Utkarsh Ayachit Kitware Inc.

2 Selection

Selection

Mechanism to identify subset of a dataset Focus on selected subset Inspect properties of the subset Further process subset alone Track subset over time

3 Focus on subset

Focus on subset

4 Track subset over time

Track subset over time

5 Selection in ParaView

Selection in ParaView

What are we selecting? Data produced by a source Active Selection One application wide selection All views show the same selection if possible Creating a new selection results in removing the old one Transient: cannot be saved in state files, does not respect undo/redo.

6 Selection Components

Selection Components

Selection Inspector Inspect the active selection Spreadsheet View Inspect the selected data

7 Active Selection Inspector

Active Selection Inspector

Accessible through View | Selection Inspector Used to create/modify active selection Shows the properties of the active selection Control how the active selection is shown

8 Create new selection

Create new selection

Active selection properties

Selection type

Selected cells ids

Selection display Properties/Labeling

9 Spreadsheet View

Spreadsheet View

Used to view the raw cell/point data To create: split an existing view and select Spreadsheet view Display tab provides option to view only selected items

10 What is shown in the view

What is shown in the view

Show only selected items

Attribute shown

Select block to inspect

11 Selecting using 3D View

Selecting using 3D View

Surface cells/points Cells/Points within a frustum Blocks in a composite dataset

12 Select Cells on surface

Select Cells on surface

Used to select any set of visible cells on the surface of a dataset Representation should be points / wireframe / surface / surface with edges With 3D view active, use the Select Cells On tool button (shortcut S) to enter selection mode Click and drag to select cells

13 Select Points on surface

Select Points on surface

Same as selecting cells on surface except use Select Points On tool button.

14 Selection Linking

Selection Linking

Selection is linked among all views (whenever possible) Active selection is shown in all view (whenever possible)

15 Select Cells Through

Select Cells Through

Select all cells intersecting a frustum Use Select Cells Through Selection Inspector has a check button to show the selection frustum Use Select Points Through for selecting points

16 Select Blocks

Select Blocks

Select blocks in a composite dataset

17 Composite Datasets

Composite Datasets

Composite datasets are datasets comprising of other datasets. Group together assemblies: vtkMultiBlockDataSet Adaptive mesh refinement: vtkHierarchicalBoxDataSet

18 Select Blocks

Select Blocks

Use Select Block (shortcut B) to select blocks in a composite dataset Keep Ctrl pressed when clicking to add to existing selected blocks

19 Selecting using Spreadsheet View

Selecting using Spreadsheet View

Can create Point/Cell index based selections (depending on what attribute is being shown) Click to select rows as one would in any spreadsheet application Can use modifiers such as Ctrl, Shift while selecting Selection is shown in all views

20 Selecting using Selection Inspector

Selecting using Selection Inspector

Create new selections Convert selections id based to global id based frustum to id based Modify existing selection

21 Location based selection

Location based selection

Select cell enclosing the location or select point closet to the location within a threshold Created using the Selection Inspector and changing the selection type to Locations Provides widgets to specify locations

22 Threshold based selection

Threshold based selection

Select cells or points that have an attribute value within the specified range Created using Selection Inspector

23 Labeling Selected Items

Labeling Selected Items

Label selected cells/points using Selection Inspector Choose the array/id to label with

24 Extract Selection

Extract Selection

Extract selected subset for further processing Create Extract Selection filter Make selection and Copy Active Selection Hit Apply

25 Extract Selection

Extract Selection

Once a selection is extracted its treated as a first class data source. One can apply filters to it as usual. Extracted selection get saved in state files.

26 Plot Selection over Time

Plot Selection over Time

Plot data variable changes over time for a set of cells or points Use Plot Selection Over Time filter Make selection and Copy Active Selection Output can be shown on a XY plot

27 Plot Selection over Time

Plot Selection over Time

Changes for each cell/point selected can be plotted, one at a time, by choosing the block on the Display Tab

28 Conclusion

Conclusion

Selection provides mechanism to focus on a subset of the dataset Selection identifies the cells/points in the output of a filter/source Active selection is shown in all views (when applicable) Selection inspector can be used to create/modify the active selection Spreadsheet view can be used to explore the attribute values for the selected items Extracting a selection makes it possible to further processes the selected subset
