When I define a variable myfig as a Graphics3D object rendered with a specified ViewPoint, the graphic is properly rendered onscreen, but in some cases when Exported (Export[...myfile.eps, myfig, "EPS"]) the .eps image shows the graphic from another (default) ViewPoint. How can one force the ViewPoint to be preserved during Export?

    $\begingroup$ Often things like this can be done my explicitly passing the argument to Export (sometimes needing to be first converted to a string). Does that work? $\endgroup$ – b3m2a1 Mar 29 at 1:04
  • $\begingroup$ I don't quite understand your recommendation. I define myfig = Graphics3D...], then on the next line Export[..., myfig, "EPS"]. Is there some trick with $DisplayFunction I'm missing? $\endgroup$ – David G. Stork Mar 29 at 1:07
  • $\begingroup$ Hmm actually I'm not able to reproduce your issue just with regular Export. Can you provide an example that fails for you? $\endgroup$ – b3m2a1 Mar 29 at 1:10
  • $\begingroup$ Alas, the code is long and complicated. I think I'm revealing everything necessary in my posting. Thanks for considering this. My workaround (when it happens) is to hand copy the display cell (in proper ViewPoint), then define a new variable and paste the image as its referent, and then Export that new variable. That works. $\endgroup$ – David G. Stork Mar 29 at 1:56
  • $\begingroup$ What were you trying instead? Were you exporting the cell? I only imagined exporting a Graphics3D expression $\endgroup$ – b3m2a1 Mar 29 at 2:21

The current ViewPoint of the 3D-graphics drawn in FrontEnd can be easily obtained by following (sorry, I put it as image but it is more clear):

enter image description here

{ViewPoint -> {0.772292, 1.91213, 2.68278}}

You will have always the new VP if you move somehow the graphics and after evaluate the cell again.

Therefore, you can Export your Graphics3D with manually adjusted ViewPoint just adding the defined VP into the definition of your Graphics3D explicitly.

  • $\begingroup$ Perfect. Thanks so much. (I should have known that.) (accept $\checkmark$) $\endgroup$ – David G. Stork Mar 29 at 7:55
  • $\begingroup$ @DavidG.Stork, Actually I don't know is it feature or bug of modern versions of MMa. The old versions have the ViewPoint selector in top menu but the new don't. $\endgroup$ – Rom38 Mar 29 at 8:03
