These extensions allow for hierarchical segment organization. The ability to edit existing segments is included.

A set of useful functions is designed and used in a series of illustrative examples written in the functional programming language HOPE. A functional animation system incorporating these ideas is then discussed.Item Metafile Standards(Blackwell Publishing Ltd and the Eurographics Association, 1984) Osland, C.D.; Francis, A.H.Item Computer Graphics Education(Blackwell Publishing Ltd and the Eurographics Association, 1984) Turk, SItem EUROGRAPHICS Application Form for Institutional Membership(Blackwell Publishing Ltd and the Eurographics Association, 1984) Watkins, H.Item Letters(Blackwell Publishing Ltd and the Eurographics Association, 1984) Gangnet, M.Item The Winchester Graphics System: A Technical Overview(Blackwell Publishing Ltd and the Eurographics Association, 1984) Heywood, T R; Galton, B N; Gillett, J; Morffew, A J; Quarendon, P; Todd, S J P; Wright, W VThis paper gives a technical overview of the Winchester Graphics System. It concentrates on the software system, and in particular, the use of a relational database (PRTV). The main use of the system is in scientific research and it has been used a great deal in Chemistry, Biophysics and related sciences. However, the facilities are general and the same system is used for quite different applications. such as engineering and archaeology. This database has been found to provide researchers with a powerful flexible tool and has helped the UKSC to provide an environment where new ideas can be proposed and evaluated quickly and easily.Item An Algorithm for Determining the Intersection of Two Simple Polyhedra(Blackwell Publishing Ltd and the Eurographics Association, 1984) Szilvasi-Nagy, M.An algorithm is presented for the construction of the intersection of two simple possibly non-convex polyhedra. The methods of descriptive geometry are applied, so that this three-dimensional problem can be solved in two dimensions.We have to find all intersections of the edges of each polyhedron with the faces of the other, and these points of intersection can be found in Monge’s model. Projecting both polyhedra on the xy and on the xz coordinate planes we obtain two superimposed maps in both projections. The algorithm to find the intersection of two maps is based upon the Shamos-Hoey, the Bentley-Ottmann and the Nievergelt-Preparata algorithms. The asymptotic time requirement for determining the polygon of intersection of two polyhedra is O((N + S)log N), where N is the sum of the numbers of vertices of the two polyhedra and S is the total number of intersections of all projected edges in the xy-plane (S = O(N2)).Item EUROGRAPHICS 2nd UK Conference(Blackwell Publishing Ltd and the Eurographics Association, 1984) Kidd, Ruth MItem Report on the 7th Meeting of ISO/TC97/SC5/WG2 - Computer Graphics June 1984(Blackwell Publishing Ltd and the Eurographics Association, 1984) R Gallop, JItem GKS in Pascal(Blackwell Publishing Ltd and the Eurographics Association, 1984) Slater, M.The design of the Pascal interface to the Graphics Kernel System is discussed and illustrated. The principles underlying the binding are given and examples show how some of the major features of GKS will look in Pascal. The examples cover graphical output, setting primitive representation, graphical input and inquiries.
