Hi simple-life,
Here are two ways to create this:

The first one uses the surface deformer to place a tiny polygon, a "mesh matrix," in a cloner.
The other file, "11.c4d", makes the abc file "editable" [c] and allows so access to the point data (yes, you asked about this, and file number one doesn't follow this question).
A single point is insufficient here, so I introduce the Target Tag. With three points, preferably from a single polygon, the position is taken, a target, and an Up vector, which allows a stable orientation.

(Perhaps set the XPresso Priority higher, or later in the Object Manager)
Let me know if that works for you.
All the best
