Acquiring and selecting individual points

Goodevening all.

For a project I'm trying to optimalize a voronoi structure. Because I'm new to rhinoceros/grasshopper, I'm trying it first on a simple '3 cell - 1 node' structure. The file is pretty simple: I place 3 points in rhino, select them in gh and create a voronoi structure. I then use a offset-curve to create thickness. By using ControlPoints I can find 4 points in the node created by the 3 cells. To optimalize the structure, I want to create another cell inside that node - based on those 4 points. Now I can bake the end result and grab the points, but as you might understand - this is not gonna work well with 3d/complexer models. Is there a way to acquire indiviual points in GH and select the ones I currently want/need. So with complexer models: having a list of points so I can select the points needed to create a new voronoi cell.

This is what I currently have. Anyone have an idea how to proceed/what to do?

I apologize if my judgement is wrong here, but I think you should read up the Grasshopper Primer in the Tutorials section on list and tree management. This should tell you all you need to select individual points from a list.

For polygonal curves it's better to extract vertices with CurveExplode and connect them with PLine.
