IG Airlines:

This is inspired by a {{forum link|t=3295|text=thread found on the FlightGear forums at the end of March/2009 ("Going to Mount Everest")}}.

This page is meant to eventually help maintain a list of airports/places with challenging real life scenery and/or complex departure/approach procedures, so that this information can be used to showcase FlightGear aircraft performing interesting departures/approaches in challenging (e.g. mountaineous and windy) surroundings.

Various airports have been added here already, based on a [http://www.pprune.org/tech-log/331425-most-difficult-approaches.html related discussion by professional pilots on pprune.org].

==Airports to add==
* Tribhuvan International Aiport (ICAO:VNKT)
* Quito Airport (ICAO:SEQU)
* Peshawar International Airport (ICAO:OPPS)
* Leeds Bradford International Airport (ICAO:EGNM)
* Samos International Airport (ICAO:LGSM)
* Gilgit Airport (ICAO:OPGT)

'''Princess Juliana International Airport''' (IATA: '''SXM''', ICAO: '''TNCM''') serves the [[Dutch]] part of the island of Saint Martin. It is the second busiest airport in the Eastern Caribbean, after Luis Muñoz Marín International Airport in San Juan, Puerto Rico. It is named after Juliana of the Netherlands, who was crown princess when the airport opened.

== Runway ==
The airport is famous for its short runway — at only 2,180 metres (7,200 ft), it is barely long enough for heavy jets to land. Therefore, incoming airplanes approaching the island on short final for Runway 10 have to fly extremely low, passing only 10-20 meters (30-60 ft.) over relaxing tourists on Maho Beach.

== Scenery ==
Princess Juliana Airport is available from the [[FlightGear Scenery Database|scenemodels database]], located on tile w070n10.

When TerraSync is used, there is a major bug with TNCM, with water flooding part of the runway and the surrounding area, along with the airport being partly below sea level, causing certain views to appear as if the plane were under water. On the other hand though, it would make for a great mpevent-- rescuing stranded people!

== FlightGear Community ==

[[Pilots of the Caribbean]] used this airport. <br />
Princess Juliana Intl was the base for [[Island Virtual Airways]].

[[Atlas Virtual Airlines]] intends to fly flights to Princess Juliana.

'''Courchevel Airport''' is a small airport, infamous in the world of aviation, considered the home of one of the shortest runways in the world, which has a length of 525 meters and an inclination of 18.5% to slow the aircraft during landing. The airport has a dangerous approach, through a large valley, which may only be done by certified pilots. The airport is located on the side of a very steep hill that has seem some incidents.

It is not well developed in FlightGear, except by a custom scenery package; however it still presents a challenge to anyone brave enough to dare to land.

== Custom Scenery ==
The french PAF team has developed a custom scenery for multiple "altiports" (small airfields located in the Alps), which also includes Courchevel. The development thread can be found on [https://equipe-flightgear.forumactif.com/t443-altiports their forum] with download available from [https://equipe-flightgear.forumactif.com/t835-hangar-de-la-p-a-f-paf-team-hangar here](scroll down to Scènes/Scenery). It simulates the extraordinary terrain by using a 3D object, instead of the normal terrain generated by [[TerraGear]].

FlightGear IRC channel

IG Airlines:

{{DEFAULTSORT:IRC channel}}
The '''FlightGear IRC Network''' is an online system that will allow you to talk to a lot of people around the world and is related to everything about [[FlightGear]]. It's mostly used by developers, but it is also a good place to ask for help if you are having a question.

== Connecting to the network ==
It consists of localised servers that are all linked up to form a seamless chat network so if you are based in England you would connect to a nearby server in England and you would see exactly the same people as someone connecting to a server in the USA.

To connect to the IRCnet network you first need a suitable client. You can also use [http://www.xchat.org/ XChat] (Linux and Windows), [http://sourceforge.net/projects/xchataqua/ X-Chat Aqua] (X Chat Mac), [http://www.pidgin.im/ Pidgin], [http://colloquy.info/ Colloquy] (for Mac/iOS), [http://www.mirc.com/ mIRC], [https://Konversation.kde.org Konversation] or any other client.

When you first login to the network you must pick yourself a unique nickname for the current chat session. Nicknames can be up to 31 characters in length and contain numbers and some punctuation characters. Some examples of nicknames you can use are:

* Fred
* BIG_fred
* ^Fred^
* Fred-
* ^Fred
* fred007

It doesn't matter about capital or lower case letters in the nickname since they are treated the same when people want to contact you and there are some weird and obscure rules about nicknames such as them not being able to begin with a "-" character. Most of these rules have no rhyme nor reason to them but we didn't write the software, we just have to try and tell people how to use it. Have an experiment and see what suits you best.

Once you found your personal unique nickname you may want to register it with [[#Network_Services|NickServ]] (see below).

== Official hosts ==
{| class="wikitable"
! Host !! Location
|-
| de.irc.flightgear.org
| Germany
|-
| irc.flightgear.org
| currently an alias for de.irc.flightgear.org
|}

The '''port''' to connect to is 6667 (or 6659 for SSL) for each server.

These servers are interconnected to form the FlightGear IRC network. Please choose the host closest to you geographically.

The FlightGear IRC network has several channels, some of which are listed below. To obtain a real list, use the IRC command "/list".

