href="getstart.html#QQ2-14-81" name="x14-81000C.1">A Sketch on the History of <span
class="ptmbi7t---109">FlightGear</span></a></h3>
<!--l. 38--><p class="noindent">History may be a boring subject. However, from time to time there are people asking for
the history of <span
class="ptmbi7t---109">FlightGear</span>. As a result, we&#8217;ll give a short outline.
<!--l. 40--><p class="indent"> The <span
class="ptmbi7t---109">FlightGear </span>project goes back to a discussion among a group of net citizens in
1996 resulting in a proposal written by David Murr<a
name="dx14-81001"></a> who, unfortunately, dropped out of
the project (as well as the net) later. The original proposal<a
name="dx14-81002"></a> is still available from the
<span
class="ptmbi7t---109">FlightGear </span>web site and can be found under
<!--l. 44--><p class="indent"> <a
href="http://www.flightgear.org/proposal-3.0.1" >http://www.flightgear.org/proposal-3.0.1</a>.
<!--l. 47--><p class="noindent">Although the names of the people and several of the details have changed over time, the
spirit of that proposal has clearly been retained up to the present time.
<!--l. 51--><p class="indent"> Actual coding started in the summer of 1996 and by the end of that year
essential graphics routines were completed. At that time, programming was mainly
performed and coordinated by Eric Korpela<a
name="dx14-81003"></a> from Berkeley University. Early code ran
under Linux<a
name="dx14-81004"></a> as well as under DOS<a
name="dx14-81005"></a>, OS/2<a
name="dx14-81006"></a>, Windows 95/NT<a
name="dx14-81007"></a>, and Sun-OS<a
name="dx14-81008"></a>. This
was found to be quite an ambitious project as it involved, among other things,
writing all the graphics routines<a
name="dx14-81009"></a> in a system-independent way entirely from
scratch.
<!--l. 59--><p class="indent"> Development slowed and finally stopped in the beginning of 1997 when Eric was
completing his thesis. At this point, the project seemed to be dead and traffic on the
mailing list went down to nearly nothing.
<!--l. 63--><p class="indent"> It was Curt Olson<a
name="dx14-81010"></a> from the University of Minnesota who re-launched the
project in the middle of 1997. His idea was as simple as it was powerful: Why
invent the wheel a second time? There have been several free flight simulators<a
name="dx14-81011"></a>
available running on workstation<a
name="dx14-81012"></a>s under different flavors of UNIX<a
name="dx14-81013"></a>. One of these,
LaRCsim<a
name="dx14-81014"></a> (developed by Bruce Jackson<a
name="dx14-81015"></a> from NASA), seemed to be well suited
to the approach. Curt took this one apart and re-wrote several of the routines
such as to make them build as well as run on the intended target platforms. The
key idea in doing so was to exploit a system-independent graphics platform:
OpenGL<a
name="dx14-81016"></a>.
<!--l. 73--><p class="indent"> In addition, a clever decision on the selection of the basic scenery<a
name="dx14-81017"></a> data was made
in the very first version. <span
class="ptmbi7t---109">FlightGear </span>scenery is created based on satellite data
published by the U. S. Geological Survey<a
name="dx14-81018"></a>. These terrain data are available from
<!--l. 79--><p class="indent"> <a
href="http://edc.usgs.gov/geodata/" >http://edc.usgs.gov/geodata/</a>
<!--l. 82--><p class="noindent">for the U.S., and
<!--l. 86--><p class="indent"> <a
href="http://edcdaac.usgs.gov/gtopo30/gtopo30.html" >http://edcdaac.usgs.gov/gtopo30/gtopo30.html</a>,
<!--l. 89--><p class="noindent">resp., for other countries. Those freely accessible scenery data, in conjunction with
scenery building tools included with <span
class="ptmbi7t---109">FlightGear</span>, are an important feature enabling
anyone to create his or her own scenery.
<!--l. 95--><p class="indent"> This new <span
class="ptmbi7t---109">FlightGear </span>code - still largely being based on the original LaRCsim<a
name="dx14-81019"></a> code -
was released in July 1997. From that moment the project gained momentum again. Here
are some milestones in the more recent development history.
