Well, here is a simple way to actually get a qualitative feel.. perhaps you may be pleasantly surprise, perhaps you can chant "I told you so!" with conviction and a wry grin. All I'm suggesting is try it before dismissing it.
Just replace ssgDlist.cxx with this version, no other changes are necessary. If your billboards have the translucent bit set, they will subsequently, be sorted before each frame. If it works well for 500 trees and provides good visual integrity over 5000 unsorted trees that keep sporadically disappearing behind invisible walls, perhaps a more judiciuos use of LOD and fewer billboards might be the overall best result. Most Visual Simulation packages and DIS Stealth Viewers do this, which is why I'm not convinced that its completely dismissible. I would prefer to test, and report the results myself, but I'm only a lurker on this mailing list for inspiration and ideas, so I am not set up to build FSGear. :-) -----Original Message----- From: David Megginson [mailto:[EMAIL PROTECTED]] Sent: Thursday, 18 July 2002 11:00 AM To: [EMAIL PROTECTED] Subject: RE: [Flightgear-devel] ANN: a new dimension to FlightGear Gouthas, Themie writes: > If anyone is interested in experimenting, I'll be happy to provide the code > that you can toggle alpha sorting.

You might see a difference alpha-sorting, say, 5000 billboarded trees that didn't show up for a few simple polys.