== Network Services ==
=== NickServ ===
NickServ allows you to "register" a nickname and prevent others from using it. The following commands allow for registration and maintenance of nicknames; to use them, type

/msg NickServ ''COMMAND''

For more information on a specific command, type

/msg NickServ HELP ''COMMAND''

Some of the common commands are:

{| class="wikitable"
! Command !! Purpose
|-
| REGISTER
| Registers a nickname.
|-
| GROUP
| Adds a nickname to your account.
|-
| IDENTIFY
| Identifies to services for a nickname.
|-
| GHOST
| Reclaims use of a nickname.
|}

This service is intended to provide a way for IRC users to ensure their identity is not compromised. It is ''not'' intended to facilitate "stealing" of nicknames or other malicious actions. Abuse of NickServ will result in, at minimum, loss of the abused nickname(s).

=== ChanServ ===
ChanServ allows you to register and control various aspects of channels. ChanServ can often prevent malicious users from "taking over" channels by limiting who is allowed channel operator privileges. Some available commands are listed below; to use them, type

/msg ChanServ ''COMMAND''

For more information on a specific command, type:

/msg ChanServ HELP ''COMMAND''

{| class="wikitable"
! Command !! Purpose
|-
| REGISTER
| Registers a channel.
|-
| RECOVER
| Regain control of your channel.
|-
| FLAGS
| Manipulates specific permissions on a channel.
|}

=== MemoServ ===
MemoServ is a utility allowing IRC users to send short messages to other IRC users, whether they are online at the time or not. Both the sender's nickname and the target nickname must be registered in order to send a memo.

MemoServ's commands include:

{| class="wikitable"
! Command !! Purpose
|-
| READ
| Reads a memo.
|-
| SEND
| Sends a memo to a user.
|-

|}

For help on any of the above commands, type:

/msg MemoServ HELP ''COMMAND''

To see a list of all available MemoServ commands, type:

/msg MemoServ HELP

=== HostServ ===
HostServ allows users to request a virtual hostname. Normally we only allow IPs to be shown on a users
connection (so no dns lookups are made upon a new connection). To hide your host to other users you are
free to select a vhost from a predefined list (or a uniquely requested one) via hostserv. In that case
your selected hostname will be shown to others instead of your real IP.

To see the list of all available commands, type:

/msg HostServ HELP

Some commands of interest are:

{| class="wikitable"
! IRC Command !! Purpose
|-
| OFFERLIST
| Lists all available vhosts.
|-
| TAKE
| Take an offered vhost for use.
|-
| REQUEST

=== HostServ ===
HostServ allows users to request a virtual hostname. Normally we only allow IPs to be shown on a users
connection (so no dns lookups are made upon a new connection). To hide your host to other users you are
free to select a vhost from a predefined list (or a uniquely requested one) via hostserv. In that case
your selected hostname will be shown to others instead of your real IP.

</noinclude><includeonly>As many people are aware, there is a "new" flight simulator product that is being widely and actively marketed at the moment - '''{{PAGENAME}}''' (also promoted as '''ProFlightSimulator''', '''FlightSimPro''', '''Earth Flight Sim''', '''FlightProSim''', '''Real Flight Simulator'''). This product is a direct copy of a really old and outdated version of the freely-available [[FlightGear]] flight simulator for which the FlightGear project does not provide support. {{PAGENAME}} goes to extreme measures to hide the fact that they are simply copying an old version of FlightGear and reselling it under a different name, unsupported by the FlightGear community and without any visible value added to the outdated version of FlightGear. In some cases they have tried to turn the tables and say that FlightGear is ripping them off and pirating their work. This has caused some confusion for many people. To help provide some clarity, and answer some common questions, we (the core FlightGear development team) felt it was appropriate to make a statement, and provide a [[FAQ]].

FlightGear is an open-source flight simulator that was started in 1996. It is released as so called 'open source' under the [[GNU General Public License]] v2, and as such, it is free to download, use, modify and distribute with few restrictions. It has been developed with the collaboration of a large number of individuals over more than 15 years. FlightGear can be downloaded at no cost from http://www.flightgear.org.

=== Review of {{PAGENAME}} ===
{{PAGENAME}} is a commercial product very heavily based on FlightGear. Investigation by a number of FlightGear developers has found no difference between this and the FlightGear v1.9.1 release (which is an '''outdated''' version of FlightGear, released almost half a decade ago) other than a change of name. {{PAGENAME}} is in no way endorsed or supported by the core FlightGear development team or the FlightGear user community in general.

Given the similarities between {{PAGENAME}} and the old version of FlightGear, we would recommend that prospective buyers download the latest FlightGear version for free and satisfy themselves that the old re-branded FlightGear version distributed under the name {{PAGENAME}} provides worthwhile value for money before purchasing it. Even if you are certain that you want to run FlightGear v1.9.1, you can still download this freely from the web, without having to spend any money.

It may also be worth noting, that [http://www.virtualpilot3d.com/screenshots.htm their sample screenshots] also show some pictures obviously taken from Microsoft Flight Simulator X, which becomes obvious when paying attention to the blue glass cockpit screen backgrounds.

=== What are the differences between the two? ===
As far as we have been able to make out, the only difference between FlightGear v1.9.1 and {{PAGENAME}} is a change in name throughout the software, and the fact that you have to pay for it, as well as aggressive marketing tactics, misrepresenting the offered download package as something that it clearly isn't.

=== Legal or illegal? ===
The [[GNU GPL]] license, under which FlightGear is released, allows reselling under certain terms. The main issue that FlightGear developers have is the misleading marketing tactics used by pro flight sim that target unsuspecting users who aren't yet familiar with FlightGear. This is primarily an ethical, not a legal issue.

=== Is it legal to sell a copy of FlightGear, whether re-branded or not? ===
Yes, provided the seller is in compliance with a number of conditions detailed in the GPL. In fact, those interested in receiving a DVD containing FlightGear may do so through the main FlightGear website, and directly contribute to the project.

