I once tried a very quick experiment with a sort of blobby shape a few thousand feet across, to see what it looked like. Replaced a slow a/c model with it and flew it around a bit, watching from the tower. Looked too ephemeral (sp?) with just varying the alpha in the texture. Along similar lines, technique-wise, I've been thinking about an horizon object. Trouble is it needs 360deg sequences... :( However, one of the 'plasma' type algorithms, as used in those old Amiga demos, might be adaptable to generate a suitably changing 360 image. Might only need one iteration per 10-40 frames, and you'd only need to render the visible portion... ...dunno :) LeeE _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
