You can use img=__osmesa_print__(gcf), imwrite (img....) to directly
render the OpenGl scene without going through gl2ps.

Helpful to note that this only works with: h = figure ("visible", "off");


Thank you. The __osmesa_print__ segfaults on my dedicated graphics card, but works with the Intel chip. The result seems to have no anti-aliasing, however I can easily use a FSAA filter.
You could also try setting the environment variable: LIBGL_ALWAYS_INDIRECT=1
This forces use of graphics software. But, if you have it working probably best not to
use more time on experiments.
