It seems like they've extended the support for arrays in H14, which makes it now possible to use them as geometry attributes. In the previous versions I guess that there was no real point (but convenience) in creating arrays in VOP since you couldn't pass them downstream with the geometry data.
So if you're on H14+, it seems like you were on the right path? I've attached a working screenshot that stores every point position in a “output” vector array attribute. If like me you're stuck with H13, you probably don't need to store your point positions in an array at all. Instead, you should be able to just loop over each point with a `For Loop VOP` and do your computation directly in there. Now I've never used VOPs since I prefer writing directly in VEX so I might be wrong :) Also don't forget to use point clouds if you're after distance-related queries.
