As an old teacher of mine used to say, a application doesn't actually work until you've used it for a certain purpose, so I just wanted to quickly show you an example that proves that my PathBuilder application did it's job very well!
Here's a test on a bit bigger level:
And here's the result of using A-Star path finding on the generated information structures:
The blue boxes in this picture represent the sectors, the yellow ones portals and the red line is the shortest possible path between point A and point B.
When time let me; I'm going to post some screenshots or a video showing a couple of AI units navigating through this level, so stay tuned =)