=== Has {{PAGENAME}} paid any money to FlightGear for the rights to the program? ===
No. No such payment is required, as FlightGear is GPL software. No such payment has been offered, no such payment has been made. Any claims by {{PAGENAME}} that they support the FlightGear project are entirely wishful thinking on their part.

=== Why do the FlightGear developers allow this? ===
The freedom to modify and enhance FlightGear is a core part of the project, and of open-source in general. Restricting the modifications that are allowed and what people can do with the software goes against that ethos.

=== Is there any relationship between the makers of {{PAGENAME}} and the FlightGear Project? ===
No.

=== Has {{PAGENAME}} contributed to the FlightGear project at all? ===
No.

=== I have purchased {{PAGENAME}}. Can I get a refund? ===
That is something you will have to take up with the distributors of {{PAGENAME}}. They guarentee a 60 day money back trial period, though some that have purchased FlightProSim have had trouble getting a refund and claim that FlightProSim did not respond to their requests for a refund. If you are having difficulty getting {{PAGENAME}} to cooperate and refund your purchase, you may want to call your credit card company or eWallet processor (ClickBank, PayPal, Skrill) and cancel the transaction. It may also help to get in touch with the corresponding affiliate program (e.g. commission junction, clickbank, click2pay etc) and report the product as being what it is (linking back to this project statement to help clarify the situation).

=== This whole situation makes me upset! What can I do? ===
First of all, the main problem here is the marketing tactics used by {{PAGENAME}} which exhibit very dubious ethical values. The FlightGear development teams feels the best way to combat this problem is through positive FlightGear marketing and by honestly pointing out that {{PAGENAME}} is simply an outdated rebranding of an already free flight sim called FlightGear.

We want all of you to stay positive, to be honest and to be fair!

If you want to help combat misleading marketing, let's all get the word out about FlightGear. FlightGear doesn't have the kind of advertising budget that the {{PAGENAME}} guys do. We need you!!! Please post wherever you can on web sites, forums, blogs, facebook, etc. We don't mind if someone chooses to buy {{PAGENAME}}, in fact that's great, as long as they have complete information in advance and aren't being misled by a slimy sales pitch that sounds too good to be true.

So let's get the word out and try to make sure that {{PAGENAME}} has to market to an "educated" audience!

[[File:Birds02.jpg|thumb|mass generation of birds. They actually flap wings and appear to go forward, though if you look closely, the swarm goes nowhere.]]

Thorsten came up with a toy for mass generation of birds. They actually flap wings and appear to go forward, though if you look closely, the swarm goes nowhere.<ref>{{cite web

the main guidance principle for this effect has been that it has to be cheap because the vast majority of users will see it for a few seconds flying past.
It's entirely unsuitable for things like following a migratory swarm with an ultralight. You get to see something that looks like birds in the scene - that's basically it.<ref>{{cite web

Birds are largely unpredictable which makes true simulation impossible anyhow. You could follow a group migrating birds but they don't fly indefinitely so now you would have to account for breaks and proper landing areas. Which is infeasible.<ref>{{cite web

{{#ev:youtube|GYTL3QlPKvQ||center}}

to see birds, you technically need to:
* have FG 2016.2+ with a working random objects code
* have random objects on
* run ALS
* fly in a region where they are defined

(Just south-west of Barcelona airport at the river delta is a good place - but it's of course the whole landclass).
They're low - some 100-200 m above ground. They're difficult to spot against bright background, but in the morning hours usually appear bright against the dark ocean. And they're small - so you need to get close to resolve them as birds, from the distance they look like dancing sparks or so.<ref>{{cite web

Howto:Place 3D objects with the UFO

2021-02-04T19:14:40Z

IG Airlines:

The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. Placing objects in the scenery is a really easy way to contribute to the [[FlightGear]] project. It does not require any programming knowledge, and you can contribute something valuable in just a few minutes.

This article gives an overview of placing, editing and saving objects using the UFO. You can get a list of flying controls and editing commands by pressing the {{key press|?}} key while flying the UFO.

== Choosing your object ==
The first thing you need is a 3D model to place in the scenery. The [[FlightGear Scenery Database]] ([http://scenemodels.flightgear.org/ scenemodels.flightgear.org]) maintains a huge library of generic models, which will have been included in your FlightGear installation under the <tt>[[$FG_ROOT]]/Models/</tt> directory. You can skip to the next section when using a generic model.

=== Consider the file sizes ===
If you add many complex models or models with big textures to the scenery it ''will'' increase the memory usage and slow down FlightGear.
Here are two lists with shared models and shared model textures sorted by file size:
* [[Shared models sorted by file size]]
* [[Textures of shared models sorted by file size]]

=== Creating your own models ===
Alternatively, you can create your own models. You should save it in a subdirectory of your [[$FG_ROOT]] folder. Two options seem reasonable, although others are possible as well:
* Shared model, not unique to a single objects (for example a wind turbine): save it in a subdirectory of <tt>[[$FG_ROOT]]/Models/</tt>. That is the standard directory where the UFO will go when you press the space bar {{Key press|Space}}.
* Static model, unique object (like the Eiffel Tower): save it in the respective subdirectory of the Scenery folder, e.g. <tt>[[$FG_ROOT]]/Scenery/Objects/w130n30/w123n37</tt>. To browse objects anywhere on your computer, press {{key press|L}} when using the UFO.

When creating your own object, make sure it is the correct size. In [[Blender]], units are meters. Note that you should be careful about using Google Earth, due to restrictions in their license that might prevent submitting your work to the FlightGear database. See {{forum link|t=3356|text=here}} and {{forum link|t=3415|text=here}}.

