pp: 14-26
ABSTRACT
<p>A description is given of PEX, an extension to the X Window System that is designed to efficiently support PHIGS and much of the functionality in the proposed PHIGS+extension to PHIGS PEX (PHIGS, PHIGS+, and Extensions to X) allows each window on the display to act as a complete, independent, virtual 3D graphics workstation. The overall architecture of PEX is examined, with emphasis on how it fits into the network environment of X. The history of the PEX effort and the problems that motivated it are discussed. The major features of PEX are presented, and the tradeoffs that were evaluated during the design process are examined. The remaining open issues and their current status are described.</p>
