Hello, I’m working on a visualization where a cloud of points hovers above a map of Cairo. The cloud’s density is influenced by attractor and repellent points that I define on the map. The idea is that the resulting diagram could reveal spatial insights about the city based on where density accumul…

you didn’t internalize geometries in the gh file but I tell you in advance, the main reason that simple definition is running slow is because of this Sphere component :slight_smile: [image] replace that with Mesh Spheres or eventually with Symbols, and you won’t have performance issues anymore

Thank you so much! That seems to have fixed the performance issue. Do you have any insight on how to build repel functionality into the script? Also, is the current way I’m bringing in pts the most efficient or is there a better way to plug multiple points into the function?

in your definition the way points are being attracted is literally “each point is influenced only by its closest attractor, any other attractor point is ignored” (and that depends on the “Closest” option of the Pull Point component) what kind of attraction behavior are you looking for?

Essentially, the points represent areas in Cairo that people are either drawn to or avoid. I currently have these locations as point objects in Rhino. My goal is to visualize a point cloud above Cairo that becomes denser in areas with a high concentration of attraction points. Repellent points, on …

this is a very basic setup of static attraction/repulsions, but I think you are probably looking for a dynamic simulation, which is just a slightly different variation of this, will show it at the end in a basic setup, for instance: [image] points in the green area are pulled toward the green c…

This is amazing. It’s exactly the sort of behavior I was looking for. Thank you so much.