== Selecting the UFO ==
[[File:Ufo.png|400px]]

Now start FlightGear with the UFO as your aircraft and enable the console, which is needed later on. When launching FlightGear from command line, use <code>--aircraft=ufo --console</code>. In [[FGRun]], the "Show console" option on the last page should be checked.

== Placing objects ==
Once FlightGear has been started, fly with the UFO to roughly the place you want the model to be positioned.

[[File:EDDL View.png|400px]]

Let's say we want to position the F-15-lowpoly.xml object on a runway. We stop the UFO just above this intersection and press the space key. A Select Model window will open up where the contents of the <tt>[[$FG_ROOT]]/Models/</tt> directory will be shown (or press {{key press|L}} and you can go to any desired directory). Select your preferred model from this list, then close the window. The selected model path/name will be displayed in green text at the bottom left of the FlightGear screen.

[[File:Model popup.png|400px]]

To place the object, simply left-click on the position that you want to place it. By default, it is placed completely horizontal and rotated to point north. It will probably not have the correct orientation and it might be partly covered by the surrounding terrain, but we can adjust that.

[[File:F-15 runway.jpg]]

=== Rotating objects ===
Fly closer to the ground with the UFO, so that you can see it better.

Now press {{key press|{{=}}}} (earlier versions than 3.0 uses {{key press|Tab}}) and use the resulting sliders to adjust the latitude/longitude/elevation/heading of the model. NB: "Pitch" and "roll" will not be saved, so using them might be fun, but won't help eventually.

[[File:F-15 rotated1.png|400px]]

See the [[UFO from the 'White Project' of the UNESCO]] page for more information on the UFO command keys and exported file locations, or press {{key press|?}} while in FlightGear.

=== Deleting objects ===
There are three different ways to three different situations in which which you want to delete an object:
You want to delete the last object that you placed in this session:
: Press the [http://en.wikipedia.org/wiki/Backspace backspace button] ({{key press|← Backspace}}).
You want to delete an object that you placed in this session, but you have placed one or two models after it:
: That means that it is no longer active. Activate it by placing one more model '''on''' the object you want to delete, press the backspace button. Result: The model you want to delete starts blinking, which tells you that it is active.
You want to delete an object that is already saved in the corresponding .stg file and you don't know where it is:
: You don't know the filename: The model you want to delete is probably a shared model. You find it in the [http://scenemodels.flightgear.org/ scenery database]. Now you know the model's filename (e.g. [http://scenemodels.flightgear.org/modeledit.php?id=45 generic_skyscraper_01.ac] or [http://scenemodels.flightgear.org/modeledit.php?id=537 Office26x22.xml]).
: You still need to know where you find it. Place any model on that building and press {{key press|D}} to know in which file you find it (see [[#Exporting the result|Exporting the result]] below). If there are several objects of that type and you want to delete only one of them, find the one closest to the coordinates of your model placed on top.
: Open the .stg file, delete the whole model entry (see [[#Exporting the result|Exporting the result]] below). Done.

== Exporting the result ==
Now that the model is correctly positioned, press the {{key press|D}} key to dump the model position data to the terminal. A few lines will be printed on the console, providing the necessary orientation data.

[[File:Placing_objects_with_UFO_html_m4cf0cbf7.jpg]]

The most important lines are the last ones:
# e000n50/e008n50/3089154.stg
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude, and orientation. This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database.

You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear.

=== Saving the changes to your scenery ===
In the terminal window, you get three sections printed out by the UFO with very detailed information about what's going on. We need the lines at the end.

As noted above, the UFO helpfully exports the name of the scenery file where the object's coordinates have to be saved. In our example: e000n50/e008n50/3089154.stg

The default location for scenery objects is <tt>[[$FG_SCENERY]]/Objects/</tt>. Simply open the referenced .stg file, add the OBJECT_SHARED line to the bottom and save the file. Now you have your object's position saved, and it will appear inside the scenery every time you start FlightGear! There is one pitfall here. If TerraSync is enabled, which is the default in latest FlightGear versions, and you modified the stg file in the TerraSync folder, your modifications might be overridden by the syncing process. You might need to add the startup option --disable-terrasync for avoiding this and to keep your modifications.

In our example we would open in <tt>[[$FG_SCENERY]]/Objects/e000n50/e008n50/3089154.stg</tt> and add the following line:
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

For a short video demonstrating the .stg method, see the following video:
{{#ev:youtube|i2BSUOMyiIg|400|center}}

=== Saving to XML ===
Alternatively, if you press the {{key press|E}} key while developing scenery with UFO, FlightGear will generate an XML file with the dump of your current work in an "ufo-model-export.xml" file under [[$FG_HOME]].

=== Loading the XML file as part of FlightGear scenery ===
You can later reload this XML file with --config= command-line parameter:
Example for Linux: fgfs --config=$HOME/.fgfs/Export/ufo-model-export.xml

In Windows, this is done using the Advanced dialog, found on the last page of the [[FGRun]] GUI. Click Advanced and, under General, click the double-dot button, browse to the ufo-model-export.xml file and click OK.

== Sharing your updates with everyone! ==
Please, once you've improved the scenery around your place, consider sharing it with the community. This is done very easily using our [http://scenemodels.flightgear.org/submission scenery submission webforms]. More information and help on {{forum link|t=14671|text=the dedicated topic}} on the scenery forum.

The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude, and orientation. This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database.

You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear.

=== Saving the changes to your scenery ===
In the terminal window, you get three sections printed out by the UFO with very detailed information about what's going on. We need the lines at the end.

