Giovanni,
I don't remember exactly the messages where this was discussed. You may
google in mathgroup for 'large pdf' or consider the package
'FixPolygons' on http://library.wolfram.com/infocenter/MathSource/7029/.
After applying FixPolygons onto your graphic, you can export it the
usual way, giving smooth pdfs of moderate size. But the .eps files are
still huge. The processing of FixPolygons needs some time (about 5 to 10
minutes on my G5)