<h4 class="subsectionHead"><span class="titlemark">C.1.1</span> <a
href="getstartli1.html#QQ2-14-82" name="x14-82000C.1.1">Scenery</a></h4><a
name="dx14-82001"></a>
<ul class="itemize1">
<li class="itemize">Texture support<a
name="dx14-82002"></a> was added by Curt Olson<a
name="dx14-82003"></a> in spring 1998. This marked
a significant improvement in terms of reality. Some high-quality textures<a
name="dx14-82004"></a>
were submitted by Eric Mitchell<a
name="dx14-82005"></a> for the <span
class="ptmbi7t---109">FlightGear </span>project. Another set of
high-quality textures was added by Erik Hofman<a
name="dx14-82006"></a> in summer 2002.
</li>
<li class="itemize">After improving the scenery<a
name="dx14-82007"></a> and texture<a
name="dx14-82008"></a> support frame rate<a
name="dx14-82009"></a> dropped down to
a point where <span
class="ptmbi7t---109">FlightGear </span>became unflyable in spring 1998. This issue was
resolved by exploiting hardware OpenGL<a
name="dx14-82010"></a> support, which became available
at that time, and implementing view frustrum culling<a
name="dx14-82011"></a> (a rendering technique
that ignores the part of the scenery not visible in a scene), done by
Curt Olson<a
name="dx14-82012"></a>. With respect to frame rate<a
name="dx14-82013"></a> one should keep in mind that the
code, at present, is in no way optimized, which leaves room for further
improvements.
</li>
<li class="itemize">In September 1998 Curt Olson<a
name="dx14-82014"></a> succeeded in creating a complete terrain
model for the U.S. The scenery is available worldwide now, via a clickable
map <a
name="dx14-82015"></a>at:
<!--l. 111--><p class="noindent"><a
href="http://www.flightgear.org/Downloads/world-scenery.html" >http://www.flightgear.org/Downloads/world-scenery.html</a>.
</li>
<li class="itemize">Scenery<a
name="dx14-82016"></a> was further improved by adding geographic features<a
name="dx14-82017"></a> including
lakes, rivers,and coastlines later, an effort still going on. Textured runways
were added by Dave Cornish<a
name="dx14-82018"></a> in spring 2001. Light textures<a
name="dx14-82019"></a> add to the visual
impression at night. To cope with the constant growth of scenery data, a
binary scenery format was introduced in spring 2001. Runway lighting<a
name="dx14-82020"></a> was
introduced by Curt Olson<a
name="dx14-82021"></a> in spring 2001. Finally, a completely new set of
scenery<a
name="dx14-82022"></a> files for the whole world was created by William Riley<a
name="dx14-82023"></a> based on
preparatory documentation by David Megginson<a
name="dx14-82024"></a> in summer 2002. This is
based on a data set called VMap0<a
name="dx14-82025"></a> as an alternative to the GSHHS data<a
name="dx14-82026"></a> used
so far. This scenery is a big improvement as it has world wide coverage of
main streets, rivers, etc., while it&#8217;s downside are much less accurate coast
lines. <span
class="ptmbi7t---109">FlightGear</span>&#8217;s base scenery is based on these new scenery files since
summer 2002. The complete set is available via a clickable map,<a
name="dx14-82027"></a> too, from
<!--l. 117--><p class="noindent"><a
href="http://www.randdtechnologies.com/fgfs/newScenery/world-scenery.html" >http://www.randdtechnologies.com/fgfs/newScenery/world-scenery.html</a>.
</li>
<li class="itemize">There was support added for static objects<a
name="dx14-82028"></a> to the scenery in 2001, which
permits placing buildings, static planes, trees and so on in the scenery.
However, despite a few proofs of concept systematic inclusion of these
landmarks is still missing.
</li>
<li class="itemize">The world is populated with random ground objects<a
name="dx14-82029"></a> with appropriate type
and density for the local ground cover type since summer 2002. This
marks a mayor improvement of reality and is mainly thanks to work by D.
Megginson<a
name="dx14-82030"></a>.</li></ul>
<h4 class="subsectionHead"><span class="titlemark">C.1.2</span> <a
href="getstartli1.html#QQ2-14-83" name="x14-83000C.1.2">Aircraft</a></h4><a
name="dx14-83001"></a>
<ul class="itemize1">
<li class="itemize">A HUD<a
name="dx14-83002"></a> (head up display<a
name="dx14-83003"></a>) was added based on code provided by Michele
America<a
name="dx14-83004"></a> and Charlie Hotchkiss<a
name="dx14-83005"></a> in the fall of 1997 and was improved later by
Norman Vine. While not generally available for real Cessna 172<a
name="dx14-83006"></a>, the HUD
conveniently reports the actual flight performance of the simulation and may
be of further use in military jets later.
