Re: [Flightgear-devel] managed view option....
* Syd -- Friday 18 August 2006 02:39: I find the managed view very distracting... only because , since I dont have rudder pedals , I cant get off the ground without spinning like crazy until I get some forward momentum. (Yes , with auto coordination enabled ) That's not a feature (not even a misfeature), but simply a bug. This needs to be fixed, and if it can't, the menu entry will be removed before release. The current implementation works best in not-too-big YASim aircraft. In heavy/very fast aircraft, the accelerations are too big and the heading/pitch change is too strong and abrupt. JSBSim aircraft have the jitter problem on ground. (I thought about disabling ground handling for them completely.) I committed the script anyway, because the reactions on IRC were exclusively positive (with constructive criticism on details -- no bold misfeature comment there). But this doesn't mean it's done. I'd be happy if people could look into it and submit/commit fixes. I'm not an FDM man or physicist, nor a mathematician. But I'll try to improve it. What I'd like to get to is to have it work well on all aircraft without any configuration. This will proabaly be impossible -- we'll eventually need some parameters. But one can dream. :-) I do like the effect during stable flight so , wouldn't a simpler solution be to add a 7th view, the standard cockpit view (same idea as the chase / helicopter view)? I though about that, too. But cycling through view modes is already a pain now. I'd change that if more people prefer that, though. Ive had a similar effect attached to my aircraft for quite a while now , but just movement along the Z axis. Unfortunately, some of the aircraft that have some sort of view control already do often not work well with that mode. Where it works very well, is seafire/spitfire/hurricane/bf109/A10/OV10 (minus jitter)/pa28/pa24/j3cub/... Thats my thoughts anyway, it would be nice to switch modes on the fly. Umm ... you can toggle it in the menu during flight already. View-Toggle Dynamic Cockpit View m. PS: the bo's built-in dynview only works currently when the global one is turned off. This will be fixed, of course. - Using Tomcat but need to do more? Need to support web services, security?

Re: [Flightgear-devel] JSBSim jitter (was: Re: How to turn offmanaged-view?)
Here's a graph that illustrates it: http://members.aon.at/mfranz/jitter.png [20 kB] Command line was $ fgfs --aircraft=OV10_USAFE --airport=krhv --disable-real-weather-fetch and a few settings in local preferences.xml (nothing relevant). SimGear FlightGear from CVS/HEAD, of course. Plotted properties are: /velocities/uBody-fps /accelerations/pilot/y-accel-fps_sec No other part of fgfs messed with them AFAIK, only JSBSim. The only thing that I did was accelerating and braking. Nothing else. (y-axis is fgfs frames, that is, one pair of value output 14 times per second. Yeah, bad fps! :-) m.

[Flightgear-devel] bo105 wihtout pedals
Hi, all people, who want to fly the bo without padels, can change the line 93 dst0=.0065 dst1=.0065/ in bo105.xml to dst0=.35 dst1=-.05/ This adds the throttle input to the pedals, dst0 ist the value at maximum collective and dst1 is the value at minimum collective. The values are not optimized, but should work. Keep in mind, that you loose realism with this, but without pedals it is a good choice. Maik - Using Tomcat but need to do more?

[Flightgear-devel] Making of: jitter.png (Unix)
Maybe someone's interested in one way to make nice live streaming graphs
from fgfs values, like I did for this image here:
http://members.aon.at/mfranz/jitter.png [20 kB]
Used software:
fgfs, awk, kst (http://kst.kde.org/ -- free GPL)
(A) make sure fgfs outputs the relevant data. Logging could certainly be
used for that, but I'm not half as familiar with it as with Nasal, so
I simply put a line like the following in a Nasal file:
settimer(func {
print(PLOT , getprop(/velocities/uBody-fps), ,
getprop(/accelerations/pilot/y-accel-fps_sec));
}, 0);
The actual code looked a bit different, but this should do it. It
outputs lines like the following:
PLOT 0.1429881410812092 0.004077885088460977
(B) create a FIFO and pipe the fgfs output there, filtering out all other
lines, as well as removing the PLOT marker along the way:
$ mkfifo /tmp/fifo
$ fgfs --aircraft=OV10_USAFE 21|awk '/^PLOT /{print $2 $3}' /tmp/fifo
(C) now wait until fgfs is started and the buffer contains enough values. You
can start the OV10 engines in the meantime. Then start kst on the live
stream:
$ kst -y 1 -y 2 -m 1 -n 1000 stdin /tmp/fifo
-y 1 ... use column 1 for the first curve's y-values
-y 2 ... use column 2 for the second curve's y-values
-m 1 ... put both curves in separate graphs
-n 1000 ... always show 1000 values (scrolling contents to the left)
m.
PS: yes, I'm aware of gnuplot :-)

