  • A Note on 3D-Clip Optimisation 

    Hubl, Josef (Blackwell Science Ltd and the Eurographics Association, 1993)
    In order to optimize the transformation-clipping-pipeline of PHIGS or GKS-3D it is sometimes necessary to determine whether a plane intersects a perpendicular volume or not. The solution to this problem is not very ...
  • The ARGOSI Classification Scheme for Graphics and Networking Applications 

    Sutcliffe, D.C.; Gallop, J.R.; Maybury, R.; Day, R.A.; Duce?, D.A.; Reynolds?, G.J. (Blackwell Science Ltd and the Eurographics Association, 1993)
    ARGOSI is a project concerned with the relationship between standards for graphics and networking, as rejected in its full title: Applications Related Graphics and OSI Standards Integration. It is a collaborative project ...
  • The Potential Equation and Importance in Illumination Computations 

    Pattanaik, S. N.; Mudur, S. P. (Blackwell Science Ltd and the Eurographics Association, 1993)
    An equation adjoint to the luminance equation for describing the global illumination can be formulated using the notion of a surface potential to illuminate the region of interest. This adjoint equation which we shall call ...
  • A Survey of 3D Solid Reconstruction from 2D Projection Line Drawings 

    Wang, Weidong; Grinstein, Georges G. (Blackwell Science Ltd and the Eurographics Association, 1993)
    The reconstruction of a 3D object from its 2D projection(s) and its corresponding problem of 3D object recognition are two of the important research areas in the field of computer vision and artificial intelligence. ...
  • Pictorial Editing by Shape Matching Techniques 

    Ventura, A. Della; Ongaro, P.; Schettini, R. (Blackwell Science Ltd and the Eurographics Association, 1993)
    A number ofpainting and retouching packages operate much like the artist s traditional canvas andpalette, with electronic toolsfunctioning like their studio counterparts. These programs, while offering an ample set of tools ...
  • A New Approach for the Generation of Circles 

    Hsu, S. Y.; Chow, Louis R.; Liu, H. C. (Blackwell Science Ltd and the Eurographics Association, 1993)
    Two incremental algorithms for drawing circles using short line segments are proposed in this paper. The proposed algorithms can draw manypoints at one time. They use only addition, subtraction, and shift operations except ...
  • PRIP - A Parallel Raster Image Processor 

    Van Campenhout, Jan M.; Lasure, Roeland (Blackwell Science Ltd and the Eurographics Association, 1993)
    Like colour video displays and laser printers, laser photoplotters are raster scan devices. For such devices, the pixel stream representing the image must be generated in real time, and in the (scan line) order required. ...
