* Erik Hofman -- Monday 13 June 2005 10:29: How would you all feel about making the old Haris' 3d clouds code obsolete by now? Probably a good idea. The old code is broken, unmaintained, and uses nasty binary cloud definition files, while the new code yields much better results (except when flying through clouds). The old code may be more advanced in some respect (and slower :-), but it'll remain in the Attic/ anyway, so if someone wants to pick it up again, fix it, and make it better than the new clouds, go ahead ... m. ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

[Flightgear-devel] New JSBSim Branch
It appears as though JSBSim CVS is in a good state, with the new code, and new directory structure. Notes: 1) No attempt has yet been made to test this with FlightGear - that will take a little bit of work. Things are different: the directory structure, the code, the aircraft config files, etc. 2) I have only attempted to build this under Cygwin and Borland C++BuilderX. 3) Some aircraft, engine, script, etc. files have not been validated against the new config spec. 4) Documentation for the new spec is forthcoming. 5) More information on the converter is pending.

[Flightgear-devel] Re: [PATCH] Re: animation bug
From: Jim Wilson Hi Melchior, There was one thing I forgot to mention. In that animation.diff patch file you also have an unrelated change that does some clamping in the material animation. I understand the logic behind this, but the typical behavior (the way the translationn values are handled further down the line) is the texture wraps at 1.0 and 0.0. IIRC, this behavior is essential in some of the 747 panel stuff. I haven't tested this myself, but thought I'd give you a heads up in case there's a problem lurking in that particular change. Err umm...looks like I got the wrong idea with trans.min/trans.max...mixed up transparency and translation. Throw in transformations and I'm really confused!

The --prop argument is not an XML parser. Just pass the literal
script text as the value, no CDATA munging is needed or legal.
Note also that the script you list above is a noop. It assigns a INIT
function as a local variable but never calls it. If you want to set
the /sim/rendering/clouds3d-cache-size to 4096, what is wrong with:

RE: [Flightgear-devel] YASim turbo/supercharger issues
Some time ago I wrote: Andy Ross: If you do mean this equation then I can certainly live with that. If not, I'll need to put my thinking cap on ... I've updated the graphical representation here: Remind me again which one of these is the real engine data, and what the source is? The only line on this graph that has the dropoff seems to be the polynomial you posted. The others (including the linear one) all have better agreement, qualitatively. We can play with other forms too, like c((x+1)^e - 1) (for some e 1, and with a c that makes the slope through the origin ~ 1). The real data is series 1, but only up to rpm-normalised = 1. For values above 1, it's just a continuation by eye of the data. (See http://www.turbotechnics.com/supercharger/expo.htm Note that max power is at 6500 rpm, and that the supercharger output is nearly flat at 7000 rpm.) I selected y = -0.25x^3 + 0.15x^2 + 1.11x because that had the best fit between 0 and ~ 1.2, which was the region in which I was most interested. This was based on the working assumption that an engine develops rated power at more or less the full supercharger output. At the moment, the equation gives a reasonable match to the known performance. All the other curves are possibilities; that's why they are there :-). I discarded the linear option because of the lack of tail-off, and the other polynomial as a poor fit in the operating region. On further consideration, perhaps the 'ln' solution doesn't tail off quickly enough, although it's a very good fit indeed up to ~1.1. So far as I can see supercharger design and matching it to an engine is as much art as science, and there are many different options. I'm reasonably convinced that the supercharger output should tail off quite sharply after max power, otherwise an engine would just go on developing more and more power at higher and higher rpm until it broke or the supercharger did!. In practice this doesn't happen because the cross section of the inlet is carefully chosen. I'm sure that you can come up with some more alternatives. Let's try them and see if we like them. We seem to have got stuck on this one. I haven't pursued it because the Hurricane model wasn't ready. A beta version is now ready. It, along with the Spitfire and P51D need the attached modification to YASim. The diff provides a supercharger output which varies with engine rpm. It assumes that the normalized supercharger output is ~ 1 when the engine is at the nominated peak-power rpm (normalised). A 'power' equation of the form ((A*(B^x))*(x^C) has been derived empirically from some representative supercharger data. This provides near-linear output over the normal operating range, with fall-off in the over-speed situation. It proves an excellent match to published contemporary figures for the Merlin XX in the Hurricane II, and should also do so for other Merlin variants. It allows the engine to over-speed to 2.5 times the nominated peak-power rpm, and will not break beyond this (although the engine/supercharger probably would in real life!). Unlikely, but allows an unexpected YASim configuration. It also provides an additional control - Boost Control Cutout - which overrides the Boost Control (or wastgate in Yasim). The Spitfire, Hurricane and P51D all had this for use in combat. Finally, the diff corrects a minor bug in the output to the property tree and provides a Boost Gauge input. The beta version of the Hurricane IIB is available here: ftp://abbeytheatre.dyndns.org/fgfs/Hurricane/ There is a tarball (hurricane.tgz) or you can grab all the files individually. The diff is also available there. You WILL need to apply this to run the Hurricane, but so far as I can tell, no other YASim model is adversely affected. Some pictures are here: http://myweb.tiscali.co.uk/vmeazza/FlightGear/HurricaneIIb-3.jpg http://myweb.tiscali.co.uk/vmeazza/FlightGear/HurricaneIIb-4.jpg http://myweb.tiscali.co.uk/vmeazza/FlightGear/HurricaneIIb-5.jpg http://myweb.tiscali.co.uk/vmeazza/FlightGear/HurricaneIIb-6.jpg There remains some more eye-candy to do: nav lights, beam approach marker lamps, realistic rad and oil temperature readings etc. In the meantime I would be grateful for any comments, not least that it all downloads and installs correctly!

