is there a way to retrieve a point given a point number/id in a geometry using vex or python?

from what i see so far, it seems like i have to iterate over all points in the geometry to find the actual point. seems like there is a way to do this if it is in a cloud or particle context (i forgot exactly what context it was) but i just have a normal geometry.

Looks like this VEX node might be of some help?
