- A filter consists of one or more rules.
- Rules can be combined freely and require a condition.
- Operators are executed in this order: first “AND”, then “OR”.
- Filters are not saved with a scene. To reuse them, export the filter list.
The “Available filters” Area (A)
Your filters will be added to a drop-down menu where you can choose an entry and edit it.
Add new
If there is at least one filter defined you can create a new one with this button.
Remove filter
The selected filter and its rules will be deleted with a click on this button. This action cannot be undone.
Export List...
The filter list can be exported to a XML file, and shared or reloaded. Filters are not saved with the scene.

The “Selected filter” Area (B)
Filter name
This is a field where the selected filter name appears. When you uncheck “Auto” you are able to enter a custom name.
Auto
Uncheck this option to make “Filter name” editable.
Channel column
Here you will see the channel you want to use for the filter process, e.g. velocity, neighbours, density etc.
Drop-down menu (three short lines)
This icon is only visible after a click on “Click to add a new rule”. The menu contains a node's available channels, and therefore the entries differ from node type to node type. Select a channel and it will appear in the “Channel” column.
Condition
The drop-down menu contains all available conditions for comparing a channel agains a given threshold (“Value”).
Value
A rule requires a threshold and that is what you add here.
Operator
An operator will only work between two rules and the last operator will be ignored. Available options are “AND” and “OR”. Operators are executed in this order: first “AND”, then “OR”.
Trash can
Click on the icon to delete a rule (not the filter). This action cannot be undone.
Click to add new rule
A new rule is created with this button.
Keep elements that DO NOT match the rules
A click on this checkbox inverts the filter's rules, indicated by a “NOT” tag under “Filter name”.
Copy
All currently visible rules will be copied to the clipboard
Paste
Paste the rules saved in the clipboard.
