realXtend is a project for creating an open-source virtual world platform which is intended to extend the capabilities ofOpenSimulator to include features which are not available in the originalSecond Life project.
Like OpenSim, with which the project collaborates and from which it derives much of its code, realXtend is intended to allow individuals and groups to set up and browse their own virtual worlds without having to be connected to much larger worlds like Second Life.
It is created by the realXtend Association, which was founded in April 2011,[1] and is funded by both realXtend Foundation and Oulu Innovation ofOulu,Finland, as a cooperation by three Oulu based companies Evocativi, LudoCraft and Playsign.
Initially, in early 2008, realXtend published a custom viewer derived fromLinden Labs's own SL viewer; a free, open-source client (orviewer) software application for Microsoft Windows which allows for viewing and accessing bothSecond Life and multipleOpenSimulator-basedvirtual world grids, the realXtend viewer is licensed under the GNU GPL.
The realXtend viewer uses theOGRE engine, and it provides real-time shadows, improved lighting simulation, meshes and realistic avatars. The official Second Life physics engine is the proprietaryHavok engine. The viewer connects to the OpenSim codebase trunk via the separate ModRex[2] utility.
Beginning in 2009, the project began to work on a newer, original viewer, codenamedNaali, which is licensed under theBSD license and coded to implement a more robust viewing architecture. The new viewer and itsSDK are now known asTundra. It makes use of OpenSim's contributions policy, and, like Taiga, isrelicensed under theApache License v2.
Taiga, first released in 2009, is a server software suite derived from theScienceSim project (backed in part byIntel), which is itself derived from OpenSim's server project. Unlike OpenSim, Taiga packages and integrates the ModRex and ModCableBeach utilities (the latter of which provides access to the ROBUST inventory,[3] assets grid services, implements an webdav inventory/avatars and OpenID authentication).
