A Shared 4-D Workspace

A Shared four-dimensional workspace is a shared animation of three-dimensional databases. Since shared animated workspaces are important to many different types of users, a pilot project was undertaken to implement a shared, time varying workspace. This software permitted the give and take of control by users running the same application across an ATM fiber link running at 100 mbits/sec. The project was divided into two parts. In the first phase, animation of three-dimensional databases in stereo was implemented. In the second phase, sharing of the animation across the ATM network was added. This paper dicusses the interfaces to the program and presents outlines of implementations of the features in each of the project's two phases.
