A Two-Space Solution to the Hidden Line Problem for Plotting Functions of Two Variables
Thomas J. Wright · IEEE Transactions on Computers · 1973
A fast algorithm for eliminating hidden linies from perspective representations of single-valued functions of two variables is presented. Compared with the most widely used algorithm for this problem, the algorithm presented here is as versatile, but much faster. Compared with a recently published algorithm for this problem, the algorithm presented here is more powerful and as fast. Compared with more general algorithms, the one presented here is much less complicated, since this algorithm is tailored to this problem.
