Re: Cel Navmesh testing for Planeshift

Hi Anders,
Thank you for trying out the code and for highlighting the difference in
appnavmeshtest, I see what you mean and will update that today so that the
two versions are consistent.

I think given that you already have your code in place to work with the
previous version of navmeshes and your navmeshes already constructed, there
is no benefit for you to switch PS to the latest code yet. The improvements
I have made this summer are beneficial to the creation of navmeshes and use
within an app (i.e. you no longer need to manage the navmesh memory in an
app, it is handled for you within the plugin.) These benefits are,
therefore, more useful for those developing new apps.

The biggest change needed, and I think we agree here, is to improve the
behaviour between portals. For this I think there needs to be a
significantly different approach as the current method is simply not
functional. Matthieu Kraus had some detailed ideas on this when I was
proposing this project, unfortunately there has not been time to explore
them fully as part of this GSoC. I would be interested in hearing his
thoughts on this again and perhaps designing a new solution.

Kind regards,
Sam.
