<p>This generally means that the server is at it's capacity. You

<p>We could do that, since the initial download is about 25

megabytes. Especially for people who have to pay per-minute charges

for internet access, buying a CD is a convenient and possibly

cheaper option. Although we offer that service (see the website), we

encourage other groups to redistribute it for their users, especially

within an operating system distribution which makes installation even

faster and easier for new users.</p>

|

<p>Well, that depends. First make sure you are using the appropriate
|
||||
versions of FlightGear, SimGear, plib, zlib. If any of
|
||||
the packages are out of sync with the others, compilation may fail.</p>
|
||||
<p>The FlightGear <i>Downloads</i> page
|
||||
(<a href="http://flightgear.org/Downloads/">http://flightgear.org/Downloads/</a>)
|
||||
should tell you what versions you need if you are trying to compile
|
||||
the latest stable release. If you are using a development snapshot,
|
||||
make sure all three packages are up-to-date.</p>
|
||||
<p>Also ensure that you have some implementation of OpenGL with glut
|
||||
support with the appropriate header files. Linux users with nVidia
|
||||
cards should make sure you have the latest drivers from nVidia. Other
|
||||
Linux users make sure you have Mesa3D
|
||||
(<a href="http://mesa3d.org/">http://mesa3d.org/</a>)
|
||||
and your X server installed correctly. Windows users see
|
||||
<a href="http://www.x-plane.com/SYSREQ/v5ibm.html">http://www.x-plane.com/SYSREQ/v5ibm.html</a>,
|

</b>
|

<div class="indent">
|

<p>FlightGear (as of June 2001) uses the Portable Libraries (PLIB)
|
||||
for playing audio. The audio queue implementation of PLIB is far from
|
||||
optimal (in fact it's just wrong). This seems to work on other
|
||||
platforms quite well, but Irix expects things to be programmed
|
||||
properly.</p>
|
||||
<p>There has been discussion about using OpenAL
|
||||
(<a href="http://www.openal.org/">http://www.openal.org/</a>)
|
||||
for the next release of both PLIB and FlightGear. Tests show that
|
||||
the OpenAL audio implementation does the job right, meaning that
|
||||
these audio problems should be gone by then. In the mean time it is
|
||||
best to disable audio on Irix completely (by adding --disable-sound
|
||||
either on the command line or to your <code>$HOME/.fgfsrc</code>

<u>Why is my SGI machine so slow?</u>
|
||||
</a>
|

</b>
|
||||
<div class="indent">
|
||||
<p>First of all, one of the most common mistakes on SGI hardware is to
|
||||
forget to specify --fog-fastest. On most SGI machines the EXP2 shading
|
||||
model isn't hardware supported resulting in frame rates below 1 frame
|
||||
per second (fps).</p>
|
||||
<p>FlightGear makes extensive use of the OpenGL z-buffer feature,which
|
||||
on most older SGI hardware is only supported in software. This means
|
||||
that the CPU has to do all the z-buffer calculations in addition to the
|
||||
other tasks FlightGear involves (flight dynamics, scenery tracking,
|
||||
pushing commands into the graphics queue, etc). The following features
|
||||
are software rendered on low-end SGI machines (like Indy and
|
||||
Indigo):</p>
|
||||
<ul>
|
||||
<li>stencil and accumulation buffer</li>
|
||||
<li>depth queuing and depth buffering</li>
|
||||
<li>fogging, lighting, clipping and transforms</li>
|
||||
<li>texturing</li>
|
||||
</ul>
|
||||
<p>This means that running FlightGear with the following options may not
|
||||
even get the desired result:</p>
|
||||
<p>
|
||||
<code>./runfgfs --fog-disable --shading-flat --disable-skyblend \</code>
|
||||
<br>
|
||||
<code>--disable-textures --disable-clouds --disable-sound \</code>
|
||||
<br>
|
||||
<code>--disable-panel --enable-hud --disable-anti-alias-hud</code>
|
||||
</p>
|
||||
<p>I could even imagine that adding --enable-wireframe doesn't work on
|
||||
these machines (I would be happy to be proven wrong though).</p>
|
||||
<p>On a machine like O2 the following options give an acceptable
|
||||
result:</p>
|
||||
<code>./runfgfs --fog-fastest --disable-sound</code>
|
||||
<p>Since I don't have access to other SGI hardware I can't tell which
|
||||
options would be appropriate for your situation.</p>

