Grasshopper 101: Data Filtering | #07 Item Index, Member Index, List Item

[@sergeyzhigalev]

I can`t understand, why there are so few likes on this particular and other your tutorials. They are just excellent for beginner! These are basic tips of crucial importance for further practice, carefully explained step by step. Thank you very much for it. The only flaw of this course is speech volume, I turned to limit both system and KZbin sound, and still rather guess then hear what you say

[@learnvisualprogramming]

Thank you for the comment and generous feedback. We're glad you find our content useful. Be sure to share this channel with others who you think would benefit from it! I believe the volume issue has been fixed in the future videos, but if you're still having issues, please use the Subtitles/Closed Captions option.

Exactly, I really appreciate how she go through everything with sufficient examples so you really understand everything

[@Carambolases]

I kept studying on grasshopper and.... had no clear understadning of the structures and logic. Now I can understand more than I did before :) Thanks and I will keep up with the materials you uploaded!

[@learnvisualprogramming]

Thanks for the comment, glad you enjoy learning with us!

Thank you, I think this video is a bible of List component.

[@royaleguru]

Thank you...Very well explained!! I think more louder could be helpful

[@learnvisualprogramming]

Thanks for the feedback. We'll have that in mind for future videos.

[@TechnicOffice]

thank you

[@computationdesign]

thank so much

I'm trying to find where I have duplicate points. I use Cull Duplicates but I can't find the inverse of this list. Even if I use the Indicies provided I get the same list. I do I invert indices from the original point list using that cull list? Thanks

[@ScottValentine]

Figured it out finally. Cull Index using the Indicies from the Cull Duplicates.

[@learnvisualprogramming]

Yes, that's exactly right! Also, don't forget you can adjust the selection by changing the component options (right-click on the component). The Valence (V) output can be useful if, for instance, you'd like to select (or cull) only those points which have a certain number of duplicates.

[@tahirzahidishrat1324]

Thank you! You've explained it really well. Can you also tell me how do you change the index numbers? For instance if index 0=A, 1=C, 2=B, and I want to make 0=B, 1=A, 2=C? I'm asking since I have a 2 lists of points whose index orders I want to match

[@learnvisualprogramming]

Hi, thanks for the comment. Depending on your objective, changing the order of items can vary from being very simple to complex. I would recommend skimming through this playlist: kzbin.info/www/bejne/n3_Fg4iNgppoprc You could also try visiting the McNeel forum, or contacting us directly via email with specific details and the Grasshopper file.

[@ScottValentine]

I'm not sure where it would be useful, but can the Index parameter take a range or even random numbers from a range? It should be able to right? It's just referencing a sequence of numbers.

[@learnvisualprogramming]

Not sure I understand your question... If you inquire about an Index(i) input (for instance in "List Item"), then yes, it takes integers and it doesn't matter how these integers are generated. Accessing a specific selection of items using their indices is a very common operation.

recorded voice volume is too low

[@learnvisualprogramming]

Thanks for the comment. I believe we have solved this issue in more recent tutorials.

[@CMRHM]

that Item List component is weired, I guess it is useless?
