This is probably because of incompatibillities between gcc and libGLU. You should grab the OpenGL sample implementation ( http://oss.sgi.com/projects/ogl-sample/ ) and build libGLU using gcc. Then you must make sure FlightGear uses the gcc compiled library by setting LD_LIBRARY_PATH before running fgfs: export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib32 Erik ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

[Flightgear-devel] RE: Using gmax models in FG
I've been meeting with increasing frustration trying to complete my C-208 model for
*both* FGFS and FS2002.
I decided to have a go at it in 3DS Max 3 since I have a few friends to help me with
it (and Blender just scares me 8-{). Although I must point out that I'm a total
beginner at modelling so that may have implications!!!
I tried to export a simple model to VRML but that seemed to lose some of the model and
I was beck to square one.
Does anyone know what would be the best format to export the Max model to use it in
FlightGear since I can't go directly to AC3D?
Does it have to go into PPE to name the objects or will it use the 3DS assigned object
names?
Thanks in advance,
Matt.
PS: Is anyone interested in modelling a heli for FlightGear too? Maybe a Schweizer 300
or R22?
I don't know how much work this would be in terms of the FDM/Sim side of things... 80)

[Flightgear-devel] Presentation -- shuttle landing simulator
Hello everyone, Over the last academic year, I have been involved in working with FlightGear and JSBSIM to build a shuttle landing simulator for the Challenger Center at our University. Our project is funded by a grant from the Wolf Aviation Foundation (www.wolf-aviation.org). Jon asked that I send a link to the presentation I recently made to the IEEE Computer Society and the Graduate Council. You may view the presentation here: http://genesis.cs.utc.edu/~wolf/WolfProject%20Version%204.ppt (feel free to use it as you wish). It has some screen shots towards the end of our VR equipment, and the work we've done on the software. We are no where near complete and are hoping for further funding for next year. I had queried the developers list a few weeks ago about a problem we were having with the 3d i-glasses and the stereo buffer. I have resolved that issue. I found that it works as long as FlightGear is not run in "full screen mode". I have to say that being involved in such a project this year has tremendously enhanced my education. I have a new appreciation for open source software and I have learned a lot about the open source community as well. Thank you for all the help you've given me over the past year.

I mean the initialization, setup (clip planes, etc.), and drawing of
the main scene graph. It might not hurt to move more into there
(i.e. lighting and sky), but one step at a time might not be a bad
idea.
My ultimate goal is for fgMainLoop to look something like this:
void
fgMainLoop ()
{
long dt = globals->getElapsedTimeSomeHow();
for (int i = 0; i < globals->getSubsystemCount(); i++)
globals->getSubsystem(i)->update(dt);
}
The main.cxx file should be only a couple of hundred lines long at
most, and should give a good overview of the top-level control flow of
the program. Next, most modules should be moved out of src/Main,
leaving only truly main ones like options.[ch]xx, globals.[ch]xx, and
fgfs.[ch]xx.
All the best,
David

FlightGear should be able to load .3ds and .ase model formats (and any
other format supported by plib.) David Megginson has actually built a
couple models for flightgear and he did a final conversion to ac3d.
I'm guessing that must have been because there were issues with the
plib 3ds/ase loaders David can probably answer that better than I
can.

It *should* use 3ds assigned names, but again, I've never tried this
myself.

Curt.

My one *big* caution on this is to *think* about and pay *attention*
to opengl state management issues. If you don't have a good handle on
the subtleties involved, you could make a real mess of things or
introduce subtle rendering bugs.

Yes, and it also has no '_', which can be quite confusing to people who browse for variables and later try to set these in the XML files or via telnet etc. I brought this up already (8 Feb 2002) and suggested to select a new default font, such as plib's default font, but got no reply. m. ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

For a project here at work I have found a .3ds format bus model and have been able to load it into a plib application. There were some issues though that involved some "massaging" of the model: a) None of the textures that came with the model were powers of 2. Just use gimp/photoshop/xv/imagemagick/etc. to resize the textures to get around that problem. b) One of the textures was misspelled ... also easily fixed. c) Plib loaders typically expect the underlying surface to be "white" and then modulate the texture on top of that. However, many of the surfaces in this model were "black" so the texture came out black. What I did here was export the model as .ase and then popped it up in my favorite editor (in this case emacs) and manually edited the material properties since the ppe material property editor doesn't appear to be implimented. There was a bit of other massaging I had to do for my particular application, but nothing that was plib related.

