The Pipeline Browser displays all readers, sources and filters and how they are related to each other. Within the Pipeline Browser it is possible to toggle the visibility of datasets, add and remove datasets, rename objects, change inputs on filters, add custom filters, and copy/paste readers, sources and filters.
VisibilityIf a dataset does not have an eye icon on the left side, and the dataset name appears bolded, it has not yet been applied. Click on the Apply button in the Object Inspector to make the data visible in the View Manager. You can toggle the visibility of many datasets by selecting them all and left-clicking on any of the selected dataset’s eye. If the selected items have different visibilities, each dataset that is visible will be changed to non-visible and every object which has visibility turned off will be turned on. Another option is to right-click on one of the objects. The Hide All But This option will hide all objects not currently selected. The Show All But This option will hide all currently selected objects. If these options are used on the builtin object at the top of the pipeline, all dataset objects are affected. The builtin object at the top of the Pipeline Browser indicates that you are currently not connected to a server, and that the files are located on the local machine. When connected to a server, builtin is replaced with the server name. Note: If an object has been added to the pipeline but has not yet been applied in the Object Inspector, it doesn’t matter which object is selected in the pipeline, the Object Inspector will not display properties until all objects are applied.
Adding and Removing DatasetsThe datasets have to appear in the pipeline browser before they can be visualized in the View Manager. ParaViewGeo supports both single and multiple file loading.
Loading DatasetsWhen the datasets first appear in the Pipeline Browser, their names are bolded and the Apply button in the Object Inspector appears green. Click on Apply to generate the datasets in the View Manager. Once a dataset has been applied, selecting the object in the Pipeline Browser will display the dataset’s properties in the Object Inspector. Note: If the builtin object is selected, right-clicking in another section of the Pipeline Browser will not display a menu.
Deleting DatasetsReaders, Sources and Filters can be removed from the Pipeline Browser by selecting the object, right-clicking and choosing Delete Selected Object(s) from the list that displays. Multiple objects can be deleted simultaneously by having them all selected when right-clicking and choosing the Delete option. An alternate method is to use the Delete key on the keyboard, which will also remove the selected object(s) from the pipeline. Note: An object cannot be deleted if filters are applied to it. First remove the filters, or select the object along with its associated filters to delete them all at the same time.
Selecting ObjectsA dataset object must be selected before any changes can be made to it. Use the mouse to click on a dataset in the pipeline. The selected object will have a gray background, to indicate that it is the active object. When an object is selected, its properties appear in the Object Inspector. Multiple objects can be selected by holding down the Ctrl key when clicking on the dataset names. As of version 1.4.14, the selected object can be changed using the Up and Down arrow keys. The Up Arrow selects the previous object and the Down Arrow selects the next object in the pipeline. Also, the visibility of objects can be changed by clicking on the eye icon as indicated above, but if one or more objects are currently selected, the V key on the keyboard will also toggle the visibility.
Renaming ObjectsThe Readers, Sources and Filters can be renamed to more accurately reflect the data they display. To rename an object, select it in the pipeline and then click on the name again to enter the edit mode. Type in the new name and either press the Enter key or click anywhere in the pipeline to assign the new name. As of version 1.4.14, you can also right-click on the object and choose rename from the menu.
The pipeline clearly shows the relationships of the objects that are loaded. The connecting lines and indentations indicate how the various objects are connected to each other.
