That's odd. I would hav expected the compiler should be able to find the 
headers for TerraGear also.

I haven't used terragear for ages but you might want to add 
-I to you CFLAGS settings to point the compiler 
directly to the location where it can find the header files.

I think most of the sims will show some "simple ideas" like a (virtual) flight 
with 
the Wright Flyer near Etten-Leur (first motorised flight in the Netherlands 
happened there) or some historic scenery. So, probably it would be nice if we 

could come up with something different, just to stand out of the crowd. I'll 
try 

to come up with something in the upcoming weeks...
 
Another "milestone" is the 90th anniversary of KLM airlines (founded 7 oct. 
1919).
Maybey we can gather a fleet with all (or atleast most of) the aircraft ever
operated by KLM? We do have quite a lot of them in FG, just need some more
liveries...

Re: [Flightgear-devel] Running FGFS 1st time - Initializing Subsystems then "Debug Assertion Failed"

[Randall Green]

Jon,

Thanks for the reply. I did rebuild FlightGear. When it got the error next I 
clicked
on the Debugger and it brought up the latest string_utilities.h, so it was 
using it.
Someone said that the JSBSim was ahead in development of FlightGear. Is it
possible to do a CVS download of just that?
Also, the only aircraft I  was able to operate so far using Yasim is the C130.
I tried the Cessna 310 , the pa24-250, the SenecaII, and the beech1900d but
all failed. Some had these QNaN matrixes flying by in the cmd window, others
say "unexpected tag 'fdm_config' found in yasim aircraft description. Does 
anybody
know how to fix this? I really need a small prop plane for my experiment.

Thanks,
Randy Green

Re: [Flightgear-devel] Shaders (Mac, nVidia 7300GT, latest CVS)

[Nicolas Quijano]

Strange colors on windows with ATI GPU, but here dominating color is red in
the crop shader.
I slightly modified the effects file and rendering gui to be able to enable
them one at a time.
both landmass and crop suffer from that, and it's triggered by camera
movement.

Unrelated comments :
Might want to look in at disabling fixed function lighting when doing per
pixel lighting, and tweak blending and alpha settings, first to avoid
wasting gpu cycles on unneeded settings, like lighting when doing per pixel.
but also to prevent side effects from fixed function state.

Also, I was once told that stuff like a = b = c should be avoided : there is
absolutely no guarantee it will be processed correctly, or in the order you
think it would. GLSL is definitely not C :)
Seems to work, but it's a dangerous slope if you want portability to rely on
C side effects in GLSL.
Common and oft repeated wisdom is if you develop on nvidia, you debug on ATI
(or 3Dlabs) and if it runs there, it should run everywhere : nvidia seems to
be the laxest of the GLSL spec interpretations (they all divert from the
spec where they feel like it, except maybe 3dlabs who, well, created the
specs)

Comments inside code lines are forbidden by the specs (stuff like some_code
/*comment*/; is not compliant, but some_code; /*comment*/ is) : either by
itself on a line, or after all code on a line, after the;

Water shader does work beautifully, albeit the geometry seams are very
visible. I seem to recall that wasn't the case with the first version
committed, I'll have to re-check.

Thanks for all the hard work,
Cheers,
Nic

Thats the CVS version, I am still downloading the data from the CVS (a lot

hi james,

this is not at all how it should look like. i believe that either something is 
wrong with lighting values in gl_FrontLightModelProduct / gl_LightSource[0] 
or smoothstep() does not work correctly on your system.

i'm working on improving the shaders. i'll try to make a shader without 
smoothstep for you to check.

the problem could also be mac-specific? did someone else notice strange colors 
with the shaders on os x?

Re: [Flightgear-devel] MP Protocol - aircraft orientation

[Marco Lecora]

Dear George,thank you for your reply. I have downloaded the application you 
suggested me but I did not find what I need.In my scenario I have a simulation 
platform the determines orientation, position and velocities of several 
aircrafts; what I want to do is to send this information to a fgear multiplayer 
server by means of Flight Gear Multiplayer Protocol.
I tried to use (by porting them into C# code) the following code snippets (from 
multiplay.cxx and multiplaymgr.cxx):
// multiplay.cxx -- 
   // The quaternion rotating from the earth centered frame to the// 
horizontal local frameSGQuatf qEc2Hl = SGQuatf::fromLonLatRad((float)lon, 
(float)lat);// The orientation wrt the horizontal local framefloat 
heading = ifce->get_Psi();float pitch = ifce->get_Theta();float roll = 
ifce->get_Phi();SGQuatf hlOr = SGQuatf::fromYawPitchRoll(heading, pitch, 
roll);// The orientation of the vehicle wrt the earth centered frame
motionInfo.orientation = qEc2Hl*hlOr;
// multiplayermgr.cxx 
--  SGVec3f 
angleAxis;  motionInfo.orientation.getAngleAxis(angleAxis);  for (unsigned i = 
0 ; i < 3; ++i)PosMsg.orientation[i] = XDR_encode_float (angleAxis(i));


However, using the above code snippets I am not able to get "good" orientation 
values; for instance consider the following values...
lon = 0lat = 0heading = 0pitch = 0roll = 0
from these values I get the following orientation values...
qEc2Hl:X: 0Y: -0,7071068Z: 0W: 0,7071068
hlOr:
X: 0Y: 0Z: 0W: 1

qEc2Hl*hlOr:X: 0Y: 0Z: 0W: 1

AngleAxis[]:X: 0Y: -0,99965771459Z: 0

Can you help me with this issue?Thank you in advance for your support and 
cooperation.Kind regards
Marco

Re: [Flightgear-devel] [flightgear-devel] Building TerraGear

[Behlül UÇAR]

Thanks for your answer.

But I already have plib 1.8.5 installed, I can build and run flightgear,
otherwise it would be impossible to build it without plib.

I already have simgear 1.9.1 installed.

Can it be a version mismatch? Maybe another version of plib is required for
building it?

Or maybe i have to give it a special path for plib libraries. Although it
can see plib/pu.h while checking for plib dependency in configure step, not
being able to find plib/sg.h of it is really weird. (I manually checked and
saw that there is a sg.h file in /usr/include/plib directory and it's not an
empty file.)

Can someone please enlighten me in that issue?

You will need to have plib installed.
