Indeed, the pipeline has been broken, so the refresh model no longer works. > How can I make the surface re-draw the new contour filter pipeline? How important is this? If it really is, you can always build your own subclass of Filter (mayavi.core.filter.Filter), that does everything right, in particular implements the 'update_pipeline' method. Maybe you can actually subclass mayavi.filters.contour.Contour. Anyhow, this will require some work. Maybe you can simple get away with registering a filter on 'data_changed' (or 'pipeline_changed', I am not sure), using the Trait's event mechanism: http://code.enthought.com/projects/traits/docs/html/traits_user_manual/notification.html#dynamic-notification HTH, Gael ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