As noted above, the UFO helpfully exports the name of the scenery file where the object's coordinates have to be saved. In our example: e000n50/e008n50/3089154.stg

The default location for scenery objects is <tt>[[$FG_SCENERY]]/Objects/</tt>. Simply open the referenced .stg file, add the OBJECT_SHARED line to the bottom and save the file. Now you have your object's position saved, and it will appear inside the scenery every time you start FlightGear! There is one pitfall here. If TerraSync is enabled, which is the default in latest FlightGear versions, and you modified the stg file in the TerraSync folder, your modifications might be overridden by the syncing process. You might need to add the startup option --disable-terrasync for avoiding this and to keep your modifications.

In our example we would open in <tt>[[$FG_SCENERY]]/Objects/e000n50/e008n50/3089154.stg</tt> and add the following line:
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

For a short video demonstrating the .stg method, see the following video:
{{#ev:youtube|i2BSUOMyiIg|400|center}}

=== Saving to XML ===
Alternatively, if you press the {{key press|E}} key while developing scenery with UFO, FlightGear will generate an XML file with the dump of your current work in an "ufo-model-export.xml" file under [[$FG_HOME]].

=== Loading the XML file as part of FlightGear scenery ===
You can later reload this XML file with --config= command-line parameter:
Example for Linux: fgfs --config=$HOME/.fgfs/Export/ufo-model-export.xml

In Windows, this is done using the Advanced dialog, found on the last page of the [[FGRun]] GUI. Click Advanced and, under General, click the double-dot button, browse to the ufo-model-export.xml file and click OK.

== Sharing your updates with everyone! ==
Please, once you've improved the scenery around your place, consider sharing it with the community. This is done very easily using our [http://scenemodels.flightgear.org/submission scenery submission webforms].

Howto:Place 3D objects with the UFO

2021-02-04T19:03:54Z

IG Airlines:

The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. Placing objects in the scenery is a really easy way to contribute to the [[FlightGear]] project. It does not require any programming knowledge, and you can contribute something valuable in just a few minutes.

This article gives an overview of placing, editing and saving objects using the UFO. You can get a list of flying controls and editing commands by pressing the {{key press|?}} key while flying the UFO.

== Choosing your object ==
The first thing you need is a 3D model to place in the scenery. The [[FlightGear Scenery Database]] ([http://scenemodels.flightgear.org/ scenemodels.flightgear.org]) maintains a huge library of generic models, which will have been included in your FlightGear installation under the <tt>[[$FG_ROOT]]/Models/</tt> directory. You can skip to the next section when using a generic model.

=== Consider the file sizes ===
If you add many complex models or models with big textures to the scenery it ''will'' increase the memory usage and slow down FlightGear.
Here are two lists with shared models and shared model textures sorted by file size:
* [[Shared models sorted by file size]]
* [[Textures of shared models sorted by file size]]

=== Creating your own models ===
Alternatively, you can create your own models. You should save it in a subdirectory of your [[$FG_ROOT]] folder. Two options seem reasonable, although others are possible as well:
* Shared model, not unique to a single objects (for example a wind turbine): save it in a subdirectory of <tt>[[$FG_ROOT]]/Models/</tt>. That is the standard directory where the UFO will go when you press the space bar {{Key press|Space}}.
* Static model, unique object (like the Eiffel Tower): save it in the respective subdirectory of the Scenery folder, e.g. <tt>[[$FG_ROOT]]/Scenery/Objects/w130n30/w123n37</tt>. To browse objects anywhere on your computer, press {{key press|L}} when using the UFO.

When creating your own object, make sure it is the correct size. In [[Blender]], units are meters. Note that you should be careful about using Google Earth, due to restrictions in their license that might prevent submitting your work to the FlightGear database. See {{forum link|t=3356|text=here}} and {{forum link|t=3415|text=here}}.

== Selecting the UFO ==
[[File:Ufo.png|400px]]

Now start FlightGear with the UFO as your aircraft and enable the console, which is needed later on. When launching FlightGear from command line, use <code>--aircraft=ufo --console</code>. In [[FGRun]], the "Show console" option on the last page should be checked.

== Placing objects ==
Once FlightGear has been started, fly with the UFO to roughly the place you want the model to be positioned.

[[File:EDDL View.png|400px]]

Let's say we want to position the F-15-lowpoly.xml object on a runway. We stop the UFO just above this intersection and press the space key. A Select Model window will open up where the contents of the <tt>[[$FG_ROOT]]/Models/</tt> directory will be shown (or press {{key press|L}} and you can go to any desired directory). Select your preferred model from this list, then close the window. The selected model path/name will be displayed in green text at the bottom left of the FlightGear screen.

[[File:Model popup.png|400px]]

To place the object, simply left-click on the position that you want to place it. By default, it is placed completely horizontal and rotated to point north. It will probably not have the correct orientation and it might be partly covered by the surrounding terrain, but we can adjust that.

[[File:F-15 runway.jpg]]

=== Rotating objects ===
Fly closer to the ground with the UFO, so that you can see it better.

Now press {{key press|{{=}}}} (earlier versions than 3.0 uses {{key press|Tab}}) and use the resulting sliders to adjust the latitude/longitude/elevation/heading of the model. NB: "Pitch" and "roll" will not be saved, so using them might be fun, but won't help eventually.

[[File:F-15 rotated.png|400px]]

See the [[UFO from the 'White Project' of the UNESCO]] page for more information on the UFO command keys and exported file locations, or press {{key press|?}} while in FlightGear.

