now, I need to start looking for a desktop cnc so I can start cutting metal…
@brian made some gorgeous glasses last year and refers to this style as Battuto…that may be a glass specific term I simply heard others say and am repeating without fully understanding.
So.. If I’m wrong, I’m going to be wrong, but with confidence. because I’m an american god damn it. (but unamerican in the fact I will actually admit I’m wrong if presented with better info)
The cool thing about this process for me is the idea on how to baby step into using these tools…
”learning grasshopper” is just so overwhelming for me and I gather many others, because to some extent you have to learn A LOT before you can do anything, including how to “think” like a programmer.
I have been picking at the idea of how to teach this to people who are as challenged as me for a long time and this is the first little peek at how it’s going. Small wins, and I’ll keep posting my progress until I get something useful I can share.
At the end of the day, it’s just one more facet of this amazing tool and community that Bob and his crew built…and I sincerely enjoy every moment I get to play.
Your knife is too sharp. I almost cut my finger while clicking on the image. Damn… 
I’ve been thinking about grasshopper for like the past month back and forth..
Could it in theory be used to program stuff like Arduino or servo motors ?
I’m thinking like: Rhino+grasshopper+Arduino+ servo motors+3d printing combo.
Looks great Kyle! Ive been using it for similar texturing . I look forward to seeing more and videos.

yes, @AndyPayne has a lot of experience in the arena and would be the 1st person you should talk to about that.
yes in german we call it hammerschlag effekt (which means exactly that) mostly used to describe a paints ability to form such a pattern
but probably also for this kind of finish in general.
Now, if we can just get Kyle @theoutside to join us in the modern world and do his training videos in metric units the Holy Trinity will be completed!
Oh I crack myself up…

Plenty of US and UK companies and regular people adopted the Metric system in the recent years. I have seen so many videos by car builders, and any other type of business, who measure with Metric tools, and they seem comfortable with it. This map map does not show the full picture.
I’ve never gotten into GH, my brain just doesn’t get it without spending ridiculous amounts of time trying to soak it up. Be good to see an ‘idiots’ series of GH videos, knife looks sweet btw 
IMHO, being able to use GH in any capacity is a huge advantage. All I do with Rhino and GH is create things primarily for 3D printing and shop use. Not into sophisticated surfaces, etc. Just average guy stuff. Here is an example:
The “hammered” look is NOT created using any voronoi. IIRC, when I wrote the GH file, I offset the surface, then populated it with points, created random sized spheres within a range and then subtracted to get the hammered look.
All of it was basically created using GH. I have a definition that allows me to work with the basic shape quickly and easily exploring forms. Sure, this can be revolved in plain Rhino. But it is nowhere near as dynamic.
BTW, for all you fans of AI. . . . the picture is a real vase that actually exists, the background to the picture is not real, it is AI generated.
I many be wrong about this, but it seems to me that all voronoi cells typically have a maximum of 5 sides? The technique I described above has shown as many as six sides, there could be more, not sure of that either, and I don’t much care.
The best advice I have is to start out with some smaller projects. One of the issues I had, and still have is knowledge of all the components and what they do. Finally figured out that I only need to know about the ones that I typically use and if I come across a challenge it is time to do some research on line.
A really good resource that I use is CoPilot (MicroSoft Edge AI). I can ask it things like:
“describe a grasshopper routine that will allow a user to control 4 points to create a smooth flowing curve” and it will produce a step by step procedure that includes components to use, where they are located and what they do.
A side note, sort of not related, but kind of is. There are times I would like to smooth portions of things I have created, especially organic items. Started using Nomad Sculpt. Inexpensive, they now have a desktop version, and it does not require an advanced degree to use. Point here is, using ALL the tools available really improves quality of work.
That looks neat. Is it real or rendered? If it’s real, what material is that?
you really want to watch me try to do math live on the fly? bro…I thought we were friends… 
1st image is a rendering, images farther down in later posts are 3d printed pla.
fiddled the blade shape a bit at the top where it joins the handle for better visual flow, made the finger flick a thru hole and added a Rhino logo to the blade.. Fwiw I did all teh filleting on teh cells with the edge blend tool, and predictably there were some failure points, I was able to manually trim the shapes I wanted and then the new patch tool worked BRILLIANTLY to make multi sided surfaces with g1 continuity. A task the before this tool would have been literal modeling hell…
This has been a fun project. Much learning has been learned.
I may fiddle with a lock mechanism built into the brass pivot it’d be pretty elegant to have the blade lock when out, and then squeeze the buttons to unlock it for folding
LOVE nomad sculpt.
No worries, here in Italy we call it a “battuta” texture too. Even in the footwear industry it’s the same term.
If you ask someone “do you want a Voronoi pattern instead?”, the answer you’ll get is: “a Voronoi what?” 
So you’re perfectly fine using “Battuto” — it’s a real term, and people actually use it.
Funny thing is, when people here say “battuta”, what they actually have in mind is the old-school idea of a hand-hammered surface — literally done with a hammer. The term comes straight from that tradition.
So yeah, using “Battuto” is completely legitimate. It’s not some fancy reinterpretation; it’s just the digital version of a process that’s been around forever.
Battuta/o literally means hammering.
