Must contain at least ``xticker``, ``yticker`` and ``zticker``. A ``ticker`` is a dictionary which contains: - ``ticks`` (array of numbers) - required. Positions in the scene coordinates of the corresponding axis' ticks. - ``labels`` (array of strings) - optional. Label displayed respectively to the `ticks` positions. If `labels` are not defined they are inferred from the `ticks` array. - ``digits``: number of decimal digits when `ticks` are converted to `labels`. - ``fontsize``: size in pts of the ticks labels. - ``show_grid``: boolean. If true (default) the axes grid is visible. - ``grid_opacity``: float between 0-1. Defines the grid opacity. - ``axes_opacity``: float between 0-1.

If set to True the scene object is serialized when the pane is created else (default) when the panel is displayed to the screen. This parameter is constant, once set it can't be modified. Warning: when the serialization occurs at instantiation, the vtkRenderWindow and the view are not fully synchronized. The view displays the state of the scene captured when the panel was created, if elements where added or removed between the instantiation and the display these changes will not be reflected. Moreover when the pane object is updated (replaced or call to param.trigger('object')), all the scene is rebuilt from scratch. r&r*r(a If true, enable the serialization of all data arrays of vtkDataSets (point data, cell data and field data). By default the value is False and only active scalars of each dataset are serialized and transfer to the javascript side. Enabling this option will increase memory and network transfer volume but results in more reactive visualizations by using some custom javascript functions.
