An algorithm for piecewise linear approximation of implicitly defined two-dimensional surfaces. (English) Zbl 0618.65006

An algorithm is described for piecewise linear approximation of implicitly defined two-dimensional surfaces. The fundamental ideas of piecewise linear approximation for vector labeling are presented. An error estimate for the vector labeling approximation of smooth maps is given. The authors formulate the algorithm in terms of ”pseudo-PASCAL”. Sample numerical examples with computer graphical output are given.
