Hello,
So I've got a flat grid and I'm creating lines across the grid that intersect with each other with a clip node. And basically now I want to convert the intersections of those lines to points, but I'm not exactly sure how. I'm still quite new to Houdini, but I assume there's a fairly simple way to do this. Any help would be greatly appreciated. Thank you!
Creating points from line intersections on a Grid?

if you have lines with exactly 2 points merged together and then cut by clip SOP (all lines must be clipped) then just append delete sop, change entity to points, operation to By Expression and put:$PT<$NPT/2 as an expression
this should delete first half of the points, leaving second half which are your intersection points
this should delete first half of the points, leaving second half which are your intersection points

Thanks! Actually, I just found the “answer.”
Since I'm still pretty new to Houdini, I'm still getting use to the way the nodes work and communicate with each other. So basically, all I had to do was pipe the clip node into a scatter node and it pretty much does what I want–which is distributing the points among each one of the primitives that is created with the clip node. The smaller the primitive the more points I wanted, the larger the primitive the less. All of this will be used, hopefully, in a Voronoi fracture node to get a better looking fracture pattern.
Thanks again for the help.
