RE: [Flightgear-devel] Joystick issues with throttleAxis()
[mailto:[EMAIL PROTECTED] On Behalf Of Ralf Gerlich snip I was just thinking of a more general way of solving the calibration issues than putting it into the configuration files. Regards, Ralf snip I have used systems (PS, PS2, the driver for my Saitek joystick under Windows) which appear to monitor the highest and lowest values that have been seen from a given axis, and assume that these are the extremes of the axis. Obviously when you first start it up, everything is very jittery, but you just need to move all the axes to each extreme and the calibration is set. In fact the PS/PS2 instructions say to move both analogue sticks in circles before using them, I guess this is to effect the calibration. Would it be possible to use this approach for FG?

Mobo suggestions/warnings? Hi, I've been out of the fgfs development loop for an annoyingly long time. At first, I had to adjust to a big drop in free time after (thankfully) finally getting employed. Then I had a video card failure that forced me back to an old card I had lying around which had no 3D acceleration. And then, at the end of July, problems with my motherboard started, and worsened through the month until it became basically unusable by September. I'm secure enough now that I'm shopping to build a new machine. I'm looking at AMD64 motherboards and one of the newer nvidia cards. And what I'm wondering is whether any fgfs developers can speak to building and running fgfs, on linux, on an AMD64 box, and/or with the nv 6600's/6800's etc. I've seen some threads that people are running it on AMD64 OK; but I'm wondering if there are any suggestions, recommendations, or warnings that are worth hearing before I start shelling out the big $ (e.g. mobos you're happy with or had nothing but trouble with). I wanna get back to this stuff. Cheers, -c I build and run FG on an AMD64 3000, on a Gigabyte motherboard (GA-K8VNXP maybe?) in W2K and Linux (FC3, 32 bit). HD is on the SATA port which works seamlessly. Video is an NVidia 5200 (I think) and that is no problem in either OS. I am using the onboard sound, which I now cannot get working with OpenAL under Windows, although it has worked in the past. It works fine in Linux though, and I am moving that way, so I have stopped worrying about that :-) Saitek USB joystick works fine in both OSs (once I had it plugged in while kudzu ran) but the axis numbers are different in Linux and Windows. I will post a patch to the joystick file at some point to fix that one properly. Welcome back. Richard This e-mail has been scanned for Bede Scientific Instruments for all viruses by Star Internet.

[Flightgear-devel] Automated builds on Linux
I am trying to move my main PC over from Windows to Linux (FC3 to be precise). I have a nice tidy script to build and install all of plib, SimGear, FlightGear and Atlas, which works beautifully on Cygwin, but it fails on Linux because it, understandably, needs root privs for the make install sections. How does everyone else here manage this problem? I can't believe everyone rebuilds everything manually, and I know that you don't _have_ to install the packages, but I would like to. I am not a Linux newbie (used it in various forms since 1992), but I am trying to improve my habits. Once I would just have done the entire build as root, but I feel that that is asking for trouble now. Any suggestions?

If the ASCII version is newer than the compiled version, rebuild the compiled version. Sorry, but that sounds dumb. Wouldn't it be a better idea to try to figure out why it is slow in the first place before making all our configuration files non-editable? We really don't have that much XML to parse at startup; if it's really a performance limitation, then it's because we're doing something slow with our XML parsing. Andy Yes, figuring out why it is slow in the first place is a good idea, and I see from later messages that you have done some investigation into this already. But I don't think it is a dumb idea per se. Maybe I didn't elaborate enough: I suggest keeping the editable configuration files, exactly as they are now. When FlightGear starts, and it want to use one of the config/data files, it first looks for a binary (compiled) representation of the file. If it cannot find it, it reads the editable version (slowly), and in the process creates the compiled version and stores it somewhere on disk. If the compiled version exists, the file timestamp is compared with the relevant editable source file. If the compiled version is newer, then it is used, if the compiled version is older than the editable file then the compiled version is recreated as if it didn't exist. I guess that a better description might be a pre-parsed disk based cache of the Airport and Navigation data, and possibly the configuration files. On my Cygwin system here (Athlon 1GHz, 384MB RAM, Windows 2000) CVS from 9am this morning (UK time) startup timings for all defaults are: Elapsed Time (s)Event - 0 Start 3 Splash Screen Up 105 Airport and Nav Data done 252 Aircraft Loaded 258 Sky done 260 Subsystems done 341 Ready to fly So the bulk of the time is in loading the Airport and Nav data, and the aircraft.

