Re: 3d EPS export files huge on Mac OS X, not so much on PCs

EPS is a vector format which means that the files contain instructions 
for drawing an image instead of coordinates with associated colors as 
with raster figures (eg: bmp, tiff, png, jpg).  The problem is that EPS 
doesn't render 3D graphics, so Mathematica is left with two options:
1) embed a raster into the EPS, or
2) generate a sequence of vector graphics commands that draws the 
projection of the 3D image.
For some reason your PC is choosing option 1 and your mac is choosing 
option 2, which yields large files.

The function Rasterize will force Mathematica to choose option 1 before 
you even export the figure.
The problem is that axes labels will also be rasterized instead of 
embedded as fonts.  Here's a tutorial on how to get the best of both:
