In this paper we propose a computer-graphics based Decision Support System for multiple objective linear programming that builds on the VIG system (Visual Interactive Goal programming). The essential part of the VIG system is Pareto Race, a dynamic and visual approach for exploring the efficient frontier of at multiple objective linear programming problem. Our objective is to extend Pareto Race to large-scale multiple objective linear programming. The approach works with any efficient, solutions that are in general not extreme point solutions. Interactive use of computer graphics plays central role. The approach, the underlying theory, and an illustrative example are described.

An interactive computer graphic system is described for the analysis and modeling of sign language movement. This system consists of four components. The first component reconstructs actual movements in three dimensions and allows the user to interactively create synthetic signs by specifying angle functions in a jointed model. The third component provides a novel technique for manipulating movement quality independently of spatial path. The fourth component allows the building of complex stimuli and real-time stimulus sequencing for psycholinguistic experiments. The emphasis is on interactive techniques and data structures that allow analysis and modeling of complex hand and arm movements of American Sign Language.

Digital hard copy systems must be capable of reconstructing any image on a substrate with one writing instrument. The need for high speed suggests technologies where mass does not move with the information to be displayed. Several technologies are described that meet these requirements. They include thermal, ink-jet, xerography and electrostatic writing.

The key role played by computer graphics in urban, regional, and environmental information systems is surveyed by reference to specific examples. While the interactive cathode-ray tube terminal is found to be the most valuable medium, other output devices such as printers and plotters are discussed as well. Elements of computer cartography and data base organization are introduced, followed by discussions of urban information and transportation network design systems, a regional analysis system, and air and water quality information systems. Specific recommendations are given for further research in data base design and display techniques, and for promising new hardware for use in geographically distributed data systems.

The opportunities for applying coomputer graphics and com puter-aided design (CAD/CAM) to switchgear engineering drawings are examined in a case study of one switchgear manufacturer's computer system. This system is of unusual interest because it is particularly strong in two features which are seldom achieved: 1) flexibility in drawing layout and content, and 2) greater computer assistance in most steps in producing engineering drawings. An explanation of the choices, and capabilities in computer- aided design systems for switchgear is presented. In addition, guidelines in designing or choosing a system that allows flexibility and maximum computer assistance in producing the drawings are noted.

Hydroxyapatite (HA) and .beta.-tricalcium phosphate (TCP) were studied by computer graphics with a personal computer. Crystal models of fluoridated hydroxyapatite and fluorapatite, in which F- ions are substituted into some or all OH- positions, were also drawn. Data on the structural coordinates of the hydroxyapatite and .beta.-TCP crystals were put into a protein graphics program in Angstrom units. The connection of each element, with front and rear, was displayed by the shade-line erasing method, and the solidity of the image was expressed by the degree of lightness from the light source. The colour tint was obtained by the Raster graphics method. A fine picture can be obtained with the photo program. Rotating the graphics freely around the X, Y, and Z axes gives a view from any direction. The computer graphics demonstrated visually that F- ions contribute to stabilize the hydroxyapatite crystal and that .beta.-TCP has an unstable structure due to 0.5 probability of Ca2+ ions and [PO4-Ca-Ca-Ca-PO4] zigzag chain.
