This is another update for the cloud code, a lot of lines but this time I have started to add the doxygen doc. Misc ==== - corrected a bug when RTT is not available, the current rendering context was altered - if RTT is not available then 3d clouds are not drawn at all - impostors lighting is now recomputed when the sun changes position - distant objects are no more seen in front of clouds - blending of distant clouds is a bit better now - litle optimization of code (uses a less cpu time) - use layer wind speed and direction (no more hardcoded wind) - fov is no more hardcoded Changes ======= - clouds (cu only) are dissipating/reforming (experimental) - compute a turbulence factor that depends on surrounding clouds and type of clouds (experimental) - clouds shapes are defined in cloudlayers.xml - type of clouds present in a layer is also defined in cloudlayers.xml - cloud layers are generated from metar and other misc. data (in progress) - added a rain effect around the viewer (enabled in the rendering dialog and when the metar property says so) - added a lightning effect (enabled in the rendering dialog) : cb clouds spawn new lightnings - added a dialog to select from different weather source : metar/property, a 'fair weather' environment and a 'thunderstorm' environment.
