I use the visual API, so basically I create all the cylinders that I
need directly with the code shown above (the second line, basically),
passing the coordinates and the scalar for the axis, basically
setting, x,y,z and axis as keyword.
According to the CylinderClass DocString:
Docstring:
Cylinder class creates Cylinder from tvtk CylinderSource,
follows the usual VTK pipeline and creates a Sphere actor, which
is passed to the show_actor() function as an argument.
I think the magic happens there, because I don't create the actor
myself, but all that is already taken care in the visual code.
Check out this functions:
def _create_viewer():
https://github.com/enthought/mayavi/blob/master/enthought/tvtk/tools/visual.py#L80
def show_actor(*tvtk_actors):
https://github.com/enthought/mayavi/blob/master/enthought/tvtk/tools/visual.py#L116
Maybe the data should be plugged in over there?
Cheers,
Michele
