If you use the updated VTK-Python zip file that is available here:


then gl2ps support should be available.  The new MayaVi-1.5 installer
does have gl2ps support.  The above zip file is made using Enthon's
latest VTK dlls.  Earlier versions did not support gl2ps but the one I
sited in my previous mail does support gl2ps.  So, if you install this
version of VTK and then save a mayavi image via gl2ps (there is a menu
option for this) you should get vector EPS/PDF output.

By default vtk's gl2ps exporter dumps every primitive that it can (it
can't do image actors though) as a vector graphic.  However for
complex visualizations you can turn on the 'Write3DPropsAsRasterImage'
on then all 3d primitives are dumped as an image and all 2d primitives
(like text) will be rendered as vector graphics.  For example, try
gl2ps on the heart.mv example.  It will take a while to write but
should work.
