= RealXtend =

RealXtend was an open source project which extended the feature set of OpenSimulator to support normal 3D meshes etc. which had not been available in Second Life(tm). The core development was funded and organized by Oulu Innovation in Finland, as a cooperation by three Oulu based companies Evocativi, LudoCraft and Playsign. The development process and decision making was open on mailing lists and IRC like normal Open Source projects, and any OpenSimulator or other developer was welcome to participate, and could get commit rights etc.

Information on how to connect the RealXtend viewer is defined by the [[ModRex]] interface. That page also gives more detailed information about the features.

Originally (in early 2008) RealXtend published an improved version of the GPL'd Second Life(tm) viewer. That viewer was built for Windows, however, running RealXtend in Wine was possible on Linux.

In 2009-2010 the focus has been on the development of a new viewer, Naali, which is compatible with the existing servers and content, but is written from scratch to facilitate development of new features. Naali is notable for being one of the few OpenSimulator viewers that was not a fork of a Second Life code. In particular it used a conventional 3D graphics engine, [https://www.ogre3d.org/ Ogre3D]. Naali is Apache licensed and applied the OpenSimulator contributions policy, so OpenSimulator server side developers could participate in viewer development. Naali was eventually renamed to Tundra and evolved in a different direction, leaving it no longer compatible with OpenSimulator. Instead it used a new server, forked from OpenSimulator, called Taiga. The entire project was abandoned in 2016.

[https://github.com/realXtend/tundra/tags Naali/Tundra source code] is still available on github. Versions 1.0.8 and earlier were usable with OpenSimulator. Version 0.4.0 and later required OpenSimulator to have the ModRex module installed.

== Overview ==
It's already possible to testrun modrex on linux/macos, so a crossplatform solution for the viewer is needed as well. Most libraries used in the RealXtend viewer are cross-platform. Nevertheless there are some windows dependencies, which prevents the viewer to compile and run on the Linux/OSX platform. In the meanwhile we can use the viewer through the use of wine. Wine allows to run native win32 applications on Linux, and on OSX using the Darwine modifications. Wine is not an emulator, and is faster than one might expect. RealXtend runs quite stable on wine(40/50 fps) with archlinux i686 distro, nvidia 8600GT, Athlon 3200+ and 2GB ram.

== Linux Procedure ==
* install git
* Get the latest wine
 git clone git://source.winehq.org/git/wine.git ~/wine-git
 cd ~/wine-git
* get the wglShareLists [http://www.winehq.org/pipermail/wine-patches/attachments/20081009/5631610c/attachment.patch patch] and copy into ~/wine-git/dlls/winex11.drv
* Do the patch for opengl.c
 patch -p0 &lt; attachment.patch
* Build wine(not as root)
 ~/wine-git/tools/wineinstall
* Add libraries(dx9, .net, etc.) using winetricks
* try to run the viewer
 wine ~/.wine/drive_c/Program\ files/RealXtend/realXtend.exe
* Tweak wine in case the viewer crashes. 
 winecfg
''There are some libraries which can be tweaked, in case the viewer crashes on load. My settings are: rpcrt4(buildin native), comctl32(native buildin)''

== Mac OSX Procedure ==
* Install [http://www.finkproject.org/ fink]. ''Notice that wine=&gt;realXtend won't work on PPC based MAC''
* Enable a [http://support.apple.com/kb/HT1528 root account] if you've not already done so
* Open a terminal, and login as root
* Update repository
 fink selfupdate-rsync

* Get the XCode developer tools from [http://developer.apple.com/ ADC] (requires free registration)
* Check out the Darwine code, and wine from the terminal, and unpack wine
 mkdir /Users/myuser/wine
 cd /Users/myuser/wine
 cvs -z3 -d:pserver:anonymous:@darwine.cvs.sourceforge.net:/cvsroot/darwine co -P distrib
 wget http://ovh.dl.sourceforge.net/sourceforge/wine/wine-1.1.21.tar.bz2
 tar -xjvf wine-1.1.21.tar.bz2
* Launch the darwine script
 cd distrib
 export VERSION=1.1.21
 ./create_darwine_distrib.sh $VERSION /Users/myuser/wine/wine-1.1.21
 find /sw/fink/dists -name wine.info
 http://fink.sodan.ecc.u-tokyo.ac.jp/item/14

== Known Quirks ==
* If the viewer refuses to start(complaining about window creation) after some succesful sessions, then remove ~/.wine/drive_c/windows/profiles/user/Application\ Data/realXtend
* After a normal quit, the colors of the desktop may become hippy-like distorted. Kill the proces instead to avoid it.(killall -15 realxtend.exe)
* The Skype part doesn't work with skype for linux. Didn't manage to test skype with wine(that may work)
* VNC on a prim doesn't work properly...
