Directly below the main Menu Bar of ParaView you will find the Toolbar. On the Toolbar are some of the common operations. An example of the Toolbar is shown below. The appearance of the Toolbar will change based on Toolbar Settings that can be found on the Preferences tab of the Application Settings property sheet. In the below example these settings indicate a flat frame and flat buttons.
Based on the current state of ParaView (is there a current data object, and if so what type is it?) some of these buttons may be disabled. For example in the above image the last filter button is grayed-out indicating that it is disabled. This filter extracts a subgrid from structured data, and the currently active data object is polygonal which is unstructured.
The first three buttons in the toolbar control some common camera operations and are covered in the next section. The next ten buttons represent some common filters, and are covered in the Toolbar Filters section. The final four buttons control the center of rotation and are covered in the last section of this chapter.
