 Dear Dr. Graether,
   another option (other than postscript) would be to write out a grasp
 file and convert it with E.A. Merritt's program ungrasp to RASTER3D objects
 then render it with the program render at any resolution you want.

 Look at http://www.bmsc.washington.edu/raster3d/examples/examples.html
 (last example).

 Hope this helps.
