Discussion
This is an event sequence diagram of the essential events that take place as a region discovers and connects to an adjacent region. This is how the viewer is able to show more than one region on screen.
Notes
Dashed lines are UDP messages. Solid lines are events received via EventQueueGet.
This documents the successful "happy path". Error conditions are not yet covered.
This information reflects what has been discovered by third part viewer developers. It is not official and may contain errors.