</li>
<li class="itemize">A rudimentary autopilot<a
name="dx14-83007"></a> implementing heading hold was contributed by Jeff
Goeke-Smith<a
name="dx14-83008"></a> in April 1998. It was improved by the addition of an altitude
hold and a terrain following switch in October 1998 and further developed
by Norman Vine<a
name="dx14-83009"></a> later.
</li>
<li class="itemize">Friedemann Reinhard <a
name="dx14-83010"></a>developed early instrument panel<a
name="dx14-83011"></a> code, which was
added in June 1998. Unfortunately, development of that panel slowed down
later. Finally, David Megginson <a
name="dx14-83012"></a>decided to rebuild the panel code from
scratch in January 2000. This led to a rapid addition of new instruments and
features to the panel, resulting in nearly all main instruments being included
until spring 2001. A handy minipanel was added in summer 2001.
</li>
<li class="itemize">Finally, LaRCsim<a
name="dx14-83013"></a>s Navion<a
name="dx14-83014"></a> was replaced as the default aircraft when the
Cessna 172<a
name="dx14-83015"></a> was stable enough in February 2000 - as move most users will
welcome. There are now several flight model<a
name="dx14-83016"></a> and airplane options to choose
from at runtime. Jon Berndt<a
name="dx14-83017"></a> has invested a lot of time in a more realistic and
versatile flight model with a more powerful aircraft configuration method.
<span
class="ptmbi7t---109">JSBSim</span>, as it has come to be called, did replace LaRCsim as the default
flight dynamics model<a
name="dx14-83018"></a> (FDM<a
name="dx14-83019"></a>), and it is planned to include such features
as fuel slosh effects, turbulence, complete flight control systems, and other
features not often found all together in a flight simulator. As an alternative,
Andy Ross<a
name="dx14-83020"></a> added another flight dynamics model called <span
class="ptmbi7t---109">YASim </span>(Yet Another
Flight Dynamics Simulator) which aims at simplicity of use and is based on
fluid dynamics, by the end of 2001. This one bought us flight models for a
747, an A4, and a DC-3. Alternatively, a group around Michael Selig<a
name="dx14-83021"></a> from
the UIUC<a
name="dx14-83022"></a> group provided another flight model along with several planes
since around 2000.
</li>
<li class="itemize">A fully operational radio stack<a
name="dx14-83023"></a> and working radios were added to the panel
by Curt Olson<a
name="dx14-83024"></a> in spring 2000. A huge database of Navaids contributed
by Robin Peel<a
name="dx14-83025"></a> allows IFR navigation since then. There was basic ATC<a
name="dx14-83026"></a>
support added in fall 2001 by David Luff<a
name="dx14-83027"></a>. This is not yet fully implemented,
but displaying ATIS messages<a
name="dx14-83028"></a> is already possible. A magneto switch<a
name="dx14-83029"></a> with
proper functions was added at the end of 2001 by John Check<a
name="dx14-83030"></a> and David
Megginson.<a
name="dx14-83031"></a>. Moreover, several panels were continually improved during
2001 and 2002 by John and others. <span
class="ptmbi7t---109">FlightGear </span>now allows flying ILS
approaches and features a Bendix transponder<a
name="dx14-83032"></a>.
</li>
<li class="itemize">In 2002 functional multi-engine support<a
name="dx14-83033"></a> found it&#8217;s way into <span
class="ptmbi7t---109">FlightGear</span>.
<span
class="ptmbi7t---109">JSBSim </span>is now the default FDM in <span
class="ptmbi7t---109">FlightGear</span>.
</li>
<li class="itemize">Support of &#8221;true&#8221; 3D panels<a
name="dx14-83034"></a> became stable via contributions from John
Check<a
name="dx14-83035"></a> and others in spring 2002. In addition, we got movable control
surfaces<a
name="dx14-83036"></a> like propellers etc., thanks to David Megginson.<a
name="dx14-83037"></a></li></ul>
<h4 class="subsectionHead"><span class="titlemark">C.1.3</span> <a
href="getstartli1.html#QQ2-14-84" name="x14-84000C.1.3">Environment</a></h4><a
name="dx14-84001"></a>
<ul class="itemize1">
<li class="itemize">The display of sun, moon and stars have been a weak point for PC flight
simulators for a long time. It is one of the great achievements of <span
class="ptmbi7t---109">FlightGear</span>
to include accurate modeling and display of sun, moon, and planets very
early. The corresponding astronomy code<a
name="dx14-84002"></a> was implemented in fall 1997 by
Durk Talsma<a
name="dx14-84003"></a>.
