Maybe this helps:
I've made a point object (empty polygon object to which I added points manually). The deformer makes it into a sphere.
Cloner object to put spheres on each point. If you want precise control over all the shapes and sizes, you can make as many child objects as you have points and edit them individually
a Xpresso setup to move null objects to the position of the points that you can use for exporting 3d data.
