THIS IS THE CENTRAL TOPIC of parametric architecture. You don't know how much this material helps us. Everything, virtually everything depends on a data tree and a list. Without these we can't argue what parametric architecture is. All our technology is centered in this exact topic.
This is the video that unlocked Grasshopper for me a couple years ago. I always send it to friends that are getting started with Grasshopper. Thank you for this great explanation !
I constructed exactly the example. This is super revealing. You are an excellent teacher. This is a flawless introduction to path mapper and masking. It's all about the data tree, lists, domains and series. This is the heart of programming and of course the loops.
I am a structural engineer and I am trying to apply GH & other plugins in my work. I understood that without understanding data management I was not going to go very far. I was looking for a video like this. Really enjoyed the approach with simple and easy steps. Thank you very much and well done on the King's Tower it looks amazing!!
I can't even imagine how intelligent the people who code this kind of app must be. Imagine being able to look at a grasshopper algorithim and then writing it in some programming language
I learned python at the same time 😳, it’s actually the same thing just syntax instead of wires. The concepts are the same, just telling the computer in a different matter. Both helped me understand the other
Not sure why you edited out connections of the algorithm as you went along. I was super confused why my stuff wasn’t working at around 9min in. We need to see the whole thing.
Thanks for your videos! I'm just a starter in GH, so much to learn ahead ... A question: I have a simple list with a bunch of items in it (the number of items in the list varies depending on modifying model inputs but it remains always(!) dividable by 4). So, a simple list with let's 100 items in it, how can I transform this list into a tree with 25 branches with 4 items in each branch? First 4 items to a branch, next 4 items to 2nd branch, next 4 items to 3rd branch a so on. How can I do it? Thx
Hi, Just one question. in 16:00 mins, you showed using data trees to isolate the branch. But doesn't command list items do the same thing? why do we need list item and the connect to data trees?
@@HandleBar3D also, this last model hat you recently build, It looks extremely exciting. Can you do a quick video on it for us to have a look? thank you so much, You are an excellent tutor:)
Nice video. Thanks a lot for sharing it. One thing I can't understand in data trees, how matching data in data trees of different depth works. It's really confusing. Sometimes it acts like cross-referencing, and sometimes like matching by the 'longest list'. But I don't understand why it's different for various cases
It depends on the structure the branches and the number of items in each branch. So lets say you have two different branch depths but in the end the have the same number of items, gh will treat it as if they were in the same depth. It also depends on the tool and other factors. It sounds like the concept of how branches interact with each other based on the hierarchy is what hasn't clicked for you. Without seeing your examples I wouldn't know exactly where is the disconnect. The rhino grasshopper forums are a good place to show your algorithm and others can help. If you do post it, send a link here and I'll see if I can help you figure out the problem.
Thank you. I was wondering how often you design with python script directly? Because my professor only teach us grasshopper design in code and there seems to be not so much tutorial for that.
qiu kailng not often, and most of the time it’s super simple formulas, maybe some python timer, nothing too bad and you don’t really need it unless your doing data export management and other high level data control.
A friend of mine tried it and from what I remember it wasn’t a very good system. I think it becomes a bottleneck if things get to complex. Not really sure though, their might be plug ins that also have streamlined the process since then. Try the site food 4 Rhino, plug ins are released all the time there.
Here's a rephrased version of your text: I believe the video aimed to illustrate how viewers can grasp the concept by visualizing data structures. However, it lacks an explanation of the purpose behind each step. You expect viewers to understand your actions without clarifying their intent. In this field, there are multiple ways to achieve the same outcome, so it's crucial to explain the reasoning behind each step, not just use components and expect results. Emphasizing the 'why' behind the use of each component is important.

These are the basics that we beginners should learn and that is wonderful lesson. Thank you for your great effort and clear explanations

I have been struggling to control the tree data...this has set me free! Thank you!
This is a great video and helped me a lot! I am a programmer, but I had difficultly really understanding data trees in grasshopper.
Thanks.
Finally someone explained what the Param Viewer does, apart from "showing the tree shape"!
thank you so much, and I would like to thank your dog, their advice about data management was so benefiting.
A great tutorial! Thank you so much! It literally opened my eyes!!!
I highly appreciate your way of introduction and getting to the flow, really great work guys, keep doing more. lets make a better world!!
Great video Ray. Thanks!
Thank you for your explanatory video. This helped me a lot. Bless you! :)
Thanks, it was eye opener for me
Thanksss a lot.. thats one of best tutorial ive ever watched on Grasshopper..
Very visually informative. Thanks so much.
Thank you for this tutorial! Would be awesome if you can make more tutorials on that topic.
This is amazing! Thank you!!
This helps a LOT!!
quite a gem of a tutorial for me!
Amazing Explanation, really usefull thanks!
Thank you, just what I was looking for!
great explanation, thanks for the video
Very neatly explained :)
Thank you 🙏🏻
This is so Greatttt, Thank you so much!
Thank you, nice video , i did learn a lot.
Thanks! I Understand them better :D

Thank you from Russia

Hi!! what programming language do you suggest learning to get better? Python ?
Bharat Arvindan python definitely
@@HandleBar3D thank you!!

I think that node is called partition node, I haven’t used gh in a minute 😂
@@HandleBar3D I will try it tomorrow
thank you that was helpful
Thank you:)

vicious bug because sometimes you need to work with a data tree group and not only the list items

nice. what did you use for the animation at the end? the rendering looks neat! :)

Спасибо, крутой урок. Просто и понятно!
Can grasshopper be used as a substitute program for signal processing algorithms instead of matlab or is this strictly for design purposes??
A friend of mine tried it and from what I remember it wasn’t a very good system. I think it becomes a bottleneck if things get to complex. Not really sure though, their might be plug ins that also have streamlined the process since then. Try the site food 4 Rhino, plug ins are released all the time there.

What books would be best to learn grasshopper ..
Thanks
I love you

this is great information, but the speech was a bit incoherent, just for advice sake, thank you!
Great but please be more clear in your descriptions, it was hard to follow
Amazing tutorial. Thanks! Can I suggest not to zoom in and zoom out so much. It is very distracting.
Excellent tutorial, but please keep the zooming in and out to a minimum!
