  ::

    Applies the Volume mayavi module to the given VTK data

  source (Mayavi source, or VTK dataset).

  Note

  The range of the colormap can be changed simply using the vmin/vmax parameters (see below). For more complex modifications of the colormap, here is some pseudo code to change the ctf (color transfer function), or the otf (opacity transfer function):

      vol = mlab.pipeline.volume(src)

      # Changing the ctf:
      from tvtk.util.ctf import ColorTransferFunction
      ctf = ColorTransferFunction()
      ctf.add_rgb_point(value, r, g, b)  # r, g, and b are float
                                         # between 0 and 1
      ctf.add_hsv_point(value, h, s, v)
      # ...
      vol._volume_property.set_color(ctf)
      vol._ctf = ctf
      vol.update_ctf = True

      # Changing the otf:
      from tvtk.util.ctf import PiecewiseFunction
      otf = PiecewiseFunction()
      otf.add_point(value, opacity)
      vol._otf = otf
      vol._volume_property.set_scalar_opacity(otf)

  Also, it might be useful to change the range of the ctf:

      ctf.range = [0, 1]
