A CAGD method for elliptic cross sections of circular parabolic quadrics. (English) Zbl 0948.68201

A computer aided geometric design method is developed to obtain a very fast and figh-quality construction of the elliptic cross-section between a conus and a plane, and between a cylinder and a plane. This method uses algebraic equations for defining the positions of the points. The method makes possible to separate the visible and invisible lines of the picture that gives a good vision of a thee-dimensional body. The mathematical relations are implemented in a Turbo Pascal program.