I did not answer fully to your solution i only want cache-size=4096
I know if i buy both i get the good answer for the same cost :-)

RE: [Flightgear-devel] OpenAL for CygWin
For Cygwin users, OpenAL needs to be retrieved from this site: ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/openal_cyg.tgz I placed this file in the /usr directory and untar'ed it, though some place it in the /usr/local/ directory tree - which might be more appropriate. Some library and dll files are untar'ed into your bin/ and lib/ subdirectories. Once the files are untar'ed, you must cd to the include/AL/ subdirectory and modify all the files where _WIN32 is present (use grep) and change it to simply WIN32 (that is, remove the underscore). Also, in alc.h you must change the code at top to look like this: #ifdef WIN32 --- CHANGE TO THIS #ifdef _OPENAL32LIB #define ALCAPI __declspec(dllexport) #else #define ALCAPI __declspec(dllimport) #endif #ifdef WIN32 --- CHANGE TO THIS typedef struct ALCdevice_struct ALCdevice; typedef struct ALCcontext_struct ALCcontext; #endif Once these changes are made, you should be able to compile simgear. I'm just in the middle of finally pulling an faq update together (various exams cropped up). I'll put this in. Are there any other issues people want to go in?

This is how it was designed since it's main purpose was sending data to the serial port or over the network. The file option (as it is now) is very useful for generating log files, so it is not possible to do it like that at this time. However, you might want to add line_separatorcarriagereturn/line_separator to see if that helps. If it doesn't work either it would be possible to add a specialized line-separator that performs a fseek(0) just prior to writing the line.

[Flightgear-devel] Completely OT (but aviation related.)
This is not FG related, but I figured I'd do a little show and tell. I've been collecting a few pictures, so I thought I should share them. I may have mentioned in the past that I do a bit of R/C airplane modeling. Last fall I found such a good deal on a ready to fly, kit built Citabria (with engine and radio) that it was impossible to pass it up. It's a beautiful plane and relatively big. It has an 84 wingspan (which is about 2.14 meters.) I flew it Thursday for the first time, and then Saturday in my local club's scale fly-in. I have a couple pictures here: http://www.flightgear.org/~curt/Models/Current/MidwestCitabria/ If you scroll down a bit there's a take off picture (with the tail wheel just coming up) and then two landing pictures (notice the position of the airplane relative to the shadow.) I am also involved with the UMN Aerospace Engineering department building a UAV. I am the airframe assembler/maintainer and chief test pilot. We've done a successful maiden flight of our airframe, but haven't started plugging in any avionics. http://www.flightgear.org/~curt/Models/Construction/Rascal110/ It's not quite a predator or global hawk but it sure is a lot of fun to fly. :-) It's by far the biggest R/C airplane I've flown. Oh, and if that wasn't enough to distract me from my FG duties, I'm also building my own low cost UAV. I have the airframe up and flying. I have the stabalization system installed and tested. My next step is to get the flight computer up and running and begin working on the programming for that. My primary goal is to get a self stable, self navigating airplane up and flying very inexpensively. Beyond that, we'll just have to see what little toys (radio modem? wireless video? etc.?) I can sneak into the family budget and stay under the radar screen. :-) http://www.flightgear.org/~curt/Models/Current/EGN-1/ I do hope at some point to tie in FG to both of these UAV projects. Specifically we want to try out some ideas of using FG as a real time visualization tool for the UAV in flight ... either to draw a 2d live updated instrument panel on the ground station, or to draw a synthetic view of the world from the UAV's perspective or probably some of both. Because the UAV and maintain straight/level flight and can navigate itself (I guess I should say will be able to) flying the airplane could simply be a matter of plunking down new waypoints on a virtual map. This isn't quite as exciting as those posts about people getting their full scale pilots licenses, but it's nice to get away from the computer screen once in a while and do something real even though my feet have to stay firmly on the ground. (Unless I crash, at which point there is a lot of subsequent jumping up and down and vocal noise.) :-) Regards, Curt. -- Curtis Olsonhttp://www.flightgear.org/~curt HumanFIRST Program http://www.humanfirst.umn.edu/ FlightGear Project http://www.flightgear.org Unique text:2f585eeea02e2c79d7b1d8c4963bae2d ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

From: Curtis L. Olson This is not FG related, but I figured I'd do a little show and tell. I've been collecting a few pictures, so I thought I should share them. I may have mentioned in the past that I do a bit of R/C airplane modeling. Last fall I found such a good deal on a ready to fly, kit built Citabria (with engine and radio) that it was impossible to pass it up. It's a beautiful plane and relatively big. It has an 84 wingspan (which is about 2.14 meters.) I flew it Thursday for the first time, and then Saturday in my local club's scale fly-in. I have a couple pictures here: http://www.flightgear.org/~curt/Models/Current/MidwestCitabria/ That is big. Our cat wants me to tell you he volunteers to be a test pilot.

I did it only on that Walrus because it is little (the animation is only driven by the aircraft speed, agl and pitch). It was said that we do not have to make the Hollywood quality movie and i agree. However we could try to find the way which drive to get the best picture, with a combination of specific animations driven by speed, forces,... light processing, and characteristics of materials. It is a pity to see a seaplane taking off, and nothing happen on the sea level , the ground-effect is able to give parameters which could help the design. The new 3D clouds are a good exemple of programming ressource, which could be used to simulate random waves ( i will get god lightnings or rather devil fires, if i continu in that way ). -- Gerard ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
