Croquet Project

Résumé
The Croquet Project is a software project that preceded Croquet, and was intended to promote the continued development of the Croquet open-source software development kit to create and deliver collaborative multi-user online applications. Implemented in Squeak Smalltalk, Croquet supports communication, collaboration, resource sharing, and synchronous computation among multiple users. Applications created with the Croquet software development kit (SDK) can be used to support highly scalable collaborative data visualization, virtual learning and problem solving environments, 3D wikis, online gaming environments (massively multiplayer online role-playing games (MMORPGs), and privately maintained or interconnected multiuser virtual environments. Further development of the technology has also branched into the Open Cobalt and Open Croquet efforts. Croquet is a software development kit (SDK) for use in developing collaborative virtual world applications. Applications created using the Croquet SDK are automatically collaborative since application objects in Croquet share a common protocol allowing them to cooperate with each other by employing the principle of replicated computation (synchronization) together with a peer-based messaging protocol. The technology is designed to facilitate such replication between peers, to greatly reduce the overhead needed for widespread deployment of collaborative virtual worlds. This efficiency, combined with the ability to deploy Croquet-based virtual worlds on consumer-level hardware, makes it possible for developers to deploy large-scale and highly participatory collaborative worlds at very low cost compared with virtual world technologies that are entirely dependent on server-based infrastructures to support the activities of their users. Croquet's virtual machine (VM) runs bit identically on multiple platforms, and supports multiple abilities that could only be provided by a true late bound, message sending language.