=== Deleting objects ===
There are three different ways to three different situations in which which you want to delete an object:
You want to delete the last object that you placed in this session:
: Press the [http://en.wikipedia.org/wiki/Backspace backspace button].
You want to delete an object that you placed in this session, but you have placed one or two models after it:
: That means that it is no longer active. Activate it by placing one more model '''on''' the object you want to delete, press the backspace button. Result: The model you want to delete starts blinking, which tells you that it is active.
You want to delete an object that is already saved in the corresponding .stg file and you don't know where it is:
: You don't know the filename: The model you want to delete is probably a shared model. You find it in the [http://scenemodels.flightgear.org/ scenery database]. Now you know the model's filename (e.g. [http://scenemodels.flightgear.org/modeledit.php?id=45 generic_skyscraper_01.ac] or [http://scenemodels.flightgear.org/modeledit.php?id=537 Office26x22.xml]).
: You still need to know where you find it. Place any model on that building and press {{key press|D}} to know in which file you find it (see [[#Exporting the result|Exporting the result]] below). If there are several objects of that type and you want to delete only one of them, find the one closest to the coordinates of your model placed on top.
: Open the .stg file, delete the whole model entry (see [[#Exporting the result|Exporting the result]] below). Done.

== Exporting the result ==
Now that the model is correctly positioned, press the {{key press|D}} key to dump the model position data to the terminal. A few lines will be printed on the console, providing the necessary orientation data.

[[File:Placing_objects_with_UFO_html_m4cf0cbf7.jpg]]

The most important lines are the last ones:
# e000n50/e008n50/3089154.stg
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude, and orientation. This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database.

This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database.

You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear.

=== Saving the changes to your scenery ===
In the terminal window, you get three sections printed out by the UFO with very detailed information about what's going on. We need the lines at the end.

As noted above, the UFO helpfully exports the name of the scenery file where the object's coordinates have to be saved. In our example: e000n50/e008n50/3089154.stg

The default location for scenery objects is <tt>[[$FG_SCENERY]]/Objects/</tt>. Simply open the referenced .stg file, add the OBJECT_SHARED line to the bottom and save the file. Now you have your object's position saved, and it will appear inside the scenery every time you start FlightGear! There is one pitfall here. If TerraSync is enabled, which is the default in latest FlightGear versions, and you modified the stg file in the TerraSync folder, your modifications might be overridden by the syncing process. You might need to add the startup option --disable-terrasync for avoiding this and to keep your modifications.

In our example we would open in <tt>[[$FG_SCENERY]]/Objects/e000n50/e008n50/3089154.stg</tt> and add the following line:
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

For a short video demonstrating the .stg method, see the following video:
{{#ev:youtube|i2BSUOMyiIg|400|center}}

=== Saving to XML ===
Alternatively, if you press the {{key press|E}} key while developing scenery with UFO, FlightGear will generate an XML file with the dump of your current work in an "ufo-model-export.xml" file under [[$FG_HOME]].

=== Loading the XML file as part of FlightGear scenery ===
You can later reload this XML file with --config= command-line parameter:
Example for Linux: fgfs --config=$HOME/.fgfs/Export/ufo-model-export.xml

In Windows, this is done using the Advanced dialog, found on the last page of the [[FGRun]] GUI. Click Advanced and, under General, click the double-dot button, browse to the ufo-model-export.xml file and click OK.

Howto:Place 3D objects with the UFO

2021-02-04T18:48:32Z

IG Airlines:

The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. Placing objects in the scenery is a really easy way to contribute to the [[FlightGear]] project. It does not require any programming knowledge, and you can contribute something valuable in just a few minutes.

This article gives an overview of placing, editing and saving objects using the UFO. You can get a list of flying controls and editing commands by pressing the {{key press|?}} key while flying the UFO.

== Choosing your object ==
The first thing you need is a 3D model to place in the scenery. The [[FlightGear Scenery Database]] ([http://scenemodels.flightgear.org/ scenemodels.flightgear.org]) maintains a huge library of generic models, which will have been included in your FlightGear installation under the <tt>[[$FG_ROOT]]/Models/</tt> directory. You can skip to the next section when using a generic model.

=== Consider the file sizes ===
If you add many complex models or models with big textures to the scenery it ''will'' increase the memory usage and slow down FlightGear.
Here are two lists with shared models and shared model textures sorted by file size:
* [[Shared models sorted by file size]]
* [[Textures of shared models sorted by file size]]

=== Creating your own models ===
Alternatively, you can create your own models. You should save it in a subdirectory of your [[$FG_ROOT]] folder. Two options seem reasonable, although others are possible as well:
* Shared model, not unique to a single objects (for example a wind turbine): save it in a subdirectory of <tt>[[$FG_ROOT]]/Models/</tt>. That is the standard directory where the UFO will go when you press the space bar {{Key press|Space}}.
* Static model, unique object (like the Eiffel Tower): save it in the respective subdirectory of the Scenery folder, e.g. <tt>[[$FG_ROOT]]/Scenery/Objects/w130n30/w123n37</tt>. To browse objects anywhere on your computer, press {{key press|L}} when using the UFO.

When creating your own object, make sure it is the correct size. In [[Blender]], units are meters. Note that you should be careful about using Google Earth, due to restrictions in their license that might prevent submitting your work to the FlightGear database. See {{forum link|t=3356|text=here}} and {{forum link|t=3415|text=here}}.

== Selecting the UFO ==
[[File:Ufo.png|400px]]

Now start FlightGear with the UFO as your aircraft and enable the console, which is needed later on. When launching FlightGear from command line, use <code>--aircraft=ufo --console</code>. In [[FGRun]], the "Show console" option on the last page should be checked.

