I'm trying to build a nature scene with geometry nodes, and I want to make sure that plants aren't exactly on top of each other. For example, I don't want grass growing inside of trees and sticking out of the roots.

The way I thought about going about this is to make a point cloud for the most important objects first, then when I make subsequent clouds, they can be filtered out based on the proximity to the original cloud. How would I go about this?

This might be a solution:

enter image description here

After converting the point cloud of the trees to geometry with Points to Vertices, I simply use the node Geometry Proximity to check if the grass is at a certain distance from these points, and use that as a selection when instantiating.