RE: [Flightgear-devel] Re: SimGear as shared lib
Alex Romosan wrote: that was exactly the original problem: changes in simgear would involve a full recompilation of flightgear if you use static libraries. and compiling flightgear does take a very long time. now, if you use dynamic libraries, you can make your change in simgear and just go fly right away... Using static or dynamic libs really don't make that much difference when recompiling FlightGear. It's your procedure that makes all the difference. If you do a make install at the top level of simgear (dynamic or static) you are going to reinstall and touch all the simgear header files which will trigger a nearly full recompile of FG. The linking trick someone mentioned is probably the most convenient, but is a little non-standard. Often I just watch which bits are changed in simgear, and only do a make install in those subdirectories. That saves a lot of compiling on the FG side. Also, if you know the headers haven't changed, you can just copy over the .a files to your install location and do a quick relink of FG. (And I should point out that the relink can be quick on the right platform, and can be really slow on other platforms ...) :-) Curt. If you set environment variable INSTALL=/usr/bin/install -p before running configure for SimGear then the simgear libraries keep their date when installed, so the Singear files that FlightGear 'make' looks at only change date if the file has actually changed. Consequently, running make on Flightgear only rebuilds the parts that need to be rebuilt. Saves tens-of-minutes per build on Cygwin.

RE: [Flightgear-devel] Building on Cygwin
I have been building FlightGear in Cygwin since the 0.6 days, but for the past few months I have not been able to get a build to complete. I have had, and have overcome problems with OpenAL in the past, but they seem to have resurfaced. In the absence of any useful information from me (like files it fails on, and error messages), does anyone have a general (but up-to-date) guide to building FlightGear on Cygwin, or even a list of common problems and solutions? I shall gather some hard evidence tonight and post it tomorrow if needed. Thanks, Richard OK, I have made progress past the OpenAL hiccups. First I tried building OpenAL CVS, but that did not appear to work. So I found the OpenAL build by Andy Ross (http://plausible.org/andy/fgfs-mingw-libs.tar.gz) which appears to do the trick.

Actually I don't know even know what it means, It is elevator trim. It will be changed by the altitude and/or speed by pitch autopilots, and can be manually adjusted using 7 and 1 on the numeric keypad (numlock on), but it is slow in manual mode, so hold the button down and wait.

Subject: [Flightgear-devel] fun with SGI images
Erik reminded me to finish a program that I had written a
while ago. It uses
the SGI Image loader/saver that I had written for KDE to
optimize image files,
without changing the image contents. This is done by reducing
unused layers,
using better compression, and not compressing where this
actually generates
smaller images. I let this program now run over the
directories Textures{,.high}/
and Aircraft/ and got this difference:
cvs:223.61 MB
recoded:182.09 MB
--
savings: 41.52 MB
Now, what does it mean? That we should change all rgb(a), and
let every
cvs users sync down 182 MB? Of course, not. But paying a little more
attention to SGI images wouldn't hurt.
m.
Do the texture files _have_ to be in RGB(A) format?
I understand that lossy compression on textures is evil and wrong
(http://www.sjbaker.org/steve/omniv/jpegs_are_evil_too.html), but what about
PNG or even TIFF? These give smaller files with no information loss, and both
support alpha layers properly.
Looking at the plib documentation, it says:
Currently, only SGI format and uncompressed 8 or 24 bit BMP images are
supported - but more formats are planned for the future. Filenames ending with
'.rgb', '.rgba', '.int', '.inta', '.bw' are assumed to be SGI formatted files,
'.bmp' are in Microsoft's BMP format and '.png' are in Portable Network
Graphics format. (http://plib.sourceforge.net/ssg/state.html)
Which first says that PNG is not supported, but then implies that it is. Does
anyone know whether plib will load PNG files as textures?

RE: [Flightgear-devel] alternative terrain engine integration
I think in this case a branch makes a lot of sense, because otherwise the modifications would greatly disturb the main-branch; or I would be forced to hold back a gigantic monolithic patch until codingtesting has finished, which would leave me without version control (and others wouldn't be able to test or contribute). If my memory serves, previous big changes to the codebase have been handled by having a conditional compilation option which switches on the new code (and switches off some old code if needed) and putting all changes in CVS HEAD. This allows people to try it if they want to, and avoids what I understand is the main problem of CVS branches, which is reintegration when it is complete.

