Comment (by jdemeyer):
Further analysis points to this `if` switch in
`src/sage/plot/plot3d/base.pyx` in the `_rich_repr_jmol()` function:
{{{
if not jdata.is_jvm_available():
# We can only use JMol to generate preview if a jvm is
installed
from sage.repl.rich_output.output_graphics import
OutputImagePng
tachyon = self._rich_repr_tachyon(OutputImagePng, **opts)
tachyon.png.save_as(preview_png)
else:
# Java needs absolute paths
# On cygwin, they should be native ones
scene_native = scene_zip
import sys
if sys.platform == 'cygwin':
from subprocess import check_output, STDOUT
scene_native = check_output(['cygpath', '-w',
scene_native],
stderr=STDOUT).rstrip()
script = '''set defaultdirectory "{0}"\nscript
SCRIPT\n'''.format(scene_native)
jdata.export_image(targetfile=preview_png, datafile=script,
image_type="PNG",
figsize=opts['figsize'][0])
}}}
So the problem only occurs if Java is installed.
But this leaves the question: if Tachyon works, why not always use Tachyon
to produce the plots?
