    Some applications of computer graphics to archeology are described. One project involved making a solid model of part of the Roman temple excavated at Bath, England, and its surroundings, comprising the Temple of Sulis Minerva, its precinct with surrounding colonnade, the Facade of the Four Seasons, and the barrel-roofed bathhouse that formerly enclosed what is now called the King's Bath. This mod... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (603 KB)

    The development of computer graphics products and the growth of the market for those products during the 1980s are reviewed. It is asserted that the market can sustain at least 10%-per-year dollar volume growth over the next five years, and it is estimated that US supplier shipments will exceed $40 billion by 1995, with the highest growth coming from software and systems, closely followed by works...

    Nonuniform rational B-spline (NURBS) curves and surfaces, which are based on rational and B-splines, are defined. The important characteristics of NURBS that have contributed to their wide acceptance as standard tools for geometry representation and design are summarized. Their application to representing conic sections and commonly used surfaces, designing curves and surfaces, and modifying shape... View full abstract»

    A modified formulation of oriented boxing called oriented slab boxing is presented. It almost doubles the speed of the oriented boxing component in B-spline intersection. The method used to accelerate B-spline intersection includes algorithmic improvements and parallelization of the algorithm at different levels of granularity to find an optimum solution on a network of parallel processors. The so... View full abstract»

    The use of two sampling methods, the precise point-sampling algorithm and the extended Bresenham algorithm (EBA), for rendering hardware is discussed, showing where the two methods converge and diverge. Two antialiasing techniques are then presented: an oversampling method and a stochastic method. Practical application of both is described. The use of filtering and sophisticated features with thes... View full abstract»

    A method is presented whereby, given a mathematical description of a function, a conic spline approximating the plot of the function is produced. Conic arcs were selected as the primitive curves because there are simple incremental plotting algorithms for conics already included in some device drivers, and there are simple algorithms for local approximations by conics. A split-and-merge algorithm ... View full abstract»