-Original Message- From: Jon Berndt Sent: 28 July 2004 3:47 pm To: FlightGear developers discussions Subject: RE: [Flightgear-devel] Taildragger takeoff and landing snip I've heard it described several ways (lift); I think you're pretty close. I don't know if I'd say partial vacuum, though, which might give an exaggerated impression. Thinking of Bernoulli's nozzle example from elementary physics, the flow over the top, curved surface of a wing sees faster airflow, and lower pressure. Integrating the pressure over the lower and upper surfaces of the wing results in a net upward force (assuming steady-state flight). Probably there is a bit of both pushing _and_ pulling going on. If the lower surface of the wing is at a positive alpha, it's not too difficult to think that there is some pushing going on. Well, it would be interesting to get Tony's impression, and of course a physicist will describe this in his own way, too. Jon Well as a physicist (but with no formal aeronautical education), I always think of it as the wing is pushing air down, which causes an equal and opposite force (to quote Newton) of the air pushing the wing up. Hence acrobatic aircraft with symmettrical wings can still fly. The key to wing shape design is to keep the air flow attached to both the upper and lower surface so that you can change the direction of airflow. Once the flow detaches (a stall), you are not pushing the air down any more, so it isn't pushing you up.

[Flightgear-devel] Cygwin and OpenAL
Since the addition of OpenAL I have been having sporadic success building FlightGear on Win2K and Cygwin, but I think I now have is sussed. I first tried installing the Creative OpenAL SDK, but that didn't appear to help. I installed Norman's OpenAL stuff, and things got better, I eventually got a fgfs.exe, but it would segfault when I ran it. I tracked this down to having a vintage version (1.1.something, probably 12 months old) of cygwin installed, an update later and things were good. At some point (I should have kept notes) I fixed a missing DLL entry point problem by removing the Creative SDK. Then it broke again, so I rummaged through the list archives, and found the message from David Luff on 28 April 2004 giving a list of libs to put in Makefile.am, and I noticed that the list of libs in that email does not include alut, yet the Makefiles in my simgear and flightgear trees did include alut. I removed alut from the list of OpenAL libs and everything is working again. Does this mean that alut is not needed on cygwin systems? I certainly cannot find an alut library anywhere, only a header file. Richard Bytheway ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

I wasn't even trying to think about the problem so if anyone else had the same ideas at about 10:30pm UK time, I apologise for telepathic theft of your ideas. 1) For each wheel (or group of wheels), we keep a coefficient of friction in the rolling direction and a coefficient of friction perpendicular to this. 2) The vertical force on the wheel is multiplied by the two coefficients to get a maximum force in each direction that the wheel will absorb before it starts to move, that is the drag. 3) The horizontal force on the wheel is resolved into two components, one parallel to the rolling direction and one perpendicular to it. 4) Each horizontal force component is modified according to the following rules: If it is less than or equal to the drag in the same direction calculated in step 2 then it is set to 0. If it is greater than the drag calculated in step 2, then it is reduced by the drag. 5) The modified horizontal forces are recombined to get a force which can be used to accelerate the aircraft. I suggest that the coefficients of friction stored are for a tyre at correct pressure on dry tarmac, and then the could be modified according to ground type and tyre condition automatically. For instance grass will increase the rolling coefficient, but decrease the perpendicular coefficient. Additionally, we may want to include a mechanism to store coefficients for different ground types. Unfortunately I don't have the skill or time to implement this at the moment, but I think that some others are working on the problem, so I offer the ideas to the group as brain fodder.

