[Flightgear-devel] OT: Laptop! - Frame Rate
Hi, Got my Laptop, installed Linux, installed the latest ATI driver (although only running SuSe's 9.1 updated kernel - 2.6.5) I'm running fgl_glxgears (probably not an unbiased test given it's ATIs code I would guess). I'm getting 490fps - looks good. I'm going to investigate exactly what ATI provide now. I started off with their packages this morning, had to do a few mods to get it compiling... then noticed that SuSe are providing a customised version that runs out of the box... now using that. I'll let you know fg frames rates in the short term future. Regards, Chris. ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
OT: Re: [Flightgear-devel] Re: Laptop
Should probably end this thread now, the topic is wondering from being in the slightest flightgear related. Bad form to reply to my own post. I have decided not to go with an nvidia based system because the performance seems that much worse compared to the 9700 based ati graphics in some laptops. For anyone interested, on monday I intend to get the 2.2kg Razor from http://www.savrow.com/site/razor.html with a 7200rpm 60gb drive, rather than 5400rpm 80gb drive. Performance is better from the 60gb drive and it is for the same price. I'm just debating whether it's okay to opt for the 80gb drive, I'm not convinced though - all my drives in my desktop have faster seek times and the 60gb one is the only drive available that seems to offer similar performance. Reading the manufacturers web site it is also based on newer technologies and consumes equal or less power (based on the shorter times required for reads).

Re: [Flightgear-devel] Re: Laptop
You specifically need to decide whether weight is a factor for you: (a) a desk top replacement, will weigh about 8 lb ... a luggable (b) a lightweight powersaver, will weigh about 4 lb ... no gaming conversion 2.2lbs = 1kg, so I guess I'm talking a 'not quite desktop replacement at ~7lbs.' My personal computer at the moment is a 1GHz P3 with 512MB Ram and 32mb geforce 2mx graphics. For me a processor which has much more cache (4-8 times as I can't remember how much L2 cache a p3 100mhz fsb has). 4x the bus speed, and 1.7x the clock speed can't be that bad. I'm not convinced processing power is the be all and end all any longer... in my mind that sounds fast enough for a processor. I'm under the impression that the graphics is the most important thing, I would welcome critique as to where system limitations occur. My laptop has the 9600, can't help you on the support level for 9700. If you visit the ATI discussion boards, you'll find that ATI have been playing marketing name games with the recently released chip designs. I have emailed ati, no response as yet. I will look at these discussion boards. What I don't understand is they have one document indicating that everything above radeon is supported and another saying only certain specific chipsets are supported. Are the problems you're experiencing with the drivers only experience on a 64 bit system? What are the power saving features like for this driver? Can you configure anything worthwhile?

[Flightgear-devel] Laptop
Good afternoon, I've been 'away' for a while - no internet connection for two months, didn't really miss it. I now have ~5000 emails to catch up with, luckily most of those are mailing list related. I'm going to buy a laptop very soon (pay day approaches). I wondered if anyone had a Rock Pegasus Ti with a 1.7GHz Pentium -M ( new core type) and 1GB of memory and a 7200rpm HDD. This is what I'm considering buying at the moment. Can anyone recommend a similarly specificed machine for less, looking equally good? Price all in looks about 1500 gbp at the moment. Points to consider are weight and battery life - I'm estimating about 3-4 hrs on battery life for this model running at full pelt.

This is what I'm considering buying at the moment. snip I've never bought a loptop for myself, but when I look, the first thing I try to figure out is what video subsystem comes with it and how much video ram. I know I can get GeForce based laptops to run well. I assume that ATI based laptops also work well, especially with windows. But if you find some other random video chipset that you've never heard of before, you might do well to skip it ... at least if you plan to do any sort of 3d graphics on your laptop. I plan to do a lot of 3d graphics (almost the precise reason for buying it - to allow me more time for programming, outside of the home). ATI 9700 M11 128MB ram. ATI's driver says they support upto the 9600, so I will email them to confirm whether they will support the 9700 (they support the desktop version). forgot to post a link earlier http://www.rockdirect.com/rockshop/shophome.php?itemprcd=PTI-1.7 ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Re: [Flightgear-devel] Re: RFC: Concorde
Don't want to rain on your parade, but someone donated a Concorde already. There was just nobody who wanted to reduce the *many* vertices and re-apply the textures afterwards. Blender is quite good at reducing, but it would still mean a lot of work. If you want to continue to work on your Concorde then you might at least want to use some parts of this: http://members.aon.at/mfranz/concorde.tar.gz (1 MB) http://members.aon.at/mfranz/concorde.jpg (41 kB) heh, I must have missed that one. It looks better than mine. I wasn't really all that serious as it only took 2 hours and it wasn't done on any of the tools used by people on this list. I was going to pick it up in blender and finish it, but I won't bother now. My intention was to improve my surfacing skills... I did, but it wasn't much of a challenge. I've been looking at other things to do with plib (offscreen rendering), my time is limited though... Hope to be more helpful when I get a laptop. I got hold of the paper referred to from AIAA in the landing gear simgear file, it's a shame it doesn't have more details - it looks as if it could have been of use with the current u/c problem in simgear (i.e. it stays still in a crosswind but not by setting the velocity to zero).

