algorithmic modeling for Rhino
Hi All,
I have a not-too-complicated issue which I believe I am too braindead to sort out.
I am constructing a rough "solar gain/exposure" definition that is intersecting parallel rays with an array of boxes. I need to filter out only the first point which each ray intersects, regardless of how many breps it intersects ultimately. Eventually, I will be testing those points for inclusion on the subdivided rectangles on every box face.
The subdivision part is something Giulio wrote, I believe. All I need help with is getting those first intersection points only. It may be as simple as a graft I'm missing. Like I said, braindead. THANK YOU

a follow up question... how do I wrap a list onto itself at a certain frequency?
i.e. I want the list {1;2;3;4;5;6;7;8;9}
to become {1,4,7; 2,6,8; 3,6,9} wrapped every 3rd item
OK I figured that out with a partition and path mapper...
What if I want to partition a tree with one more layer of structure?
[{0} {1} {2} {3} {4} {5} {6} {7} {8} {9}]
... see attached file, with same rhino file as before
THANK YOU
I can not open you files, as I am using older version of grasshopper than you.
But the new list (one mentioned in your last reply), should have these values:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
And needs to be change in what way?
Hi thanks,
I need a to change a two-tiered list such as:
{0}
null
{1}
null
{2}
0: point a
1: point b
{3}
null
{4}
0: point c
{5}
0: point d
1: point e
___________
CHANGE TO (wrap onto self every 3 branches)
{0}
null
{1}
0: point c
{2}
0: point a
1: point b
2: point d
3: point e
does this make sense?
thanks! that DOES work... but is there a way to manage it with a variable number of branches.... say, hundreds? instead of a set number of data trees to merge, then a set number of exploded branches...
yes, but maybe I should say, I need to be able to change the number of branches, on the fly--
in other words, this is successful at wrapping it into 3 branches, but what if i want to wrap it into 8, 25, 200, etc? See attached image... If I want this parameter to be adjustable... this may be getting to a point where i need recursion/a script to get what i want...
Thank you for your help. I can understand if this is beyond the scope of asking here.
yes wizardy indeed. what I am attempting is a 3D isovist, and this one operates in one plane... suppose I could just shift/rotate that plane and see what goes down.
brilliant, thank you. now onto the containment tests....