</li>
<li class="itemize">Christian Mayer, <a
name="dx14-84004"></a>together with Durk Talsma,<a
name="dx14-84005"></a> contributed weather code in the
winter of 1999. This included clouds<a
name="dx14-84006"></a>, winds<a
name="dx14-84007"></a>, and even thunderstorms<a
name="dx14-84008"></a>.</li></ul>
<h4 class="subsectionHead"><span class="titlemark">C.1.4</span> <a
href="getstartli1.html#QQ2-14-85" name="x14-85000C.1.4">User Interface</a></h4><a
name="dx14-85001"></a>
<ul class="itemize1">
<li class="itemize">The foundation for a menu system<a
name="dx14-85002"></a> was laid based on another library, the
Portable Library <span
class="ptmbi7t---109">PLIB</span><a
name="dx14-85003"></a>, in June 1998. After having been idle for a time, the
first working menu entries came to life in spring 1999.
<!--l. 161--><p class="noindent"><span
class="ptmbi7t---109">PLIB </span>underwent rapid development later. It has been distributed as a
separate package by Steve Baker<a
name="dx14-85004"></a> with a much broader range of applications
in mind, since spring 1999. It has provided the basic graphics rendering
engine for <span
class="ptmbi7t---109">FlightGear </span>since fall 1999.
</li>
<li class="itemize">In 1998 there was basic audio support<a
name="dx14-85005"></a>, i. e. an audio library and
some basic background engine sound. This was later integrated into the
above-mentioned portable library, <span
class="ptmbi7t---109">PLIB</span><a
name="dx14-85006"></a>. This same library was extended to
support joystick/yoke/rudder<a
name="dx14-85007"></a> in October 1999, again marking a huge step in
terms of realism. To adapt on different joystick, configuration options were
introduced in fall 2000. Joystick support was further improved by adding a
self detection<a
name="dx14-85008"></a> feature based on xml joystick files, by David Megginson<a
name="dx14-85009"></a> in
summer 2002.
</li>
<li class="itemize">Networking/multiplayer<a
name="dx14-85010"></a><a
name="dx14-85011"></a> code has been integrated by Oliver Delise <a
name="dx14-85012"></a>and Curt
Olson<a
name="dx14-85013"></a> starting fall 1999. This effort is aimed at enabling <span
class="ptmbi7t---109">FlightGear </span>to
run concurrently on several machines over a network<a
name="dx14-85014"></a>, either an Intranet or
the Internet<a
name="dx14-85015"></a>, coupling it to a flight planner<a
name="dx14-85016"></a> running on a second machine,
and more. There emerged several approaches for remotely controlling
<span
class="ptmbi7t---109">FlightGear </span>over a Network during 2001. Notably there was added support
for the &#8221;Atlas&#8221;<a
name="dx14-85017"></a> moving map program. Besides, an embedded HTTP server<a
name="dx14-85018"></a>
developed by Curt Olson<a
name="dx14-85019"></a> late in 2001 can now act a property manager<a
name="dx14-85020"></a> for
external programs.
</li>
<li class="itemize">Manually changing views<a
name="dx14-85021"></a> in a flight simulator is in a sense always &#8221;unreal&#8221;
but nonetheless required in certain situations. A possible solution was
supplied by Norman Vine<a
name="dx14-85022"></a> in the winter of 1999 by implementing code for
changing views using the mouse. Alternatively, you can use a hat switch for
this purpose, today.
</li>
<li class="itemize">A property manager<a
name="dx14-85023"></a> was implemented by David Megginson<a
name="dx14-85024"></a> in fall
2000. It allows parsing a file called <span
class="pcrr7t---109">.fgfsrc</span><a
name="dx14-85025"></a> under UNIX/Linux and
<span
class="pcrr7t---109">system.fgfsrc</span><a
name="dx14-85026"></a> under Windows for input options. This plain ASCII file
has proven useful in submitting the growing number of input options, and
notably the joystick settings<a
name="dx14-85027"></a>. This has shown to be a useful concept, and
joystick, keyboard, and panel settings are no longer hard coded but set using
*.xml files since spring 2001 thanks to work mainly by David Megginson
and John Check.<a
name="dx14-85028"></a></li></ul>
<!--l. 189--><p class="noindent">During development there were several code reorganization efforts. Various code
subsystems were moved into packages. As a result, code is organized as follows at
present:
<!--l. 193--><p class="indent"> The base of the graphics engine is <span
class="ptmb7t---109">OpenGL</span><a
name="dx14-85029"></a>, a platform independent graphics library.
