=== What is OpenSimulator? ===
 +
{{FrontPageSidebar}}
  
OpenSim is a BSD Licensed Open Source project to develop a functioning virtual worlds server platform capable of supporting multiple clients and servers in a heterogeneous grid structure. OpenSim is written in [http://www.ecma-international.org/publications/standards/Ecma-334.htm C#], and can run under [http://www.mono-project.com/Main_Page Mono] or the [http://www.microsoft.com/net/ Microsoft .NET] runtimes.

OpenSimulator is an open source multi-platform, multi-user 3D application server. It can be used to create a virtual environment (or world) which can be accessed through a variety of clients, on multiple protocols. It also has an optional facility (the [[Hypergrid]]) to allow users to visit other OpenSimulator installations across the web from their 'home' OpenSimulator installation. In this way, it is the basis of a nascent distributed Metaverse.

OpenSimulator allows virtual world developers to customize their worlds using the technologies they feel work best - we've designed the framework to be easily extensible. OpenSimulator is written in [http://www.ecma-international.org/publications/standards/Ecma-334.htm C#], running both on Windows over the [http://www.microsoft.com/net/ .NET Framework] and on Unix-like machines over the [http://www.mono-project.com/ Mono] framework. The source code is released under a [[BSD License]], a commercially friendly license to embed OpenSimulator in products. If you want to know about our development history, see [[History]].
  
=== IRC move ===
+
Out of the box, OpenSimulator can be used to simulate virtual environments similar to [http://www.secondlifegrid.net Second Life™], given that it supports the core of [http://wiki.secondlife.com/wiki/Protocol SL's messaging protocol]. As such, these virtual worlds can be accessed with the regular [http://wiki.secondlife.com/wiki/Alternate_viewers SL viewers]. However, OpenSimulator does not aim to become a clone of the Second Life server platform. Rather, the project aims to enable innovative feature development for virtual environments and the Metaverse at large.
  
We are in the process of moving the IRC channel we use (#opensim) from EFNET to Freenode. If you can't find us on EFNET, get yourself over to Freenode! (There's also an #opensim-dev channel, also on Freenode, for those who are interested in digging into the guts of the code.)
+
OpenSimulator is getting more stable over time but is still a high complex software system that can suffer various bugs and quirks; handle with care!
  
=== OpenSim 0.4 Released! ===
+
=== Features ===
  
The OpenSim team is happy to announce the first alpha release of OpenSim, version 0.4.5.  This release focuses on stand-alone mode (with one or more regions). Some stuff works, a lot doesn't. If it breaks, you get to keep '''both''' pieces.
+
* Supports online, multi-user 3D environments as small as 1 simulator or as large as thousands of simulators.
 +
* Supports 3D virtual spaces of variable size within one single instance.
 +
* Supports multiple clients and protocols - access the same world at the same time via multiple protocols.
 +
* Supports realtime Physics Simulation, with multiple engine options including Bullet and ODE.
 +
* Supports clients that create 3D content in real time.
 +
* Supports inworld scripting using including LSL/OSSL and C#.
 +
* Provides unlimited ability to customize virtual world applications through the use of [[IRegionModule|scene plugin modules]].
  
Stuff that works:
+
For a more extensive list, see the [[Feature Matrix]].
* standalone mode with one or more regions
+
* basic physics (no object collisions)
+
* persistence of users, prims, assets, and inventory via [http://www.sqlite.org/ sqlite]
+
* basic building, custom-texture uploads
+
* avatar editing
+
* See [[OpenSim: Testing]]
+
  
More advanced physics, in-world scripting, grid mode, and support for other database backends are not supported in this release, though they may work from time-to-time before crashing with an earth-shattering kaboom!  All of these are under active development, and are being worked on for the 0.5.0 release.
