After a short presentation of the two graphics standards and the X Window System, the impact of realizing PHIGS or GKS-3D in a Window environment is described. For output, a graphics workstation must use the X 2D graphics elements and an X window as display surface. For Input, the X event queue will be used and must be controlled by a separate process. The usage of the PHIGS PLUS extensions leads to three possible solutions for transferring data over the network: usage of pixel maps, usage of X 2D graphics or usage of X extensions. A comparison to the PEX (PHIGS PLUS Extension to X) protocol proposal will be made. The usage of X together with graphics standards leads to network-wide distributed graphics applications.
