In a point wrangle, I'm trying to find the nearpoint in Input 1, but I'd like each point in Input 0 to look in a specific direction (a cone around a vector attribute) and ignore points in other directions. Anybody has a general idea on how to get started with this?

One way might be using nearpoints() function and filter the point list by angle to a direction.

pccone radius? might only be in newer versions.

Thank you both! pccone_radius ended up working great for what I needed.

Does this function "pccone()"work on POPS?

wasn't pops removed from Houdini? It's been deprecated for years

It should work in any contexts that allows VEX shaders
So even POP DOP nodes that support VOPs or VEX snippets. if that's what you refer to as POPs
