it will be in a working state  :-)

Actually it's really remarkably straightforward now, mostly thanks to 
Melchior's tutorial.gui which lets one manipulate the marker circle within FG  
then dump all the relevant view and marker position XML with one click.

I did two Engine start procedure tutorials last night, one for the Hurricane 
and one for the Spitfire.  Took about ten minutes or so for the Hurricane 
one.

Given the up to date documentation in README.tutorials and the growing list 
of templates to borrow from, I hope we'll see more of these.  And I 
especially hope that people will start to use this system (in particular 
the target stuff) to produce interactive scenarios like search and rescue 
etc, these could provide some fun challenges...

Cheers,

AJ

 Yes, it starts fine here with CVS (plib branch).  Thanks for committing, this
 is a very nice addition for the new release.

Does so also in osg branch (cvs20070515) with OSG svn r6622; just a
bit confusing that the checkboxes for many switches (including
Battery) seem to be hidden.

Really an outstanding model; quite easy to fly, I even managed a
landing that only slightly resembled a kangaroo.

In order not to render too much of a Me too mail, I'd like to point
out, that the numbering of the flap gauge in the two pictures (2d, 3d)
 included in the an2.html is inconsistent. While it is listed as #20
and that number depicts the rightmost gauge in a group of 3 in the 2d
jpg, the same number is situated over the left gauge of the
corresponding group in the 3d picture. But the flapsetting gets
annunciated in the righthand gauge there too.

Looking at the real life photos, I cannot discern what setup should be
considered correct; it seems like only the righthand gauge is visible
(last picture, down left). As I cannot read Russian, or even decipher
Cyrillic, I don't know what the inscription means.

best regards

Yes, please - It's a must-have 0.9.11 feature IMO :-)

This one works fine for me on both OSG and PLIB (with the modified splash

Oh!? I'll have to dig deeper in my research.

If my {danube|shuttle}-splash.rgb files are actually 8-bit alpha, and they 
work for me, and I haven't heard any reports of problems, then that would 
discount my conclusion.

That would however, explain why my splash files are larger than desired.

no. it loads fine.

Yes, identify shows it as 8/8/8/1.
I can't tell if it is or isn't.
Gimp doesn't have an info panel that shows alpha bits, but using the color 
picker, I can't find any pixels with an alpha less than 255.

Ooops! That was a sloppy mistake.
I might actually promote my work in the _negative!_

Actually, I didn't have the an2 installed, so just copied the splash.rgb over 
to my model directory for testing.

I hear a complaint my models are too big.

I can't disagree with that.
Thanks to this thread, I have shrunk my image files by 1/3
   Yea!

Would it also help if I gut the interior and doors, and release a smaller,

I think I'm better off just making a new model from scratch that can be GPL'd.

Nope. But GIMP apparently generates corrupted files where compressed
scanlines aren't properly closed. (This is probably the reason why
they falsely claim that SGI doesn't support those. Yes, some spec
compliant readers may not like the corrupted GIMP files.  ;-)

I added a sanity check that makes sure we only read the number of
specified bytes, and no longer read until we find the mandatory
(which just may not be there in corrupt files). There should really
be more sanity checks. This code is rather sloppy. It makes invalid
assumptions about data type sizes, allocates insanely big buffers,
had no sanity checks, ...

Other corruption types will still crash this code, but the an2 file
should work now. Avoid GIMP and use KDE, and you'll be fine.  :-)

Umm ... but $FG_ROOT/Aircraft/bo105/splash.rgb *is* aggressively
compressed. Does it crash fgfs for anyone? I also tried other such
textures -- no crashes.

Can someone send me a link to a splash texture that crashes fgfs
for him/her? And a backtrace for the crash if possible.


BTW: KDE users can easily check if a texture was aggressively
compressed. I use this bash shell function:


  sgi() {
  for i in $*; do
  echo $i
  kfile --av $i 2/dev/null|
  egrep (Comment|Technical Details)|
  sed -e 's/Comment: *//' -e 's/Technical 
Details: *//';
  echo
  done
  }


Used on the bo105 texture:

  $ sgi $FG_ROOT/Aircraft/bo105/splash.rgb
  /usr/local/share/FlightGear/Aircraft/bo105/splash.rgb
  Name:Bo105 -- http://www.flightgear.org/ -- Melchior

  Bit Depth:   24 bpp
  Color Mode:  RGB
  Compression: Runlength Encoded, 50.5%
  Dimensions:  512 x 512 pixels
  Shared Rows: 0.3%


The Shared Rows percentage says that it's aggressively compressed.
It's a silly term, actually, as this is by no means aggressive. The
compression described in the SGI Image spec *is* aggressive, and
there is no other compression mentioned at all. Loaders which don't
grok it are just broken.