== Placing objects ==
Once FlightGear has been started, fly with the UFO to roughly the place you want the model to be positioned.

[[File:EDDL View.png|400px]]

Let's say we want to position the catii-iii.xml object at the end of a taxiway. We stop the UFO just above this intersection and press the space key. A Select Model window will open up where the contents of the <tt>[[$FG_ROOT]]/Models/</tt> directory will be shown (or press {{key press|L}} and you can go to any desired directory). Select your preferred model from this list, then close the window. The selected model path/name will be displayed in green text at the bottom left of the FlightGear screen.

[[File:Model popup.png|400px]]

To place the object, simply left-click on the position that you want to place it. By default, it is placed completely horizontal and rotated to point north. It will probably not have the correct orientation and it might be partly covered by the surrounding terrain, but we can adjust that.

[[File:Placing_objects_with_UFO_html_12ee70a1.jpg]]

=== Rotating objects ===
Fly closer to the ground with the UFO, so that you can see it better.

Now press {{key press|{{=}}}} (earlier versions than 3.0 uses {{key press|Tab}}) and use the resulting sliders to adjust the latitude/longitude/elevation/heading of the model. NB: "Pitch" and "roll" will not be saved, so using them might be fun, but won't help eventually.

[[File:Placing_objects_with_UFO_html_439816e9.jpg|400px]]

See the [[UFO from the 'White Project' of the UNESCO]] page for more information on the UFO command keys and exported file locations, or press {{key press|?}} while in FlightGear.

=== Deleting objects ===
There are three different ways to three different situations in which which you want to delete an object:
You want to delete the last object that you placed in this session:
: Press the [http://en.wikipedia.org/wiki/Backspace backspace button].
You want to delete an object that you placed in this session, but you have placed one or two models after it:
: That means that it is no longer active. Activate it by placing one more model '''on''' the object you want to delete, press the backspace button. Result: The model you want to delete starts blinking, which tells you that it is active.
You want to delete an object that is already saved in the corresponding .stg file and you don't know where it is:
: You don't know the filename: The model you want to delete is probably a shared model. You find it in the [http://scenemodels.flightgear.org/ scenery database]. Now you know the model's filename (e.g. [http://scenemodels.flightgear.org/modeledit.php?id=45 generic_skyscraper_01.ac] or [http://scenemodels.flightgear.org/modeledit.php?id=537 Office26x22.xml]).
: You still need to know where you find it. Place any model on that building and press {{key press|D}} to know in which file you find it (see [[#Exporting the result|Exporting the result]] below). If there are several objects of that type and you want to delete only one of them, find the one closest to the coordinates of your model placed on top.
: Open the .stg file, delete the whole model entry (see [[#Exporting the result|Exporting the result]] below). Done.

== Exporting the result ==
Now that the model is correctly positioned, press the {{key press|D}} key to dump the model position data to the terminal. A few lines will be printed on the console, providing the necessary orientation data.

[[File:Placing_objects_with_UFO_html_m4cf0cbf7.jpg]]

The most important lines are the last ones:
# e000n50/e008n50/3089154.stg
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude, and orientation.

As noted above, the UFO helpfully exports the name of the scenery file where the object's coordinates have to be saved. In our example: e000n50/e008n50/3089154.stg

The default location for scenery objects is <tt>[[$FG_SCENERY]]/Objects/</tt>. Simply open the referenced .stg file, add the OBJECT_SHARED line to the bottom and save the file. Now you have your object's position saved, and it will appear inside the scenery every time you start FlightGear! There is one pitfall here. If TerraSync is enabled, which is the default in latest FlightGear versions, and you modified the stg file in the TerraSync folder, your modifications might be overridden by the syncing process. You might need to add the startup option --disable-terrasync for avoiding this and to keep your modifications.

In our example we would open in <tt>[[$FG_SCENERY]]/Objects/e000n50/e008n50/3089154.stg</tt> and add the following line:
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

For a short video demonstrating the .stg method, see the following video:

=== Saving to XML ===
Alternatively, if you press the {{key press|E}} key while developing scenery with UFO, FlightGear will generate an XML file with the dump of your current work in an "ufo-model-export.xml" file under [[$FG_HOME]].

=== Loading the XML file as part of FlightGear scenery ===
You can later reload this XML file with --config= command-line parameter:
Example for Linux: fgfs --config=$HOME/.fgfs/Export/ufo-model-export.xml

In Windows, this is done using the Advanced dialog, found on the last page of the [[FGRun]] GUI. Click Advanced and, under General, click the double-dot button, browse to the ufo-model-export.xml file and click OK.

Howto:Place 3D objects with the UFO

2021-02-04T18:41:39Z

IG Airlines:

The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. Placing objects in the scenery is a really easy way to contribute to the [[FlightGear]] project. It does not require any programming knowledge, and you can contribute something valuable in just a few minutes.

This article gives an overview of placing, editing and saving objects using the UFO. You can get a list of flying controls and editing commands by pressing the {{key press|?}} key while flying the UFO.

== Choosing your object ==
The first thing you need is a 3D model to place in the scenery. The [[FlightGear Scenery Database]] ([http://scenemodels.flightgear.org/ scenemodels.flightgear.org]) maintains a huge library of generic models, which will have been included in your FlightGear installation under the <tt>[[$FG_ROOT]]/Models/</tt> directory. You can skip to the next section when using a generic model.

