The Filters menu in the ParaView Menu Bar contains a list of filters that can be applied to the active data object. In addition, a set of filters are available from the toolbar. The list of filters available in the Filters menu and the set of filters that are active on the Toolbar will change depending on the type of the currently active data object. When you select an item from the Filters menu or press a filter button in the Toolbar, several things will occur:
The property sheet for the filter will be displayed. On this property sheet you will see the configurable parameters of the filter.
The Selection / Navigation Window will be displayed if it was not yet displayed already.
The filter that you are creating will be the currently active data object.
The filter will not be created and displayed until you press the Accept button, which is highlighted in red whenever a filter is first created or a parameter is changed that would require updating. If you would like to cancel the creation of the filter, press the Delete button. To reset all the parameters back to the default values (during creation) or to the values they had when the Accept button was last pressed (during modification) press the Reset button.
In this version of the documentation only a very brief description is provided for each filter. This will be expanded in the next release of ParaView.