Based on OpenGL<a
name="dx14-85030"></a>, the Portable Library <span
class="ptmbi7t---109">PLIB</span><a
name="dx14-85031"></a> provides basic rendering, audio, joystick
etc. routines. Based on <span
class="ptmbi7t---109">PLIB</span><a
name="dx14-85032"></a> is <span
class="ptmbi7t---109">SimGear</span><a
name="dx14-85033"></a>, which includes all of the basic routines
required for the flight simulator as well as for building scenery. On top of <span

name="dx14-85034"></a> there
are (i) <span

building tools.

<br class="newline">Helped tremendously in figuring out the Cygnus<a

.dll&#8217;s. Without him the first run-able Win32 version of <span
class="ptmbi7t---109">FlightGear </span>would have been
impossible.
<h3 class="sectionHead"><span class="titlemark">C.3</span> <a
href="getstart.html#QQ2-14-87" name="x14-87000C.3">What remains to be done</a></h3>
<!--l. 803--><p class="noindent">If you read (and, maybe, followed) this guide up to this point you may probably agree:
<span
class="ptmbi7t---109">FlightGear</span>, even in its present state, is not at all for the birds. It is already a flight
simulator which sports even several selectable flight models, several planes with
panels and even a HUD, terrain scenery, texturing, all the basic controls and
weather.
<!--l. 806--><p class="indent"> Despite, <span
class="ptmbi7t---109">FlightGear </span>needs - and gets - further development. Except internal tweaks,
there are several fields where <span
class="ptmbi7t---109">FlightGear </span>needs basics improvement and development. A
first direction is adding airport<a
name="dx14-87001"></a>s, buildings, and more of those things bringing scenery to
real life and belonging to realistic airports and cities. Another task is further
implementation of the menu system<a
name="dx14-87002"></a>, which should not be too hard with the basics being
working now. A lot of options at present set via command line or even during compile
time should finally make it into menu entries. Finally, <span
class="ptmbi7t---109">FlightGear </span>lacks any ATC<a
name="dx14-87003"></a> until
now.
<!--l. 815--><p class="indent"> There are already people working in all of these directions. If you&#8217;re a programmer
and think you can contribute, you are invited to do so.
<h4 class="likesubsectionHead"><a
href="#x14-88000C.3" name="x14-88000C.3">Achnowledgements</a></h4> Obviously this document could not have been written without all
those contributors mentioned above making <span
class="ptmbi7t---109">FlightGear </span>a reality.
<!--l. 824--><p class="noindent">First, I was very glad to see Martin Spott <a
name="dx14-88001"></a>entering the documentation effort. Martin
provided not only several updates and contributions (notably in the OpenGL section) on
the Linux side of the project but also several general ideas on the documentation in
general
<!--l. 826--><p class="indent"> Besides, I would like to say special thanks to Curt Olson,<a
name="dx14-88002"></a> whose numerous scattered
Readmes, Thanks, Webpages, and personal eMails were of special help to me and were
freely exploited in the making of this booklet.
<!--l. 830--><p class="indent"> Next, Bernhard Buckel <a
name="dx14-88003"></a>wrote several sections of early versions of that Guide and
contributed at lot of ideas to it.
<!--l. 833--><p class="indent"> Jon S. Berndt <a
name="dx14-88004"></a>supported me by critical proofreading of several versions of the
document, pointing out inconsistences and suggesting improvements.
<!--l. 836--><p class="indent"> Moreover, I gained a lot of help and support from Norman Vine<a
name="dx14-88005"></a>. Maybe, without
Norman&#8217;s answers I would have never been able to tame different versions of the <span
class="ptmbi7t---109">Cygwin</span>
- <span
class="ptmbi7t---109">FlightGear </span>couple.
<!--l. 840--><p class="indent"> We were glad, our Mac expert Darrell Walisser <a
name="dx14-88006"></a>contributed the section on
compiling under Mac OS X. In addition he submitted several Mac related hints and
fixes.
