the list will operate on each object in the branch. so if the tree is points and the list is points and i use the distance node i know that the 3 list points will evaluate agenst each tree point giving me a distance that is 40 paths with n=3 distance values in each path.
so basically all objects in a list will evaluate on each object in the tree.
with that said if the tree looks like {0;1;1;} which i will refer to as {A;B;C}where you have data in two ore more locations of each branch the list will evaluate on each set of the branch so in my previous example the 3 points in my list will eval on all objects in B and all objects in C.
i do not understand fully why grasshopper uses "trees" and not something more conventional like a jagged array object[][] or a multi-dimensional array object[ , , ]. it is an easier and more document concept to understand.…
13 5 15 6 17 7 ... …
But it seems I have not been clear:
the input values (3,5,7,9,11,13) should be presented in the way of "number slider" parameter. So by increasing the value of the slider from minimum 3, to 5, 7, 9, 13, 15, 17... I should get an output numbers of 0,1,3,4,5,6,7...
So I if choose value 3 on the input "number slider", on the other end, I want 0 as an output.
Or if I choose value 5 on the input "number slider", I want 1 as an output, and so on.
Is this possible?…
e) i.e. the points on the 5th curve of the 3rd surface where in branch {3;5}.
Your surfaces tree was like {0;# of surface} i.e. your 3rd surface was in branch {0;3}.
So you asked your Closest Point on Surface component to match your {3;5} points tree branch to your {0;3} surfaces tree branch... components are smart but not that smart.
So you need to have a surfaces tree structure corresponding to your points tree structure, i.e. for each {3;x} branch of your points tree, you need a {3;x} branch in your surfaces tree with your 3rd surface in it. Hence the duplicate.
I hope this clears it up a bit.…
“ was lost. We Strongly believe believe to bring back uniqueness in our design through Generative Algorithmic process.
Methodology This workshop has been structured so as to break the “ monotony “ in our design process. This is done through this lecture which orients the participants towards parametric process . An insight is given into NURBS based modeling software - RHINOCEROS and visual scripting plugin – GRASSHOPPER and other plugins which help them to develop their realistic project in their field of focus.

point @ 20%, curve 3, point @ 40% and so on. If I change X, the percentage of each curve changes. This way, I will end up with a wave-like pattern in my array of curves.
Upon your request, here is the code :)…
ll these 12500 points.
Group 1 would represent the point located at 0, 5, 10, 15, 20 etc.
Group 2 - 1, 6, 11, 16, 21 etc.
Group 3 - 2, 7, 12, 17, 22 etc.
Group 4 - 3, 8, 13, 18, 23 etc.
Group 5 - 4, 9, 14, 19, 24 etc.
I can create the pattern but the selection of points are all the points in row 0 and then all the points in row 5 and so on.
I would like the selection of points to start at the bottom left, and sequentially continue to the right and then continue on the 2nd row (left to right & bottom to top). i am hoping the pattern i am trying to achieve is more understood with the quick screen capture I uploaded.
the end goal is to be able to select all the points in the grid that are in each pattern.
Thanks in advance for any guidance with this. …
