The selected tutorials are used for illustration as in the documentation of the Turbo Unwrap filter. The filter transforms only cell data and if point data are needed (e.g. for usage of the Glyph filter), it is necessary to apply the Cell data to point data filter.
NOTE: the filters tend to disappear from their categories after use. This is a feature of ParaView, which moves the last used filter menu item into Filters > Recent. That list is, however, limited. Nevertheless, all filters are alwys accessible through the Filters > Search option.
