OpenSimulator is a 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 you to develop your environment using the technologies you feel work best - we've designed the software to be easily extendable through loadable modules to build completely custom configurations. OpenSimulator is released under a BSD License, making it both open source, and commercially friendly to embed in products.

Out of the box, OpenSimulator can be used to simulate a virtual environment similar to Second Life™ (including client compatibility). Other environments, protocols and features are supported via add on modules. For a list of available modules check out our forge site.

Although OpenSimulator is still considered alpha software, many people are doing exciting things with it.

Features

Even though OpenSimulator is relatively young software it already has many useful features

• Supports creating multiple 'worlds' in a single application instance.
• Supports multiple clients and protocols - access the same world at the same time via multiple protocols.
• Extensive ability to customize your avatar, both with custom clothing, skins, and attached objects.
• Realtime Physics Simulation, with multiple engine options including ODE.
• The ability to create content real time in the environment using in world building tools. What you see is what you get.
• In world application development using a number of different languages, including LSL/OSSL, C#, JScript and VB.NET

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 essay writing

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.
