Hi guys, I'm very new to Houdini and I wanna ask a beginner question. Is there any node that allow me to query the amount of point on a given surface.
For example I have a grid and I want to be able to query the total amount of points depend on how I change the Rows and Columns.

thanks in advance.

Add an attribute create sop and set the type on detail if you prefer. the value should be $NPT
