Does anyone know of a public domain hidden line removal suitable for
plotters (yes, it's still 1964 here)?  All the ones I have are either
for rasters (use scan-line coherence) or assume regularity in the X-Y
plane.  I'd like one based on Atherton's algorithm or something like that.

Thanks,
Chuck Hansen
