ParaView Comparative View Inspector
There may be times when a user would like to have more than one view of the data, for example in order to perform a parametric study. The comparative view inspector window can help you accomplish this. The comparative view inspector allows the user to arrange a series of 3-D views in a one or two-dimensional array.
- First the user selects the data they wish to operate on from the Selection Window. It will be highlighted when this occurs.
- The comparative view inspector can be turned on by selecting View->Comparative View Inspector.
- Under the Properties section, the
user can choose Film Strip or Comparative
- Film Strip allows the user to change a single parameter for each pane.
- Comparative allows the user to change two parameters. One parameter changes along the X-axis while the other changes along the Y-axis.
- The Number of X Frames changes the number of frames horizontally.
- The Number of Y Frames changes the number of frames vertically.
- The Selected Object changes which source, data, or filter will be modified.
- The Property to Animate changes which scalar value to animate.
- The Update button must be pressed before the output will be generated.
As an example, start ParaView and as described in the Multiview tutorial, change the window from 3-D view to 3-D view (Comparative) using the Convert To submenu. Next, create a wavelet by going to Sources->Wavelet. Click the Apply button to have the outline of the wavelet box appear in the 3-D comparative view. Next, using the Display Tab in the Object Inspector, or from using the pull-down menus in the toolbar, change the attribute to Surface and the data being displayed to RTData. As described above, bring up the comparative view inspector. In the comparative view inspector, change the Number of X Frames to 1, and the Number of Y Frames to 5. Under the Property to Animate menu, select to animate the Center(2), which is the Z-direction. In the spreadsheet at the bottom of the inspector, double-click on Center(2). This will bring up a menu that allows you to change the values. Leave the first value at 0 and change the second value to 10, and click OK. Finally at the very bottom of the Comparative View Inspector window, click the Update button. The display should change to look something like Figure 2 at the right.
