List A: 100 random points.
List B: 5 pre-defined points (attractors).
I measured the distance between all 100 and the 5 points.
The output is 5 lists of 100 distances.
Next I used a “Larger Than” to get boolean values.
How would you use these boolean values to filter the original 100 point list?
Cull Pattern does not accept lists of differing length / structure.
This seems quite intuitive to me, loop through the 100 points, disqualify & discard those that don’t meet the if condition. But I’m such a beginner I don’t know how it’s done using grasshopper components.
Sorry if it’s obvious but I’ve been searching and can’t figure it out. Thanks.
What are you trying to do with those booleans ?
Do you want to keep points that are far enough from any attractor ?
Or do you want to associate the closest attractor to each point ?
Cull Pattern would work with a list of 100 points and a Pattern made of a tree with 5 branches containing 100 booleans. You would get, for each attractor, the list of points that are further than your criteria - but there might be duplicates across branches.
Please clarify, and upload your GH file with internalized goemetry.
Yes that’s the issue it’s the duplicates. It’s effectively culling 5 lists against 5 different criteria (the attractors). I’d like it to cull 1 list based on 5 criteria. Effectively loop through same list 5 times, although I suspect there’s a grasshopper based way to do this.
I’ve attached an image and the script for clarification. I made spheres to visualize the area where points should be discarded (for clarity). CullPattern.gh (20.9 KB)
Wow thank you very much. It’s so simple, although it makes sense I need to wrap my head around how multiplication does that, and how the branching paths work. Got a lot of learning to do. Thanks again!
