== Textures ==

Textures are images used to cover surfaces of 3d models and terrain. Textures can be anything form 1x1 to 1024x1024 images. Most of the textures for buildings, items and clothes are usually 512x512.

== Models ==

Models are 3 dimensional objects which are formed from faces and textures. Models come in many flavors but currently OpenSimulator supports parametrized primitives and sculpted primitives. Parametrized primitives can be created in world with build functionality. Sculpted primitives are defined by a special bitmap image which can be created with 3d modeling programs which support sculptures.

Yet unsupported in core OpenSimulator are 3d models which can be created with 3d modeling softwares like Blender and be saved in various formats, also known as Mesh. RealXtend module to OpenSimulator already supports 3d models.

OpenSim Archives

=How do I use the OpenSim Archive Function?=

==Introduction==

The OpenSim Archive (OAR) function has existed since r5469 (post 0.5.8). Basically, it does a similar job to load-xml2/save-xml2 in that it saves prims so that they can be later reloaded. However, OpenSim archives (OAR) go a step further in that they can save all the necessary asset data so that you may fully restore the terrain, the textures of objects and their inventories when loaded onto a completely different system using a different asset database.

==Usage==

From the region console, one can type

save oar [<filename>]

to save an OpenSim archive. If no filename is given, then the name region.oar is used in the current directory

To load an archive, type

load oar [<filename>]

at the console. If no filename is given, then the server looks for a file called region.oar in the current directory.

Currently by default, loading an archive will delete all the objects in the scene and replace them with the archive contents. It's like being in the Matrix (when they swap environments), except much slower (all the scene objects are slowly deleted before the new environment is loaded :-)

When an archive is loaded, owners will be restored if the relevant uuids can be found in the OpenSim installation's user database. Otherwise, prim ownership will default to the master avatar for the region.

I recommend that you use filenames with the extension '''.oar'''. The filename extension of the download links on this page is '''.tar.gz''' which illustrates that the '''.oar''' format is actually a zipped tar file.

==Examples==

===OAR file from "Lusitania Tester" for all===
[http://www.worldsimterra.com/index.php?option=com_content&view=article&id=163&Itemid=100263 OAR-File.tar.gz]- Every week (on Sunday after 21:00 UTC) a OAR file from "Lusitania Tester" of WorldSimTerra-Grid is available for use of building and rezz of different avatars. All the avatars of all the grids are invited to place their free buildings and rezz to share with the OpenSim community. To get the OAR file, the member of the OpenSim community will make the registration on the site, after logging in, the downloads are available on the "Avatar Toolbox" tab (this tab is only available after you login to the site)

Please feel free to place links to other environments here, though unfortunately you'll have to host them on some other site.

==Use cases==

Possible current uses are

1. To migrate data from an SQLite region database to one based on MySQL

2. To distribute entire regions to other people.

==Current limitations==

* Parcel information is not currently saved. This will be addressed in the future.
* Performance is not very good, especially with large archives. This will be addressed in the future

==File Formats==

[[OAR Format|OAR File Formats]]

==FAQ==

1. What is this .tar.gz format you are using for the internal OAR format? Why not zip?

.tar.gz is a standard unix way of zipping up files into a single larger compressed file for distribution. Windows users should be able to open these files using freeware programs such as [http://www.7-zip.org/ 7-zip].

I'm using .tar.gz because all the zip (and tar) libraries for .net are licensed either under the GPL (with exception) or under the MSPL. Unfortunately, not all members of the OpenSim development team are comfortable with the MSPL, so these libaries are not currently an option. It is also significantly easier to write code to create and read tar archives than zip archives.

Also, if you're only ever loading and saving oars (rather than pulling them apart and putting them back together), then you don't need to worry about the internal format at all :)

2. Can you load and save multiple regions to an archive?

Not yet.

3. Can you load and save parts of a region to an archive?

Not yet.

==Bugs==

* Due to a possible bug in the Mono 1.2.4 libraries, this feature may cause a debug dump when used (the problem appears to be in writing out a compressed stream). Mono 1.2.6 is okay. Since Mono 1.2.4 is fairly old now, this bug will not be addressed.

==Current Status==

Operational. Bug reports are appreciated [[User:Justincc|Justincc]] 14:53, 14 September 2009 (UTC)

Though we will strive to maintain compatibilty for old archives with newer OpenSimulator versions, please don't rely on these archives as the only backup for regions.

In addition to the OpenSim code itself, certain other packages need to be installed on different platforms in order to get OpenSim binaries to run.

As well as the information on this page (which should be expanded), you may find more information on dependencies in [[Build Instructions]] though this will also contain dependencies required only for building. This are also more hints in [[Troubleshooting]]

==Windows==

When using OpenSim on Windows XP, you need to have sp2 installed along with the newest version of the .net framework
Google knows where to find it [http://www.google.com/search?hl=en&ei=DTm6SrbECJ6H8Qab5MSMCg&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=.net+framework&spell=1 Here]

When using OpenSim on Windows Vista, You need to have the newest version of the .net framework, and run the program as administrator. (right click run as a administrator)

Some other errors occur if some other program is using port 80.

I don't believe any other extra packages need to be installed to get the binaries running. More information on this would be most welcome

==Linux==

The easiest plaform to get running on the Linux side is Ubuntu 8.10, 32bit. This is what most of the developers running Linux use. If you are looking for the quick path, start there.

Note: For people who have mono 2.0.1 or later installed, it may not be necessary to install the libmono-oracle2.0-cil package detailed below separately.

=== Ubuntu 8.04 (Hardy) / 8.10 (Intrepid) / 9.04 (Jaunty) ===
