Package: mayavi2
Version: 3.3.0-1
Severity: normal
Hi!
This bug could be caused by vtk: please reassign, if appropriate.
Steps to reproduce:
$ mayavi2 -d /usr/share/doc/mayavi2/examples/mayavi/data/heart.vtk
The main window shows up.
* select Add module or filter in the Mayavi pane
* from the Mayavi object editor, choose IsoSurface
* rotate and zoom the visualization, until it looks "pretty" enough
* from the File menu, select Save Scene As > Vector PS/EPS/PDF/TeX
* in the dialog window, enter "foo.pdf" as Name
* click on the Save button
* in the next dialog window, accept default GL2PSExporter properties
(OK button)
Then try to display the resulting file:
$ xpdf foo.pdf
$ gv foo.pdf
After an fairly long wait, the PDF file is shown, but with large
parts of the iso-surface painted black, rather than green.
I've also tried to use non-default GL2PSExporter properties:
a) disabling "Draw background" leads to the same issues
b) disabling "Ps3 shading" doesn't seem to help
c) choosing "simple" Sort doesn't help either
d) disabling "Occlusion cull" seems to slow down even more xpdf, but
not gv (without fixing the black areas issue)
e) disabling "Best root" does not help
Please note that saving the scene as a PNG image works as intended
(but obviously generates a raster image, not a vector one!).
