Interesting. After much trial and error, I managed to get a basic visualization system working for tracking AI traffic (see my question yesterday). My current implementation is taking a similar approach as what is used for generating runway and taxiway signs and also uses a simgear effects class. Because I use this system for plotting routes that are active, the system is quite dynamic and involves a lot of regenerations of the corresponding scenegraph node. During some of the early tests, regenerating the entire node on a frame to frame basis caused a dramatic slowdown of FlightGear, even though I am 99% sure that the old versions were appropriately removed from the scene graph and deleted from memory. I wonder whether the slow-down is related to the aforementioned effectMap bug. Anyways, my code is still a long way away from being production ready, and the visualization part is one section that probably needs a second opinion. All 'n' all, the AI/ATC interaction is progressing nicely (as long as I don't get distracted by launching Vostok's into space that is). :-) Cheers, Durk ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