Thanks Vivian Meazza I have a memory from years back of being told that the reason the Spitfire had such a distinctive sound was that the propellor tips _were_ supersonic. Maybe it was just heresay. Richard I think it is possible that the propeller tips went supersonic in the corners of the flight envelope of some of the later versions. However, the math seems to show that in most circumstances they were not. It seems unlikely that this could explain the distinctive sound when heard from the ground. Here are some calculations on propeller rpm. The propeller the tip speed should be as high as possible with the only limitation being that the tip should not get into the region of aerodynamic compressibility. Typically a figure of Mach 0.85 is used as the magic number that should not be exceeded. (This makes some allowance for the speed increase as the air passes over the aerofoil curved surface and the increase in air velocity caused by the propeller operation.) If we take 8000 ft as the operating altitude then Mach 1 = 1085 ft/sec (approx) Assuming that the forward velocity of the aircraft is 300 mph = 440 ft/sec Then the maximum rotational velocity may be calculated by Pythagoras: Max Rotational Velocity = ((M *1085)^2 - (V)^2)^0.5 where M is the designed Mach Number (0.85) and V is the aircraft forward velocity = ((0.85*1085)^2 -(440)^2)^0.5 = 810.52 ft/sec RPM at Max rotational velocity is given by: RPM = Max rotational velocity*60/(PI * D) Where D is the propeller diameter (ft) = 810.52*60/(PI * 10.75) = 1439.98 rpm At 3000 rpm the propeller rpm is 1431 rpm, but the Merlin only did this when the throttle was through the gate, and the Boost Control Valve Cutout was operated. This was allowed for 5 minutes. We can calculate the Max Rotational Velocity @ 1431 rpm Max rotational velocity (PI * D) = (RPM/60) * (PI * D) = (1431/60) * (PI * 10.75) = 805 ft/sec We can also calculate the Mach Number (M) of the tip by rearranging and substituting M = ((805^2+440^2)^0.5)/1085 = 0.8459 I hope that all the maths are correct. I think all this shows that under normal operating conditions, and observing the normal operating limit of 2850 rpm, it is unlikely that the propeller tips would exceed M1.

Those are mostly 256x256 each, I think, and so they use a *lot* of texture memory (the Attitude Indicator alone has four of them) -- it's not enough to hit my 32MB GeForce2Go, but still, a lot. Also, I'm not starting at KSFO -- the structures around there also use up a lot of texture memory. If you have only 16MB of texture memory on your card, you'll probably be in trouble.

Also how much more computing power will be required for what ever extra detail may be involved.A 3D modeller would not even think of modeling the insides of the engine or every rivit in the aircraft for the obvious reason that the model would bring the computer to a halt.I am just wondering if this in its own way is not doing the same thing. Anyway the one question I would realy like answered is what is wrong with the current system.If the answer is nothing then why change. Famous Saying if it an't broke don't fix it Disclaimer: I don't fully understand the current autopilot system, but I think I get the gist of the new proposal. As I understand it, the proposal is to rework the autopilot so that it is configurable within the XML for each aircraft, rather than being buried in the C++ code. To do this, there is a need for a controller that is XML configurable, which can have inputs, outputs and magic numbers associated either with entries in the property tree, or fixed in the XML. It makes sense to implement as few types of controller as possible, and make them as flexible as possible. A PID controller does everything we need for simple controllers (wing leveller by aileron, or speed by throttle for instance), and can be stacked (or cascaded) for more complex situations. It can also have the I and/or D components set to 0 if you want a P, PI or PD only controller. We might also need some simple auxiliary units, such as a summer and a limiter, although these could probably be combined into a summer which has the ability to clip the output. There is nothing in the proposal that would make use of this system compulsory. The current system isn't broken, it just isn't as easy to set up, or as flexible as a system could be.

When the wings are level and the actuator (roll trim) stays out of saturation, this PI controller works great.

RE: [Flightgear-devel] Electrical system work..
And actually, you get quite a variety of ammeter variation depending on if you are running battery only, have an alternater fail, have the alternator working, have the engine running, and or have a lot of devices and lights going. This change in current must be due to the voltage on the supply changing, thus we actually need to know the resistance of each load, and the output voltage of each source. Then the current on the system is then calculated from Ohm's Law, V=IR, or in this case I=V/R. You probably need to know internal resistances of each power source as well to do a proper model, but that might be a step too far in the first instance.

RE: [Flightgear-devel] Re: I am new here/ helicopter flight model
From what I know (which is almost nothing) the simple answer is: Carefully. I had a neighbour who built model aircraft for a hobby, and would produce a top notch aeroplane each winter. Having built a 12ft wingspan monster (with radio controlled parachutist), he built a helicopter, which took 18 months rather than the usual 4-6 months. On the first test flight he got it 6 inches off the ground and knew he would crash it very soon, so sold it without ever flying it again.

