Some graphic systems in nuclear field

In this report outlines of four systems for computer graphics are presented. These are (i)software and hardware system for color graphic movie, (ii)JGSP, a standard software interface library for various types of graphic terminals, (iii)GRASYS, a graphic package for two dimensional display of components of nuclear power plants, and (iv)CATS, a software package for computer aided tracing of graphs, mathematical formulae, English and Japanese sentences. The first system has been developed at Power Reactor and Nuclear Fuel Development Corporation and others are developed at Japan Atomic Energy Research Institute. Although some of the systems are still in development phases, it will be helpful for researchers and engineers who have concerns in design and use of similar systems to report the design concepts and techniques adopted in these systems.
