I have been testing it with gl2ps-1.2.0. Works well.
With your new version I definitely see some improvements.
The surface in the postscript image that was coming out
semi-transparent before (see above) is now opaque as it
is in the OpenDX viewer. I'm not sure if the lack of
transparency led to a smaller filesize but the postscript file
is now 5 mb (vs 90 mb before!).
I am having less succes getting the PlotPostscript to actually
produce a non-blank postscript file though. The success rate
is much less (say 25%) than before.
I'm not sure if this is because I used gl2ps-1.2.0, but I am getting
an error/warning in the Message Window:
GL2PS info: OpenGL feedback buffer overflow.
This didn't happen with your older version of PlotPostscript even
though I was using gl2ps-1.2.0 before also. I only get this warning
with a large/complicated image.
Finally, again possibly due to the version of gl2ps I used, I
find that the "no sorting" option is not allowed.
Still, it is great module. Thanks.
