Brief History
• Started in 2007 in Sun Labs
• Challenge from VP of
Eco Responsibility
> “Let's build our next building in
the virtual world”
> MPK20 – Sun's Virtual Workplace
• Darkstar needed a demo
• Lots of interest in behind-the-firewall, app sharing
• Major reimplementation, Dec 2008 (v04 → v05)
• January 2010 – Oracle acquisition of Sun

In-world Access to Modules
• Three primary places
modules appear to
end users
• Modules can add
functionality to Insert
Object palette
• Allows users to create
multiple instances

15. 15Copyright 2010, Open Wonderland Foundation
Also Through Capabilities Dialog
• Capabilities are functionality that can
be applied to any in-world object
• Each can optionally include a property
sheet

Benefits of Modular Architecture
• Tailor functionality
> Program new features without changing core of system
> Integrate with real back-end systems, external data, or
real product user interfaces
• Refine customer experience
> Easily add and remove modules from configuration
> Simplify UI or add additional functionality
• Use the appropriate license
> Modules can be open source
> Or can be proprietary
• Enables ecosystem

Editor's Notes
Java
* Platform independence
* Java Web Start launching from a URL
Toolkit
* Strong focus on extensibility via Java programming
* More flexibility than scripting alone
* Makes integration with web services, enterprise systems, and data sources easier
Open source
* Both client and server are open source
* Both client and server can be extended
Wonderland was designed specifically with business and education collaboration in mind
Highly extensible - The Wonderland toolkit can be used to build almost any kind of interactive 3D virtual world. It is extensible using Java programming, rather than scripting alone.
The following slides show examples of virtual worlds that others have created using the Wonderland toolkit.
The most common activity people want to use a virtual world for is collaborating with live documents. The image here shows avatars interacting with an in-world whiteboard as well as a Firefox window.
The Wonderland vision is that organizations will run their own virtual world servers, just the way they currently run their own web servers. These servers can exist both inside and outside of firewalls. Rather than having one gigantic world where everyone goes, the Wonderland vision involves many, small, special purpose virtual worlds federated together. The newest version of the Wonderland client includes a URL field so that users can easily navigate from a virtual world on one server to a virtual world on a different server. Portals can be placed in the world as well, just as links are currently placed on web pages in the 2D world.
Java is also a great benefit when it comes to federation. The mobile code feature allows means that functionality needed when navigating to a different virtual world will automatically be downloaded when needed. For example, I move from a mixed-reality classroom to the Force on a Dipole world, the Java code needed to run the 3D physics simulation will be downloaded, but if the two worlds share other artwork, that shared artwork will be cached on my computer with no need to re-download.
Drag and drop
- Currently support jpg, png, svg (for whiteboard), kmz and dae (3D collada models)
- Soon to support PDF
Wonderland 0.5 is released under a GPL v2 with classpath exception license. This means that 3rd parties can create modules with any license they wish, open source or proprietary. Almost all extensions to Wonderland can be created as a module.
Around the same time as the 0.5 User Preview at the end of the summer, we will also be releasing a Wonderland Module Warehouse for people to find and share Wonderland extensions. A simple web-based UI allows Wonderland administrators to add or delete modules from a server installation.