This is good in theory, but too many un-needed state changes has a performance implication. And, one module cannot control what opengl states another module might change. So this means a module would have to set *every* possible opengl state (i.e. hundreds of them) back to the default/desired values before executing. This is clearly something we don't want to do. plib provides a state management mechanism, but it doesn't do everything we need. There are certain states we need to change that the plib state manager doesn't account for. No matter what we do, we have 'scaling' problems. As the program grows and adds new modules, these modules might set some state that we've never touched before in FlightGear, but having that state changed could cause rendering problems in other modules. This is a mess no matter how you slice it. Things work in flightgear now for several reasons. - A few people have put a ***lot*** of time hunting through code and identifying where various state changes are happening, trying to understand the interrelationships, and resetting various states as needed in the next module or at the end of the module that changed them. - We have tried to use plib's state management mechanism where ever possible. - A fair amount of "trial and error". - Probably some luck. This whole area of the application is "brittle" and there are no good ways at the moment to make it robust and efficient at the same time. *Much* care, caution, and thought is needed by anyone who is going to move code and restructure things in the render loop. > More generally, though, I'm not imagining that order will not matter > -- some subsystems will have to be initialized and updated before > others. Yes, there is a very carefully worked out drawing order between the various modules that do graphical output. All I'm saying is that a ***lot*** of time, effort, code analysis, hairpulling, manual reading, mailing list question asking, etc. has gone into making things work as they are now. I acknowledge that the structure has grown to be a bit of a mess, but anyone who is going to go in and work on cleaning things up needs to be keenly aware of the state management pitfalls. It really can be/is a very difficult problem and several of us have spent a very significant amount of time getting things to work together as they do now. I'd really rather not have to go through that process again after the code gets beautified because, say for instance the moon doesn't blend correctly into the sky anymore, or we can't figure out why the menus have a funny orange tint when the instrument panel is disabled, or the 3rd cloud layer won't draw translucent no matter what we do, or the moon draws correctly, but the terrain textures go berzerk whenever the moon is in the view. These might sound far fetched at first, but they are exactly the sorts of things you end up debugging when you get the state management fouled up. I'm guessing Norman can vouch for me on some of this, and I bet Durk remembers some of the fun we had getting the moon to draw correctly, and then once we got that working, we had issues with lighting and problems drawing other portions of the scene when the correctly drawn moon was in the view. I'm not saying this isn't an area that shouldn't be cleaned up, but I am saying that it needs to be done ***very*** carefully.

