I've posted a youtube video of the FlightGear AN-2 landing at Ranger Creek, WA (taken with a cheesy digital camera pointed at my computer screen ...): But the jiggling and motion blur somehow adds to the realism of the video. Maybe we should integrate them in FG ;) Actually, I agree with that! I noticed the same thing and thought how much it added to the realism! Especially the last shot as the plane comes to a halt. Curtis, you really ought to pump the tires on that AN-2. They looked totally flat to me :-) Something I do notice though - if you do what Curtis did there and compose a video out of fly-by shots and nothing else, it gets *really* repetitive. Had a movie director shot that sequence with a real plane, he/she'd have intercut the fly-by shots with a few out of the pilot's window shots, a couple of closeups of the pilot's fact (OK, so we can't reasonably do that), and maybe some chase-plane shots. It's too late to go fiddling with it in time for 0.9.11, but maybe an idea for the future might be to rework fly-by as an option to a sort-of movie director playback mode which would allow a much more convincing (and less repetitive) move to be made. The current system certainly shows the possibilities of such a thing, and we've got out of the window and chase plane options already. It's just putting them together that's missing. Nice work by the fly-by author though. BTW - What happens if you fly a plane directly over the fly-by camera? - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Flightgear-devel] Textures, random thoughts
Hi all, One thing I'd really like to see, possibly for this upcoming 0.9.11 release, is the ability to select to use Textures.high or not. By not using Textures.high FG could perform much better on a lot of display cards I've seen (rather old test, but still apply to current FG I think: http://pigeond.net/flightgear/tests/fgfs-test-ati-20061015.html). While, telling people to move away or rename the directory is rather dumb. How many people would agree we can have a command argument to turn on/off the use of Textures.high? I have a very brief look in the code and it should be pretty easy to be selected at startup time. Probably one extra constructor argument to SGMaterialLib and SGMaterial would do it. The harder part might be making this switchable on the fly. Can't say I know the code enough to say if there's a way to flush and reload all the textures. And I don't know how useful this switchable feature would be. On the other hand, is there any good textures management method? For example, rather than enabling/disabling Textures.high, is there a way to pre-scaled down a texture before it is loaded/used? Or, is there a way to for the user to set a memory limit for textures?

This is something that could be implemented in the osg branch (and btw we should do this because using the default filterig to generate instrument texture is very bad).

[Flightgear-devel] Flightgear visualization as streaming video
Hi, I would like to use FlightGear to generate the scene observed by a UAV's onboard camera. Basically, this would translate to feeding FlightGear the FDM data and visualizing the image generated by FlightGear in another computer, across a network, using for example streaming video. I suppose this is a bit of a far-fetched idea, but is there any sort of support for this (or something similar) already implemented? If not, do you have any suggestions on how to achieve it, using external tools and/or contributing to FlightGear? At the moment I'm just brainstorming!

Re: [Flightgear-devel] Textures, random thoughts
Hmm, you should not say a lot of cards because in your test you are using an antediluvian gpu and I think that with even an fx5200 you could have your 40 fps with high resolution texture. As a matter of fact, I have done similar to another 3 different machines, either with some older ATI cards or onboard Intel display chips. Yes, those cards might be old. But I believe for those who really wants FG for realistic and open flying, or even just for development or learning, rather than for full-on eye candy, are willing to sacrifice the pretty bits. Since i'm not using a nix os I thing that a command line option without some way to click the option in a gui is dumb too. There is no way the user can know this option. Sure. But I assume that could be the job of the frontend, just like many other FG command lines anyway. Like multiplay, or atlas/terrasync, or setting fg-root, fg-scenery, etc. Or like currently to enable/disable AI scenarios you have to edit the XML file. My suggestion was simply being able to tell FG to enable/disable. Not sure if you hang on #flightgear IRC or not, but I believe one of the most FAQs around from new people trying FG is why it is giving low (1fps) frame rate. Just saw on the wiki there is http://wiki.flightgear.org/flightgear_wiki/index.php?title=Improving_Framerates which in fact mentions Textures vs Textures.high as well. I believe this is significant enough? No, and there is no absolut memory limit in the graphic card ; The driver is allredy handling the swapping of textures so there is no need to do this by hand. Sure, there isn't. Just like virtually there isn't a hard limit on how much memory a process can use. At some point the system starts to swap. I imagine similar things happen with display card which there are too much memory used. For instance, if your display has 128MB of memory, and if FG/plib/whichever knows it's going to load 256MB of textures, surely it could try avoiding that, or rescale. IIRC, though, there isn't an easy way to find out how much memory textures is going to take in memory. I know most 3d apps have textures related settings. Torcs (which also uses plib) has a setting to set texture size limit. X-Plane, MSFSX has a similar options for specifying textures limit. Btw the osg branch has texture compression so you shoud have better performance with it. Will need to try FG-OSG sometime on those lower-end/older cards I have access to :) Pigeon. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
