Re: [Flightgear-devel] Final 2.6.0 Release Preparations

This new version contains many exciting new features, enhancements and bugfixes. Major improvements from v2.4.0 include reduced AI aircraft load times, easier graphics tuning, more sophisticated AI aircraft and improved usability. Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in Universities and for interactive exhibits in museums. FlightGear features more than 400 aircraft, a worldwide scenery database, detailed sky modelling, a flexible and open aircraft modelling system, varied networking options, multiple display support, and an open architecture. Best of all, it is open-source so no company controls development. A more positive angle for the last sentence would sound better. Something like 'Best of all, it is open-source so the developers control the direction of the project'. -- James (Jay) Treacy tre...@debian.org -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
Re: [Flightgear-devel] Realistic GPS position

Ideally, the filter would support a tuneable precision parameter, so I can model selective availability, WAAS and poor reception (crudely) by adjusting the precision input. How simple do you want? Didn't bother with SA but easy to add. A = 2.7x10^-5 + (NW * 10^-4) + (BC * 2.7*10^-4) A1 = A A2 = A / (cos(tlat) + .0001) lat = tlat + A1 * sin(min*21) lon = tlon + A2 * sin(min*27) if (lat 90) lat = 180 - lat; if (lat -90) lat = -180 + lat; if (lon 180) lon = -360 + lon; if (lon -180) lon = 360 - lon; tlat and tlon are true lat and lon angles are in degrees min = time in minutes NW = 0, except 1 when no WAAS BC = 0, except 1 when bad conditions Assumes a pure sinusoid with a frequency of about 15 min. This would nominally be a factor of 24 (for angle in degrees) but 21 and 27 were used so lat and lon changes are out of phase. The amplitude of the noise is based on 3m accuracy at the equator (360 deg / 4x10^7m circumference = 2.7x10^-5). When WAAS is not present, the amplitude is increased to 15m. When bad conditions are present the amplitude goes to 33m at best (number is just a guess). The amplitude for the longitude change is then increased as you get closer to the poles. Safeguard added to prevent things things from blowing up if you are manage to hit a pole. Finally, if the lat, lon are greater than 90, 180 fix them. -- James Treacy tre...@debian.org -- Come build with us!

Re: [Flightgear-devel] Proposed fix for an obscure tile loading/caching bug
It is not clear to me that age is the best metric to use in all cases. The tile that is the farthest from your current location would also be a good candidate for removal. Since the current algorithm works in most cases, a less intrusive solution than messsing with how/when timestamps are applied would be to, when the oldest tile has a timestamp of zero, remove the tile that is farthest from your current position. -- James Treacy [EMAIL PROTECTED] - 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
[Flightgear-devel] Graphics cards for flightgear
I am going to upgrade my system soon (my current system is so outdated I can't use flightgear well on it). Even cheap recent cpu's are more than capable of handling desktop tasks but what about graphics? I don't need much power in a graphics card, except for flightgear, and it is not clear how much I need for that. The flightgear web site and wiki mention that any recent graphics card should be fine for flightgear. Is that really the case if you want to have all the bells and whistles turned on and have a decent frame rate? I'm talking about shadows, fires, etc, while flying one of the larger planes (lots of triangles and textures). For example, I'd love to get away with a Radeon 3450 (low power, fanless and only about $50) but will get something more powerful if needed. On to the questions: What are the hardware requirements for flightgear at its most demanding? Are there any features in development that will require more powerful graphics? *MOST IMPORTANT* What is the cpu and graphics card in your system and what frame rates do you get in flightgear? Also give your OS. Hopefully we'll get enough information from this thread so I can update the wiki with something more useful. -- A: Because it messes up the order in which people normally read text.
