Describes a set of functions for computer graphics programming, the Programmer's Hierarchical Interactive Graphics System (PHIGS). PHIGS is a graphics system for application programs that produce computer generated pictures on output devices. Pictures are displayed on workstations consisting of a single output device and a number of input devices. Several workstations can be used simultaneously. The application program is allowed to adapt its behaviour at a workstation to make best use of workstation capabilities. An interface to the Computer Graphics Metafile (ISO 8632) is described. An extensive detailed standard of 64 pages.
