R. A.; Ten Hagen, Paul J.W.Item The European Association for Computer Graphics(Blackwell Publishing Ltd and the Eurographics Association, 1983)Item Executive Committee Meeting 30 August 1983, Zagreb, Yugoslavia(Blackwell Publishing Ltd and the Eurographics Association, 1983)Item Geodesic Curves on Patched Polynomial Surfaces(Blackwell Publishing Ltd and the Eurographics Association, 1983) Haw, R J; Munchmeyer, F CA method is described for tracing geodesic curves across patched surfaces. Two techniques are discussed for constructing the curves - an initial value problem and a boundary value problem. Arc lengths are computed, as well as the enclosed area of an arbitrary region on the surface.Item A Method for Choosing Tickmarks on a Nonlinear Scale(Blackwell Publishing Ltd and the Eurographics Association, 1983) Kjelldahl, L.The problem of choosing tickmarks for nonlinear scales is of interest for some kindsof diagrams, e.g., nomograms and contour plots. A method for getting "nice"values at the tickmarks is discussed based on a database of sequences. Each last digit inthe ticknumber has a set of tickmark sequences that may be used from the ticknumber. An implementation to test the method has been made.Item Raster Display of a Rotating Object Using Parallel Processing(Blackwell Publishing Ltd and the Eurographics Association, 1983) Strothotte, T.; Funt, B.Parallel processing algorithms have been developed which approach real-time in displaying raster graphics images of a single rotating three-dimensional object. The hardware required consists of a large number of individual processors with inter-processor communication restricted to immediate neighbours. The overall structure is as if the processors were spread uniformly over the surface of a sphere. The objects for display are modelled as if they were inside this sphere of processors.Each processor stores the following information: * 1) the intersection points of the object-s surface with a radial line extended from the sphere-s centre along with the surface normals at those intersection points, and * 2) pixels representing a small section of the screen.The algorithm involves an organised message-passing scheme to accomplish rotations of the object description and the subsequent display of the image. A simulation of a system involving several hundred processors indicates that its performance improves as a near-linear function of the number of processors.Item Report of EUROGRAPHICS-83 Zagreb, Yugoslavia(Blackwell Publishing Ltd and the Eurographics Association, 1983) Sweeney, Miss A; Watkins, H K.Item Report on the 6th meeting of ISO/TC97/SC5/WG2 Computer Graphics(Blackwell Publishing Ltd and the Eurographics Association, 1983) ten Hager, P J W; Straayer, David; Lewandowski, Steffen