I tried loading it in Gimp, and saving in the same manner I have created the

It didn't work.
Still SegFaults with error 11.

So, since the Alpha channel is the biggest difference,
I tried Flattening the image, and it loads!

Conclusion: 1-bit alpha is supported. 8-bit alpha is not.

Hey, nice picture Yurik!

 Umm ... but $FG_ROOT/Aircraft/bo105/splash.rgb *is* aggressively
 compressed. Does it crash fgfs for anyone? 


First time I've seen this.


 Can someone send me a link to a splash texture that crashes fgfs
 for him/her? And a backtrace for the crash if possible.


For the an2-splash with 8-bit alpha color:

But then again: the separate (and broken) loader was probably only

that early stage. So fixing that is probably a waste of time.(?)

No, unfortunately this appears not to be an easy solution. The
splash-screen displays fine, but when it comes to display the 3D scene,
the whole sim crashes with a core dump.
I don't claim this to be your fault, I just notice that your model
appears to trigger a bug somewhere in FlightGear which crashes the sim
for me so I can't test it.

I write model for PLIB-devel  0.9.10 release, and have not OSG version for 
testing. Yestarday, I update my flightgear  simgear to OSG devel, and get 
sim crash like you.

and before crash, I get message about global material animation. Is it

Hi Yurik!

I have made some short test flights and didn't notice anything strange.
It is a nicely flying aircraft with a great looking cockpit!

One improvement I'd like is to map the propeller pitch adjustment to the 
n/N keys.

Cheers,

If you want disable automatic propeller pitch, you may comment first call of

But real an-2 has pitch automatic... IMHO, setting of couple command in user

I think you can (and are strongly encouraged to) override/redefine

That way the user does not have to add aircraft specific functions to his

As far as i know, 
JSBSIm in a generic way does not manage anything else than an automatic 
variable pitch propeller tuned according to a defined constant speed 
propeller.

So any manual tunning with N/n or anything else does not operate.

Anyhow if one, who develop a model within JSBSim and want a manual pitch 
propeller, there is a trick
 just comment out the lines which contains 
minpitch  /minpitch
  maxpitch  /maxpitch
into Propeller .xml file

And you will be able to tune manualy  the pitch

Interesting. What does the automatic pitch subsystem do? I wonder if it is
similar to a capability that is already in the JSBSim propeller model? I'd
be concerned that the two approaches could result in an instability.

Yes, I know this trick, and it work for some aircrafts. but for some value of 
rpm, there is oscillation in pitch/rpm feedback. I write custom procedure, 
for adjust feedback gain, and it work without problems.

And there is one issue: custom pitch control can help for 0.9.10 release 
users, for engine start. This problem has discussed here, it fixed for devel 
version, but for release, engine can not start without custom pitch control.

Ah, yes, now that you mention it:
The rbg loader for the splash screen is a different than the one for the 
models, simply because the splash-screen is showed before all the 
support libraries are initialized.

So it's indeed required not to use the aggressive RLE option for the 
splash screen images which isn't such a big deal since the image is 
removed from memory as soon as possible.

Hope this clarifies it a bit.

  sim version pls...
 
  windows? OSG or PLIB?

 Both OSG and PLIB last cvs  Linux

And if i take the splash.rgb file with Gimp load and save, i get a working an2 
loaded with that new splash file.

It seems I set not correct rgb options when save file. But I use gimp too 
and verify splash-screen under PLIB devel  0.9.10 release of FGFS... 
 
It's strange for my... splash-screen is very simple work... 
 
What's parameters of rgb you use?

I did used RLE compress.  (load and save)

The best could be for you to get the resulting splash.rgb file working for me

i have put it  there http://perso.orange.fr/GRTux/splash.rgb

  you will notice the size is a little bigger. 468,1 ko (new one) instead of 
467,6 (old one).

In the wiki flightgear-fileFormat page, I read directions that said to save in 
.sgi format with agressive RLE compression.  Then rename splash.sgi to 
splash.rgb