RE: [Flightgear-devel] New rendering propery added
Hi, In a private discussion with Frederic Bouvier about the framerate hit of the new static scenery created by Frederic (which I still think is a fantastic job by the way) we came to the conclusion it would be a good idea to have a realism property set to adjust the level of realism for the scenery rendering. As of now I've added the /sim/rendering/realism property which could be used to control the realism level. The two things discussed so far are the bridges and the Bank of America building which could be generated at a much lower vertex count by using some texture tricks but at the cost of realism. Frederic suggested to add a LOD to both to controll the looks of these objects by applying textures at a large distance and vertex objects at short distance. By checking for the realism property it would be possible to prevent the LOD check for machines that can't handle these large amounts of vertices (like my O2) and show the textured object all the way. Erik Is this a boolean property, or a sliding scale? I think the latter (0-1 or 0-10) would be the better option since you could define points along the scale when chages are made. Such as random objects only when realism5, high poly count builds when 8, nothing but scenery and runways when 0.1 Richard ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Yes, CVS does send stuff up the line, and yes on a 56K modem this does happen at only 33.6K (best case). However, it only happens once.

I'm afraid of getting expelled from this list someday for bringing this subject up so often, but I haven't received an answer yet. My problem is that updating the basepackage via a dialup-connection and CVS seems almost impossible to me. First, the cvs client is obviously _sending_ every one of the local files to the server before updating my local copy. See this (partial) result of cvs -t update -APd: cvs update: notice: main loop with CVSROOT=:pserver:[EMAIL PROTECTED]:/var/cvs/FlightGear-0.9 - rename(CVS/Entries.Backup,CVS/Entries) - unlink(CVS/Entries.Log) - Sending file `AtlasPalette' to server - Sending file `ChangeLog' to server - Sending file `Thanks' to server - Sending file `joysticks.xml' to server - Sending file `keyboard.xml' to server - Sending file `large.sky' to server - Sending file `materials.dtd' to server ... Sending default.apt.gz alone kept my modem busy for about 5 minutes. Is there something wrong with my cvs-client or is this the normal behavior? Second, this method of updating seems a waste of bandwidth to me, as the bigger part of all the files transmitted to and from the server are likely not to have changed since the last update. Curt, could you therefore enable rsync-access to the basepackage at flightgear.org?

[OT] Cygwin directory structure - was RE: [Flightgear-devel] Re:Help:FATAL:ac_to_gl:Unrecognisedtokenunder CYGWIN
The mapping between how windows sees directories, and how cygwin sees directories is odd, but not that complicated. I will use marks to enclose commands and paths, when you type them, do not type the . What windows sees as H:\cygwin is / under cygwin. Thus H:\cygwin\home is equivalent to /home in cygwin. Does that make sense? Note that windows uses \ to separate directories, whereas cygwin (and most/all other Unix like systems) use / Getting this wrong will stop things working. I think the key here is to understand that the directory you start in is not the root directory. When you first start a cygwin shell, you are in your home directory, this is probably /home/innis (presuming your username is innis), which windows sees as H:\cygwin\home\innis. This may also be represented as ~ when in cygwin, since ~ is standard Unix shorthand for the current user's home directory. Note that ~ is not the root directory, / is. To move around the directory tree in cygwin, use the cd command. cd on its own will take you back to your home directory, this is equivalent to cd ~ or cd /home/innis (without the quotes of course) To get to the Flightgear base directory, use cd /usr/local/Flightgear You can also use .. to refer to the parent directory, and . to refer to the current directory, thus when in your home directory, cd .. will take you up one level to /home Hope that helps, Richard -Original Message- From: Innis Cunningham [mailto:[EMAIL PROTECTED] Sent: 02 July 2003 9:04 am To: [EMAIL PROTECTED] Subject: Re: [Flightgear-devel] Re: Help:FATAL:ac_to_gl:Unrecognisedtokenunder CYGWIN Fred every time I run a line like you say below in cygwin bash shell I get unable to find directory.It is I guess because in the shell it thinks HOME is the root directory instead of cygwin.Thus directories like usr,ect,bin and the like I can not cd into because they are on the same level as HOME.To try and make it clearer.On my H drive I have a folder named cygwin.Inside that I have folders bin,etc,home,lib,tmp,usr and var.In the home branch which the bash shell has me locked is all the build files for FG.In the usr branch under usr/local/flightgear is the bin and data folders for running FG.The thing is I cannot get from the home branch to the usr branch in the bash shell.If you could explain how to do that, that would be great.Hope this makes some sence to you.

