Okay, now I am *really* confused. Are we trying to solve the same problem? Light scattering in the atmosphere is not part of what Earthview does at all. That is currently solved by the scattering part of the skydome shader Lauri has originally written (and which I have modified to include a haze layer and lightfields), this shader works inside the atmosphere and reasonably well outside of it (apart from a few quirks). Earthview is about getting a model of the planet itself into the scene, sort of replacing the default terrain tile system. It assumes that you have already solved the atmosphere scattering problem somehow and that you want to see a pale blue marble textured globe beneath you, surrounded by a cloudsphere. Apart from the fact that both somehow have to do with spaceflight, there doesn't seem to be any overlap at all?! * Thorsten ------------------------------------------------------------------------------ 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
