Does anybody have a program which plots functions z = f(x, y) with hidden lines removed (i.e. "warped planes"). Preferably the output should be in HPGL or plot(5) format, but I'm willing to take (almost) anything. Complete programs or fragments in Fortran or C will be accepted with equal gratitude.
