Sorry for the extremely delayed response. Here is a simple script
that shows you how. It is a bit of a pain and I'll check in something
that makes it easier but here is something that works:
# ---- vol.py -----
mayavi.new_scene()
from enthought.mayavi.sources.vtk_file_reader import VTKFileReader
s = VTKFileReader()
s.initialize('/tmp/t.vtk') # Replace with your datafile.
mayavi.add_source(s)
from enthought.mayavi.modules.volume import Volume
from enthought.tvtk.util.gradient_editor import GradientTable
gt = GradientTable(300)
gt.load('/tmp/junk.grad') # Replace with your gradient file.
v = Volume()
gt.store_to_vtk_volume_prop(v.volume_property, (0.0, 1.0))
mayavi.add_module(v)
# ---- vol.py -----
Just run this like so:
mayavi2 -x vol.py
This should do the job.
The trouble with discovering how to do this is that mayavi2 itself
saves something different and not the .grad file. So I hadn't
bothered adding the functionality to load the grad file from a script.
I'll check something in to fix this shortly.
cheers,
