Item UK Chapter of the Eurographics Association(Blackwell Publishing Ltd and the Eurographics Association, 1984)Item Report on Dialogue Specification Tools(Blackwell Publishing Ltd and the Eurographics Association, 1984) Green, MarkIn this report we have presented some of the issues pertaining to the notations used in UIMSs. At the present time there are a small number of implemented UIMSs, so there is some experience to draw upon. This is the first workshop of this nature where there has been a significant number of participants with implementation experience. This experience seemed to raise more issues than it resolved. The conclusion that can be drawn from this is there is still a considerable amount of work to be done in notations for UIMSs.One of the major problems encountered by this working group was the inability to compare different UIMSs. The systems discussed in this group have been used to produce user interfaces for different application areas, with different interaction styles and requirements. This makes it very difficult to compare the ease of use (for the user interface designer), and the quality of the resulting user interface. This problem would be partially solved by constructing a standard set of user interface problems. Each of the UIMSs could be used to solve these problems, and the results used as a means of comparison. This set of problems could be viewed as a benchmark test for user interface management systems. Along with developing the problems, techniques for measuring ease of use and the quality of the user interface must also be developed.Item From the Secretary(Blackwell Publishing Ltd and the Eurographics Association, 1984)Item Computer Art(Blackwell Publishing Ltd and the Eurographics Association, 1984) Truckenbrod, JoanItem SIGGRAPH ’84(Blackwell Publishing Ltd and the Eurographics Association, 1984) Hopgood, F.R.A.Item EUROGRAPHICS General Assembly(Blackwell Publishing Ltd and the Eurographics Association, 1984)Item Proposal for GKS Output Level 3 Segment Hierarchy and Editing(Blackwell Publishing Ltd and the Eurographics Association, 1984) Steinhart, Jonathan EThis proposal describes a set of compatible extensions to GKS. These extensions allow for hierarchical segment organization. The ability to edit existing segments is included. The paper is an excerpt from: ISO TC97/SC5/WG2/N309 / ANSI X3H3/84-57R1Item EUROGRAPHICS ’85 at the Acropolis - Nice(Blackwell Publishing Ltd and the Eurographics Association, 1984)Item Metafile Standards(Blackwell Publishing Ltd and the Eurographics Association, 1984) Osland, C.D.; Francis, A.H.Item 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.Item An Algorithm for Constructing a Quadtree from Polygonal Regions(Blackwell Publishing Ltd and the Eurographics Association, 1984) Casciani, T.; Falcidieno, B.; Fasciolo, G.; Pienovi, C.Quadtrees are a class of hierarchical data structures particularly suitable for the representation of images in a compact form. In this paper a new algorithm is described which builds up the quadtree corresponding to polygonal multiply connected regions starting from their boundary representation.Item More on Computer Graphics Metafile Coding Efficiency(Blackwell Publishing Ltd and the Eurographics Association, 1984) Schoenhut, J.Item Book Reviews(Blackwell Publishing Ltd and the Eurographics Association, 1984)Book reviewed in this article:The Computer Image: Applications of Computer Graphics by Donald Greenburg, Aaron Marcus, Allan H.
