Sure, it's ugly, but better than nothing. You could maybe raise or lower a layer gradually, but blending is difficult. You'd need some kind of dynamic texture generator. In any case, both methods are unrealistic. In the real world clouds are individual objects. Clouds don't "blend", you simply fly past them much like you do with the ground scenery. IMHO the price(programmer hours) / performance(realism) ratio is not favourable. It'd be better to stick with magic layers for now, and move to volumetric clouds from there. That said, if anyone wants to go the distance and write the code, go right ahead. :-) - -- Regards, "I RADIS, do you?" =Martin= http://www.iradis.org/ PGP: FE87448B DDF8 677C 9244 D119 4FE0 AE3A 37CF 3458 FE87 448B From: Martin van Beilen <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: [Flightgear-devel] New subsystem: FGEnvironment In-Reply-To: <[EMAIL PROTECTED]>; from [EMAIL PROTECTED] on Fri, Feb 22, 2002 at 04:54:44PM -0600 X-S-Issue: [EMAIL PROTECTED] 2002/02/23 21:45:17 9dccc70c8c7cdb47bb4b6660a8ca20dc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) iEYEARECAAYFAjx3/2QACgkQN880WP6HRIuLsACfa6OkaTAP+ZrOae9e7nhkXUtR CnwAn30/MvXaptp1h//VXY1I5n9R/dqx =SuAX -----END PGP SIGNATURE----- _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
