Open Cobalt is a free and open source software platform for constructing, accessing, and sharing virtual worlds both on local area networks or across the Internet, without any requirement for centralized servers. The technology makes it easy to create deeply collaborative and hyperlinked multi-user virtual workspaces, virtual exhibit spaces, and game-based learning and training environments that run on all major software operating systems. By using a peer-based messaging protocol to reduce reliance on server infrastructures for support of basic in world interactions across many participants, Open Cobalt makes it possible for people to hyperlink their virtual worlds via 3D portals to form a large distributed network of interconnected collaboration spaces. It also makes it possible for schools and other organizations to freely set up their own networks of public and private 3D virtual workspaces that feature integrated web browsing, voice chat, text chat and access to remote desktop applications and services. Open Cobalt uses the Squeak software environment, which is an open source Smalltalk system freely available for Windows, Mac and Unix. As is true of almost any Smalltalk application, Open Cobalt has identical functionality on any supported platform. As a Smalltalk system, it can usually be updated while the system is running without requiring a restart. ==Expected uses== Open Cobalt is designed to enable the deployment of secure virtual world spaces that support education, research, and the activities of virtual organizations. By leveraging OpenGL-based 3D graphics, Open Cobalt supports highly scalable collaborative data visualization, virtual learning and problem solving environments, 3D wikis, online gaming environments (MMORPGs), as well as privately and securely maintained multi-user virtual environments. The Open Cobalt application leverages peer-based messaging to eliminate the need for virtual world servers/commercial services and makes it very simple for end-users to create and securely share deeply collaborative virtual worlds that run on all major software operating systems. Users moving through and interacting within Open Cobalt worlds simultaneously participate and collaborate in a dynamic, concurrent environment where they can work, explore, and learn at a level of integration and extensibility not easily achieved through commercial virtual world technologies. Without any licensing fees, users and developers can also freely build and share highly capable multi-user virtual workspaces, game-based learning and training environments, or even just create places to meet and interact with friends. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Open Cobalt」の詳細全文を読む スポンサード リンク
