[Flightgear-devel] Free simulator of the Frecce Tricolori aerobatic jet

2005-07-28 Thread senerchi

At this site http://hcilab.uniud.it/pan  you can download the results of a joint
project between the HCI Lab of the University of Udine
and the aerobatic team of the Italian Air Force (the
Frecce Tricolori).

The Lab has produced a detailed, flyable model
of the MB-339 PAN jet. The leader of the Frecce Tricolori
(Capt. Tammaro) was a member of the development team
and beta-tester of the model. Development took about
1 year, at the end of which the Frecce Tricolori 
officially approved the public release of the model.

[Flightgear-devel] Free simulator of the Frecce Tricolori aerobatic jet

2005-07-28 Thread senerchi

I'm glad that you appreciate our work.

Don't miss the video about the making of the MB-339 PAN.
We have slightly modified FlightGear source code to enable 
an head tracking sensor for controlling the cockpit view.
The video shows the Capt. Tammaro during the beta-testing of 
our Low-Cost Immersive Flight Simulation with an Head Mounted Display,

If you like Frecce Tricolori we have also realeased a 3DWeb based project:
http://frecce3d.uniud.it/

Since the MB-339 PAN is an on-going project, we plan to release 
an improved version of the aircraft (with smokes?). If anyone
at flightgear.org would like to link our MB-339 PAN project in the Related 
Projects
section, we would be very happy.  

Bye, Augusto.

2005-07-28 Thread Dave Culp
 Since the MB-339 PAN is an on-going project, we plan to release
 an improved version of the aircraft (with smokes?).

We have smoke/contrails now, but they need a lot of work:

 http://home.comcast.net/~davidculp2/contrails.jpg

They look OK from some angles, and look bad from others.  I tried to add a 
smoke generator to the OV-10 model (The real OV-10 can inject oil into the 
right exhaust stack to make white smoke), but it doesn't look good enough to 
use.


The present system makes smoke/contrails by releasing AI objects rapidly.  
There are three problems with it now:

1)  Orienting the objects properly.  Only applies for long (i.e. cylindrical, 
rectangular) models.

2)  Matching the release rate to the airplane's speed.

3)  Making a smoke model that merges well with the others.  I've heard (on 
this list) that this may be a plib limitation.  It may require the use of a 
different visual model, like billboards or particle fields.


On the other hand, maybe a whole new tactic is needed.

I'm sure someone has already done some work on particle smoke. ISTR

Quite probably better to ask; my 'get stuck in' mentality is getting the

The license is obviously not GNU/GPL compliant but then it doesn't have to be 
because the a/c is not part of the FlightGear 'distribution'. (although it 
would be nice ;-) )

Hi Augusto,

This is wonderful work.  Of course I'm quite pleased with the quality of the 3D 
cockpit work. :-)

From a perhaps selfish perspective, I think that the FlightGear developers are 
feeling great pride that their work attracts such talent as displayed by the 
MB-339 PAN project.


There is one minor issue that should be brought up.  I might suggest taking a 
quick look at the GPL version 2 as distributed in the COPYING file with 
FlightGear:
http://cvs.flightgear.org/cgi-bin/viewcvs/viewcvs.cgi/data/COPYING?rev=1.3cvsroot=FlightGear-0.9content-type=text/vnd.viewcvs-markup

The pertinent part to note is: 

*** begin quote  ***

   2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1 
above, provided that you also meet all of these conditions:

  a) You must cause the modified files to carry prominent notices
  stating that you changed the files and the date of any change.

  b) You must cause any work that you distribute or publish, that in
  whole or in part contains or is derived from the Program or any
  part thereof, to be licensed as a whole at no charge to all third
  parties under the terms of this License.

*** end quote ***

As far as I can tell, the only place where a license change to GPL is needed is 
in the saitek.zip file,  but I haven't really looked that hard at all the items 
in the aircraft distribution file.  Those of you directly involved with the 
project would be better able to evaluate these requirements.  

Of course we respect any way in which the university and Frecce wish to protect 
their rights.  

My congratulations to all involved.  Great job!


Best,

Jim Wilson

Ah, it looks like others have raised a concern on the license.  As far as I can 
tell they are within rights, except with the modified saitek config.  But there 
could be a few files in the aircraft distribution.  I am not sure.  The 
greatest portion of this work is obviously original, but it is important for 
the details to be handled properly.  Keeping loose ends tied up is especially

Essentially, to do this right, the original model with textures and animations

Modifying a file is, pretty obviously, creating a derived work under
any reasonable interpretation. :)

 There is no argument possible about the JSBSim configuration files and
 (as far as I know) the 3d model.

In the case of the 3D model and textures, FlightGear has no relevant
copyright to protect.  Those are file formats that can be generated
and read by other tools.

The XML configuration files (the ones that were created from scratch,
not copied from existing ones), however, are clearly based on
FlightGear technology, and could theoretically be derived.  A sane
interpretation would treat these like documents though, and they
would be owned by their author.  I don't think any of us are making the
argument that all FlightGear configuration files are derived works.

Likewise, an Aeromatic-generated configuration file *can* be
considered a derived work, because it contains code that was written
originally by David Culp et. al.  There is some precedent for this
kind of thing (older versions of GNU bison generated parsers that were
derived works and must be GPLed), but most tools don't bother with
that notion and just treat the generated files as documents.  Bison
now contains a specific exception to the GPL for the generated parser
code, for example.

Basically, it seems to me like these guys are fine, with a few
nit-picky exceptions like the joystick configuration.  I don't think
we need to raise a stink, except to get their derived stuff released as a
separate tarball somewhere.

  Essentially, to do this right, the original model with textures and 
  animations would have to go into a separate zip file
 that is licensed as is and then the derived configuration files would go into 
 another zip file that is GPL'd.
 
 You can always argue what would be derived work: just the modified files 
 or the complete package. Personally I would say the first.
 

It does not matter, files or package.  Only part of the published material must 
be derived in order for that published material be required to be released 
under GPLv2.  The license is very clearly worded: You must cause any work that 
you distribute or publish, that in whole or in part contains or is derived from 
the Program or any part thereof, to be licensed as a whole at no charge to all 
third parties under the terms of this License.

The published archive (MB339-PAN.zip) is derived from any part thereof the 
FlightGear program.  Sure, you can split hairs over wheather you can publish 
two separately licensed works in the same archive file.  I am not trying to be 
nitpicky, just clear.  It certainly seems that the logical thing to do is 
distribute the non-GPL original artwork and configurations in a seperate zip 
file.  It would be the clearest and simplest way to avoid misunderstandings now 
and in the future.

About misunderstandings,  note that they can go both ways.  It would not be 
surprising for someone to mis-interpret the license files in the zip and 
erroneously modify and release under GPL some of the non-GPL parts of the 
339-PAN project.  You could have a few generations of derivation in circulation 
before someone realized that there was a problem.

Best,

Jim

 Hello all,
  
 Where do I find this aircraft. Is it released yet?

..chk down the $FGROOT/data/aircraft/ tree.

   Since the MB-339 PAN is an on-going project, we plan to release
   an improved version of the aircraft (with smokes?).
  
  We have smoke/contrails now, but they need a lot of work:

  They look OK from some angles, and look bad from others. I tried to
  add a smoke generator to the OV-10 model (The real OV-10 can inject
  oil into the right exhaust stack to make white smoke), but it
  doesn't look good enough to use.
 
 ..white smoke, for smoke signalling? ;o)

  Scenarios always come in sets of three: 
  best case, worst case, and just in case.
