realXtend is a project for creating an open-source virtual world platform which is intended to extend the capabilities of OpenSimulator to include features which are not available in the original Second 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.
Viewer
Initially, in early 2008, realXtend published a custom viewer derived from Linden Labs's own SL viewer; a free, open-source client (or viewer) software application for Microsoft Windows which allows for viewing and accessing both Second Life and multiple OpenSimulator-based virtual world grids, the realXtend viewer is licensed under the GNU GPL.
The realXtend viewer uses the OGRE engine, and it provides real-time shadows, improved lighting simulation, meshes and realistic avatars. The official Second Life physics engine is the proprietary Havok engine. The viewer connects to the OpenSim codebase trunk via the separate ModRex[2] utility.
Future
Beginning in 2009, the project began to work on a newer, original viewer, codenamed Naali, which is licensed under the BSD license and coded to implement a more robust viewing architecture. The new viewer and its SDK are now known as Tundra. It makes use of OpenSim's contributions policy, and, like Taiga, is relicensed under the Apache License v2.