Err ... of course this should be a function that calls itself:
var ubody = props.globals.getNode(/velocities/uBody-fps, 1);
var yaccel = props.globals.getNode(/accelerations/pilot/y-accel-fps_sec, 1);
loop = func {
print(PLOT , ubody.getValue(), , yaccel.getValue());
settimer(loop, 0);

* Buchanan, Stuart -- Friday 18 August 2006 18:45: The obvious next question is, could we display the png in a FG dialog box? No. Why would it have to be an FG dialog box?! Isn't the kst window enough? I'm thinking in terms of a landing tutorial that displays the student's ground track and airspeed at the end... It could be a nice demo for a booth/kiosk. Yes, but only for that. A closer integration with fgfs isn't really desirable. Too OS dependent, and buys you nothing. m. - Using Tomcat but need to do more? Need to support web services, security?

[Flightgear-devel] RTT issue with ATI cards (3d clouds)
Hi, I hope I'm posting to the right ml. I tried to find out what was wrong with ATI cards, and the 3d clouds code. For information, my system is a laptop with an ATI Mobility X700 graphics card. I run a debian testing, with a 2.6.16 home build kernel, and I use the ATI proprietary driver (fglrx) version 8.27.10. I also have a winXP, with which 3d clouds work well. I use flightgear 0.9.10 I did some quick and dirty debugging in the RenderTexture class (using the TestRenderTexture program), and find out, that the reason it doesn't work, is that neither GLX_SGIX_fbconfig, or GLX_SGIX_pbuffer extensions are supported by the ATI GLX implementation : $ glxinfo name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_OML_swap_method, GLX_SGI_make_current_read, GLX_SGIS_multisample, GLX_SGIX_hyperpipe, GLX_SGIX_swap_barrier, GLX_SGIX_fbconfig client glx vendor string: ATI client glx version string: 1.3 client glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_ATI_pixel_format_float, GLX_ATI_render_texture GLX version: 1.2 GLX extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_ARB_multisample OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: MOBILITY RADEON X700 Generic OpenGL version string: 2.0.5946 (8.27.10) OpenGL extensions: [snip] This causes the initialize method of a RenderTexture object to fail quite early on (in _VerifyExtensions()). As a result, the bbcache code returns this during init : bbcache:Initialize failed, RTT not available for 3D clouds So here are a few questions : - I am totally off ? (I have absolutely no background in OpenGl whatsoever). Is there somebody using those ATI driver, who can confirm that those two extensions are not there ? (and that it's not some @#!% driver installation bug on my system) - If this is indeed the problem, should someone file a ticket to ATI to ask for support of those extensions in coming releases of the drivers ? - Or should the 3d clouds code be written to use the FramebufferObject, which seems to be (from what I could gather on the net) a replacement for older off-screen rendering and Rendering To Texture using pbuffers extensions. BTW, this GL_EXT_framebuffer_object is supported by the ATI drivers. Regards, -- Jocelyn Couetdic [EMAIL PROTECTED] - Using Tomcat but need to do more? Need to support web services, security?

Cheers, AJ OK, I have tried this out and identified the problem. It's with the landing gear. Don't use it, and you're OK! ha. ;-) Seriously, it seems to be there only if/when you use the brakes, and further it seems to only be there at initialization. I've tried it from a rolling speed - braking and stopping, and the jitter seemed not as bad. I can reproduce it in the standalone version of JSBSim using a custom script. That way, it will be much easier for me to develop a fix (and I still can't run OpenGL apps pending resolution of my video card problem). I'll be at the AIAA Modeling and Simulation conference in Keystone CO next week. I believe that at least a couple of papers are being presented about landing gear modeling. I may pick up some ideas there. If not, I may have some time to do some debugging using my wife's notebook, if I get up early enough... Jon - Using Tomcat but need to do more?
