blaxxun Community Platform 4 The blaxxun Community Platform is a modular client-server system that contains the technology to create virtual worlds.

Platforms:
• Linux
• SGI
• Sun
• Windows NT

Allows multiple remote users to interactively construct a shared 3D model.

Platforms:

• Windows NT

The DeepMatrix System is a multi-user VRML application. It enables several users to share a single VRML world and interact with it as it is possible with an ordinary VRML world. Users can jump between different worlds and these jumps can be triggered in any way. VRML events are distributed between the several instances of the VRML world on the different users computers. The system is split into a server program running on the web server where the VRML worlds and supporting HTML files are stored. The client is realised as a Java applet which uses the EAI to communicate with a VRML browser plugin such as Cosmoplayer or Worldview.

• Java

Gel is a new open framework for enabling multi-user three-dimensional worlds. Combining fresh ideas with established techniques, Gel incorporates curved, non-polygonal modeling and animation capabilities, peer-to-peer networking, global time stamps, visual authoring, and a distributed processing model for dynamism and deep interactivity. Unifying and enabling these features is a powerful new programming paradigm, a graph-based programming language.

Use Instant Community TM to create your own internet community. Instantly, with just a few mouse clicks. Its template-based structure allows for easy creation, quick deployment and hassle-free maintenance while integrating all the features needed to operate a successful online community.

The purpose of " Shared Worlds " fromULP, is to offer a virtual space allowing exchange between Net surfers. It allows you to explore various spaces, to meet other visitors in them... Current worlds are of an artistic nature, but they can be any type. And interesting feature of this project is the shared user viewpoint (or camera) that allows a user to be guided by another user.

• Platforms:
• Win 9x/NT

A new experiment in cyberspace, VNet uses Java to turn the vrmLab into a multi-user VRML scene, complete with avatars and chat. A normal Web browser with a normal VRML plugin is all you need to experience a 3D social space.

Server type:
• Source Code: Java

Worlds' scaleable WorldsServer™ architecture offers unique flexibility and a robust development environment for virtual world developers. WorldsServer's™ scaleable capacity and add-on module architecture provide developers the opportunity to build small prototypes that take advantage of our advanced features while keeping technology entry costs low. Developers can then easily scale their environments by augmenting server capacity as they roll out their environments, or their world popularity increases.

Using WorldsServer's™ Web-of-Worlds™ functionality, WorldsServers™ can connect to and appropriately scale interconnected virtual worlds so that large virtual worlds and large regions can be visited seamlessly by end users. Because of WorldsServer's™ dynamic downloading capability, end users can transparently move from world to world - even "walking" across server boundaries on different physical machines located in different physical locations. WorldsServer™ offers audiences powerful multi-user functionality that is easily scaleable and extensible, and the flexibility to grow their worlds as needed, with no foreseeable limit to their size.

Server type:
• Source Code: Java - C++

This code allows a number of people to enter a sharedVnet multicast world, and to communicate with others that are close in distance.
