I have decided to spend some time trying to solve the problem that I ran into at the end of MS 2.

After some time spent researching and re-familiarising myself with the code, I have broken the issue down to a fairly simple problem.

In the below graphs (from GnuPlot) the purple nodes are at the local origin, where the player begins, and is reset to when the exceed the 10k boundary. The green nodes are the set of nodes that are paged into view when the user walks 10,000 meters away from the origin.

What I need to do is rotate (not translate) the green nodes towards the origin, so that they essentially occupy the same space.

However, when I use Rodrigues’ formula to do this, the point of rotation seems to be the origin itself, ie, the nodes are rotation about the local origin, not the planets center.

This is what I need to fix. I may be quite close to at least a conceptual solution here.
