    The overall feasibility of 3-D color imaging is determined, taking into account display method, display options, and image processing system. The method is based on the display of 3-D colored ranges of data values and allows very complex convoluted structures with disjoint parts to be imaged. This approach results in a very fast, interactive method for interpreting the position, size, and shape of... View full abstract»

    A representation for arbitrary C1 surfaces, using biquadratic patches, is described. The key to this simplification is the introduction of extra knots into the system. Using this representation, the polynomial equation for ray tracing is at most eight degree, in contrast to bicubic, which leads to an eighteenth degree polynomial. The scheme was implemented in the SynthaVision system, wh... View full abstract»

    The midpoint algorithm for drawing ellipses on raster graphics displays is presented. The algorithm is highly accurate and requires only a few integer additions per pixel. It is also demonstrated that a simple extension of J.E. Bresenham's circle-drawing algorithm (1965) to the more general case of ellipses is not sufficient to guarantee accuracy. The accuracy of the midpoint algorithm is limited ... View full abstract»

  • Offsets of Two-Dimensional Profiles

    The implementation of an offset capability for planar curves and profiles in a solid modeler is discussed. A curve is assumed to have a continuous tangent vector, and a profile is defined to be a composite curve, possessing only positional continuity. Algorithms are presented for offsetting both entities. A practical design problem, the solution of which makes use of the offset capability, is pres... View full abstract»

    Given two surfaces in three-dimensional Euclidean space R3, specified by two twice continuously differentiable functions f(p)=0 and g(p)=0, where p denotes a point in R3, the authors construct a third-order autonomous system of ordinary differential equations (ODEs), p'=Z(p), using the gradients of f and View full abstract»
