However, I am unsatisfied with the quality of the images that are generated and would like to do something about it. Could you please give me advice in which direction to go?
* The postscript export of GL graphics (especially in 3D) has some severe issues (bugs #44181, #45137), which makes the exported vector graphics useless and creates problems during conversion to rasterized formats.
* The postscript export of Gnuplot looks very promising, because it contains correct polygons which can easily (depending on their number) be edited. But there are also problems to solve with unwanted/missing lines, and—the biggest issue—the z order of some polygons is wrong, which also appears on screen.
* The png images are created by conversion of a postscript(?) intermediate format. Why are rasterized images not directly rendered with the GL backend.
* The kludge: I could use screenshots of the figure windows. At least they show a correct figure (with low resolution).
I have no GL programming knowledge so far, and the gnuplot backend seems to be deprecated. Is there anything useful I could do about above problems?
