The deal with Data Trees

[@pekkariihonen8944]

Great stuff. Thank you. While I'd like to think I'm a "seasoned, hardened veteran of data trees" in the words of Mr. Rutten, I value this kind of revision enormously. More is very welcome.

great one !! looking forward for the Part 2

great explaination, I think the difficulty with data structure is how people understood them when they're first being taught. Like you said in the begining, this explaination is for people who already have experience with GH. When an instructor is teaching, they'll usually just teach flatten and simplify to solve all problems, cause it becomes too difficult for beginners to understand. This causes problems when people start using them extensively as a habbit, and later becomes difficult to change.

Thank you so much for this Andrew. Great presentation with a great deal of care and love.A second video with practical examples would be amazing.

Finally got around to watching this video. Coming from more of a computer science background, the input matching discussion at 10:50 was an "Aha!" moment for me since I was expecting a more "nested for loop" type operation resulting in a data tree rather than "pairing" operation resulting in a single list. Now at least I understand that data trees are meant to help me grapple with the inherent one-to-many and many-to-one relationships in geometry. Will see if this makes things easier in practice...

Thanks a lot Andrew! I watched quite a few videos about the data structure of GH, most of them gave me an understanding, but yours elevated it to a level where I could implement it and solve my problems. I’m new to grasshopper, but not new to matrices, vectors, lists etc. Your video gave a clear set of rules/guidelines that made me solve a data structure issue I had for a week. Having a bit of sql and Bi knowledge the one-to-many, one-to-one etc. way of explaining it is really nice, further more the “don’t flatten rule” helped a fair bit :)

Great presentation, I'm right at the point in learning grasshopper where I have to understanding what these trees are all about, and this helps a lot!

[@romain3276]

Really useful, thank you! Data tree handling tutorials are rare but essential for advanced operations. I came to the same conclusions as you after a lot of painful trial and error. Looking forward to more videos on trees.

[@noahglynn]

What an absolute legend! Thanks Andrew. I'd love to see a part 2

[@Lex.Dachstein]

Great video. I´m looking forward to part two. :)

[@aaiddinn]

This was amazing Andrew. Thank you for putting the effort to make this, hope you do part 2.

[@TimHalvorson]

Andrew = The Master. Thanks for your thoughtful considerations! I haven't explored Treesloth much and would love to see how that and other more advanced data tree management components are helping streamline your graphs. Thanks again for taking the time to compile this video I think it's a great one to baseline people's understanding. Cheers!

Highly appreciate your time for this well-illustrated explanation on such an important topic. Extremely helps in getting the basics right!! I wish I had such a resource during my early stages of learning. Although, your rules and best practices are certainly insightful. Looking forward to part 02. Many Thanks! :)

[@serkanyavuz6227]

thank you so much for your help also for the amazing plugins, hope we see more of you in the future

[@bartomiejtokarzewski7741]

Greatest presentation about data trees, thank you!

[@mahmoudalaa3260]

Great explaination Thank you I'm looking forward to the second part .

[@sebastianaguilar8356]

Thanks a lot! I would be great if second part is released! :D

[@micr0n0va]

It's been a while since you posted, but thank you, this helps tremendously.

[@shankargope2475]

Hey there Andrew, Thanks a lot man for breaking the concepts of data tree to this much level 🙏 Really such an amazing discussion around the core concepts of data tree 👍Loved it 💘

[@dutubinger]

Wow!! such an amazing explanation ! Thank you very much for this really great Video! it made many things clear to me!

[@danielhung216]

thanks~ super helpful and clarify many blind-side of my formal way of using grasshopper

[@maherjebbeh7748]

Amazing explanation Andrew, it's really really helpful

[@3dbits_art]

Great explanation - thanks a lot for sharing! Same as almost all previous comments from my side: Yes, I would appreciate if you make part 2 of that video. Even subscribed to not miss it.

[@pedorthicart1201]

Some people are gifted to learn others! Thanks!

[@noon1858]

Oh waow - I was about to thank you and I found out that I did last year! ; but hey, thank you again and again and again =)

[@arunprasad5127]

Thankyou so much for this valuable information !!

[@horsee45]

Fantastic explanation. Is there a Part 2?

[@tianhanzhang4939]

Always love your videos

[@matheox4425]

Fantastic video, thank you.

[@BMBijoutiers]

Great ! Thank you Andrew

[@noon1858]

Thank you for the Lecture

[@amr95ahmed]

This is awesome!

[@ВалерийГорбач-п7и]

sumptuously! I'm waiting for the continuation ... the topic is very difficult to understand. I would like to ask you to supplement the lessons with examples on real simple objects I want to understand what happens to surfaces

[@maurishmelian932]

Perfect video!!❤❤❤❤❤ I'm searching for "part 2" and I don't see anything! 😢😢😢

[@nrosquist]

fantastic!

[@archistudent6124]

Thank youuu so much❤️

[@leonardogindri1744]