RE: [Flightgear-devel] Re: how to fix joystick config files
Julian Foad [EMAIL PROTECTED] said: I think what you are proposing is better than the way it is now. However, it should be easy to make it perfect. In your proposal, each binding specifies an amount of change per step, and you fix the number of steps per second (which previously was varying, being faster on faster machines). The objections are that the smoothness of control operation is limited by this fixed step rate. Instead of that, have the binding specify the amount of change PER SECOND (i.e. the rate of change), and allow the number of steps per second to vary with machine power and load. At each step, the new value is calculated so that the control is moving at the specified rate: value += rate * delta_t. That would make the rate of change well defined, but the smoothness would be better on faster machines. I f Jim wants to control the update frequency he can then do so very easily. But the important thing to do first is to define the rate of change rather than the amount per undefined time step. This is a sounds good. But it is possible that some controls might be better off sacrificing speed for higher resolution step sizes on certain systems (e.g. trim controls). Then again we could pick and chose which controls use the per second method and which use the fixed steps (in other words, support both). As I mentioned earlier...controlling the update frequency doesn't seem necessary to me right now. Best, Jim To get both fine step and constant rate modes, could it be implemented something like the standard PC keyboard interface? That is you get a single click if you press the button for less than 0.2 second or so, and only after that does it go into bananas per second mode.

RE: [Flightgear-devel] Shadows and joysticks
I use a Saitek Cyborg 3D Rumble Force, and it is better than any other PC joystick I have used (not that many in the comparison group though, and no MS products). OK, so the rumble effect doesn't get used in FG, but it is a very nice indication of WOW in IL2, and if plib ever gets to support force feedback devices, it would be nice in FG too. Richard -Original Message- From: Lawrence Manning [mailto:[EMAIL PROTECTED] Sent: 23 June 2003 9:57 pm To: [EMAIL PROTECTED] Subject: [Flightgear-devel] Shadows and joysticks First post to this list... been playing with fg for a few weeks now and I have to say I'm very impressed. It runs super on my 2ghz AMD linux box with Geforce 4 gfx and the Nvidia drivers. Ok, questions... First of all, are there any plans to implement shadows? A shadow of the aircraft over the ground would obviously make judging the height visually much easier, and add to the realism. Of course, the ultimate is to make it so mountains and the scenery itself can cast shadows, even into the cockpit of the 'plane! But a good start would be aircraft shadows. I haven't a clue how feasable this is, and the question has probably been asked many times before, but here's me asking anyway. The second question is to ask if anyone can recommend a good joystick for flightgear use? The only thing it will be used for is fg. Not after anything too flashy; just needs the additional rudder and throttle controls. A friend recommened one of the Microsoft sticks, so I'm inclined to go for that (say all you like about MS, but they make good hardware! I love my MS optical mouse). I haven't bought a joystick since they used 9 pin D-type connectors and did 4 digital directions and a firebutton, so any guidance anyone can give would be great. Anyway, thanks for the superb software. :) I look forward to future versions and helping in any way I can.

Allegedly, hot-air balloons used to fly underneath the bridge occasionally, but that must have been before my time. More recently all flying under the bridge has been banned.

RE: [Flightgear-devel] Re: P-51D 3d Model and help request
As a pay-by-the-minute modem user, I would prefer not to have 200MB of data dumped into the base package CVS if possible. The cheapest my connection gets is £0.48 per hour. 200MB is about 20 hours of download time, thus costs about £10 (US$16 or so), and my phone line is busy for a day. I think that splitting the base package into two branches/repositories would work best, one for what is needed at runtime, and one for the source files (everything else). I am not in favour of separate branches for different aircraft, or even one new branch for optional aircraft, since CVS is used by people who want the latest features, thus new features should appear in CVS, not elsewhere. People who want to play with the source files can then take the decision to download however many MB of data, but for those of us on modems with no graphical abilities can avoid the pain. For the runtime texture files, would is be possible to switch to a format with lossless compression, such as png? Whilst it does not save on video card memory usage, it has a minor (negligible) benefit for hard disk space, but could have a significant benefit on download times. Richard m. :-) And I have another 200MB of xcf files for hi-res C172-S Panel :o). IMHO one and only solution is to make new CVS branch for it.
