But it should. You will get the halo around the earth by that. Thats just the same. Also if done right you just get all the altitudes in between for free correct too.

Well, that is probably what you call cloudsphere. These are just the scattering integrals ... Oh, the whole world model is already there. There is the spt model loader that provides this. Load w180s90-360x180.spt with fgviewer. That just happens when you call fgviewer without model (I believe, since I have a much further developed version here). You need to provide a property config that completely switches off shaders to see something useful. But well, that's all in an early state... This even works with different altitudes in between. The lod scales in between need to be improoved. But this will happen gradually I think. > Apart from the fact that both somehow have to do with spaceflight, there > doesn't seem to be any overlap at all?! Well, it does. :) Mathias ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
