def visualize(self, color=(0.5, 0.5, 0.5), style='surface', opacity=1.0):

Parameters
----------
color : :obj:`tuple` of float
3-tuple of floats in [0,1] to give the mesh's color
style : :obj:`str`
Either 'surface', which produces an opaque surface, or
'wireframe', which produces a wireframe.
opacity : float
A value in [0,1] indicating the opacity of the mesh.
Zero is transparent, one is opaque.
Returns
-------
:obj:`mayavi.modules.surface.Surface`
The displayed surface.
