However if someone fires up a Mach 10 prototype they may arrive at the new METAR station with the weather still similar to the previous METAR station. e.g. It may have only changed by 30% by the time they arrive at a new METAR station if the rate of change is too slow. > Also we need to figure out how to interpolate > different cloud layers and coverages.

Personally I think the best way is to actually build new 3D cloud layers in "transitional zones" that are based on an interpolation of the METARS. Fading works but does not look very good - just try it out in FUIII and MSFS to see what I mean. Interestingly enough MS still haven't figured out a way to transition between weather systems nicely and a lot of FS2004 fans hate the way it works at the moment. It's supposed to fade in/out but the transitions are sometimes so quick (METAR stations packed close together) that there's a *flash* and a 50km long cloud front just vanished. :) It's encouraging - in a mildly sadistic sort of way - to see other people battling with the same issues. :P Paul _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
