Calculating orbits

[Kaputtnik]

Hello all,

I am new here and currently trying to get the hang of plugin developement for KSP and have done my first steps in creating a scenario module and its running fine so far. Now I have the problem of a lack of documentation for the API an before I waste time trying and failing, over and over again, I wanted to ask you for help.

I currently get orbit information from FlightGlobals.Vessel and FlightGlobals.fetch.VesselTarget. But those are in reference to the current main body of the vessel and the target.

How would calculate an orbit of a vessel around a body, where I would suppply the vessel and body. Is there a way to do that?

And how would I calculate the Ascending an Descending Nodes of two orbits (vessel and target). They are displayed in the map view. But I really have no idea where to find those values.
