virtual reality transfer protocol (vrtp)
vrtp is being developed to provide client, server, multicast streaming and network-monitoring capabilities
in support of internetworked 3D graphics and large-scale virtual environments (LSVEs).
A large number of network software architectures for 3D graphics virtual environments have been proposed. Most share a large number of characteristics, but remain mutually incompatible and unable to utilize the necessary network services across the full Internet. vrtp is intended to provide the client, server, multicast peer-to-peer streaming and network monitoring services needed for large-scale virtual environments (LSVEs).
vrtp is expected to support networked interaction with a variety of 3D technologies. Thus vrtp is an appropriate area of effort for a Web 3D working group. Additional detail is described under the Motivation section of the vrtp home page.
A great deal of previous and related work is described throughout the vrtp home page.
The dis-java-vrml working group produced a software prototype for the vrtp streaming stack.
Don Brutzman is the principal investigator of the vrtp research project.
Collaboration by other institutions and individuals is welcome.
All software contributions and products will be open source. We expect to follow the recommendations of the Intellectual Property Rights working group.
The vrtp project was conducted by NPS with a variety of research collaborators during 1995-1998. We are now transitioning to an open working group.
Project technical status is maintained on the vrtp home page.
Mailing list information will be provided when the working group meets all neccessary prerequisites and has been approved by the Web3D Consortium.
