A new, improved patch is now available from http://www.nanjika.co.uk/flightgear/Environment.diff It interpolates METAR changes over time as follows: 1) Wind changes are interpolated as vectors, so the change is much more natural than before - no-longer will your aircraft be suddenly shoved to one side. 2) Visibility is interpolated as an X-value, which looks pretty neat. 3) Cloud heights and thicknesses are interpolated if they are close to the aircraft. Cloud textures are not. Many thanks to John Denker for pointing out better interpolation methods, and Melchior Franz for answering my coding questions. If someone could review the code and check it in to CVS if it passes muster, that would be appreciated. -Stuart ___________________________________________________________ Yahoo!