[Flightgear-devel] RE: Using gmax models in FG
So what is the consensus on the best route to take getting a 3DS model into FGFS? IIRC, gMax will open .3DS files and I could save and export them to MDL with MakeMDL.exe. I'm not sure if 3DS Max 3 will save to native MDL format... Time permitting, I'll play around with a model this weekend and try out a few ideas. In the meantime, thanks for your help guys. Every plib loader I've tried except AC3D and MDL (a) screws up the geometry, (b) screws up the texture UV mappings [or omits the texture], or (c) both of the above. In some cases, it might be Blender's fault rather than plib's, but AC3D was the path of least resistance. talk21 your FREE portable and private address on the net at http://www.talk21.com ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Got it. Generally I'm pretty good at figuring out what something is and how it
impacts things before I change it...and shy away from the parts that I don't
have the time or ability to figure out. That said, mistakes can happen, but
I'll do my best keep this in order.
Speaking of impact, one thing that has been on my mind is what to do with the
location (aka position) data. Right now just about everything is either
asking the viewer for information or directly accessing the hard coded path to
the property tree ("/position/").
The immediate problem is the viewer doesn't always know the correct
information to give. Currently it is faking it to placate the routines that
are still asking the viewer for things like sea level vectors and "view
position". By "faking it", I mean it is calculating and reporting a "view
position" based on the location of the aircraft that might not actually be the
"real" current view position.
Well you might say, that it is ok for the "view position" to be reported by
the viewer. In some cases I think the values aren't being used in an expected
way. And keep in mind that the "actual" view position is no longer (as in
Tower view) anywhere near the aircraft that is being driven by the FDM.
These problems were evident during testing before I made the viewer fake the data:
1). Somehow the altitude in JSBSim was being increased to the height of the
tower. Thus when you went back to the pilot view the plane was falling from
the sky.
2). Depending on how the view positions are located, and where the tile
boundries are, switch views will trigger tile loading code.
Other problems:
Even with the data that I am faking, there still seems to be a problem with
the lights (both runway and "city" lighting).
1) It appears that when switching tiles the lights jump up.
2) From the tower view the runway lights are way to high.
Solutions?
Unless we want to maintain the tile cache for each view (ack!) then we should
have one location that has nothing to do with "view" for developing the cache.
The view positions, depending on how they are cofigured can either look at
the tile cache or not. As some have noticed you get a big-pale-blue-nothing
depending on how far away your tower is. This will be acceptable for the time
being, or we should print some sort of message that the view isn't going to be
displayed since it is too far away.
As far as the FDM is concerned, nothing from the viewer should be going to the
FDM, directly or indirectly.
Perhaps what we need to do is setup an "fdm location" or "master location"
that can be used as a reference for the construction of all the components in
the scene. The reason I'm bringing this up here in this thread is perhaps it
should be controlled in the FGScene class.
Best,
Jim

Interesting link. Still, I tried the MakeMDl that comes with MSFS 2002 Pro some time ago without success. The *.MDL it writes is too different, it is a new version.

Note that subsequent work in ac3d, even on the tiles that reference this material did not affect my edits.

[Flightgear-devel] Funky tower view
I noticed a few oddities with the tower view after flying a bit. This is the first view: http://rockfish.net/fg/towerviewfunk.jpg You can see the runway lights and cloud layer are misplaced. In the next view, the cloud layer is scooting along. It looks way cool, but shouldn't be happening.

I speculate that the new problem running w/ the MagicCarpet FDM (buried
aircraft) is related to the same problem running w/ the LaRCsim/UIUC FDM
that I have reported. All the while, this has not been a problem running
w/ JSBSim FDM. The problem started around the time that work on the viewer
code began.
Here's my Beech 99 buried:
http://amber.aae.uiuc.edu/~m-selig/tmp/beech.gif
With this aircraft I used Dz_cg = 2.5 ft. This is a LaRCsim variable which
we can set from our code. When I set Dz_cg = 0 ft, then the aircraft is
above the ground. I don't like this solution because it means that I
cannot move the cg relative to the aero reference point anymore (unless I
want to watch the aircraft takeoff from underground). It also required me
to change some of my configuration files (most were using Dz_cg = 0 by
default).
I have not tried to dig deeper. But it must relate to Dz_cg and w/ it
d_cg_rp_body_v (see flight.hxx and ls_generic.h). Getting closer to the
problem might involved this part of code in flight.hxx
// This is based heavily on LaRCsim/ls_generic.h
class FGInterface : public FGSubsystem {
Much has changed here since 0.7.8
I would not have to speculate if I knew what I need to know about c++ ...
~~~
I wonder if you run JSBSim w/ Dz_cg not equal to zero, are the aircraft buried?

Michael

[Flightgear-devel] Heading error in A/P mode
Hi, Have been thinking about that slight error (bias) while in the heading hold mode. seeing similar behaivor with the FMC in the opengc displays. Note that the ailerons are equal displaced up and down when changing the bank angle. Do the FDMs account for the fact that the down aileron creates more drag than the up aileron thereby creating a yawing moment about the z-axis? Regards JW
