Re: [Flightgear-devel] 3D clouds and precepitation affects.
One more observation. Yesterday I was doing tweaks to the spin related functions in my model and during spin tests I noticed that I get the same affect when I am in a spin only the clouds are rotating about a vertical axis rather than a horizontal axis. Again it only appears to happen in vertical maneuvers. In a spin this is very disconcerting as the clouds spin in the same direction as the aircraft. Yes - same reason - rapid change of the orientation of the view axis. The problem is generic: a real cloud is a 3-d distribution of droplets, i.e. for rendering purposes a function f(x,y,z) of opaqueness where projections like \int f(x,y,z) dz = c(x,y) determine the appearance of the cloud as seen from the z-direction. I don't quite know if one could render that in real time if enough interpolation is used (I'm no 3d rendering expert), but even coming up with a physically correct f(x,y,z) which projects in all directions into something like a cloud is a pretty hard task. So we have to fake it by using texture sheets projected onto something, and then there is always some situation in which the nature of the fake is apparent. I can given you clouds which look more or less realistic in level flight and normal airplane operation (by using rather high-resolution cloud images as done now) - but they rotate in an odd way when you do aerobatics. I can give you static cloud sheets which look great from far below or high above - but they look unrealistically flat when level with them (doesn't work for convective clouds though - I did some of the Cirrus sheets that way). I can give you clouds which are stable against the rotations you observe in aerobatics - but they behave in an odd way when you are close to them. I can give you clouds which are stable against aerobatics and have the right behaviour when you are close to them and look straight - but when you look out of the side window or take an external view they look odd. The problem isn't going to go away - you simply can't make a 2d sheet appear like a 3d object without the 2d nature being revealed somewhere, in some situation - it's like asking from a stage magician that you should be allowed to sit and observe behind the stage as well - if you want something which looks always and everywhere like a genuine 3d object, you need a genuine 3d object. All you can do is decide where you want the problem to be. And I guess that having clouds which are stable against an airplane flying through them are more desirable as clouds which look good from a spin... But you could simply edit the cloud shaders to insert the relative position vector to the object as the reference vector for the transform rather than the view axis just to see if you like that better - it's one line to edit I think. Stacking many 2d illusions into a 3d volume is a step towards a genuine 3d object, and Tim appears to think it can be done I've been looking at the clouds code again recently, which is oddly slow on my monster machine (Phenom II x6, GTX 460) . It has the same problem that the trees code did before a big makeover: it uses instancing techniques on geometry (flat quads) that is to far simple to be treated as an instance. It would be much better to take the same approach we do in trees and treat a cloud as a list of quad or triangle polygons. The messy part is the distance sorting that is not optional for the cloud sprites. (I have no real idea as to what all this means... since I am not a 3d rendering expert). But then you run into a different problem - right now, the cloud code doesn't need to know any convective physics, because the cloud texture is a photograph and has all the information where a cloud looks how. If you break that and build the whole shape from 200 different elements, you need to input the whole information about where the texture should look how yourself, i.e. to get the same visual quality, the code to place the texture elements must have some rough idea about convection. There's no free lunch... So, I guess rather than more information where the current cloud schemes fail (which I at least know, I've spent 3 months with dreaming up and testing schemes adn trying to come up with workarounds), an opinion where you would like them to fail instead or how much performance you would be willing to throw at improved clouds would be more helpful to make progress :-) Or if you can come up with an even better scheme/transformation, I'd be very excited!

Hi Roberto, Just for the record (and to echo Martin's suggestion) FlightGear supports a variety of multi-monitor configurations. 1. The old/expensive way is to have one PC for each display and then sync them together over the network (one master server + n clients that sync to the master.) We have supported this natively for many many years. 2. For the last 2+ (?) years we have supported multiple displays attached to a single PC. You can get motherboards with multiple PCI express slots for multiple video cards and typical nVidia graphics cards usually support 2 monitors each. I have played with a machine that had 4 video cards for a total of 8 monitors, and Martin and Torsten and the FSWeekend group had a machine with 5 video cards for a total of 10 displays. FlightGear is based on OSG which supports a highly threaded architecture, so you can run multiple displays on multiple CPU/core machines and have quite impressive results. 3. FlightGear also supports drawing a camera view to a portion of the display. This provides excellent support for devices like the Matrox Triple Head 2 Go box. Your computer thinks you have 1 large display, but you can divide that display into 3 separate camera views and set the view parameters for each camera. This allows you to account for the frame around each display so that straight lines in the scenery line up from one display to the next and you avoid stair stepping of the horizon in turns. 4. More recently, several of our developers have been looking at supporting curved displays ... like projecting onto a wrap around cylinder, or even a parabolic curved screen to produce a collimated display (infinite focus/3d) like the multimillion $$$ full motion sims use. This code is just being hashed out right now so it's not ready for prime time. At the moment we are building the hooks and Tim has a simple demo of a transform that would be appropriate for projecting inside a dome. This is all very exciting stuff, especially for those that are interested in home cockpit building and pushing the state of the art forward and mimicking what is done at the absolute top end of the simulation world.

