The book is written on the basis of a course of lectures given by the authors. The main classes and functions of the Delphi environment, which are used to create graphic and multimedia applications, are considered. Color models, the main formats of graphic files, as well as methods for constructing curves in interpolation, smoothing, approximation problems, Hermite, Bezier and B-splines methods are described. Algorithms for triangulation of surfaces in three-dimensional space are given.
