[en] In recent years the emergence of powerful graphics workstations at low cost has provided a suitable hardware platform for running large application programs in a local or networked environment and developing interactive plant simulators. The IsoVu software system has been developed to provide both the graphical functions for post-processing analysis data, and the user interface for simulators. It allows engineers to carry out tasks, which had been either prohibitively expensive or time consuming. IsoVu consists of three modules - the Display Builder, the Passive Module and the Programmers' Library. These are described and applications in the nuclear industry are indicated. (author)

[en] An alternative colour system has been developed for the EMI scanner incorporating a sixteen colour table with a selection of scale manipulation facilities. Features such as colour deletion and colour of interest pulsation are included and the output is available both in RGB (red, green, blue) form and PAL (phase alteration line by line) coded composite video form (625 line interlaced) to facilitate the use of a domestic television receiver. A digital processing unit, implemented in SSI (small scale integration) and MSI (medium scale integration) logic, is interfaced to the independent viewing centre frame buffer memory. The unit is housed in a 19 inch cabinet on five standard Eurocards with three modular power supplies. The front panel provides a selection of switch options effecting instantaneous changes in the display. Digital information is processed in real time so that normal window and level variations are tracked by the colour display. The cost of the complete system was about Pound1800 and of this, Pound1000 was absorbed in the selection of a high quality RGB monitor (Sony PVM1300E). (author)

[en] In this paper some aspects of graphic display systems are discussed. The design of a display subroutine library is described, with an example, and graphic dialogue software is considered primarily from the point of view of the programmer who uses a high-level language. (Auth.)
