I want to specifically distribute points on or near the intersection line of two objects.

This is the quick sketch I came up with. the annotation is where the points should be distributed. the plane is the object which will have the geometry nodes applied.

Sketch of where the points should be distributed

I thought about using dynamic paint and masks, but they are too resource intensive or too much manual work for what I am trying to achieve.

I used a Ray Cast node in the following image and got pretty close, but I do not want the points to be inside the object, just around the edges.

enter image description here

How can I achieve this? Thanks in advance.

Edit N1:

I managed to "brute force" the point distribution with 5 Ray Cast nodes, but this is way less then perfect. If I change the location of the cube sometimes the side point distribution nodes on the one or more sides are missing. So if anyone has a better way to do this I would really appriciate it. enter image description hereenter image description hereenter image description here

  • $\begingroup$ Perhaps the Mesh Boolean node would be of interest here? This provides you with the information on which edge the two objects intersect, and you could continue working with this information. $\endgroup$

I managed to get the result I was looking for by using a Mesh Boolean node and converting it into a curve:
