An Interesting Modification to the Bresenham Algorithm for Hidden-Line Solution

Abstract

The solution of many engineering problems have as a result functions of two variables, that can be given either by an explicit function description, or by a table of the function values. The functions, that can be given either by an explicit function description, or by a table of the function values. The functions have been usually plotted with respect to visibility. The subprograms for plotting the functions of two variables were not so simple ([6]–[7]) although visibility may be achieved by the relatively simple algorithm at the physical level of the drawing, if we assume raster graphics devices are used. The Bresenham algorithm for drawing line segments can be modified in order to enable the drawing of explicit functions of two variables with respect to the visibility.