Re: [Flightgear-devel] Re: Helicopter Animations
* Jim Wilson -- Wednesday 28 April 2004 06:17: Probably the blades are doing a lot more than just spinning around the hub. Indeed (I knew this), but for a slave machine and potentially multiplayer I do not believe it is sensible to do any more than get the propeller spinning and when it reaches full speed display a disc discolouration. Yes, indeed. Each blade consists of 5 segments which are animated in a way ... the bo105 uses 101 animations, with more to come. sample frequency. The rotor may look like standing still or spinning slowly, even in the wrong direction. That's hard (or rather impossible?) to avoid. A fair point which whistled by me... I guess I must have been immersed in the flightgear environment. I would guess once the rotor exceeds the framerate you'll have problems? Not a problem to consider after a 12 hour day at work...

[Flightgear-devel] Helicopter Animations
I wrote a patch to get simple helicopter animations to work on a slave machine. I didn't look into the source too much at first - I wrote most of the patch on the Linux Developer expo day. I now realise I missed something. I think the ExternalNet.cxx file is used when the native protocol is used, this never calls the required routine to see the animations on the other computer/fgfs2. If I use the --native-ctrls I do see the animations, but get no position updates for the fdm (because the netfdm isn't used). from the looks of this we'd need to use one protocol to move the heli and another to animate it. The only problem is that both call the same function at one point and waste cpu time - because it's really only needed the once. Anyway all that aside I'm noticing another problem now that I got it partially working. it's like watching an old black and white movie - wheels (props) are almost spinning backward because the camera (hz) is not large enough. I have Hz set to 30. I can't help but think here, why do we need to handle the rotation by a position rather than by rpm? What happens with fixed wing propellers in this situation?

Re: [Flightgear-devel] Jsbsim trim
Andy, It's a misfeature in the gear modelling. YASim has pretty much the same behavior. Both FDMs model gear force as a function of skidding velocity, which is fine for dynamic solutions. But a gear that is planted on the ground is capable of holding an aircraft at zero velocity, which doesn't work with the current FDMs -- zero velocity produces zero force. It sounds as if we were to tell the weather system to model a significantly strong hurricane that we would see the parked aircraft swept away. What I'm leading up to is that if this effect is happening whilst stationary, it's probably making the a/c more difficult to control on takeoff than it really is. That is if it still happens when the a/c is rolling. Just thinking about it... When the a/c is stationary the force on the wheels is the aircraft weight less the lift due to airflow over the lifting surfaces (a function of wind). As the a/c progresses on takeoff the above effect should change as the a/c gains speed. If it's having an effect straight away does it not need offsetting until a certain airspeed is reached (due to the weather system or a/c movement)? What's needed is code that, at low speeds, uses a spring model for gear force based on the distance in position from where the gear is stopped. Which sounds easy, but in practice is awfully hard. I've gotten started on this several times, and never produced useful code. So you're suggesting that the a/c mass, a friction coefficient dependent on weather condition and landing surface and tyre contact area are combined to provide a more realistic static case? If I've interpreted you correctly... what was the problem encountered? Chris. ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

I'm looking forward to the report. :-) Oooh yes, from several announcements I have the impresseion that the FlightGear setup in the Wasp is really the main attraction of the whole show ! Well I found several interesting things, the .org stand was worth a visit. Flightgear occupied most of the time though. The commercial companies upstairs were having a good effort, I never quite listened to any full presentations although I made an effort once (they were very good for visiting businesses, not quite for the individual though). The ladies were out and about (Rackspace?) and also on a few stalls promoting their products (I did ask what, but have since forgotten), that made a pleasant change from males dominating the environment. I had a good time at a salsa club one evening and a few beers with the guys on both evenings. I think we all agreed after the success it was we're looking forward to next year/ the next time!

Re: [Flightgear-devel] Spitfire Hurricane manuals
Sorry I've not had the opportunity to reply to this earlier (holiday away on business). I was responsible for the spitfire model. Unfortunately the commitments of work and trying to have a social life didn't agree with continuing it. I hope to at some stage get some very detailed pictures on a later model spitfire. The model is based on a mkXIV and I have collected many pictures of the spit whilst I modelled it. These wouldn't be of much use in it's current state as all the geometry that's really missing is some ducts. Under wing and centre fuse. I never got as far as putting it into flightgear... but it's GPL'd from my standpoint. I think Jon had some data for the flight model. It is a hope of mine to have a Concorde model. However I find blender a bit backwards compared to what's available at work, and I'm not getting anymore free time than I was before. At work we have a flying spitfire and typhoon. I'm trying to get access to these so I can provide more detailed information on them e.g. photos etc. We also have the last production Concorde (lucky eh..). From my point of view I think the spitfire is a spectacular plane to watch, and I find the rumours about the design origin most interesting. I'll probably see some of you at the expo...thought it'd be a nice break from work.
