“…The time for the operator to interact with the process via displays and controls is sometimes very short and, therefore, fast picture changes with fast and easy information access are necessary to register process changes. Use of the graphics standards GKS (Bono et al 1982;Bono 1985;X3.124 1985) and CORE is not efficient in our application domain, because these standards do not allow direct access to the display lists necessary for manipulating the display list content. The optimal manner of manipulating graphical information can be achieved through direct access to the display list (where the display content is saved).…”

The process visualization system of a manmachine interface is presented. It allows human operator(s) to interact with a dynamic technical system, here a thermal power plant. Also, a graphical editor for designing dynamic pictures of the process visualization system is explained. Both new systems have a common architecture and are based on the computer graphics standard PHIGS-2D with extensions for handling non-graphical and graphical information. The hierarchical information structures are manipulated with lists and pointers in a dynamic visual database. The two menu-driven interfaces for designers and for operators are described with their multi-window display layouts. The software of both systems is highly portable to different hardware and to other application domains.

“…Its major fault lies in its performance, wit h a hard disc nearly mandatory for program development (Bono, 1985) . It has bindings t o various programming languages but a Pascal implementation is problematic for variou s reasons (Antoy & Dettori, 1983) .…”

INTRODUCTIONMany departments of higher education have bought microcomputers with which to teach thei r introductory courses in program design and development . They have many advantages i n comparison with main-frame and mini-computers : simple-to-understand operating systems , full-screen editors, good response times and, in many cases, colour graphics . Th e student response to using microcomputers is, on the whole, very positive, an d particularly so when programming projects are introduced which use interactive graphics . The use of graphics often motivates the students to produce more imaginative and comple x programs .Graphics is also a very good vehicle for developing a deeper understanding of numerou s topics in science such as population genetics, molecular structure, kinetics, mathematic s and statistics . When used by arts students, it has the same stimulating effect, althoug h for different reasons . In the humanities and arts-based subjects graphics is seen as a way of presenting information in a visual form which greatly increases the effectivenes s of man-machine communication . The importance of graphics in man-machine interaction i s amply demonstrated by the latest developments in microcomputer operating systems a s illustrated by Apple's Macintosh, Digital Research's GEM, and Microsoft's Windows (Swain e 1985) .We have, over the past four years, taught an introductory course in Program Design t o students who are not reading for a computing degree, but who wish to use computing as a tool in their main subjects which range right across the entire spectrum of Highe r Education, including Physics, Geology, Maths, Geography, Psychology, English, French , History and Philosophy . In just this short time span we have used six different model s of microcomputer : RML 380Z, RML 480Z, Victor/Sirius, Apricot PC, Apple Macintosh and R M Nimbus . All machines have a graphics capability, but each has offered a very differen t library of graphics routines . This has meant that the staff have to become proficient i n five different graphics systems, that program examples have to be substantially modifie d for each machine, and that students going on to a second year course have to learn a ne w set of graphics routines . Some might argue that learning more than one system of graphics would be beneficial t o the students, but the educational aim of our courses is not to teach graphics, but t o teach the principles of program design and development . We needed a graphics standar d that was the same for all our microcomputers (as far as the hardware would allow), an d that was quick and easy to learn and use, so that students could concentrate o n developing and designing the program, and would not have to spend too long in grapplin g with an inconsistent and arbitrary set of graphics primitives . Unfortunately there is a variety of very different graphics standards due to the problems outlined by Hopgoo d (1985) . EXISTING de facto STANDARDSIn principle the graphics standard proposed could be implemented for an...
