OpenSimulator is an open source 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. 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 released under a BSD License, a commercially friendly license to embed OpenSimulator in products.

Out of the box, OpenSimulator can be used to simulate a virtual environment similar to Second Life™, given that it supports the SL client protocol. OpenSimulator-based virtual worlds can be accessed with all SL viewers. However, OpenSimulator is neither a clone of Second Life nor does it aim at becoming such a clone. On the contrary, OpenSimulator lacks support for many of the game-specific features of Second Life while aggressively pursuing innovative directions towards becoming the bare bones server of the Metaverse. As such, other environments, protocols and features are supported via add on modules.

OpenSimulator is getting more stable as it approaches release 1.0, but we still consider it alpha software; so should you.

Features

• 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 ODE.
• Supports clients that create 3D content in real time.
• Supports inworld scripting using a number of different languages, including LSL/OSSL, C#, JScript and VB.NET
• Provides unlimited ability to customize virtual world applications through the use of scene plugin modules.

Using OpenSimulator

The fastest way to get started using OpenSimulator is to create an account on OSGrid, then download the Hippo Viewer or Linden Lab's Second Life viewer (amongst others) to connect to OSGrid. This process should take no longer than 10 minutes, and will give you a flavor for what OpenSimulator is like.

You can also easily connect to any one of the many public grids on the internet.

Or you could Download and run a simple standalone OpenSim on your Windows, Linux or Mac desktop to create and preview content.

Participating in the OpenSimulator Community

OpenSimulator is an open source project, and is powered by the community members that devote time and energy to the effort. There are many ways to participate and contribute to the community:

• Participate via IRC - #opensim (for users), #opensim-dev (for developers) and #opensim-scripts
• Participate via the mailing lists - opensim-users (for users) and opensim-dev (for developers).
• Contribute to this wiki, making the OpenSimulator documentation even better.
• Report bugs, submit patches or submit content contributions via our mantis bug tracker
• Create an OpenSimulator related project hosted on the Forge or elsewhere on the web. In the forge there are over a dozen registered projects, and it's a great way to further extend the OpenSimulator community.
• Participate to open content creation for OpenSimulator. More details at Artist Home.
• Blog about OpenSimulator, and let us know about that blog on #opensim so it can be added to Planet OpenSim
• Participate in one of the weekly Office Hours for OpenSimulator. We currently have weekly office hours for development, wiki work, and testing.
• Secure project infrastructure by donating to the OpenSim Project Infrastructure Fund.
