I am very much impressed by this guy's work in real time terrain rendering.http://www-evasion.imag.fr/Membres/Eric.Bruneton/Be sure to check out the linked videos on his page. The atmospheric light scattering is just mind boggling.Here's his research article on the maths, which has some real world and rendered comparisonshots at the end: http://hal.inria.fr/docs/00/28/87/58/PDF/article.pdfHere's a downloadable video showing what the scattering effects are composed of: http://hal.inria.fr/docs/00/28/87/58/ANNEX/video.avi This is what FSX XI should have become in my opinion. A pity it ended because of some short sighted higher level management decisions.Christian

He's apparently also done some real time cloud work (found under "Toutes mes publis", i.e. "all my publications")http://www-ljk.imag.fr/Publications/Basili...c7f4/index.htmlOne such person in the team can make all the difference in the graphics department of a flight simulator, I suppose. ;-)

Getting closer everyday. Love the flight over the city. Very cool effect.Cheers,MAB
