It may be difficult to include glossiness/shiny surfaces by programs (a recent compilation) into true vector formats.
Assuming you want to use the illustration for a poster, or a publication in a journal, determine the dimension of the illustration intended (e.g., how many centimetres or inches is the width of a single column). With 2.54 cm = 1 in in mind, determine the the number of pixels in this direction with the minimal resolution (dpi) set by the publisher (an example). Say, the figure is for a column of 8.85 cm (as by above style sheet); divided by 2.53 this equates to 3.48 inches, and if the minimum resolution is 400 dpi, the image to be prepared should be 1394 pixel wide.
The best approach now is to generate an illustration this wide. If the intermediate format e.g., is
.pov of povray, you may adjust these dimensions of the illustration to be rendered. If it is a vector illustration (true
.pdf), you may scale this in e.g., inkscape and save it again (rescaled) in the format (preferentially again as vector file).