Just for fun I threw an img tag at the bottom with a B1900 cockpit photo ... will facebook pick that up? Thanks, Curt.

Re: [Flightgear-devel] FlightGear Flight Pro Sim Statement
In order to promote our statement, I've created a YouTube video, explaining some basic things about FlightSimPro and the like, and reference the viewers to our statement. If we all vote thumbs up on this video, add it to our public playlists, make it favourits etc., it will come up higher in the search results and thus be more visible to potential buyers. It's already third in row when searching for FlightSimPro! The video: http://www.youtube.com/watch?v=s6LAWlRaydo Comments/ideas on the content of the video are welcome of course.

Re: [Flightgear-devel] ProFlightSimulator The Most Realistic
Hi FlightGear folks, (I am only temporarily posting to the dev list. I'll remove myself following this interchange about ProFlightSimulator). I'm posting because I was so infuriated as a consumer about the ProFlightSimulator that I bought on Nov. 23rd for $50. It was not what I expected at all, UI-controls-wise, and in any case I could not get it to run. I posted a complaint via their tech support site, asking for my money back. I then cancelled payment via the American Express complaint site. I then dug in to see what I could find: -- There is no company name on their web site. I browsed through several pages until I found this: Dan Freeman 13 Hickson Road, Walsh Bay, Sydney, NSW, Australia -- I searched for complaints and went six pages deep in a Google search without finding anything. It appears that Dan has flooded the internet with bogus reviews such that not a negative word appears. He also has a couple sites that are _bogus scam expose sites_(!!) that report back that ProFlightSImulator is a great product! -- Finally down in page seven of the search I came across messages that originated in this list. I read all of those, and now feel all the more infuriated to find that your good work has been expropriated for profit. I am sure he is raking in big bucks, as, to a novice like me,* it _appears_ to be a breakthrough product that is better than MS Flight SImulator!! Their site has this guarantee: To back that claim, you have my 100% Risk Free Unconditional Money-Back Guarantee. If after 8-weeks of using this simple, yet powerful 3D software and you're not satisfied - I'll refund your money...no questions asked. I am waiting to see if I get my money back. Thanks for your good work on FlightGear.

Could be a similar problem this time? -Reagan Gijs already confessed that he changed the model-hz to 30Hz. The gear model code just isn't robust enough to take a large transient at that low a frequency. When flightgear starts, it places the aircraft above the scenery and lets it drop. At the normal model-hz (120Hz) the gear model does a good job of absorbing this impact, but as the frequency drops quantization errors cause the gear model to misbehave.

[Flightgear-devel] (no subject)
To whom it may concern, I note that you are hosting articles created by author Dan H Freeman. Please be aware that Mr Freeman appears to be running a scam. He says he is behind ProFlightSimulator, or software with variations on that name. The software can be purchased over the internet, and various claims are made as to it be being the most realistic simulator ever. In reality this software is nothing but a copy of open-source flight simulator FlightGear (fgfs), and an out-of-date verison of that at best. That fact is barely conceded or alluded to on his website. Please also be aware that Dan H Freeman may be an alias. Previously the name Charlie Taylor was used on his website, but was recently removed after I linked that name back to a historical figure in aviation history, Charles E Taylor, the 3rd Wright Brother, whose work ensured the Wright Flyer was able to take to the air. It is my belief that other opensource softwares are being scammed by this same person or organization. A software named Celestia (an opensource astronomy software) has also been copied, and the person mentioned on the website for that copy (John Bayer) also relates to a historical figure in astronomy, Johann Bayer, who created the first complete celestial atlas hundreds of years ago. It is obvious that the names put forward for each software are taken from historical data related to each software, in an attempt to hide who the scammer really is. FlightGear is released under the GPL v2, which allows some concessions to selling the software. However it is my belief, and the belief of a number of people within the FlightGear opensource community, that the conditions of the GPL v2 licence are not being followed completely with the sale and distribution of this software. Hence I would like to request that you consider removing Mr Freemans articles from your website until such time as the validity of his enterprise is determined. However legal Mr Freemans enterprise may or may not be, his ethical and moral standing is without doubt very poor. There are a number of people who recently have attested to being ripped off by this man, so to prevent more people losing money to this scam please consider this request seriously.
