Hi Martin, I agree that this is a serious bug, and is next on my list to fix. I hope to get around to it on Tuesday evening, but if anyone has too much time on their hands in the meatime ... :) I think the root of the problem is that the Weather Scenario dialog forces a rebuild of all the clouds. I think this should be done whenever the /environment/weather-scenario is changed. -Stuart -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Re: [Flightgear-devel] 3D Clouds - patch and progress report
Hi, Yes Gerard, the clouds Heiko showed us were much more squared in size compared to your and my pictures. Georg I could fix that yesterday- there was an issue with updating the textures. I had still the one from the first patch. But of course it looks still like Gerad's one. That's the thing that makes the cloud still a bit ugly!

Hi, Here are pics of FS2004 clouds, along with the paper/video describing how it was done: http://www.ofb.net/~niniane/clouds/ This is based originally on Mark Harris Code, and was enhanced quite good. But it isn't really uptodate. Have a look here: Windmarks Nimble 3D clouds http://de.youtube.com/watch?v=pLfHDul5XGw or similar the Simul Weather SDK: http://de.youtube.com/watch?v=C9CfhyajVjYfeature=related or that: RandomChaos Generic XNA - Volumetric Clouds (only MS!) http://de.youtube.com/watch?v=uMvjai9ggzIfeature=related http://de.youtube.com/watch?v=khntLU3v_-sfeature=related http://de.youtube.com/watch?v=XlG2nwv9QAAfeature=related But we use OpenGL, so we should better take a look on X-Plane: http://de.youtube.com/watch?v=5VRWHoXMKA0 http://de.youtube.com/watch?v=Buk8_bOb5T4 And this shows pretty well how they work: ;-) http://de.youtube.com/watch?v=YkaylXZqx-E So we can see, Stuart isn't much far away. It is just this ugly borders and another thing I found yesterday: the fog has an big influenece in the visibility- it seems like a z-order thing, then increasing the fog, and the clouds disapear and the blue sky comes: www.hoerbird.net/fgfs-scree-cloud1.jpg www.hoerbird.net/fgfs-screen-cloud.jpg And so how I found out that we have acess to the clouds via the property browser- so wen can change the setting in runtime maybe with nasal etc...!

Right! Erm, these are FlightGear pictures? Seems like I have missed a lot. The ambient occlusion effect is obvious, but when did we get reflections (see the windshield in the last picture)? Only a few years ago ;-) It's another application of the chrome shader - they're not true reflections of the outside (or inside) world, but very effective indeed. Cheers, AJ And in this case we see, it has real fresnel effect!

Re: [Flightgear-devel] 3D Clouds - patch and progress report
Hi, I've put quite a bit of effort into making the clouds as configurable as possible. The cloudlayers.xml file should allow any cloud-artists to create much prettier clouds than I have managed. If I remember right, the weather informations we catch even tells us, which type of clouds should be present. (Cumulus, Stratus, Cirrocumulus, Nimbostratus, Cumulonimbus etc...) Am I right? I think, there is something like that in Environment/fgclouds.cxx So we should create the specific cloudtypes so that we can replace the old 2d-layers and having a much more realistic weather! As an example: X-Plane only has Cb's and Stratus- other cloudtypes aren't really present- but the different cloudtypes are important sign for wetaher changing etc and so it important for the pilots- FGFS gets more realistic!

Compare these (new) screenshots (NOT SELECTED) with HHS's ones. I think a remarkable difference. http://home.arcor.de/vollnhals-bremen/NewClouds_3/images.html Just to show this as it might point to a solution (???).

The cloudlayers.xml file should allow any cloud-artists to create much prettier clouds than I have managed. There are quite a few bugs to be ironed out:- 1) The cloud grid should shift when the camera moves out of range, to simulate and infinite set of clouds. This doesn't work very well ATM. 2) Currently the only well-defined clouds are cu's (used in the Fair Weather scenario). Better clouds need to be defined for all the other types. This should be possible with some new textures and editing of cloudlayer.xml 3) The alpha-blending isn't working properly 4) Rolling the camera while pointing vertically down on the cloud causes rotation of the texture. 5) The clouds are bit too transparent at medium distances. Nevertheless, I think it would be worth committing the code with these bugs present, if only so other people can have a look and comment. :) Thanks to Tim and also Heiko who provided some nice cloud textures. -Stuart Hi Stuart, Tim and Heiko! Nice to see 3D clouds again in FG OSG. Thank you for all the hard work, this should go into CVS without hesitation, after my opinion. The rain/snow stuff isn'nt perfect but in CVS, so why not this 3D-cloud starter which really compiles and works without problems and gives some of the eye-candy back we had already with PLIB :-) For those who want to have another look at the stuff, here are some screenshots from my first flight - no art, just some pics for demo: http://home.arcor.de/vollnhals-bremen/NewClouds/images.html Regards Georg EDDW - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

What is your command line ? Did you changed something in the preference files or in menus ? I'll commit the patch as soon as it works for me. -Fred Hi Fred, 1. I started FG with --enable-real-weather-fetch, then 2. enabled 3-D-clouds in the Rendering Options submenu - and did not see anything like you. Until I 3. enabled Environment = Weather scenerio from none to METAR. Does also work if I enable Thunderstorm or fair weather. As I don't know how Stuart intended it to work I only know that step 3 is absolute necessary. Hope this helps.
