Re: [Visualpython-users] EPS output with gl2ps

[Bruce S. <Bru...@nc...>]

I was unable to read the eps files into Adobe Illustrator, which hangs. 
Something is wrong with the format (or with Adobe Illustrator).

The quality of the image is basically defined by the number of triangles 
VPython chooses to use to create spheres, etc., so that at ordinary 
sizes I see little difference between the screen capture and the pdf (I 
was unable to view the eps version), though of course when I blow up the 
pdf by a large factor it doesn't get more jagged as the screen capture 
bitmp image would.

The export to Pov-Ray using the module available at vpython.org produces 
much better final images, because the image is ray-traced and doesn't 
depend on the triangles used to render the VPython scene in real time.
