OK, I've checked in a fix to make this easier. Here is an example:
# ------ vol.py -----
mayavi.new_scene()
from enthought.mayavi.sources.vtk_file_reader import VTKFileReader
s = VTKFileReader()
s.initialize('/tmp/t.vtk')
mayavi.add_source(s)
from enthought.mayavi.modules import volume
v = volume.Volume()
volume.load_volume_prop_from_grad('/tmp/junk.grad',
v.volume_property,
(0.0, 1.0))
mayavi.add_module(v)
volume.save_volume_prop_to_grad(v.volume_property, '/tmp/test.grad')
# ------ vol.py -----
Again, run this as mayavi2 -x vol.py and it should work and is a lot
easier to use.
HTH.
cheers,
prabhu