=== Consider the file sizes ===
If you add many complex models or models with big textures to the scenery it ''will'' increase the memory usage and slow down FlightGear.
Here are two lists with shared models and shared model textures sorted by file size:
* [[Shared models sorted by file size]]
* [[Textures of shared models sorted by file size]]

=== Creating your own models ===
Alternatively, you can create your own models. You should save it in a subdirectory of your [[$FG_ROOT]] folder. Two options seem reasonable, although others are possible as well:
* Shared model, not unique to a single objects (for example a wind turbine): save it in a subdirectory of <tt>[[$FG_ROOT]]/Models/</tt>. That is the standard directory where the UFO will go when you press the space bar {{Key press|Space}}.
* Static model, unique object (like the Eiffel Tower): save it in the respective subdirectory of the Scenery folder, e.g. <tt>[[$FG_ROOT]]/Scenery/Objects/w130n30/w123n37</tt>. To browse objects anywhere on your computer, press {{key press|L}} when using the UFO.

When creating your own object, make sure it is the correct size. In [[Blender]], units are meters. Note that you should be careful about using Google Earth, due to restrictions in their license that might prevent submitting your work to the FlightGear database. See {{forum link|t=3356|text=here}} and {{forum link|t=3415|text=here}}.

== Selecting the UFO ==
[[File:Ufo.png|400px]]

Now start FlightGear with the UFO as your aircraft and enable the console, which is needed later on. When launching FlightGear from command line, use <code>--aircraft=ufo --console</code>. In [[FGRun]], the "Show console" option on the last page should be checked.

== Placing objects ==
Once FlightGear has been started, fly with the UFO to roughly the place you want the model to be positioned.

[[File:EDDL View.png|400px]]

Let's say we want to position the catii-iii.xml object at the end of a taxiway. We stop the UFO just above this intersection and press the space key. A Select Model window will open up where the contents of the <tt>[[$FG_ROOT]]/Models/</tt> directory will be shown (or press {{key press|L}} and you can go to any desired directory). Select your preferred model from this list, then close the window. The selected model path/name will be displayed in green text at the bottom left of the FlightGear screen.

[[File:Placing_objects_with_UFO_html_m184fb381.jpg|400px]]

To place the object, simply left-click on the position that you want to place it. By default, it is placed completely horizontal and rotated to point north. It will probably not have the correct orientation and it might be partly covered by the surrounding terrain, but we can adjust that.

[[File:Placing_objects_with_UFO_html_12ee70a1.jpg]]

=== Rotating objects ===
Fly closer to the ground with the UFO, so that you can see it better.

Now press {{key press|{{=}}}} (earlier versions than 3.0 uses {{key press|Tab}}) and use the resulting sliders to adjust the latitude/longitude/elevation/heading of the model. NB: "Pitch" and "roll" will not be saved, so using them might be fun, but won't help eventually.

[[File:Placing_objects_with_UFO_html_439816e9.jpg|400px]]

See the [[UFO from the 'White Project' of the UNESCO]] page for more information on the UFO command keys and exported file locations, or press {{key press|?}} while in FlightGear.

=== Deleting objects ===
There are three different ways to three different situations in which which you want to delete an object:
You want to delete the last object that you placed in this session:
: Press the [http://en.wikipedia.org/wiki/Backspace backspace button].
You want to delete an object that you placed in this session, but you have placed one or two models after it:
: That means that it is no longer active. Activate it by placing one more model '''on''' the object you want to delete, press the backspace button. Result: The model you want to delete starts blinking, which tells you that it is active.
You want to delete an object that is already saved in the corresponding .stg file and you don't know where it is:
: You don't know the filename: The model you want to delete is probably a shared model. You find it in the [http://scenemodels.flightgear.org/ scenery database]. Now you know the model's filename (e.g. [http://scenemodels.flightgear.org/modeledit.php?id=45 generic_skyscraper_01.ac] or [http://scenemodels.flightgear.org/modeledit.php?id=537 Office26x22.xml]).
: You still need to know where you find it. Place any model on that building and press {{key press|D}} to know in which file you find it (see [[#Exporting the result|Exporting the result]] below). If there are several objects of that type and you want to delete only one of them, find the one closest to the coordinates of your model placed on top.
: Open the .stg file, delete the whole model entry (see [[#Exporting the result|Exporting the result]] below). Done.

== Exporting the result ==
Now that the model is correctly positioned, press the {{key press|D}} key to dump the model position data to the terminal. A few lines will be printed on the console, providing the necessary orientation data.

[[File:Placing_objects_with_UFO_html_m4cf0cbf7.jpg]]

The most important lines are the last ones:
# e000n50/e008n50/3089154.stg
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude, and orientation. This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database.

You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear.

If TerraSync is enabled, which is the default in latest FlightGear versions, and you modified the stg file in the TerraSync folder, your modifications might be overridden by the syncing process. You might need to add the startup option --disable-terrasync for avoiding this and to keep your modifications.

In our example we would open in <tt>[[$FG_SCENERY]]/Objects/e000n50/e008n50/3089154.stg</tt> and add the following line:
OBJECT_SHARED Models/Tabu/catii-iii.xml 8.57928135 50.03667992 105.9972 111.1

=== Saving to XML ===
Alternatively, if you press the {{key press|E}} key while developing scenery with UFO, FlightGear will generate an XML file with the dump of your current work in an "ufo-model-export.xml" file under [[$FG_HOME]].

=== Loading the XML file as part of FlightGear scenery ===
You can later reload this XML file with --config= command-line parameter:
Example for Linux: fgfs --config=$HOME/.fgfs/Export/ufo-model-export.xml

In Windows, this is done using the Advanced dialog, found on the last page of the [[FGRun]] GUI. Click Advanced and, under General, click the double-dot button, browse to the ufo-model-export.xml file and click OK.
