Abstract
We describe the Scene-Graph-As-Bus technique (SGAB), the first step in a staircase of solutions for sharing software
components for virtual environments. The goals of SGAB are to allow, with minimal effort, independently designed
applications to share component functionality; and for multiple users to share applications designed for
single users. This paper reports on the SGAB design for transparently conjoining different applications by unifying
the state information contained in their scene graphs. SGAB monitors and maps changes in the local scene graph
of one application to a neutral scene graph representation (NSG), distributes the NSG changes over the network
to remote peer applications, and then maps the NSG changes to the local scene graph of the remote application.
The fundamental contribution of SGAB is that both the local and remote applications can be completely unaware
of each other; that is, both applications can interoperate without code or binary modification despite each having
no knowledge of networking or interoperability.