<p>In his infinite wisdom the FlightGear Grand Master decided that

planes were to valuable to allow them to be destroyed by novice pilots

who seemed to crash a lot. The fact that nobody has bothered to model

crashes may have something to do with it too. :-)</p>

<p>The result of this as you have noticed is that with a little

practice an ingenuity you can trim the ship to fly inverted along the

ground.</p>
|

<p>The quick answer is to hit Ctrl+U (with the default key bindings)
|
||||
to warp the plane up 1000ft.</p>
|
||||
<p>For the stubborn people out there: The trick to learn is to roll
|
||||
back to normal (non inverted) do this by nursing the elevator to get
|
||||
to about 500 feet or so and use the ailerons to snap roll 180*.
|

This is all good avionics except for the plane not destroying

itself. Remember the controls work in reverse when you are inverted

<u>How do I place objects, like buildings, into FlightGear?</u>
|

</a>

</b>
|
||||
<div class="indent">
|
||||
<p>First, ensure that you have v0.7.7 or later, the scenery files
|
||||
where you plan to place the object, the actual model, and the
|
||||
longitude and latitude where you plan to place the object.</p>
|
||||
<p>Now get the altitude for your point. If you don't want to
|
||||
calculate this yourself, start FlightGear at your location and take
|
||||
note of the altitude. Here's an example command:</p>
|
||||
<p>
|
||||
<code>fgfs --lat=45.50 --lon=-75.73 2>&1 | tee fgfs.log</code>
|
||||
</p>
|
||||
<p>The altitude is probably in feet, so divide the starting altitude
|
||||
by 3.28.</p>
|
||||
<p>Search the output log file for the first occurrence of the string
|
||||
"Loading tile" and take note of the filename. In the above example,
|
||||
the output line looks like:</p>
|
||||
<p>
|
||||
<code>Loading tile /usr/local/Scenery/w080n40/w076n45/1712601</code>
|
||||
</p>
|
||||
<p>Copy a 3D model in a format that Plib understands to the same
|
||||
directory as the tile file. Edit the text file in that directory
|
||||
consisting of the tile name with the extension ".stg". The file will
|
||||
already exist if there is an airport on the tile; otherwise, you can
|
||||
create it from scratch. In our example, the filename is:</p>
|
||||
<p>
|
||||
<code>/usr/local/Scenery/w080n40/w076n45/1712601.stg</code>
|
||||
</p>
|
||||
<p>At the end of the file, add a new entry for your object,
|
||||
consisting of the word "OBJECT_STATIC" followed by the model name,
|
||||
the longitude in degrees, the latitude in degrees, the altitude in
|
||||
meters, and the heading in degrees. In our example the line looks
|
||||
like:</p>
|
||||
<p>
|
||||
<code>OBJECT_STATIC Towerax.ac -75.73 45.40 60 0</code>
|
||||

<p>Contributing to the 2D panel doesn't require any coding at all,
|
||||
just a minimal knowledge of XML syntax (i.e. five minutes' worth)
|
||||
and good skills with drawing and/or paint programs. Every instrument
|
||||
on the current panel, with the partial exception of the magnetic
|
||||
compass, is defined entirely in XML with no custom C++ code. If

you want to get started, take a look at John Check's excellent intro
|
||||
(<a href="http://rockfish.net/fg/README.xmlpanel">http://rockfish.net/fg/README.xmlpanel</a>).

<p>Likewise, if you want to create a 3D cockpit for FlightGear, or to
|
||||
create buildings, external aircraft models, etc., your help is
|
||||
*desperately* needed. The only rule is to go easy on the triangles
|
||||
-- a model with 50,000 triangles probably won't be usable in
|
||||
FlightGear, and one with 5,000 triangles, only marginally. If you
|
||||
can design a nice 3D cockpit interior for a Cessna 172 (for example)
|
||||
in a 3D design program such as ac3D or ppe, we have coders who will
|
||||
be happy to add the support code in the C++.</p>
|
||||
<p>If, on the other hand, you really want to get your hands dirty
|
||||
with C++ coding, you'll have to buy a good OpenGL book eventually.
|
||||
However, FlightGear uses a high-level library, plib, that hides most
|
||||
of the details of OpenGL. To get started with 3D C++ coding, you
|
||||
can take a look at the plib documentation and learn only as much

OpenGL as you need, when you need it.</p>

<p>We have an initial stab at this that is incomplete and only seems
|
||||
to work under Linux. We'd love to find someone to pick up the
|
||||
slack here and develop this further. Specifically, plib now has
|
||||
some low level networking support for mult-player games. It would
|
||||
also be nice to develop support for the DIS protocol.</p>

<p>No, not at this time. Most of our developers are primarily
|
||||
interested and focused on civilian aviation. We aren't explicitly
|
||||
excluding these features -- we just haven't had anyone who seriously
|
||||
wanted to develop these areas.</p>
