However it was no where near the best solution, but we lived with it.
When a new developer provided an integrated plib solution with a different cloud rendering approach, the "hack" was moved to the attic. Having reduced the entire 747 project down to two PCs (one for the cockpit and one for the Flightgear scenery on three projectors) was thinking of a third machine to produce enviromental effects, like a wind field using "smoothed" metar data to avoid the artifical shearing when changing stations, real-time cloud generation based on atmospheric conditions, improved earth/gravity model using Bessel functions, moving the AI to a dedicated machine and using the MP service, etc, etc. lots of ideas, very little time.....
